Watford Electronics Apex Control Card (top)
Watford Electronics Apex Control Card (bottom)
The Apex Control card is an upgrade for the BBC Micro the connectors on the bottom replace the 6502 and 6522 on the BBC circuit board and are in turn put in the corresponding scokets on the board. The board appears to be a RAM/ROM board with sockets for 15 ROMs and 16K of battery back RAM. However I can find no details of the board and I do not know what the 60 pin connect on the back right is for.
