The "Crd" request should not have occurred with such a short program. This error points to (at least) the first 28 bits from the card are not being read properly. This is the STATUS information about the card program.

When I get time, I am going to update the code for the 65, 67 (and 97) CPU replacement boards so that they can all read raw data from the cards and provide a screen dump of the information on a PC. That way users will be able to see where the errors are. Whether that actually helps finding the fault or not I don't know.

cheers

Tony
