Warren,
I've been checking out your vtserver program. It's a great idea
and it's been fun to play with. I'm bringing up a /34 and have been
collecting parts for it for a few months. I've got it set up with
a few RL02's on it. Few questions for you:
Do you know of anyone that has used it on a /34? I've punched in the
bootstrap and ran it. It loads the boot file from my Linux system.
It appears to call it but it halts somewhere in the 70000-70040 region.
Nothing comes up on the console. Looks like the memory is over written
with the same values over and over again in this area. Any thoughts?
I'm working on getting a source license from SCO. I'd love to hack on
this with you if you are interested in any help.
Sorry for the delay Kirk. It could be that the V7 bootstrap expects
split I/D, or a different I/O mapping then what's provided on the /34.
I'll punt this to the PUPS mailing list. I have a suspicion that
you won't be able to install V7, but you should be able to install V6
or 2.9BSD instead.
Cheers,
Warren

Hi -
From: Wilko Bulte <wilko(a)yedi.iaf.nl>
I will be doing some more research on this when I get home from
work tonight.
I once had Ultrix-11 3.1 running on a dual RK05 11/34.
What I'd call a
very minimal system ;-) But it ran
That is because DEC put the extra effort into supporting non-split I/D
machines. The "stock" V7 really wanted a 11/70. In fact there was a
chapter in the back of one of the manuals/books detailing what it took
to get V7 running on an 11/40 (it was a non-trivial project).
Several things conspire against V7 and later on 11/34 (or 35, 40, 60,
etc). The two most notable ones are the limited address space,
everything (drivers, data structures, general kernel code) must fit
in 56kb instead of 120kb - (8kb reserved for the I/O page) and lack
of instruction restart on MMU faults.
I'll take a look at the V7 layout later but my memory is that it
wanted an 11/70.
