Hi Steve, unfortunately, only a few parts of the set seem to be original commodore. There are labels on the eprom and the user-port connector, that appear to be original. The RS232C connector was missing. The other connectors were reduild ones. The cartridge pcb is a 3rd party one. There is no housing. According to the owner, who was a commodore wholesaler at that time, the diagnostic set was originally build by commodore, but they often were not able to deliver the sets. So he rebuild the sets for other dealers. Christian Am 22.11.2012 17:23, schrieb Steve Gray: > Hi Christian, > This is nice. Thanks for posting! > I'm curious about the cartridge..
