Woz: By the time the Printer card was done with it's 256 byte ROM I may still have been coding by hand or we might have gotten our first assembler. It's unusual to this day that you plugged in a printer and it attached itself to the op-sys by means of a driver in ROM on the printer card. True plug'n play. Possible to this day but rarely done (I've heard of some Newton exception). The ROM op-sys of the Apple II could direct output and input to any of 7 slots. Mass media was read and write an entire cassette file at once. The floppy brought a very tight hardware design, coupled very tightly to the lowest level access subroutines which I wrote without an assembler. Randy Wiggington wrote the "Read Write Tractor Sector" routines, a step higher. Randy and I began a full op-sys but we farmed it out to Shepardson associates. Needless to say, none of that was done by hand! By: Jason Aubrey Wells <email@example.com> Related FAQs Resources: R001a2ad.htm (html text of ad) R003ADGPIC.GIF (GIF picture of ad)
