I just got a PET2001-8C with board rev. 320081 for repair. This is the model with 6550 RAMs and 2316 ROMs. Both tape ports on this machine are different from other Commodore machines in two ways: 1. only the lower side of the ports is connected to the tape signals. 2. there are two key notches, so even keyed connectors can be inserted upside down! I have a small problem now, because I sold some video adaptors with a power cable that uses the power pin on the upper side of the connector. This also means that the C2N232 will not work on this board, as it also uses the signals on the upper side. Users must be careful not to insert this device upside down on this board. My own PETs use the older 320008 board assembly, and its tape ports are constructed normally. Does someone own the other static board revisions 320132 and 320137? I'm interested if their tape ports also have the same problem.
