Tandy 6000 HD
|Tandy 6000 HD from 1985
||Z80A @ 4MHz / 68000 @ 8MHz
||15MB internal, 15MB external
||TRSDOS, CP/M or Xenix
||5 serial, parallel printer, external hard drive
||$5499 for the 6000HD, $159.90 for 512KB RAM upgrade, $199 for
3-port serial board and $1295 for the external 15MB drive
||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
