The Almighty Buck 186

An anonymous reader writes "C|Net has a story about the value of aging computer hardware, and the subculture of people who collect them. The story details some of the more enthusiastic collectors currently participating in the hobby, as well as their old-school beautiful hardware. '[Sellam Ismail] recently brought a quarter century-old Xerox Star computer back to life to be used as evidence in a patent lawsuit. The pride of his collection is an Apple Lisa, one of the first computers (introduced in 1983) with a now standard graphical interface. Such items sell for more than $10,000. In an old barn in Northern California that also houses pigs, Bruce Damer, 45, keeps a collection that includes a Cray-1 supercomputer, a Xerox Alto (an early microcomputer introduced in 1973) and early Apple prototypes.

Well, you'd have to get the first MacBook (the black one, obviously, and no Core 2 cheating), or maybe one of those Acer Ferraris or something. It would have to be something that is unique, yet popular and the most expensive first version. A custom built PC or a Dell is simply out of the question.

Well, not about the custom PC, but very much so in the case of the Dell.

You know what makes something interesting/valuable to collectors? Rarity. If millions of people chuck their Dells, but you keep yours, especially if you keep a set that shows the incremental development of the desktop PC over a few years, then that's a collectable.

A lot of people let old hardware slip through their fingers without wondering whether it might be significant. We are alive at the birth of the information age. And just as people happily threw away comic books for decades (Hugo Gernsback's back catalogue ended up being used as ballast in trans atlantic shipping, can you beleive that!), we're chucking out 'useless' hardware now.

God I wish I still had my 3DFX Voodoo 1.

Re:wrong (3, Insightful)

rbanffy (584143) | about 7 years ago | (#18740631)

It must be rare _and_ interesting.

A dull Dell box (pun intended) is not interesting unless it has a unique form factor.

That 21 inch screen notebook monstruosity is such thing. Buy it and keep it functioning for the next 30 years and you will have something. There was also a Compaq desktop with a built-in LCD. I have a Monorail PC that still boots - it had it's HD and CD-ROM changed because they no longer worked. There is also a Sony Vaio whose keyboard folds up to cover half the screen as it becomes a stereo. There were a couple Compaq models with integrated monitors that were interestingly iMac-like.

Those are interesting PCs. No grey box, no matter how rare it is, will ever become interesting.

Anyway, most interesting computers are not PCs. A Sparcstation 1 is interesting as is a Voyager. Just about every SGI box is somewhat unique. If you are shopping today, buy a Tezro. If you want a Sun, buy a desktop SPARC (the amd64s are just PCs). IBM RS/6000s are a bit on the PC side, but are OK. Apples are very diverse and an interesting piece of study. The "flex-chassis" series is very interesting because of the modular mobos. The tower G3 is interesting because every time you open it, it draws blood from your hand. An IBM 3290 terminal is unique as it had a red plasma screen. An NCD 16 X terminal is interesting because of the square CRT. Any Lisp Machine is worth having. The Convergent non-PC x86 machines are very interesting as is their OS.

Rarity is for newcomers that don't really get it. It is a tool for those who can't see the other forms of value and for those who do to get rid of rare and dull hardware.

No article such as this is complete without a link straight to the Classic Computer Mailing List [classiccmp.org], with its high volume of discussions, finds, swaps and technical solutions.

A couple of years ago I was involved in the dissemination of a collection in the south-east of England. From the PDP-11/43 that had people offering to drive over from northern Europe, to the blue Intel MDS to Spain, the old Dragon to America, the stalwart CJE Micros grabbing up the BBC's Torch coprocessor, to the steady stream of people each collecting a VAX, it was amazing to see the interest and enthusiasm.

Three nice things about old machines:
(1) Simple enough that a single human can understand how they work;
(2) Scaled such that this same human can fix problems in his garage;
(3) Sufficiently well built that (2) can sometimes be unnecessary even after 20 years.

Oldies (1)

Spacejock (727523) | about 7 years ago | (#18739327)

I have a large collection of Sinclair gear, from a bare ZX80 though a number of ZX81s (with and without Rampacks) to most models of the ZX Spectrum, from the original 16K to the +3 with built-in 3" disk drive. Microdrives, tapes, ZX and Alphacom printers, light guns, Currah u-speech and on and on.

It's purely nostalgia, not a money-making venture. My first computer was a ZX81, saved up for and bought new 24 years ago, and I still remember it like it was yesterday. (In fact, I still have it.)

Re:Oldies (2, Informative)

Jeff DeMaagd (2015) | about 7 years ago | (#18739569)

Money making shouldn't be the goal because there's a good chance that it would fail at that. That is the nature of all forms of collecting.

It is often hard to predict what will succeed. If it's an interesting but rare device, then there are chances. If it's interesting but not so rare, then your only chances to make money are if there's demand because there's a common failure mode and hope that yours doesn't succumb to that failure. If it's just rare, then there's little chance unless you find a collector that wants to complete a series of that type of device for some odd reason.

davemc168 (998032) | about 7 years ago | (#18739587)

In another 30 years your machines will fail because you cant get an analogue TV to show them on, the frequencies will have be re-used and everything will be digital. There may well be a DRM busting convertor which it will be illegal to own though :(

Re:Oldies (5, Informative)

Alwin Henseler (640539) | about 7 years ago | (#18739811)

In another 30 years, many of these oldies will have died (if they haven't already) due to a variety of reasons. Mostly plain mechanical parts (cheap plastic, foil keyboard switches, rubber rolls crumbling and so on). Also think of programmed parts (EPROMs, programmable microcontrollers included for a specific task etc) that go into an erased state after a long, but finite time (usually several decades).

But if your machine still works after 30 years, plugging it into a monitor won't be the hard part. Last time I checked, even many of the latest LCD TV's have a variety of analog inputs. Why? Because analog inputs are often useful to hook up monitors to the widest possible variety of replay equipment. Even if many modern equipment is 'digitised', you're a fool to think that the option to display analog signals will disappear completely. Think of analog signals in general as a lower-level thing than most digital signals, meaning it's easier to do something with it, and easy to include in display equipment at near-zero added cost.
With audio, things are even easier/simpler.

For example this Sinclair ZX81 produces a TV UHF signal, but it's easy to pick up a plain composite video signal from its insides. Some soldering of wires might be required, but I expect you'll have a hard time finding a brandnew LCD TV that is not capable of producing an image with that.

One thing I personally like about these early Sinclair machines, is that they're built simple enough to recreate them with plain discrete logic, and perhaps a few analog parts. No complex video circuitry, no audio, a well-understood CPU and so on. Enough for instance to program a FPGA to behave like a ZX81 (try Google [google.com] if you're interested). Also makes these machines relatively easy to repair. For ZX81: if you got the time, tools and knowledge, you can repair/keep these machines running as long as you want. I myself own 2 of these, last time I checked both were still working. 25 years old by now, and I'm pretty sure I can have these in a working state longer than a PC bought new today.

An original IBM PC would be perfect for teaching someone advanced programming.

  • Instruction timing-based optimization - Check
  • Drawing lines by directly altering video memory - Check
  • Disk and memory data structures - Check

    On a modern computer, everything is wrapped into so many of abstraction that you can not discover how it works. It will take someone 3 years of experience to create a device driver or a graphics library that can be understood in 3 weeks on an old PC.

You know, these new-fangled computers that we have can be started in 16-bit mode thereby acting just like an original IBM PC, but gigahertz faster. What you mean to say is that modern operating systems abstract everything for you. You can still boot these new computers into DOS if you wanted to and remove all of that abstraction. On the other hand, there's a good reason most people left DOS behind...

Re:Best for learning programming (4, Insightful)

iamacat (583406) | about 7 years ago | (#18739603)

These gigahertz are actually a problem when learning certain topics in programming. How can one explain the value of Bresenham's line algorithm when a for loop using floating point appears just as fast? There is a huge learning value in running into limitations of the hardware and either optimizing your code or redefining its goals to solve a simpler problem. Something Vista engineers need to learn to avoid making a dual core machine crawl.

Re:Best for learning programming (4, Interesting)

arivanov (12034) | about 7 years ago | (#18739677)

You missed one of the GP points: instruction timing based optimisation. You cannot teach that on a modern machine (most you can no longer turn off the cache) even if you boot it in 16 bit mode. The last machine to allow this and have a well published instruction set was 286. 386SX was still useable, but the stuff started getting muddled. 386DX (all but the earliest cacheless samples) - unusable for this.

Similarly, from Pentium 3 onwards the APIC has changed drastically so the interrupt controller handling is no longer the same. Granted, you can run it in backwards compatible mode, but it is not the same.

Similarly, IO on PCI devices is clearly nowhere near the original IO on x86. While there is some backward compatibility present, you have to go and do at least some bridge programming to get anywhere. That was not the case with any of the 8 and 16 bit IO on systems all the way up to the early 486-es. You could manipulate every device separately ignoring most bus issues.

Overall, nowdays if you want to teach anything low level you have to go to a simpler architecture like one of the 32 bit MIPS architectures. x86 in its current form is too complex to be useable even for an advanced college level architecture and drivers class.

Re:Best for learning programming (5, Interesting)

TheMoog (8407) | about 7 years ago | (#18740193)

In the computer games industry it still pays to know your way around cycle counts, pipelines and caches. Just because your device has a cache, and you're coding mainly in an OO language, doesn't mean to say you've left the world of cycle-level optimisation behind. And particularly on Sony machine it's almost a requirement to fully understand the various hardware interactions in order to get a decent turn of speed out of it.

As an industry we're now finding it very hard to employ people who know this kind of stuff. Most graduates are taught Java or C++ and have no decent experience at the assembler or hardware level. Now I'm not saying that we spend all day hand-crafting assembly code - games are just far too big nowadays - but every now and then you'll get an unusual crash which can only be debugged using knowledge of the hardware. In my experience CS graduates just freak out when you show them a disassembly of their code!

Re:Best for learning programming (1)

Alioth (221270) | about 7 years ago | (#18739629)

Probably best to go for even simpler than that - an old Sinclair Spectrum does all of the above, and it's small enough to be completely understandable in a short period of time. Plus Z80 assembly language is a bit nicer than 8088 (even though the ISA is related).

romiz (757548) | about 7 years ago | (#18739651)

To learn system programming, it is a bad deal compared to a microcontroller with an emulator, or even a refurbished GBA with a flash card:

  • Interrupt handling - Check
    With only 15 interrupts lines, cascaded into 2 8-lines banks, the IBM PC is quite limited, and you still have the trouble to handle the cascaded handlers.
  • Instruction timing-based optimization - Check
    But if the 8086 processor understands a subset of the complete assembly language from the current PC, the timings constraints are completely different: the cost of an instruction for a 8086 accessing directly the main memory completely changes as soon as you have cache, which is essential for modern computers. And with the mess that x86 assembly is, I'd prefer dabbling with ARM assembly instead.
  • Drawing lines by directly altering video memory - Check
    OK - but it is not alone on that segment.
  • Disk and memory data structures - Check
    Disk structures ? The cylinder/head/track abstraction that come with the floppy disks is compulsory on old IBM PCs. The LBA method is much more straightforward. No one should need to learn a complex, obsolete abstraction that doesn't even correspond to the reality anymore.
  • And in complement to that, it is impossible to debug from the outside. With embedded platforms, you can write the code with your PC, test it in an simulator, and then test it on the platform with an In-Circuit Emulator to check for bugs. You can't do that on an old IBM PC.

What I did was wrap it carefully in plastic and seal it up so it was airtight, then packed it away. It's still waiting for me to take a look at it, however that may be in many years from now as I have too many other projects.

Old DEC gear (4, Interesting)

MichaelSmith (789609) | about 7 years ago | (#18739407)

...used to sum up my job. We used to get spare PDP/11 parts from people like the those in the article. The DEC maintenance guys at the time told me about a factory they knew about which relied absolutely on a PDP/8. Service calls there were a challenge, to say the least.

Towards the end of my stint at Vic Roads the foam padding stuck to the top of the slide out boxes on the 11/84's had turned to dust and collected around the base of all the mux cards where they go into the backplane. Swap out a card and spend the next couple of hours vacuming out the backplane to get it working again. Installing a SCSI card was a challenge. You slide out the CPU box and get yourself organised by lying flat on your back underneath it. Like taking the transmission out of a car. The you identify the wire wrap cable for the slot which is going to take the card and repatch the appropriate interrupt line. On some of them you were lucky, there would be little shorting patches which you could pull off, like on the back of an IDE disk. Don't muck up the backplane in the process because people need traffic lights, you know.

I've got an ohio scientific superboard 2 in my spare parts cabinet. As long as I can still find a TV which listens to an RF modulator I am free to run up the micro assembler and hack away. My son is 5 now. In 7 years he will be the same age as me when my dad built that machine up.

Reminds me of the time I was working on a major defence radar site. The main array was steered by an ancient 6800 microprocessor based system built around a backplane. A couple of hours before the airforce was due to do an exercise I made the mistake of pulling a card out of the backplane (we were reverse engineering it to modify the software, whose source had been lost in antiquity). It turned out the backplane had hairline cracks all though it due to the flexing caused by plugging and unplugging cards over the years. When I put the card back in the system failed to boot.

I was frantic as the radar was absolutely cactus. This microprocessor routed *every* signal to and from the main antenna array and a front line early warning radar system spanning a continent was dead in the water. I ended up fixing it by simply inserting and removing the card lots of times. With minutes to go, I fluked it that the system booted (meaning the hairline cracks were closed). I then *very carefully* put the front panel on and walked away from it. A few minutes later the airforce people walked in and started their exercise. As far as I know the system is still in that state.

The joys of ancient backplanes.

Old Computer Worth More For Software. (1)

chromozone (847904) | about 7 years ago | (#18739413)

My Gateway 500S that cost $1250 in 2002 won't even bring $100 on ebay. I haven't tried to sell mine but I watched a lot of others try and fail. I think after 3 or 4 years the computer is only worth about what the software might cost new. Speaking of which, I was reading that XP won't be sold next year and maybe that will boost the price of some of the old machines since people might want XP again. I can't speak for all of Gateway's computers but the 500S was a stud (and Consumer Reports best buy) and mine still works great. I might pick up a couple more since they cost about what a copy of XP home would cost new anyway. I still don't even have to activate with Microsoft when I reinstall my XP from the 2002 Gateway so I was wondering if its easy to transfer OS to new machine. Old versions of XP might be nice to have.

I don't think your computer is even in the same category as what the article is about. You're talking about a perfectly useable machine that I would be glad to find in a dumpster (as a matter of fact, I already found better computers in the dumpster)

These people are talking PDP machines, Crays, and more in the home segment Commodore 64, Apple Lisa, Sinclair QL, Sinclair ZX, etc... Perhaps even stuff like the SparcClasic or an Octane. Perhaps the original XT is of insterest to them or even an MCA PS/2....

I used to have a few old computers (namely a SparcClassic, a Sinclair QL and an IBM PS/2 Model 50). I all gave them away to a teacher that wanted to start a computer museum. Why? Because, they take place in my basement.... I would have loved to use them, but I'm married and have other priorities.

Oh, and about the software. That XP that came with your Gateway is an OEM version tied to your machine. Even if you manage to transfer it to another machine, you are pirating it. OEM XP is pretty much worth nothing.

I was running my webserver on an IBM thinkpad, P90 with 32Megs and 1gig harddrive but I just found an old rack mount server which is an old Pentium 133 with the F00F bug, it has 32Meg and a 4 gig drive. It's used to feed static web pages and as a picture and file server. It's a generic rack mount of some sort. Eventually it will get gutted and made into a more modern media server with a terabyte of storage. Unless someone offers me 10k.

The Thinkpad may be left unmolested though I'm considering making it a digital picture frame.

Re:Use them around the house. (2, Interesting)

jawtheshark (198669) | about 7 years ago | (#18739785)

Yeah, that all fun... I do the same thing, but this is not the category of machines that these people collect. Wintel machines aren't even in the picture. Sure, I had a P-166/256Meg RAM functioning 24/7 as a home server. I decomissioned it when motherboard/cpu combos became so cheap that I could replace it with modern components for pretty much no money. Today my home server is an AMD64 2800+/512Meg RAM. It also doubles as a space heater ;-)

Today, I wouldn't even spend money on such a machine because I started to find very capable computers in dumpsters. P-III 1GHz become very common (my parents server is a P-III 800MHz, which was my old desktop). The occasional Athlon and P-IV can be found too. x86 machines are so ubiquitous that they are not worth collection in any way. If you still have one, it is either your primary computer or you have a small home server.

The newest computer in my household is a laptop: barely 3 months old and bought before the release of Windows Vista. Why? Because it was on sale ;-) My wifes desktop is from late 2003 and mine from early 2003 (though I invested in a workstation class machine, not a consumer-end machine) Neither machine is even planned for retirement. I maxed both out on RAM and they shug along just nicely for all our tasks. Mine runs Debian, my wifes machines runs Windows XP Pro.

I know as a matter of fact that Windows XP Pro runs fine on a P-III 600MHz/512Meg RAM for mundane tasks. That's what my mother in law uses and that is what my last laptop was.

My baseline for "old" in the x86 world is a P-II class machine. Not that they are not capable of doing any worthwhile work, but because there are faster machines available for 0€. Those machines and below are only worth to be deposited in a dumpster. Now, non-x86 machines... Those are pretty much all collectible ;-)

Demo scene (3, Interesting)

cerberusss (660701) | about 7 years ago | (#18739597)

These oldies are regularly used in the demo scene. A colleague of mine regularly visits demo parties where up to 250 geeks gather to show each other their demos. He owns a souped-up atari with a custom board driven by a custom-made FPGA containing 2 Gb memory.

Although reportedly, even in the demo scene there is an on-going shift to PC hardware. The Amiga and Atari lovers are getting smaller.

On another note, he told me that when his group returned from a recent demo party by car, they noticed the little mileage markers (marking every 100 meter on European highways). They drove and counted 133.5, 133.6, and then saw that 133.7 was gone :-)

Re:Demo scene (3, Insightful)

Animaether (411575) | about 7 years ago | (#18739979)

Indeed, the PC (IBM AT compatible blabla) demo scene has been *extremely* active for as long as there have been PCs. Check www.scene.org for details/demos.

However... there's no longer such a thing as 'The PC Demo Scene'; even those who claim there is are realizing it is rapidly degenerating. The reason for this is the extensive hardware acceleration of any type found in PCs these days. It used to be a challenge to stick a procedurally generated 3D scene with an 8-track MOD in a small exe and have it run fluidly on a 386 with a basic VGA card and a SoundBlaster. Nowadays one just takes the regular 3D scene along with an MP3 and feed it to the graphics card and through a simple decoder straight to audio.

From the Gravis UltraSound to the S3, every hardware development was greedily taken advantage of by showing new things that could be done on that hardware... but they've reached a saturation point several years back. If you want to pump the best results out of a graphics card now, you're not doing so in a demo.. you're doing so for profit on a major game engine.

What is left, then, is a limited form of a PC Demo Scene.. demos under 4k, 16k, 32k and 64k (existed before, but these are still challenging now even with all the hardware).. demos that must run on older hardware.. self-imposed restrictions like "no using pixel shaders", etc. But these are all highly artificial limits and no longer push the boundaries of what one can do on the hardware as is... it's pushing the boundaries of what one can do within those artificial limits.

To some that is the same spirit, to others it's nothing alike at all.


To see what people are doing with PC demos nowadays, Farbrausch's debris is a nice one to check out. You don't need the hardware to run it, there's videos made of the things.

Yep, I'm just back from breakpoint in bingen (close to frankfurt) germany (swede myself) last easter.

There was one demo for atari vcs, two for zx spectrum, one for atari xl/xe, one for the msx, one for ti-83 but also newer consoles as nintendo ds, gameboy advance, xbox 360 and psp etc... And in amiga there were 8 demos and 8 intros (6 64kb and 2 4k limits) and in the c64 there were 6 demos... check them out at http://www.pouet.net/party.php?which=450&when=2007 [pouet.net]

But of course there are also pc competitions, and the one that stood out was debris [pouet.net]

Demoparties are mainly a european happening, even tho there are visitors from all over the world. Especially to breakpoint and assembly.

I used to collect this stuff. Well, not Crays, but retro computer hardware. Fun as it is to buy for $5 a Sun Sparc server that would have cost more than $10,000, there's a reason why this stuff is being chucked out. It's a waste of space. And if you plug it in and turn it on, it's also a waste of power.

Now, if people have enough space to start their own personal museum, I'm not going to tell them not to. But if you're an ordinary person with an ordinary house, you're better off putting them on the verge for the next council bulk rubbish collection.

Obsolyte! (4, Informative)

tekrat (242117) | about 7 years ago | (#18739769)

As a collector of some of this old hardware (See my website, http://www.obsolyte.com/ [obsolyte.com] ), I can tell you that for every "gem" you find, you also aquire about 2.5 tons of useless crap. It's very difficult to figure what machines will become the iconic collectables, and which ones will just be considered trash.

The Apple Lisa is highly prized (although at one point, Apple was filling landfills with 'em and Sun Remarketing was selling what remained for $200 a pop), but the Mac 512k is pretty much ignored (although the original 128k Mac is valuable).

I have no idea what my old NeXT-Station is worth, but, it'll never be worth what the original Cube is. I have a pretty decent collection of SGI gear, but, does anyone care about SGI at this point? If you look on ebay, people can't even give that stuff away.

And while the Amiga may be the greatest computer ever made, you'd have trouble these days selling your A2000, no matter how tricked out it is (free Video toaster!). The Amiga collector market is saturated, anybody that wants an Amiga probably already has more than 2.

And you'll still find the venerable C=64 and Apple // at garage sales across the country, although, very likely missing key components.

Of course, should you have an original Altair in your basement, that's another story entirely.

I Haven't Got The Patience (1)

pandrijeczko (588093) | about 7 years ago | (#18739905)

I'm not in the same league with the guys that collect the old Crays and DEC PDP11s but I went through a phase about 4 years ago of collecting both Sinclair ZX Spectrums and Commodore Amigas from eBay, both machines that I owned during my younger years - I even got given an Acorn Archimedes and a RISC PC by people who heard I was into old computers.

For a while it's great fun sorting through boxes of Spectrum tape software and Amiga disks and reliving some good gaming memories - but when you get to 25 "TAPE LOADING ERRORS" in a day, in can get a bit wearing.

Suffice it to say, about 2 years later I sold it all back on eBay for about the same money I paid for it. I still love the old games on those machines, as well as the C64, but these days it's far easier to play them in a PC emulator.

I admire the guys who collect as a hobby but I couldn't find enough hours in the day to do it.

Re:I Haven't Got The Patience (3, Interesting)

thegrassyknowl (762218) | about 7 years ago | (#18740099)

I don't have the time anymore. It's hard work being a full time employee for the man and raising a family and commuting an hour to and then from work because the man doesn't pay enough to live close to work (yet he pays himself enough to live in the most expensive suburb, another rant entirely).

I used to collect Commodore and Nintendo stuff. I have a pretty good collection of Nintendo hardware; NES, SNES, N64, a handful of games, extra controllers, light guns, the works. I even have the beginnings of a Sega collection. It's all operational as well after a lot of cleaning and TLC. It takes a lot of time to resurrect the older hardware and make it functional. If you don't have the tech skills to replace fried components or even repair damaged PCBs and connectors its really not worth doing. You often buy two or three dud machines to turn them into one functional one.

There's no point having a machine if you don't have a decent collection of software to run on it. Sure, you can often download the software illegally but for cart-based systems then you need to find a working cart emulator, assuming one existed for your platform and you still can't play anything with SuperFX-type addons on cart emulators.

Collecting the retro stuff is also time consuming. You have to be on the lookout everywhere. Ebay is good, but there's a lot of crap on there that people are trying to flog off for more than it's worth. I see a lot of stuff that says "condition unknown" then with a min bid of $50. That could mean it's totally fried but you have to decide whether to take that gamble. There's always stuff advertised in the local trading rag and the local news, as well as other websites and swap meets that come and go. If you don't keep abrest (all you nerds tremble before the breast) of current prices you're lialbe to get royally screwed.

I sorely miss being able to play some of the games that I played as I was growing up, but I remember back to when I used to play. We'd sit up all night hammering away at the game. That was the only way. When you're on a limited time budget (as you are when you're working for the man and have other commitments) you can't do that anywhere near as often as you'd like.

Good luck to those who want to get into the collection hobby. It's fun and rewarding. If you just want to hoarde junk stay for the sake of being able to say "i have that" without ever actually doing anything with it then you should probably find another hobby; there are some of us who like to restore hardware and it's difficult to do unless you can get enough bits. If they're getting snapped up by hoarders then it takes the fun away for a lot of us.

"Custom" Spectrum (1)

lbbros (900904) | about 7 years ago | (#18740091)

Among the computer antics I own (not many actually) there's a "custom" ZX Spectrum +. Why custom? Because my father was fed up of me and my brothers hogging the TV with that thing, so he bought a 10" monitor. Of course it couldn't be attached directly, so he got an I/O interface and by soldering cables directly on the mainboard(!) he got the video signal in a cable that he connected into the I/O interface. As well he did the same for the mic in and ear in inputs. The I/O interface had a DIN-like connector that was compatible with the monitor, but the signal was poor, so he added a power supply to the I/O to reduce the signal decay.

This thing worked perfectly until I stopped using the Spectrum in 1988.

Profit, really? (4, Insightful)

Anonymous Coward | about 7 years ago | (#18740241)

I can guarantee you that maintenance of such machines over 30 years has cost more than $10,000. If for no other reason than the real estate that they occupy. It is Silicon Valley after all. Rent out that room or shed you keep those heaps of junk in and you'll have $10,000 in 2 years rather than 30.

Think of it this way. If I told you that I wanted you to keep your current computer and all related peripherals for the next *30 years*, in working order, how much would I have to pay you to do that? I bet you'd ask for a lot more than $10k.

Same goes for any "collector's" item. People are amazed that a #1 issue of a golden age comic book will get $5,000 and up, and talk about it like it's an extraordinary profit for the seller. Ok, here's $5,000 -- now keep this piece of paper in pristine condition and obsess over it for the next 30 years. Sound like something you'd want to take up?

Yes, the prices are high but that doesn't imply profit by any human measure of economy.

I have a thing for Sun Sparc 20's -- they are VERY upgradeable and extremely reliable. Two of mine have quad 150mhz Ross processors making them snappy ehough to serve out some Apache/PHP/MySQL, host a little e-mail for a few domains, and do some secondary DNS. They're small, don't use a TON of power, and just plain cool.

Oh, and they'll run Linux or a few of the BSD's just fine..

I have ipcop running on a pentium 133 laptop as my gateway/firewall. The battery holds enough charge to stay up for a few minutes when the power flickers. With the display built right in I don't need a monitor sitting there. I can turn off the display when I don't need it. I leave it on 24/7. It consumes about 13 watts of power at idle (via Killawatt*). It's a little pokey on the web pages, but uses very little CPU otherwise.

I was using a P266 laptop behind the 133 for a while and stripped down a knoppix install to run:
- httpd
- sshd
- samba
- openvpn
- fetchmail
- dovecot
- spamassassin

I adjusted most of the config files to lighten the load on the 256M of ram, but as I added more services it was just too much for it and stuff was getting sniped by OOM killer; nice experiment for a couple years though. Linux is adjustable for old crappy hardware which cant be said for windows (or apple for that matter).

Don't know about you guys, but I keep a Silicon Graphics Indigo2 R10K 195MHz/MaxImpact [wikipedia.org] workstation under my bed for my own nostalgic purposes. Back in my college days, the machines were so obscenely expensive (around $40,000 per unit), you had to have special security clearance just to get near one, let alone the room with all eight units.

Of course, the system itself has lost much of the luster over the years, when you consider that current desktop computers (and even game consoles) are able to do in realtime what would have taken several days/weeks to achieve on the older hardware.

Yet, it's still satisfying to know I finally have one of the very machines I once envied others for having access to.

recyclers and colector items. (1)

3seas (184403) | about 7 years ago | (#18740983)

Pretty much if you go to an electronics recycling event and see what others are tossing it'll probably make you see that you've collected alot of junk. But the important thing is to recycle the junk properly.

That can be hard to do even if you find a free recycling event as they may be limited to once a year and only for a part day (not 8 hours).

If you are a serious collector then you've done your research as to what is worth keeping and know the cost of maintainance as moving hardware components can deteriorate over time and non moving components are subject to deterioration too, just takes longer.

But what is really needed is a fast and small OS that can easily be ported to the otherwise "junk" to bring a bit more life and use to it before its final destination of landfill of recycling by better methods.

There are some small and fast OS... More than the ones I know about, Minix 3, AROS, Damnsmall Linux, etc.. and there is new hardware that allows FPGA programming of emulations of some of the old system, hardware such as the C=ONE.
