Has anyone ever seen one of these?

It's a credit card sized memory device made by Epson.
Allegedly stored anywhere from 16 - 128K per card. Used some sort of
backup battery for the memory. I don't believe this was flash.
No, I am pretty sure it was battery-backed RAM
Apparently Epson OEM'd them to various companies
for use in various
devices, presumably including laptops.
I seem to rememebr (and hey. it's about 15 years ago,...) that you could
modify some Epson RAM card to work in the HP48SX calculator. I think it
was a mod to the low-voltage detection circuitry. I wouldn't be suprised
if the 'real' HP cards were OEMed by Epson...
