John,

The 512k upgrade board requires 8 bit refresh SIMMs. Even the 3 chip 256k 
SIMMs won't work they have to be 256k x 8 or 9 modules.

If I can't locate some I'll redesign the 512k upgrade to let the SIMM take 
care of the refresh and not the CoCo. Thus a price increase in the 512k 
board cost.

Thanks,

Mark
