I have a new (old stock) Lexmark Model M13 that works perfectly, all rivets intact. The only issue with it is the cable, which is dried out, cracked, and frayed. Please see https://imgur.com/a/jYPX73C for photos. The cable terminates in a 5-pin DIN for the keyboard and a DB9 for the mouse. I'm looking for suggestions on how best to address the aging cable. As I see it, my options are:
∙ Do nothing. It works.
∙ Use electrical tape to secure the weak spots.
∙ Use mesh tubing (suggested by the good folks at ClickyKeyboards.com, and I have ordered this): https://is.gd/Mu6zd1
∙ Use plastic electrical tubing: https://is.gd/gGadoG
∙ Use heat-shrink electrical tubing, suggested by a friend: https://is.gd/kAkRP6
∙ Use a cable organizer: https://is.gd/Ms7e2G
∙ See if Unicomp can repair it. I asked them via their support portal, they said no. But someone told me to call them and I might get a different answer, so that's the plan for Monday.
∙ Babysit eBay and watch for a replacement cable. Unlikely, I think.
∙ Babysit eBay and find a cheap M13 and use it for parts. Unlikely, though, as I'm told this cable problem is common with the M13.
∙ Buy an SDL cable and retrofit it (is this even possible?): https://is.gd/dvwGMV
Looking forward to your suggestions and advice.
