Hi all,

I have a nice AST Preview I/O card. It's a 8bit card that has MGA/MDA capabilities, a parallel port and there are 2 connectors for external connectors that look like Serial and Game Port.

In addition, there is CR2325 lithium battery, so it seems this card has Clock capabilities too. On top there is an EPROM stamped (c) AST 1986.

Does anybody have some more info on this card? What do the jumpers do and are the external connectors for serial and game?
