Tandy 6000 HD

This system was used to run an optometrist's practice, and has both the internal 15MB hard drive and an external 15MB slave. It also has the optional 3-port serial board installed. Neither the internal or external hard drives worked, but a replacement controller board cured that. The keyboard needs to be overhauled - most of the foam pads have disintegrated. I learned Xenix on a machine like this, back in 1985, and co-authored a multiuser BBS for it. I found the original code from 1986, and got it running again on this system.
