Not sure if this has already been scanned in, had it on my shelf a while, so today I ran it through the sheet feeder.

Interesting tidbits: The keyboard IDs for Keytronic and Apple made keyboards are different. The COPS controller in both the keyboard and I/O card is identical including the code. Different routines are called for each.

Card IDs can cause the system to auto boot from the a card, including an AppleNet.


This was a good read. I like the detail on the video board's theory of operation, too.
