WOW! Just finished reading this entire thread. I used the TI-99/4A UCSD PASCAL with P-CODE card in the late 80's when I was in college. I think I was the only student using the TI at University of Iowa in the 80's. The Terminal Emulator did great connecting to main frames so I could upload my code, test it on the University's systems, then print my code on greenbar sheets and turn it in to the TA.
I'm buying a fairly complete system with a P-CODE card, so going to start looking for the Editor, Compiler and Linker software online.
(If anyone has a complete set of the original manuals and disks, let me know.)
Thanks! Ron
