You're probably meaning the Belgian designed DAI computer that was developed for TI initially but was then refused in favor of the TI-99/4. From a corporate point of view it made sense as the DAI was architected around a Intel 8080A. TI-99/4 had the advantage of using much more exclusive TI parts (CPU, Video, sound, I/O, GROM, etc.).
It's a pity that the DAI then could not gain market shares as it was a very interesting and capable computer. It had graphic capabilities that only later 16 bit computer could reach (Amiga, ST), had a semi-compiled BASIC that was fast, even on the quite slow 2MHz 8080, it could use an arithmetic co-processor (AMD 9511), it also had genlock which allowed to mix TV signals with its graphics (long before Amiga), etc.
