It just displays "PROGRAM" when I try to run the card. No clue how to burn a fresh image to it!

EDIT: Correction, it's an EPROM, not EEPROM. There's a small sticker on the back to expose the chip for blasting it with UV.
Are all the cards like that or was yours a custom one?

There were 32KB (not seen here) and 128KB EPROM cards, sold for VARs, ISVs, etc. to distribute custom apps, written in C w/a custom SDK Sharp provided.

Also, the 770, 870, 871 cards were simply the same as the 707 and 8B03 cards with generic labels, also intended for VARs that preferred to program in BASIC. The ROM within these was identical to the "BASIC Cards", only the labels were different.

It's odd that it faded, unless the cover over the window fell off and over time ambient UV erased some bits, but that's pretty unusual.
