> How to detect how much memory is actually in a COCO 3 from basic?
Look through the top vents.  A satellite board indicates 512k, No 
satellite board would be 128k.

A coco 1 with very rare exceptions will have a large gray case, the CoCo 
2 will have a smaller CoCo3 sized case.  As to software,m there were 
extremely few differences.
