Every Psion collector knows that the parts for Psion 5MX are scarce nowadays. The serial cable is no exception. The only current source is Psionex, but it can cost more than $50 with shipping to US. Too expensive for just a used cable.
Recently I asked about this on Reddit, and a kind user suggested me to look into some PCMCIA dongles, as they seems to have similar connectors. I did that and happily discovered it is possible to make a Psion serial cable out of PCMCIA dongles, at a relatively low cost, and with a good-looking finish. Let me document the process here.
