Sorta clich? response but check your local craigslist. They're really not too uncommon
and shouldn't run you too much. IIc may be a bit less common than its big brother but
still not at all rare or out of reach.

Anyone know of a source of apple IIe keyboards???

I did that before posting my request here. I've seen them on the NH or Boston area
Craigslist in the past but there don't seem to be any available at the moment.

If anyone can find a logic board of a IIc (first or second version, mine
is the 5 1/4 FDD type) that works, I'm in! :o)

And I'd like a IIc logic board that is bad!
Or, for that matter, bad IIc+, IIe, or IIgs logic boads, or even good
ones, or just the ASIC chips from them.
The plan is to remove the Apple ASICs and decap and photomicrograph
them. Especially interested in:
IIe: HAL, IOU, MMU
IIc(+): HAL, IOU, MMU, IWM
IIgs: FPI, Mega II, Slotmaker, VGC, IWM, RTC, ADB GLU, ADB
microcontroller, Sound GLU, DOC (Ensonic)

It's a Mitsubishi part with a 6502-compatible core.

I'm pretty sure you can see what those circuits do by looking at the Apple
II (or Plus) motherboards- at least for the IIe. :)

For the IIe, and IIc it is mostly obvious. There are perhaps a few
subtleties, though. But I'm pretty sure that I could program CPLD or
FPGA equivalents that would work fine to replce them.
For the IIgs, there's a lot more going on in some of the ASICs. The
broad functionality is clear, but the details are not.
