- Now someone might shoot me, but I'm certain that's wrong.
-
- The Model II used a Z-80. It ran TRS-DOS or CP/M.
-
- The Model 12 used a Z-80 and could be upgraded to include a Model 16-style
- 68000, giving (some people felt) a better Model 16 than the Model 16. It
- ran TRS-DOS in its Z-80 configuration and XENIX in the 68000 setup.
-
- The Model 16 had a 68000 as a primary CPU (hence the name "Model _16_" --
- it was a big deal to have a 16-bit CPU) but used a Z-80 as an I/O manager.
- The Model 16 ran XENIX.
-
- I'm not sure about the Model 6000. It ran XENIX, but I don't remember
- whether it used a 68000. (I think I remember Tandy promoting a 286 Xenix
- system for business, but I don't remember whether that was the 6000 or
- just a box in the 1000/2000 line.)
-
- All four were built for business use. They were using 5.25" hard drives
- by the time of the 6000. The Model II used 8" floppies, though, which was
- a sign of its business orientation. (5.25" floppies were perceived as being
- too unreliable and low-capacity for "serious use".)
