I have a POSTcard version 2 for an XT or AT IBM. It uses AWARD software and dated 1988.
I know that it is a long shot but does anyone have the driving instruction for this card.
It has 2 blocks of ten switches so its almost impossible to work out all the test options that its capable of.
In its time it must have been capable of running a complete set of diagnostics for these early machines.
A real boon because even if the board was not socketed it was fairly easy to replace the chips. Not now as so much is surface mounted.
Keeping my fingers crossed
