PIDP11 (and maybe PIDP8) notes

how to get back your session with PIDP11 installed

any time a session is connected it is connected to a screen session running the switch gizmo on PIDP11

normal screen console input seems to work, so <ctl><a> <ctl><d> gets you detached from the session.

structure

the engine for this is a simh generated to accept input from the console monitor (above) which reads the gpio and sends command to the simh emulator.

A controlling client for simh is running separately, and may be connected to.  There seems to be a session running as a demon as well

on the version I'm running:

#cd /opt/pidp11/src/02.3_simh/4.x+realcons/bin-rpi

#./pdp11_realcons

this will get a simh> prompt.  Not sure what's included here.

selecting boot and OS images

There is a prompt on the Screen session indicating how to select a boot OS configuration.  I'm currently without hardware, and there seems to be no response to console, so cannot select and run the emulation as of yet.
