Recommendations for IMSAI-compatible RAM cards?

Depends on how "vintage" you want to be and the speed of your CPU.
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.
