[Simh] Unix SYS III on SIMH

[Jason Stevens]

Well a little more digging around and I cooked up this much... using
an rp06 from 32v, that I had copied in the sysIII kernel.. (tar &
whatnot)  Anyways I thought it was interesting that sash can load 32v
& the sysIII kernel, and the 'stand' directory programs... It would
seem the prior copy I had found was PDP-11 binaries, which was
throwing me off...

So, using the following ini file...
set rp0 rp06
att rp0 rp06.disk
set tti 7b
set tto 7b
load -o sash 0
run 2


I can get this much:

VAX780 simulator V3.8-1

$$ /stand/ls /stand
cat
conflp
dd
du
fsck
fsdb
iltd
ls
od
rp6fmt
rpboot
sash
tapeboot
vrmhead
$$ /stand/sash

$$ /stand/rpboot

$$ /stand/ls
bin
dev
etc
fboot
lib
mnt
stand
sys
tmp
unix
unixhpht
usr
$$ unixhpht

UNIX/3.0.1: unixhpht
real mem  = 8323072
avail mem = 8207872


I'm not sure why it's crashing at the moment, probably because the
root filesystem is 32v's system 7?  Anyways it's some progress, I'd
assume that the VAX can read/write/boot from a PDP-11's rp06 disk?
That'll be my next experiment when I get some time...
