	The '''Tandy TRS-80 Model II Family''' was a high priced line of TRS-80 and Tandy computers. The were used almost exclusively as business machines. The line started in 1979 with the TRS-80 Model II, the successor in name and processor only to the original TRS-80 Model I.

	There were 3 major versions of TRSDOS available for the systems. Original TRSDOS, roughly based on Model I TRSDOS but with Microsoft Basic integrated into the OS; TRSDOS-II, a DOS designed specifically for the Model II family; TRSDOS-16, which is less of an operating system and more of a system overlay that allowed the execution of 16-bit TRSDOS software on the Model 16 and 16B. Very little software was made for TRSDOS-16. One TRSDOS clone was available, a Model II family compatible LS-DOS. Four or five versions of both CP/M and CP/M were available with the most popular being Pickles & Trout CP/M 2.2. The total game-changing OS available for the Model 16B and Tandy 6000 was Microsoft XENIX, a 16-bit Unix based on System III Unix.		There were 3 major versions of TRSDOS available for the systems.
