I just took delivery of a replacement five-pin cable so my old one, which came with my '82, isn't much use to me. The cable needs some wiring work I don't feel like taking on, but these don't come up too often and maybe somebody handier with a soldering iron than myself wants to give it a try.
The cable was discussed in this thread:
