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)
