	I'm not familiar with the memory, but beware that the Compupro boards I'm
	familiar with do not generate refresh for dynamic memory, which is why
	all Compupro memory boards are static.

Why would you care about generating refresh signal from the CPU ( I assumed
this is what you meant, please correct me if I am wrong ) ?
Most dynamic memory boards (IEEE-696 compatible ) generate refresh internally.
I have no problem running dynamic memory boards on my S-100 system.
But you do have to be careful about DMA accesses when using company X's
CPU with company Y's memory board and company Z's disk controller.  Very
often, the timings are so tight that only boards from the same company
work correctly.
