If you are lucky to run ITS on a
- real KA10,
- PiDP-10,
- KL10 with KL-UDGE board, or
- emulator with Panda Display board,
you will have some lights and switches. In addition to the normal functions, ITS has some more:
The memory indicator lights show which job is running. This can be disabled by setting MIPGDS to -1. To control the lights from a user program, use .IOTLSR to enable IOT user mode and write to the lights register with DATAO PI,AC.
On the PDP-6, the memory indicator lights are connected to speakers.
Data switch 0 will make ITS go to NTS DDT. This is very useful to set breakpoints etc, for debugging ITS. Switches can be read from a user program with DATAI APR,AC.
