Wozniak's Original System Description of the Apple ][

CowboyRobot writes "Opening with the line, "To me, a personal computer should be small, reliable, convenient to use and inexpensive." Stephen Wozniak gave his system description of the Apple-II in the May, 1977 issue of BYTE.
It's instructive to read what was worth bragging about back then, such as integral graphics, "A key part of the Apple-II design is an integral video display generator which diectly accesses the system's programmable memory. Screen formatting and cursor controls are realized in my design in the form of about 200 bytes of read only memory."
And it shows what the limitations were in those days, "While writing Apple BASIC, I ran into the problem of manipulating the 16 bit pointer data and its arithmetic in an 8 bit machine.
My solution to this problem of handling 16 bit data, notably pointers, with an 8 bit microprocessor was to implement a nonexistent 16 bit processor in software, interpreter fashion.""
