TRS-80 Model 6000 Keyboard

Well, just days after my post regarding XENIX for the Tandy 6000, its keyboard seems to have gotten some ideas from Jeff's post on TRS-80 keyboard problems. The 'D' key has taken sick. Every other key on the board works flawlessly. But simply in the course of normal use, the 'D' key has stopped working. I've "fixed" it to the best of my ability, but the problem obviously goes beyond that. Now, that one key in itself wouldn't be so bad, except that in order to get to the login prompt in XENIX, you have to type CTRL-D. Which puts my 6000 in the very large paperweight category at the moment. So my question is - Does anyone have a spare 6000 keyboard lying around, or know where I might go about looking for one? I have enough systems lying around waiting for parts to complete them, and I really don't want this one to join them. Thanks. -- Owen Robertson
