  HOPE 11 by Bill Degnan - 07/22/2016 00:25
Friday night - I have simh installed on my raspberry pi, and I am using my laptop to connect via the serial port, two usb to serial cables and a null modem adapter. works well.

root@raspberrypi: CD BIN
root@raspberrypi: ./pdp11
sim> SET CPU 11/40
sim> SET CPU 16K
etc.

To make sure everything was working correctly I set up a PDP 11/05 per this page and loaded BASIC
http://iamvirtual.ca/PDP-11/Basic-11/Basic-11.htm

To exist BASIC - use ctrl+E to return to the sim> prompt.

Next I attempted RT-11 by following the directions here:

http://gunkies.org/wiki/...lling_RT-11_5.3_on_SIMH (Noel's site)

root@raspberrypi: cd /bin
root@raspberrypi: ./pdp11
sim> do inst.ini
...
Overwrite last track? [N] y
etc.
follow directions on Noel's site to set up your PDP 11/23+ environment.

Noel finishes with directions to create a run.ini that you can load and bypass the install steps.

sim> do run.ini

NEXT: Adapt this for a 16K system, to see if one can load and run RT11 5.

  RT 11 v 5.3 needs 32K by Bill Degnan - 07/23/2016 11:24
I altered the run.ini file (pdp 11/23+ 256K RAM) to emulate an 11/20 with 32K instead. The reduced configuration will load RT-11 v5.3. Next I attempted the 11/20 with only 16K RAM. This appears to be too little RAM, simh bombs, I cannot load the operating system.
