Tandy XENIX Disks

Reminds me of a couple of AT&T 6300's that I used in an exhibit at the Field Museum of Natural History here in Chicago. The keyboards were mounded under 1/2 inch particle board, with just the keypads showing (to run the program). We needed to add an extra instructional label beside the keypad, so the exhibit preparators screened the labels and, to protect them, mounted thin plexiglas over them. To mount the plexi, they drilled 4 holes all the way through the particle board -- and the keyboards that were underneath. Amazingly, neither of the keyboards was destroyed.

There's a plastic post moulded into the bottom case of the machine under the keyboard. If something heavy is dropped onto the keyboard, it will cause this post to hit the PCB with enough force to break tracks. While you have the keyboard apart, examine this area of the PCB very carefully. -tony
