I posted yesterday about my attempt to weld a IBM PC keyboard to my Compaq model 1 - the 'luggable'.
Well, it did not work, even though I saw clock and data on both Compaq and IBM keyboards that looked the same. I did not dig into the decoding, but somehow they are different. OK so I already cut into the PC keyboard, a BTC 5100. I let my son play with it and a screwdriver, and as he gets it apart, I see capacitive foam pads inside. Well guess what, they are the same size and fit for the Compaq Keytronics keyboard! I popped out all the pads and transplanted them, you push them in and snap the plastic disk in the guides with an exacto, and they work perfectly. I think a lot of these early keyboards before the switch to elastomeric rubber have these foam pads, and they are a standard size. If you are stuck with a Tandy, Lisa, Sun with keyboard foam rot, take a look in you junk bin for a IBM PC compatible keyboard, it worked for me. Randy
