A bit of an oddity, this one. It was designed by a UK company called Costgold Research and, as yet, I know very little about it. I have been told that about 40 of these were eventually sold - some via Gemini and some direct.
The card holds a 8088 processor with 256k RAM and its own BIOS EPROM. I presume that the larger of the two blue connectors carries a 16-bit bus for connection to other cards. However, if you look closely, there are two holes drilled through the board. One is at the left-hand end of the long connector and the other is to the left side of the bottom vertically-mounted ICs. Were these perhaps fixings for a daughter board?
That is about it. I don't even know what the missing ICs are. Please let me know any further information that you may have about these - I'm sure there are a lot of people who are just as curious about these as I am.
