OK, this is truly off topic, but as this board has proven to be a fountain of knowledge, no matter how obscure, it's worth a try...

A friend of mine is very keen to locate a reader/writer (or any way to read/write) an old battery-backed SDRAM memory card, originally manufactured by Epson, but also second sourced by Centennial Technologies and Smart Modular Technologies. The cards have not been made since 1998, came in sizes of 32K, 64K and 128K, and were used (apart from Epson systems) in Panasonic word processors and IBM punch card consoles. I am encclosing a couple of pics of the (credit-card-sized) cards.

My friend is working on a vary interesting, computer security-related project that (if my friend is right) might have very interesting implications. All he needs is having a couple of cards read/written, as a one-off thing.

Why is the project interesting? Well, seems pretty well the only remaining major user of the cards is Diebold Systems...
