So, on this Model III I'm working on the following keycaps are missing: 1/! key right shift key Looks like keycaps from a Model III, and possibly a model I would work. Probably a Model IV keycap for 1/! would work, but I think the right shift key would be different between a Model III and Model IV. I also need one of the ALPS switches as the '+' part of the stem is broken off. In addition, on the drive (Texas Peripherals), there is a plastic component that screws onto the aluminum arm with the diskette retaining hub with 2 screws.... it then accepts two plastic pins that connect this piece to the drive door. I am missing on of the plastic pins and the plastic piece is cracking. Anyone have any of these parts kicking around. On a Model III upgraded to a Model IV I have, the ribbon cable to the serial/com board has 'self destructed' as the glue failed, so once removed it could not be reconnected. Interestingly the cable for the floppy controller did not deteriorate ????? Sadly on the upgraded Model III someone converted it to 3 drives, using an original full height drive for the 1st drive (at the bottom), and put 2 HH drives in the top bay. To make room for the eject control on the top drive, the upper case has been notched. It would be nice to find an upper case for a Model III and do away with that notch.... or alternately an empty Model IV case (top and bottom). Thanks to anyone with any TRS-80 'parts vault' that may have these parts available.... It has been a long time since I have touched a Model I/III (last time was probably 1983 :-) ). Looking forward to getting the 3 systems I have up and running (Model I with Expansion, Model III, and a Model III upgraded to a Model IV). Thanks in advance, -- Curt
