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.
