I have another question related to geos. The 1764 RAM Expander, is it just
memory chips on a board? Or is it more complicated than that?

What I am really driving at is: can I build one of these puppies at home? 

I remember in the old VIC 20 days, I built up a board that had additional
memory that when populated gave me around 35k (3K +16K +16K). I also built an
expansion board that allowed me to have 4 or 5 of these memory boards, plus
other cartridges all plugged in at once, and then I could chose memory sizein 
blocks of 8k or cartridges.

Anyway, a board I can make (no wirewrap here!), But is it just a matter of
putting more chips on the expansion bus?

Any pointers would be appreciated.


Thanks,

Logden
