For a couple of years, I used the SSM 8K SRAM boards (64 x 21L02)--
but that was on a 2MHz Z80. Later, I used a 64K DRAM board (Digital
Research: Computers, I think) that used 4116s and worked all right.
What I would not recommend is the early DRAM boards (e.g., the MITS
4K boards). They can be very flakey, even when when they were new.
If in doubt, stick with SRAM--fewer timing issues.
As another poster has noted, the CompuPro boards were good.
Godbout static ram cards work great in my Imsai.
Any cards which uses the 6116 static rams work fine too.
My SOL20 16K dram cards work fine in mine too.
