Hi Jim,
You are probably missing a driver. Finding one may not be easy. Also did you format the card as DOS or LIF? See
and
Alternatively there was a program called Memory Card Explorer (MCE) that reads just about any card. Unfortunatly the company that wrote it (ELAN) have gone out of business. I think there is a copy of it in the 8924 group file section. I see you are already on that group.
I do have some SRAM cards. If you are interested in one contact me off-list.
