Thanks everyone for all the suggestions and advice. I'll keep my eyes
peeled for some good SRAM cards (a few people on the list have offered,
so I'm off to a good start!).
Thanks again!

Depends on how "vintage" you want to be and

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.
Cheers,
