I found a quad width card marked CESI VM816. It appears to be a memory card and has four rows of twelve IC sockets. The first row has 7 TMS4044-20NL ICs (4k x 1 SRAMs) in it and the second row is fully populated with the same ICs. The other rows are empty. There is an 8 position DIP switch as the end of each row of sockets. Does anyone any docs for this card or know anything about it? Joe
