===== History and Trivia =====

The TM990/189 University Board Microcomputer was designed in 1978 and probably released in early 1979.

Its primary target was University computing courses.

It was sold with a simple assembler & debugger, UNIBUG, and a 500-page textbook titled "Introduction to Microprocessor". The UNIBUG program has not been dumped, and is therefore not available.

TI additionally sold University Basic for the TM990/189. It is a relatively simple Basic interpreter. This program is emulated.
