Hi,
This was my home PC before the days of IBM PC and Microsoft.
It goes back to late 1970's and early 1980's.
Comes with RT-11 operating system on RX02 floopies, manuals,
printer, and VT100 terminal.
Located in Merrimack NH.
I'm not on this mail list so reply to me directly or call.

Is the person who acquired this going to "part it out" to others
or keep it for themselves?

I have been in touch with Ken. He has a local person interested. If that
does not pan out, I will be going up to pick it up this weekend.

Jerome Fine replies:
Since I switched to using RT-11 / TSX-PLUS and other
PDP-11 software under these OSs using an emulator that
runs 15 times as fast as a real DEC PDP-11/93, I don't
really have much interest in the real PDP-11 hardware.
And since I am a software addict, that suits me perfectly.
BUT, I am attempting to preserve as much RT-11 / TSX-PLUS
software as possible. I am in the last stages of getting V1-0 of
a CD with 13 different distributions of RT-11 ready (from
V1-15 to V05.03). So having access to as many of the old
RT-11 distributions as possible is the goal. If possible, I would
like a copy of all of the RT-11 distributions and the layered products.
Are there any RT-11 distributions among the media, including
BASIC and FORTRAN? Is there some way that you could
copy them?
Sincerely yours,
Jerome Fine

Ken was nice enough to give me this machine. I picked it up today. Here
is what was included:
PDP-11/23 with dual RX02 floppy drives containing the following cards:
M8186 (KDF11)
M8044-DF (memory)
M8029 (RX02 controller)
2 x M8047-CA (serial interfaces, memory)
Also included were the following cards:
3 x M8186 (KDF11)
M8044-DB
M8029
4 x M8047-CA
M8027
M8043
None of the KDF11 CPUs had the FPU chip. They all have the MMU.
I removed all of the cards and tried powering up the backplane. The
power light didn't come on and there was little or no voltage on the
backplane power connector. The unit came with an extra power supply so
I swapped the supplies. I now get the following voltages:
+12 measures at 11.21 volts
+5 measures at 5.03 volts
-12 measures at -5.83 volts
Should this power supply produce the correct voltages with no load on
the backplane? Any idea as to why the -12 voltage is off by so much. I
assume this is a problem. I haven't tried plugging any of the cards
back in because I'm afraid the wrong voltages will fry something. Can
anyone suggest how to proceed?
I also got a LA-180 printer and a VT100 with the VT125 upgrade. Is
anyone interested in either of these? They're really too big to ship so
it would have to be pickup in Bedford, NH.
In addition to the hardware, I got documentation for RT-11 V4 and
RSX-11M. I already have documentation for RT-11 and don't need the
RSX-11M documentation. Would anyone be interested in either of these
sets of manuals. They aren't in great shape but they are certainly
readable. Mostly, they're dusty.

New subject: PDP-11/23 up and running RT-11
I solved my boot problems and now have my new PDP-11/23 booting RT-11!
Now I just have to sift through the boxes of floppies to see what
software I have. Apparently the -12 supply isn't necessary to boot the
system.

Hmm... maybe you should check your comm ports... I know that's one thing
that's inconsistent in the DEC world - reliance on -12V from the bus.
The first rev of Qbus COMBOARD pulled -12V from the bus for the 1488/1489
EIA level shifters. We shipped a board to an early adopter and it failed.
Apparently, that particular chassis did _not_ provide -12V (I don't recall
what the customer had, but we would have tested our design in a BA-11M
and a BA-23).
Rev 2 has a +5/-12V converter in the lower corner. I still have a gross
of them from unbuilt stock. Many modern designs have moved to MAX232-like
drivers; we might have, too, except we were supporting two fully-handshaked
sync serial ports - that's a lot of MAX232 chips and (at the time) expensive
tantalum caps. I think our cost on the voltage converters was on the order
of $12-$17 each, which was marginally less expensive than changing driver
chips, but the engineering to retrofit it to an existing design was trivial.
We also drove 50' cables routinely... not sure how well a MAX232 works over
longer wires.

New subject: VT100 with VT125 upgrade and DECprinter I (LA180)
I have a VT100 with the VT125 upgrade installed and a DECprinter I
(LA180) available for pickup in Bedford, NH. Is anyone interested? I
got these along with a PDP-11/23 system and don't have room for them.
If no one is interested I'll probably end up being forced to haul them
off to the dump.

The VT100/VT125 and the LA180 have been claimed along with the set of
RT-11 V4 manuals and the RSX-11M V3.2 manuals.
Thanks to everyone who offered to take this equipment. It's nice to
know that there are people who want this stuff. I would hate to have to
actually trash any of this old equipment!
