My SE has a PDS expansion card in it.

It is identified as "MoDAM SE Rev B © 1989 MEMORY PLUS"

it also has a sticker on a chip "Monochrome Spark".

Has a 9 pin pug on the expansion port at the back.

Machine has a fairly clean sys 6 with some scanner software on, certainly no drivers.

Anyone know anything about this card, or where to find drivers?
