If you use Johnny's RSX-11M-Plus at /opt/pidp11/systems/rsx11bq
then look into file boot.ini
In the block:
-----------
; under SimH 4, "throttling" results in a disturbed "idle pattern"
;set nothrottle
set noidle
set throttle 50%
;set console telnet=10000
sho cpu
-----------
uncomment (remove the ";") the line ;set console telnet=10000
and restart SimHH and your PiDP
This should work.
Also, if you want to access the Ethernet out of RSX (DECnet or just IP), then you need to run the emulation with root privileges for now, or else you will not be able to connect to the Linux eth0.
I may have time later this week to find the right Capability settings, and in particular the right place to attach them, to make this problem going away. (The Capability settings currently in the kit are not effective for this, also I cannot speak for the other PDP operating systems besides RSX-11M-Plus at this time, but they are likely affected as well).
