Hello to all AF members,
at the end of April after VCFe has passed by i´m starting to reverse engineer the Apple //e Diagnostic Rom Card.
This card was used by dealers and service technicians to make fast diagnostic on Apple //e systems.
It contained a diagnostic programm in Eproms and was able to uncover nearly every problem known by the Apple IIe.
It has never been released to the public and therefor only very few of this cards have been made.....
but it has for sure quite a large value for larger user communities and local user groups or collectors with
larger amount of IIe computers in their collection for assisting their local staff by maintaining the members computers.....
i´ll therefor perform a reverse engineering task on this card and publish the information here in an own thread....
here at first step a view on the top and solderside of the card:
and the bottomside:
