Thanks for the assistance to date!
Actually, I have a second M7800 card installed on the PDP-11/10 machine. I
was having so much difficulty with getting a 20mA terminal (LA36-DP - OEM of
an LA36) to work, I just about disabled the console SLC and reconfigured the
the M7800 to work as the console! I also have M780 spares if I need them.
(If anyone knows anything about the dip switches on the DataSouth Printer
board in the LA-36DP P/n 5120000-1, I would be most grateful!)
As far as memory, there are two 16kw core systems installed on this machine.
I also have lots of paper tapes (mostly diagnostics, but also Fortran
compiler), and 9-track tapes. I am needing to know what I am looking for to
get RT-11 running. What did DEC call their install tapes? eg. Is the
"RT-11 V03B BIN MT9 1/2" tape the boot/install tape?
Is RT-11 the easiest O/S to get installed? I want to get to a point where I
can verify the hardware is all running.
As far as media devices, I have 3 x RK05, 1 x TS03, 2 x RX01, 1 x TU58. I
am trying to decide what will be moved to the PDP-11/10 from the 11/20. The
goal is to have the PDP-11/20 up and running. Getting the PDP-11/10 is just
a step along the way.
Where is this VTServer people had mentioned? I don't recall this item.
Thanks.

I would strongly recommend using TU58.exe on a
host pc to emulate a
serial tape drive on your second serial port (you DO have a second slu?)
On a machine that old? Unlikely. Machines of the era before the DZ-11,
and especially machines that were not destined for timesharing, tended
to have few serial ports, - a console and probably nothing else. It was
a boon that a low-end Qbus machine commonly came with a DLV11J with a
port for the console, a port for a TU58 and two more ports for DECwriters
or machine-to-machine communication or whatever.
It's easy enough to _add_ a second SLU card, (DL-11something), _if_
you have one lying around (which I expect he doesn't).
to boot RT11 off virtual tape so you can poke
around and build a system
from there.
As a place to put RT-11, a virtual TU58 isn't a bad idea. Hopefully
wharever emulator you have can emulate both units - the TU58 is kinda
small, even compared with 8" floppies.
VTserver is really amazingly great, but you may
not have enough ram and
booting RT or XXDP from a slu will give you better diagnostics to assess
your RK05,etc
How much RAM does VTserver require? Older versions of RT-11 (those
contemporary with the 11/10) are usable at aroun 8KW, IIRC. Of course
the full 28KW is nice, especially if you want to run large apps like
ADVENT, but the CUSPS should all run with minimal RAM.

That's handy (and it ends the speculation if you have two SLUs or not ;-)

Nice. That should serve nicely. Wish my 11/05 was that well equipped
(but it's in the short box).

It certainly seems like the distribution tape, but it's not clear to
me that you have a bootable tape there. If your TS03 is working
and you enter in the TS bootstrap and you get text, then it is
bootable. Dunno where you'd find install instructions for v3, though.
It's *possible* that there is a second tape that you boot first, one
with either an MS or MT boot block on it. It's also possible that there
is a boot papertape. Again, that's before my time (I got started with
RT-11 v4 on floppy).
Is RT-11 the easiest O/S to get installed?
Yes!
I want to get to a point where I
can verify the hardware is all running.
RT-11 or XXDP (DEC's low-level diagnostic monitor) are the way to go
for that. With 28KW of core (not all of the upper card can be used
due to the I/O page, you don't have a lot of OS options. 2BSD is
out, as are recent versions of RSTS and RSX-11. Don't remember what
the requirements for older OSes are off the top of my head.
As far as media devices, I have 3 x RK05, 1 x TS03, 2
x RX01, 1 x TU58.
Nice assortment. Have you checked any of your diskettes or disk packs
for labels that suggest they might be bootable?

PDP-11/10 from the 11/20.

Are you trying to get something historically accurate or just something
runnning well enough to be interesting? How much core do you have in
your 11/20? That might help drive the answer. If you want to run RT-11,
you'll need a storage device on the 11/20. It could be the RX01. If
you want to toggle in a long bootstrap, it could be the TU-58 (but floppies
are easier to find than TU-58 cartridges, and can be reformatted for the
RX01 with an 8" drive and modern to semi-modern computers).

The on-cpu SLU was so bad it was amazing! Every revision of the
processor boards has eco's and enteries in Dec-O-Logs(they never really
made it work). Disabling it is really the kindest thing, sorry for you
GT-40 owners(not that I wouldn't like one).
That looks like an install tape, it would be interesting to know how
much memory V3 uses, I have manuals for V2 and V4, but no real
information on V3.

If you send certian character combinations it "breaks" and I forget what

I just spent some time with it when I got my 11/05 to decide wheather to
build a replacement flip-chip for the cable or disable it and use a SPC.
