Most PETs (all non-SK, I think) and most C64 IEEE488 interface cartridges use 24 pin card edge connectors for the cable. They look like the userport, but the coding is different so you can't plug the cable onto the wrong port. I recently built one of those myself, and the connections are straight through as well: Connect pins 1 to 12 of the Centronics plug to pins 1 to 12 of the Userport plug and pins 13 to 24 (Centronics) to pins A to N (Userport). > BTW, 24-pin Centronics connectors are not so rare as I thought.

Of course I agree that 24 pin Centronics connectors are readily available, but they are all equipped with the printer port like locking mechanism. The IEEE488 type with the locking screws is just not available for do-it-yourself, they seem to prefer to keep this market for high-priced lab equipment. No wonder Commodore quit using this interface for their homecomputers. Nicolas - This message was sent through the cbm-hackers mailing list.
