Vintage computing - restoring a Texas Instruments professional computer (TIPC)
This is the Texas Instruments Professional Computer, the portable version (a better term would be "luggable"). They are very hard to find nowadays, a rare piece of history. There was also a TIPC desk top model with which it was 100% compatible, and with which it shares much of the hardware. The TIPC competed with the IBM XT of the days. It was much better built and had superior color graphics capabilities over the IBM. However, it was only marginally compatible with the IBM, and also much more expensive. It therefore never became popular. The whole project was an engineering masterpiece, but a marketing disaster. TI followed up with the "business pro", a machine that was both IBM and TI compatible. But it was too little too late; another marketing failure. When Compac started to eat their lunch (a company founded by ex-TI-ers who were done with all TI's marketing blunders), Texas Instruments exited the PC business.
