I am beginning to write a simulator for a "microcomputer", it will
curses (terminal) front panel. it will be a 12 bit machine. You will be
issue commands to the simulator without stopping the program (for
virtual paper tapes, printing to files etc)
Shown on the front panel will be a switch register, an Accumulator and
program counter (all 12 bit) a "running" light and a Overflow light.
Insert = sw -> pc home = sim command Pgup = examine
([pc] -> sw
delete = (deposit) sw ->[pc] end = halt pgdn = run
Obviously a 12 bit computer suggests a PDP-8, but the function keys are
to be the "bit flip" front panel keys and they are grouped in three
four. I am not against a PDP-8 but it's instruction set is better
in octal right?
Were there any other 12 bit computers? preferably with Hex friendly
Operational choices - should examine increment PC?, should deposit?
I am open to other meanings of the operation keys... they are arranged
as above on
The program will be written in C.
