48GX Custom ROM Card by Ford?

[Raymond Del Tondo]

Thanks for the pic.

Doesn't look like the EPSON cards I have seen.
The EPSON cards look like the HP cards, with metal slip shutter.
AFAIK there were OTPs, EPROMs, and RAM cards from EPSON.

Another company also made EEPROM (Electrically Erasable Programmable ROM) cards.

Your card reminds me of an OTP card which SMI used for their Surveying software,
with both sides bare metal, without a shutter, and the wider black plastic frame on the grip side end.

Is there somnething visible in the Library menu?
If yes, is there a button named "About" or alike?
