Hi guys, new SIMH (and Research Unix) user here coming from the future
(Linux), haha. Well, as the mail subject says, I have a problem.
After creating a bootable disk from a virgin Unix v7 distribution tape by
following this guide, http://homepages.thm.de/~hg53/pdp11-unix/, and after
umounting the usr file system and halting the machine, SIMH returns:
HALT instruction, PC: 000002 (HALT)
after running the command:
pdp11 run.conf
and I cannot boot my 87,9 MB 'system.hp' disk.
I thought the problem was on the final line of 'run.conf':
run 2002
But when I use SIMH without .conf files and by manually typing the
following commands:
set cpu 11/45
set cpu 256k
set rp0 rp04
attach rp0 system.hp
boot rp0
I see the same HALT message too.
I'm currently unning SIMH from Debian/Ubuntu package 3.8.1-5build1. Should
I update to a newest one? Or did I make a mistake when creating my bootable
disk?
