What unit numbers to the drives on the second controller show up at? I have
a CQD-223 as the primary controller and an RQDX3 as the second controller
with an RX50.
I thought this was rather interesting.

Subject: [Simh] Resurrecting the ARPAnet IMP
To: simh at trailing-edge.com
This summer a group of us worked together to resurrect the original
ARPAnet IMP software, and I?m now happy to say that the IMP lives
again in simulation. It?s possible to run the original IMP software
on a modified version of the H316 simh and to set up a virtual network
of simulated IMPs talking to each other. IMP to IMP connections,
which would have originally been carried over leased telephone lines,
are tunneled over IP. As far as we can tell, everything works pretty
much as it did in the early 1970s. IMPs are able to exchange routing
information, console to console communications, network statistics,
and they would carry host traffic if there were hosts on the network.
The hooks are in there to allow simh to support the IMP side of the
1822 host interface, and the next step would be to recover the OS for
an ARPAnet era host and then extend the corresponding simulator to
talk to the IMP simulation.
If you?d like to know more, you can read a detailed account of the
whole adventure here ?
http://walden-family.com/bbn/imp-code.pdf
Everyone involved has agreed to release their work under the same
terms as Bob Supnik?s original simh license, and I?m looking for
suggestions as to how to handle that. We could just ZIP everything up
and host it on the website along with all the other BBN and ARPAnet
documentation. If the community considers the simh extensions for the
BBN hardware to be of general interest then it could be submitted to
the current simh repository. Or it could go somewhere else - I am
open to suggestions.
Thanks,
Bob Armstrong

Hi,
Does anyone have the manual or at least the ODT prompt commands to
get into F.R.D. mode on an Emulex QD0110202 controller?
So far my google-foo has failed on this one. The closest I have found
so far is for a QD21, but I think close but no cigar in this case.
Thanks,
Mark

While on the subject of SMS, does anyone have an SMS-1000 PDP-11 system?
http://www.bitsavers.org/pdf/sms/qbus/
3001076A_SMS1000oem_Feb87.pdf
The built in storage controller is supposed to be fully MSCP
compatible and while I have been able to get RT-11 working on the
internal hard drive I have never been able to get it to work with
RSTS/E or 2.11BSD. It has been a while since I've powered up the
system and from what I remember the firmware would display a version
less than 1.0, maybe something like 0.8, or maybe the version was
written on the firmware EPROM labels. Also, the CSR address choices
available to configure the built-in MSCP controller in my SMS-1000
don't match the CSR address choices listed in the manual.
If anyone else has one of these SMS-1000 systems I would be curious to
know what firmware versions you have, and whether you have been able
to get anything other than RT-11 working with the built in MSCP
controller.

--- Thank you so much for digging up the additional references. It's interesting that it differs somewhat from the existing ones I have insofar as word length and power consumption. The new figure of 200-Watts seems more plausible than the 100W the other sources give. The new reference also reveals that production didn't start until 1963. With no mention of the previous UM-1 model, one can only assume that it wasn't produced in quantity.
--- Truly useful parts of the puzzle.
Thanks,

Evening,
What're the components most likely to fail in a BA23 PSU? I have one that
keeps pouring smoke out of it...yet I can never see a component that's
burnt, punctured, or other stuff like that. I also never hear an arc or
anything exploding. The PSU also squeals when powered down.
Yes. It seems to STILL work despite smoke coming out of it. Haven't
confirmed after today's magic smoke release though. I'll test again once
I get a warmer day.

Hi Ethan,
Yeah, that's exactly the sort of thing I'm looking for.? I have a few early Infocom titles for DECmate II and Rainbow:
http://yois.if-legends.org/vault.php?id=553
But the holy grail has always been the PDP-11 version of the original mainframe Zork.? I've seen the scans, and have held an original printed version in my hands when I visited a German collector years ago, but am looking for an original for myself.? Same with the map in DEC Professional.
The TRS-80 Personal Software Zork is also fairly rare and sought-after, so congrats on finding that.

I pulled my Corvus Concept keyboard apart for cleaning and managed to
knock loose the white nylon "collar" around the caps-lock key mechanism.
Apparently there was a microscopic pin inside with an equally microscopic
load spring behind it... At any rate, no toggling anymore :-(.
Is there anyone on the list who may have cannabilized a Sun 4 keyboard and
can spare the caps-lock assembly from it? Or, any suggestions for getting
this to work again?

I'm dumping about 40 manuals, pics at:
http://www.flickr.com/photos/61575639 at N06/sets/72157638073631285/
Mostly DEC/Digital from the mid-90s (VMS 5.x guide, OS/2 1.3 manual,
various Storageworks things, OpenVMS cluster config, Alpha 3000 owner's
manual, etc.) but a bit of everything... Hypercard, ISDN, Sun E450
owner's manuals, etc. I'll probably try to ebay the NeXT manuals.
This stuff is free if you show up in Somerville Massachusetts soon to
collect it, and I could be convinced to pay to ship it to a public
archive (if bitsavers or archive.org wanted any of it, for example), but
I'm likely to want money from anyone else who wants me to ship things;
it takes a lot of time and attention away from sorting stuff.
