Well, that's a start. Have you ever wondered what happened to change
apple's openness? The Apple II+ came with a user manual that included a
complete copy of the sources for the ROMS and an in-depth description of
how to program _everything_. I don't think mac manuals even have pin-outs
for the ports.
Reading some junk, did you know that for a while, Apple built the UniDisk
3.5 for use with IIe's, and that it contained a 65C02 microprocessor in
the drive itself.... Yikes. Nothing like having a drive that runs on a
better processor than your computer....
What controller chip did Apple's II and II+ use (on the card or whatever)?
Ideas?
