Running Unix v5 in SIMH

Version 5 only exists as an rk05 disk image, so this is pretty simple to get running.

First you'll need the disk image, it's in any TUHS mirror, and a direct link to the file here.

boot.ini

set cpu 11/45
att rk0 v5root
boot rk0

Then boot it up something like this:

PDP-11 simulator V3.8-1
Disabling XQ
@unix

;login: root
#

You do have to tell the bootloader to boot the unix kernel.. and there is no password for the root user.
