I know the model 16 had a 68k, but it just seems bizarre that a version of Unix ran on a TRS-80.

- leejoramo 6y agoThe earlier Model II was the first TSR-80 with Xenix.
- housel 6y agoNo, the Model II had only a 4MHz Z-80. The Model 16 (and later the Model 6000) had a 68k-series coprocessor, and Xenix ran in that (using the Z-80 for I/O).
- jandrese 6y agoIt's not so crazy when you consider the specs of the machines Unix was developed on. A PDP-11/20 comes with 24k of memory (16k 18bit words) and 500k of drive space and was shared between an entire department full of people. The reason Unix exists is because they couldn't afford a machine big enough to run Multics.
- dboreham 6y agoAn 11/20 didn't give a great Unix experience though. You needed an 11/45 with a 80MB drive to support multiple users.

- hapless 6y agoThe model 16 was so much bigger and more powerful than the original TRS-80 that it included an entire original TRS-80, whose only job was to operate the keyboard and serial port. Seriously 100x as much CPU power
