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.

Fwd: [Simh] Resurrecting the ARPAnet IMP

by jim＠deitygraveyard.com

I thought this was rather interesting. ---------- Forwarded message ---------- From: Bob Armstrong <bob at jfcl.com> Date: Fri, Nov 22, 2013 at 9:41 AM 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 _______________________________________________ Simh mailing list Simh at trailing-edge.com http://mailman.trailing-edge.com/mailman/listinfo/simh

Emulex QD0110202 F.R.D. mode on a LSI-11 system

by Mark＠Misty.com

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 -- Mark G. Thomas (Mark at Misty.com)

Anyone have a Scientific Micro Systems SMS-1000 PDP-11 system?

by glen.slick＠gmail.com

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. -Glen

Looking for historical info on the Soviet UM1-NK

by steve＠tronola.com

Hi Jan, >I've found some stuff; > >Here is some history: >http://www.computer-museum.ru/books/vt_face/9_staros_1.htm > >And here is a general summary of the machine: >http://www.computer-museum.ru/books/vt_face/prilogenie_16.htm --- 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, Steve L.

BA23 common component failures?

by b4＠gewt.net

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. -- Cory Smelosky http://gewt.net Personal stuff http://gimme-sympathy.org Projects

cctech Digest, Vol 123, Issue 31

by ceforman＠sbcglobal.net

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. >________________________________ >Date: Tue, 26 Nov 2013 21:59:38 -0500 >From: Ethan Dicks <ethan.dicks at gmail.com> >To: "General Discussion: On-Topic and Off-Topic Posts" >??? <cctalk at classiccmp.org> >Subject: Re: Seeking a few game-related DEC PDP-11 items >Message-ID: >??? <CAALmim=VTMLp9aw1Gt2MNCqh-OcxKZvjDfHjbOO1NhS47-pvzw at mail.gmail.com> >Content-Type: text/plain; charset=ISO-8859-1 > >>>C.E.

Keytronics caps-lock mechanism

by snhirsch＠gmail.com

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? Steve --

excess documentation near Boston

by akb+lists.cctalk＠mirror.to

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. --cheers --akb

NEC PowerMate 1 Plus and Video 7 VEGA

by thrashbarg＠kaput.homeunix.org

Hi all, I'm wondering if anyone has the setup disk(s) for an 80286 NEC PowerMate 1 Plus. I've found various utilities for other models but they don't clear the error message about the CMOS configuration on boot. The files I've tried are at ftp://ftp.necam.com/pub/desktop/PowerMate/Old.PowerMate/ I'm also after the utility disk for a Video 7 VEGA Deluxe EGA card, which came with it. http://stason.org/TULARC/pc/graphics-cards/U-Z/VIDEO-SEVEN-EGA-V7-VEGA-DELU… Can anyone assist? Thanks, Alexis K.
