Looking again at one board I have...
There's one design bit that has me scratching my head.
There's a 100-ohm resistor smack dab in the middle of the reset line.
I would like to see if the brain trust can give me any insight as to why...
On one side of the resistor, I have one logic gate (input end), the CPU (similar to MC6801), and the connection to the deadman circuit on another board.
On the other side of the resistor is the MC6840 timer and MC6821 PIA.
