GM803 rom-eprom card

This housed four banks of four EPROMS each and a 8k BASIC ROM position. Each of the four EPROM banks could be selected as either 2708 (1k x 8) or 2716 (2k x 8) types.Like the RAM (B) board described elsewhere this board also supported the paging system.

As you can probably see, this particular card has been used in a Nascom system as it holds several Nascom EPROMs and Nascom ROM BASIC.
