enalbro writes "What wouldn't you give for a laptop that starts instantly, weighs 3 pounds and gets 20 hours of battery life? That's the TRS-80 Model 100 in a nutshell. Granted, it displays only 8 lines of text and has just 28 kilobytes of memory, but it's a classic, the first truly popular portable in the U.S. At PC World we have a teardown that'll show you the guts of this featherweight champ." And, like many of the best things in life, it's powered by AA batteries (as is the Apple eMate).

Bought two used ones a long time back (4, Informative)

One of which the previous owner had ran over with her car. Except for the missing LCD (was cracked) the unit worked; keyboard and all.

Had a nice little BASIC and lots of cool ports. Trivia: the OS was the last major coding work by Bill Gates himself.

We had one that my dad left in the trunk of the car for about a week in the summer so the keys partially melted. It was hard to type (you really had to pound on a couple of the keys to get them to register) but it still worked like a charm. Now I worry about my Dell laptop on humid days.

Ooblek (544753) | more than 6 years ago | (#23640929)

A friend was cleaning out his garage once and had one of these in a box. He gave it to me. I like tinkering with antique computers on occasion. (I still have my C64 programmers handbook that has the fold-out motherboard schematic in the back.)

A few years later, I velcroed it to a pull-out rack shelf and hooked a null modem cable to it to monitor the console output of a SSL Screen Sound setup (proprietary pro-audio digital mixer/editor in the days before Pro-tools). It couldn't quite keep up with the 9600 baud stream if there was a lot of data streaming fast like during bootup. It did the trick, however, when you just needed to go in and check some of the statuses while the system was running. I think I mostly used it to go in and low-level format the hard drives on occasion.

It was useful for a while, and that must have been somewhere in the mid-90s that I used it.

From page 4 of the article: "Peeking in from the left is the reset button, which the user needs from time to time due to a few pesky bugs in the ROM code, reminding us that even non-Windows systems can crash." I guess the quality of Microsoft software has stayed the same as the days when Bill was writing code.

GK Chesterton (1)

bsDaemon (87307) | more than 6 years ago | (#23640573)

GK Chesterton once wrote, 'there has never been a revolution that was not a reinstitution' - or something very similar to that.

With the new crop of machines like the EEE PC it seems that we're moving back to small, power-efficient machines as opposed to huge hulkers.

Hopefully, as people become more conscience of the cost of energy, both in economic and environmental terms, we'll see more applications of low-power consumption chips like ARM and 20hours of battery life won't seem so amazing anymore.

Tumbleweed (3706) | more than 6 years ago | (#23640667)

With the new crop of machines like the EEE PC it seems that we're moving back to small, power-efficient machines as opposed to huge hulkers.

With OLED screens coming as the next big thing in the next few years, processors like VIA's Nano (formerly Isiah, I think), Intel's Atom, SSD storage, integrated graphics, things are definitely looking up on this front. Along with fewer moving parts to improve useful life, this is all great news.

I just hope the usability improves as well. Keyboards like on the Model 100 have a *much* better feel than any modern laptop I've used.

I read an article the other day about some big advance coming up for Lithium-Ion batteries, so that'll be nice, too. :)

Those are by far the best laptop keyboards I've ever typed on, and I greatly prefer them to most rubber dome keyboards. (However, I prefer a good buckling spring keyboard.)

People have been predicting the death of the hulker desktop now for what, 10 years? Sure the move to smaller and efficient is what's going to make computing truly ubiquitous by hiding them everywhere (well, that and economics), but full-sized machines will always have more power and reflect the state-of-the-art computing muscle the industry has to offer.

But muscle isn't everything? Lalalala, I can't hear you. ;)

I plan on experimenting with Pico-ITX, or perhaps ARM systems this year, trying to see if I can't power a reasonably useful system on solar or so. I probably wouldn't want to be doing a buildworld every week on one, but it'd be nice to have something power efficient to idle IRC...

there is always going to be a place for hulking, massive systems -- however, we should try and make them as power efficient as possible.

Or indeed any keyboard. My Windows and linux PC keyboards have always had the control key in the right place.

I used to swap the caps lock and control keys, but since I never need the caps lock and since occasional users of my keyboard get confused about the layout, I nowadays just turn the caps lock key into a control key and live without a caps lock.

I have a first revision Commodore 64 with a keyboard like the TRS-80 Model 1000's. If it's all the same to you, I'd rather keep my flat-key MacBook keyboard. Typing on the C64 is not something I'd like to do on a regular basis. But typing on my MacBook? That is something I already do on a regular basis.

Sorry, but nostalgia is not a good stand-in for real-world superiority. (And I say that as a classic video game/computer collector.)

"Sorry, but nostalgia is not a good stand-in for real-world superiority."

I sense a great disturbance in the Force, as if thousands of Model M users cried out in rage, and then continued typing.

Re:keyboards (2, Interesting)

AKAImBatman (238306) | more than 6 years ago | (#23641051)

The difference is that the Model M really was an excellent keyboard. With every key exceptionally well sprung, the keyboard was so heavy you could kill someone with it. (Hmmm... Colonel Mustard did it in the office with the keyboard?) Yet the keys were very responsive, well spaced, and easy to type on. I'm not sure I'd go as far as to demand that all modern keyboards should emulate the Model M, but it was a good keyboard.

Re:keyboards (1)

Tumbleweed (3706) | more than 6 years ago | (#23641125)

Your point would be good if a C64 keyboard was actually like the TRS-80 Model 100 keyboard. It isn't, though.

I have a MacBook on my desk next to me at work, and that keyboard blows. All form over function. :(

Apple is hardly alone in this, though, as Sony proves (and that Optimus keyboard).

Re:keyboards (0)

AKAImBatman (238306) | more than 6 years ago | (#23641655)

Looks like the same keyboard design to me. High impact plastic keycaps mounted on through-hole plastic posts, sprung with a small spring around the post. IIRC, the contact for the key is on the bottom of the post on the other side of the board through which the posts are threaded. (The plastic posts are usually + crosses to ensure that they don't exert unexpected torque on the keycaps. Also, the shape helps secure the keycaps as pressure is the only thing holding them on.)

The problem with this design is that a key that is not struck correctly (e.g. you hit the side of the key, or exert pressure in a direction other than straight down), friction can develop between the key and the board underneath. The post may even lean sideways during the strike. Since everything about the keys is designed to prevent this, the key effectively locks in place and the strike is missed. Thus the keyboard requires a certain amount of training, and is only effective when used from particular angles. (And with laptops, the angle of impact can change regularly.) This problem can be mitigated by striking the key harder to push past the sticking point, but why? Modern keyboards like the ones in the MacBook do just as good of a job with less force. They have a good feel about them, make it easy to find keys based on tactile feel, and generally are nice to type on.

If you're used to the keyboard on a TRS-80 Model 100 (which I'm amazed no one has drug out the infamous tag-line of "Trash 80" yet) then you won't notice the many quirks of such old keyboard designs. However, they are there, and they do frustrate modern users. Which is one of the many reasons why modern keyboards look nothing like those of the TRS-80 and C64 eras.

As I said, nostalgia is not a good stand-in.

Re:keyboards (1)

OakDragon (885217) | more than 6 years ago | (#23641161)

Looking at some of the replies, I guess some people just like typing on those flat, no-travel keys. Myself, I love the "ka-chunk" that the M-100 provides. It's also superior to many "regular" keyboards you can buy today.

I suspect that modern laptops keep their keyboards slim so as to keep the units slim as a whole. But I would gladly sacrifice a the slim profile for a "real" keyboard.

Probably, plus for the fancy looks. I'd love for Lenovo to put a buckling-spring keyboard in the ThinkPads. Hell, you could probably put a little generator in each key and partially power the thing just with your typing! :) Then if they made it cheaper, I could maybe buy one. Someday.

He's almost two, and has fun banging away on it...any time he starts making his way toward my laptop, or my wife's, we just say, "Hey, where's your laptop these days?"

Only problem is, my wife has an iBook, and once he notices that his laptop isn't nearly as shiny as hers we're doomed. Lucky thing I'm a Linux sysadmin...I can just point to an xterm once he starts wondering about the difference between his laptop and ours. :-)

corsec67 (627446) | more than 6 years ago | (#23640699)

Granted, it is older than I am, but it is indeed quite impressive. My parents gave it to me when I was about 10 years old. Since I wanted to play games on it, I had to type code in from a book.

Instant boot. Sunlight readable display. Full travel keyboard, full size keys. Ctrl key in the correct place. No screen joints to wear out.

20 hours, on 4 AA batteries. No proprietary battery.

External storage is an audio cassette. I think it uses the modem to generate the sounds for the cassette, but I could be wrong.

The OS does have a few bugs, where if a program does something bad (not using PEEK and POKE, but pure basic), or is too big to tokenize, it crashes and erases all memory. That makes writing big programs very exciting.

The OS also isn't Y2K compatible, with this year being "1908".

>20 hours, on 4 AA batteries. No proprietary battery.

Do not underestimate the impact of this, on its popularity.
One big reason the Model 100 was so popular among journalists was
the extremely good (even for now) battery life, together with the
fact that the AA battery is something that you'd be able to get in
even some very remote places.

Re:Still have one. (1)

jmorris42 (1458) | more than 6 years ago | (#23640943)

Emphasize that it IS a Model 100, add links to confirm for the sceptical, and you should be able to move the machine at a profit. There is a resurgence in interest in the things.

What I'd liek to see is an updated version. Keep the idea but use modern semiconductors to give it a useful storage capacity, a little more CPU power and a better display. But DO keep both Windows AND probably Linux off of it to keep the best attribute, instant boot and AA batteries.

More than a "Word processor" less than a computer. Palm OS would be a perfect fit.

I had the same (my dad found it in a cupboard at his work at some point in the mid-nineties, and nobody either knew what it was or wanted it) - except the bloody thing died a few years ago. All it would do was display crap on the screen. I'm wondering if using a different, possibly-wrong-spec mains charger may have killed it.

It was great fun to mess round with when it did work, of course - I wrote various games (enhanced with the extended-character-set editor program) and generally had good fun with it. This was despite having access to way more powerful computers at the time...

The aim was to use it to construct some sort of robot, but I never got round to that. Using some sort of microcontroller effort could be a bit more sensible!

The Model 100 was a MAINSTAY of journalists at the time; since it ran for many hours on AA batteries which you could get anywhere, even in small towns in foreign countries, and it had a built-in modem and a very portable acoustic coupler that would work with any phone you could find. I bet the majority of remote print reporting for several years was typed in the field on a Model 100.

my Dad, a sportswriter, used to use a Model 100, and later Model 200 (bigger screen) to cover the Red Sox - he'd upload to the newspaper via the built-in 300 baud modem - those dreaded 'cups' for connecting to the phone didn't work too well when there was a lot of crowd noise but many phones at the time (early 80's) still were hardwired into the wall so you couldn't use the modular plug...i wrote a program for him in BASIC and Z-80 (i think?) machine code to compute the length of stories in newspaper column inches...i think he still has both machines - he used to carry the Model 200 along as a backup even after he got a 'modern' laptop...

Mine was stolen 5 years ago :( (1)

everphilski (877346) | more than 6 years ago | (#23640917)

Mine was stolen in an airport 5 years ago, sadly. I got it at a flea market for ~$3. It was fun to play with although I didn't use it seriously in college by any means.

Damn thieves! Went on eBay to look for a replacement and it was too expensive for me at the time.

I may have tossed mine, but if I still have it, and you have a need/desire you are welcome to it for the cost of shipping. (not an open offer, just the guy that had his stolen)

After these were discontinued, I sold 100 of these in a week. I was working at Radio Shack, and a company used them as portable serial terminals (w/ custom roms), bought every one of them in the District.

eMate batteries (2, Informative)

cangrande (199946) | more than 6 years ago | (#23640927)

While the eMate did use rechargable AA's, they were soldered together in a little heatshrink pack. So while they are a common size, it's not like you could pop them out and stick more in easily. Still, the battery pack is much easier to rebuild than something like a Powerbook battery from the same era, which often had 4/5 AA's soldered together with various safety components inside a sealed hard plastic case that was impossible to get apart and back together without some major hassles.

The Newton 2000 and 2100, on the other hand, had an optional removable battery pack that took standard AA's.

Those Newtons are remarkable machines and are amazingly useful for being more ten years old now.

Too bad they got discontinued, but the form factor of the eMate was the inspiration for the original clamshell iBooks.

I worked at Denning Mobile Robotics, and we had a bunch of them. They had a printer port, modem, and RS232.

We used them as portable RS232 terminals!! They were cheaper than Wyse terminals and far more portable. They were awesome devices. I often wonder why simple devices can't be created to do a job efficiently and reliably. I guess, with no stable computing standards, they would become obsolete too quickly.

The EeePC was close, but now that it has gone Windows, that device is on the upgrade treadmill as well.

I've been going on about this for years.

I want a note book with 40hr batter life. In days of yore I used a psion with a full keyboard and small LCD. Great battery life.

I have all the components except I need a screen. I'm looking for a either a 1024x768 or 80x24/25 character lcd. B+W is OK. It must have low power drain. Preferrably 14" at least. Where do I find such a beast?

I would have a low power CPU (arm), 4GB SSD, 1GB RAM, screen, clicky keyboard. All bashed into a cutom CNC cut case. Running off 4 C or D cells.

Currently I have an emate but it's days are numbered.

Not a laptop (2, Insightful)

Reality Master 101 (179095) | more than 6 years ago | (#23641159)

What wouldn't you give for a laptop that starts instantly, weighs 3 pounds and gets 20 hours of battery life?

I'd give a lot for that, but this wasn't it. This is more accurately described as a PDA that fits on your lap. What it did, it did well (for the time), but it was very limited. And modern PDAs get a lot more than 20 hours of battery life.

In other words, if you want a modern Model 100, get a PDA with one of those fold-up keyboards and go to town. Instant-on, long battery life, and destroys the Model 100 in usefulness.

Re:Not a laptop (1)

aduthie (530266) | more than 6 years ago | (#23641515)

I think you're supposed to make an argument here.

It's not a PDA because: It lacks a calendar (although you could write one for it). It lacks a contact database (although you could write one for it). You can write software for it without using another computer. It has a full-size keyboard. It doesn't fit in your pocket, even if you get a Steve Jobs special shirt with extra-large pocket.

So, why is it not a laptop? It did most of what any contemporary computer did at that time, and it fit on your lap comfortably. If someone built a laptop today that was lightweight and consumed very little power, but it was only as good as a 5-year-old computer, would you say it's not a laptop? Because that's basically what Tandy accomplished with the Model 100. (Actually it was probably more like 1-2 years behind state of the art personal computers of the day.)

Or maybe you're hung up because you think the article is talking about this being a replacement for modern laptops -- that would be a very ludicrous thing for anyone to suggest, but I suppose we've gotten crazier articles than that before.

modern PDAs just getting worse (1)

flahwho (1243110) | more than 6 years ago | (#23641571)

I've used many, many PDA's for over 10 years now, starting with a timex @ ~200k then on to a Palm IIIx(e), and eventually a Windows Mobile device and a Blackberry, too. What are you talking about battery life being better than 20 hours on modern PDA's?? I can say by experiences with all of the devices I've used (I used to sell them via retail, too and most of the other varieties are the same) that battery life of modern PDA's are much much less than 20 hours. This is primarily fueled by the need to make them smaller, and (you say useful, I say) bloated with features. Stronger processors, more storage, quicker storage access, beautiful backlit color screens, rich audio, network connectivity and multiple I/Os coupled with TEEENNY TINY batteries! I get about 2.5 hours of Pocket Word with backlight on low and nothing else running. How's that for progress?

HP 200LX palmtop (1)

scsirob (246572) | more than 6 years ago | (#23641181)

I still use a trusty old HP 200LX, which sports a graphics shell, MS-DOS, 2MB RAM which serves part as disk, and it too runs on AA batteries.

Alphasmart Dana (1)

Rogue Haggis Landing (1230830) | more than 6 years ago | (#23641197)

The closest current machine is probably the Alphasmart Dana [alphasmart.com] , with a small boxy monochrome display and the same nearly-flat form-factor. The Dana isn't quite instant on, but it's close, and it really does get ~20 hours on a battery charge. It's also used mostly by people wanting mainly a word processing device, but it does run the Palm OS. It's also almost all keyboard, with a really nice big Qwerty setup. It would also be a great reporter's machine.

My older Alphasmart 2000 was just a typing machine, but as such it was amazing. It got, I don't know, hundreds and hundreds of hours of battery life from 3 AAs. I was always shocked when the batteries died, once every eight or ten months.

Best. eBay Acquisition. Ever. (1)

phillymjs (234426) | more than 6 years ago | (#23641229)

I have one of these as part of my "classic computer" collection, and it was the best eBay find I ever got. For something like a hundred bucks I got a Model 100 in near mint condition, with a faux-leather carrying case that was in such good condition it still had the cardboard insert from the packaging in it, a boxed cassette recorder, some software on cassette (remember the good old days when software came with a leather-bound binder containing printed instructions?), all the hardware and software manuals, and a few other items.

Everything is in simply amazing condition for its age, and works great except for the Y2K issue (for which I understand the Model 100 users groups have a fix).

I have the 102 and love it (1)

noidentity (188756) | more than 6 years ago | (#23641279)

I got the Model 102 about 15 years ago and have gotten lots of use out of it. At first, I used it for BASIC programming (all I knew at the time). Later, I wrote several assemblers in BASIC and learned 8085 machine coding with it. I figured out how to do graphics much faster than the built-in firmware does, allowing full-screen scrolling graphics, and lightning-fast text scrolling using the LCD driver's built-in line scrolling commands. This was also my introduction to interfacing hardware. I hooked many things to it, like a sound chip, NES, and later used it as general-purpose I/O for programming a PIC and NES and SNES battery RAM. At some point I also wrote an emulator so I could run my old BASIC programs on my PC. I had even wired up 32K of RAM that could replace the ROM, allowing me to change the font used in the firmware. I still have it on my workbench, connected via RS-232 to my PC.

If you write for a living (3, Interesting)

jalefkowit (101585) | more than 6 years ago | (#23641299)

... the Model 100 is kinda the definition of the perfect portable:

  • Insane battery life on bog-standard AA batteries you can buy in any airport gift shop
  • Full size keyboard for easy typing
  • Screen you can read in sunlight
  • Case tough enough to take a serious beating without a flinch

Sure, it doesn't have the bells and whistles the kids are into like "color" or "graphics", but in a portable for writers none of that is really important -- which is why many journalists held on to their Model 100s long after they became ludicrously obsolete.

With the demise of products like the Psion Series 5 [wikipedia.org] (another writer's portable), the niche that the Model 100 pioneered has basically been abandoned; the only thing close to it today is the EEE PC, which would be an ideal spiritual successor to the hardy 100 if the keyboard wasn't so danged small...

Psion Series 3a (1)

lobiusmoop (305328) | more than 6 years ago | (#23641321)

This reminds me of the Psion Series 3a [wikipedia.org] palmtop, which is almost 15 years old now.

  It had a great usable keyboard for its size (similar to a glasses case) and a big clear greyscale 480x160 screen.
  In terms of runtime, it would run for around 20 hours on a pair of AA's, with negliable standby power, ct1620 button-cell memory backup and instant-on giving literaly weeks of reliable operation between battery changes.
  It ran rock-solid custom-made PDA software (agenda, word processor, timezons, the usual stuff), and included a programming language/editor/parser for coding.
  Amazingly for its time, you could even surf the internet on it (albeit slowly) since a complete TCP stack and webbrowser were available for the later versions, connecting via the serial port on it. I used to run a usable full 80x24 terminal emulator connection over a 9600bps cellphone link on my one - oldschool pocket internet before the days of wifi.

Anonymous Coward | more than 6 years ago | (#23641355)

Bought one new with a coupon I had gotten from AT&T. Used the computer for memo-writing and spreadsheets for about four years (including pricing out several real estate deals). Unit had the best keyboard feel of any computer I've ever used. There even was a magazine (Portable 100) devoted to the unit, with ads for prop-up feet, plexiglass covers, disk drives, memory, software, etc.

GottliebPins (1113707) | more than 6 years ago | (#23641359)

My friend had a Model 100 and I was so jealous. That thing rocked! But I still have my TRS-80 PC-2 pocket computer. It's so easy to use. It's better than a calculator. You can type out entire formulas then if you make a mistake you can hit the back button and see the whole formula and fix whatever you did wrong. I use it every year come tax time. For such a small display you can address every pixel if you want to draw something or make a simple game and it has a speaker you can play music on. I also have the cassette/printer interface. The printer isn't a dot matrix but pen plotter. That was cool to watch it print reports or draw graphs. The paper goes up and down and the pens go side to side. That memory on it lasts for weeks on 4 AA batteries. Sometimes simple is better.

freeweed (309734) | more than 6 years ago | (#23641395)

Durable as all hell, power lasts a long time (and spare batteries easy to carry), and a good old fashioned serial interface.

And yes, I've been trying to pilfer one ever since I discovered that they were still in use :)

pdawson (89236) | more than 6 years ago | (#23641493)

The first M100's came with a whopping 8k of RAM/Storage, not 24k. I know, I have one. Used it all through High School for taking notes in class (can't write fast enough), and again through college. Just plug in the serial cable and upload to PC at the end of the day. Although by college I'd upgraded it to 32k via the wonderful Club100 site that still sells parts/addons/programs for it (http://www.club100.org).

It also gave me my start in programming via hand-keying games from a book into it, and learning how to adapt those programs to fit into 8k RAM I was stuck with then.

I did a little hack so that it would charge ni-cads from the ac adaptor (not a standard feature). I have the floppy drive, bar code reader, modem cups, etc... It had a very well integrated operating system. one of the better things microsoft has done IMHO.
