Do you know if the TI 99/4A board has over voltage protection on the 5v input on the motherboard? Example if power supply feeds more than 5v instead of 5V on the motherboard due to fault in the Power Supply, would the TI 99 4A motherboard regulate it (burn a fuse etc...) or will it leave all the voltage to fall on the Chips (VCC) ? Thanks Well done on your work.
