   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 :'(  
 
Are the PAL equations known?  I'd be happy to burn a few GALs with
equivalent equations and send them your way for the cost of postage.
