it doesn't have to be entirely of 7400s or the like,
just a design where no *exotic* programming is
required. I just wanted an idea. A microcontroller,
and whatever else is fine.

to make one of these in discrete logic:
(if you don't feel like looking, it's an Apple II
IDE/Cflash controller)
Just a rough chip count.
It looks like there are a couple PLAs, some discrete
logic, a
microcontroller of some sort, and an EPROM.
Frankly, I don't think doing
discrete logic for something like this is worth the
trouble. The card
itself seems sufficiently low-tech already.
