Tri-Data Memory Boards

Hi,

   I have some old memory boards that use the EMM SEMI 4200 Chip (the same
as the Altair 16K Static RAM 16-MCS Board uses). They have TRI-DATA etched
into the copper. They also have "MCI 1" in white silk screen on the card.

   They have a strange configuration: 6 Bit colum X 4 Bit row. They also
have an EPROM on board.

   Does any one know where they came from, what they are used for and if
they are worth anything.

   If they are worth something, I would be willing to exchange them for a
fair price. If they aren't worth anything, I'll just scrap them and sell
the memory for use with an Altair.

   At any rate, if anyone knows anything about them, I would appreciate
knowing about them.

                                Thanks,
                                Neil.
