Hello. I've been wondering how to get a little extra memory for my
Macintosh Plus (needed in these days of Hypercard and Multifinder).
I was wondering if the normal brute-force method could be used;
Just solder 1M memory chips on top of the existing one (piggyback)
and attach CS (chip-select) and whatever else is needed from the
adressbus to select the appropiate chip. I haven't really checked
out the memorychips but maybe an inverter is needed for some signals.
If I'm correctly informed there are 22 bit defining the adress on
a MC68000, making it possible to have 4M of memory.
*If* this is possibly, would programs take advantage of it?
Well, maybe this is one of the most stupid questions asked to USENET
since it all began and if so - please forgive my ignorance...
