Rumor has it that coco at yourdvd.net may have mentioned these words:

Only the 8 or 9 chip 256K Simms (the 9th chip is parity, which is ignored) 
will work on a CoCo - Mark already educamated me on that fact in the past. 
It all has to do with DRAM timing issues, and the 1Mbit chips just aren't 
refreshed the same as the 256kbit chips.

I have 80 1Meg 9-chip 30-pin Simms available from an old DEC 3-processor 
486 server, it rather sucks that I can't use any of them for any of my CoCo 
(or other classic) equipment. I wish I had enough knowledge to make 'em 
into a nice 80Meg Solid State Drive ... IMHO that would be kewl beyond belief!
