Here are two RL02 disk images containing a bootable Ultrix-3.1 installation,
from Bill Gunshannon (bill@cs.scranton.edu). He writes:
Install root.dsk as RL0 and user1.dsk as RL1 and boot RL0.
I built the disk images on a MicroPDP-11/23. Configuration:
CPU 11/23+
Memory 3072K
2 RL02 disks
1 TS11 tape
Apparently, this means more to the Ultrix than to something like
RT11. Using the Supnik emulator, I was unable to build a kernel
and even vi core dumps. But then, I am not really sure just what
the Supnik emulator is emulating. Could it perhaps be emulating
a UNIBUS box and the fact that I do not have support for the map
be a problem?? We'll see eventually, I'm sure.
I tried the demo version of E11 but it lacks sufficient memory
for this to do anything. No vi (just says :too big"), no sysgen
(just hangs). I still haven't been able to get into the Begemot
site, so I don't know if it will work with their emulator or not.
[ I have got these images to work with Bob Supnik's 2.3d simulator
using this configuration file:
set cpu 18b
att rl0 /usr/tmp/root.dsk
att rl1 /usr/tmp/user1.dsk
boot rl
