About the compupro CPU-68K and dynamic memory.

On going through the schematics, I find an output labelled sMEMR,
on pin 47 on the s-100 bus. I believe this is the memory refresh
line you want.

Also, I've been running a CPU-68K with 128K of Intersystems dynamic
memory with no ill effects. However, I am running it at 4MHz until I
get all the bugs chased out of the DC code, etc., and buy faster memory.
