TI-95 Procalc from 1986

This video is about the TI-95 Procalc, Texas Instrument's powerful keystroke programmable scientific calculator from 1986.

In the video I walk through the calculator's basic usage, ROM libraries and keystroke programming. I also explain how to enter and run TMS7000 assembler routines by disabling system protection mode.
