I had a TI 99/4A back in the 80s. TI Logo was pretty good (the company had been interested in Logo for some years). The system architecture was really nice, and for the time, the 9900 microprocessor was really elegant. What doomed the system was TI's vision of a closed architecture, with software distributed on cartridges on which TI would make a rip-roaring profit. When I read about this vision, I put my system up for sale, and sold it a few days before TI announced they were getting out of the “home computer” market. I've never known much about TI's internal workings, but I've always imagined that the company, at least at that time, had excellent engineers and really clueless management.
