Card by card I applied power and was able to make it through the general troubleshooting steps without issues. When I apply power to the unit the red Power LED lights and the remaining lights stay dark. Depressing the RUN UTILITY button causes the RUN indicator to light momentarily. If the system is attached to a terminal (in my case a Teletype), depressing the RUN UTILITY button would also cause the system to bootstrap. Striking either the CR or LF key, assuming everything is ok, will cause the system to send an asterisk character to the printer. From the asterisk prompt one can enter U2 monitor commands.
NEXT - Attach to a Teletype
On the Microkit the pins are:
4 (grey) keyboard in (TTY TS 7)
8 (black) keyboard out (TTY TS 6)
3 (orange) printer in (TTY TS 4)
7 (white) printer out. (TTY TS 3)
RESULTS - Current loop is established and the system resets properly. When I run the RUN UTILITY and strike LF or CR on the Teletype nothing happens. The keystroke is not frozen however, it appears to be transmitting, but it appears that nothing is being sent.
NEXT: Put an oscilloscope on the Terminal module, see what's happening.
