The current configuration on my Texas Instruments TI-99/4a is:
There are numerous unique qualities to the TI-99/4a. I guess that the most outstanding of these is that it was one of the first 16-bit microcomputers. The TMS9900 processor is a unique processor in that the registers reside in RAM pointed to by a Workspace Pointer (WP). This makes context switching incredibly easy, but makes the processor exceptionally dependant on sufficiently fast memory. The graphics archtecture has support for a transparent color for use with a Genlock so the machine is at least potentially suitable to being a powerful video titling system. Unfortunaltly I am relatively ignorant of this particular system, and any help with it would be greatly appreciated.
