It would be a lovely thing to have someone make a few
of these. I've
been looking for a memory expansion board for my IIc+, in the USA, for
months now, with no result. The best way that I have heard to find
boards is to blindly buy IIc and IIc+ units, and hope one is
installed.
If you go this route, I'd love to have one of your main boards...Mine is
fried and looks like one of the PALs. I already xchanged the dedicated ICs
with a //e and found no TTLs fried :'(
