TMS9900 CPU

Studying the TMS9900 processor of the 70s and 80s, I have learned that it was capable of Multi-user preemptive multiprocessing. This is very sad that I'm not aware of this every being utilized with the TI-99/4A computer. This can be done with workplace register pointers that can be handled by the CPU, but stored in memory.





Because we are using pointer, this can be changed on the fly. Because of the interrupt processes, we can go back and forth between tasks.
