Hi Jim,

Here's Jayseon's post in Facebook (it was a while ago):

I've been working on the programmable logic for the 2 meg ram upgrade 
for the Coco:

"ERROR:Cpld:837 - Insufficient number of macrocells. The design needs at 
least 37 but only 36 left after allocating other resources.
Device 9536XL44PC was disqualified."

*Grumble*

On the plus side, the next largest capacity device is available is a 
drop in replacement for the XC9536XL.


I'm very interested in seeing this happen as I'm sure a lot of other 
folks are.  The other really important item we need as well is some 
replacement mylars for Coco keyobards or perhaps a think circuit board 
(as John Linville  mentioned).  The mylars are delicate and failing.
