The Tandy TRS-80 Model II Family was an expensive line of Tandy computers. The were used almost exclusively as business machines. The base Model II and its Double-Sided floppy and more expandable brother, the Model 12 had a Zilog Z80A running at 4 Mhz with DMA. They ran both TRSDOS and CP/M. The original follow-up to the Model II was the Model 16 which was a dual processor machine with the Model II's Z80A for I/O processing and backwards compatibility with a 68000 CPU for 16-bit operation and up to 1MB of ram. Unfortunately, the Model 16 was a flop due to lack of 16-bit software, so then the improved Model 16B was released and it was show stopper due to the fact that it was one of the most affordable [Unix] machines on the market running Microsoft XENIX. It was the best selling Unix-based machine in 1984 and could support 3 (or more?) users. The final incarnation in the series was the Tandy 6000 which came with more RAM, a built-in hard drive and a detachable keyboard. These machines, much like the Sun-1 had a custom MMU to run Unix, and also, there is an excellent emulator available for the whole family called trs80gp
Some information can be found:
A huge collection of software and documentation can be found at:
It is recommended that you clone the archive instead of downloading the zip file because it tends to fail otherwise.
The trs80gp emulator is available at: http://48k.ca/trs80gp.html
A couple of tutorials to try: Installing TRSDOS-II 4.4 onto a Model II or 12 System With a Hard Drive and Installing XENIX on a Tandy 6000
