??Many of the classic Rocker & Lever Actuator switches from the 1960s & 1970s were discontinued, due to industry consolidation (M&A) in 1990s and the convert or obsolete decisions (RoHS compliance), a decade later. This likely means you will need to ?adopt? to current offerings == OR == plow through remaining discontinued surplus parts. For example, Mendelsons only lists about 5% of their Dayton warehouse inventory. https://meci.com/electronics/parts/switches/rocker.html == These Large Actuators are sometimes referred to as Wide Paddles. C&K refers to this PC board mounting as the V3 Style, VERTICAL MOUNT, V-BRACKET It is still offered for the C&K ?T-series?

Looking for front panel switch

by charlesmorris800＠centurytel.net

> https://www.tedss.com/MT-SPDT-7101 Thanks :) It's only slightly different (the mounting pins look to be a bit closer together than my switches dated 1975, but I can drill a couple holes in the PC board, and swap my matching lever onto it.) Certainly a lot closer than the totally non-matching chrome bat handle unit I stuck in there for now! -Charles -- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus

Vintage Computer Warehouse Liquidation

by tsraguso＠gmail.com

This is my first of many posts that I will make about this sale. I am liquidating a large warehouse filled with vintage computers including Apple, DEC, IBM, Commodore, Tandy/Radio Shack, HP, and more. Many items are currently inaccessible due to large piles of junk and video games. So far, I have found: Apple Lisa 2 Tandy 6000 HD IBM 5251 Keyboard MicroVAX 3900 (currently inaccessible) MicroVAX II (currently inaccessible) Cromemco System One Ohio Scientific Challenger 2p Lots of Apple II series IBM 5110 Piles of VT100s Even more VT220, VT320 Northstar Advantage Osborne 1 Various Kaypros PC clones Commodore B-Series Just about every kind of TRS-80 IBM XT with monitor in box NeXT cube Almost every type of Macintosh Amigas IBM PS/2 P70 HP 3000 (inaccessible) 1970s HP computers Boxes filled with Cromemco and Northstar manuals A pallet of 1980s PC clones (inaccessible) Heaps of CRT monitors Mechanical Keyboards At least 20 Apple Extended Keyboard II's I have barely scratched the surface of the warehouse, and will keep you updated when I find more items, or am able to move the large systems. The DEC terminals are not yet for sale, since I have not yet found the keyboards. I am not taking offers on the entire warehouse at this time. Please feel free to text me with questions Thomas Raguso (832) 374-2803

Looking for front panel switch

by charlesmorris800＠centurytel.net

This fall I decided to restore my first homebrewed computer that I made 40(!) years ago and still have... a 2 MHz 8080A, 1K of static RAM, a 1702A (256 byte) EPROM, cobbled up an S-100 connector for a VB-1B video card, an 8-bit I/O port that used an EBCDIC keyboard (ASCII translation table in the EPROM), and of course a hand-made front panel PC board with blinkenlights & switches. I had a good time learning assembly language (and hand-assembling)... I also toggled in WADUZITDO once or twice. That's a functional interpreted language in 256 bytes plus char in/out routine, for the youngsters ;) I sold the VB-1B years ago, and can't find the keyboard which got lost in a move years ago. So if I want to play with small 8080 programs, I'll need to add a UART (and redo the primitive monitor program for serial I/O instead of memory-mapped display). Recently I bought one of Martin Eberhard's ME-1702A boards with pre-programmed PIC, acquired all the parts from junkbox and Mouser, and just got THAT working. Surprisingly enough, the monitor seems to still have all the right bits after 40 years. Anyway. At some earlier time, I'd either lost (or cannibalized for a PDP-8) one of the switches. Subminiature SPDT toggle switches are readily available >from C&K and Mountain, but I cannot find one with the four-pin mounting bracket and the "ears" to hold the paddle lever pivots. Attached is a picture showing part of the front panel. https://imgur.com/bIrmZt7 Does anyone have a matching switch they're not using?

LISP implementations on small machines

by jnc＠mercury.lcs.mit.edu

> From: Eric Smith > Code can be executed from the MMU PAR registers on processors with > 22-bit addressing (11/23, 11/24, 11/44, 11/70, and J-11 based systems). My QBUS machine is apart at the moment, so I can't verify this before posting, but I don't think this hack works on the J-11 machines; I documented this behaviour here: http://gunkies.org/wiki/KDJ11_CPUs#Code_in_PARs It does work with F-11 processors (/23, etc). Not sure about model A F-11's, which only have 18-bit QBUS addressing. Noel

Off topic- precision tooling

by useddec＠gmail.com

I have a sizable quantity or tooling for sale or trade including : circular blades, mostly Levin, 1 1/4 d, 1/4 arbor from .008 to 03 and probably others. drill bits- Levin. 13mm, .0028" etc.and 15 tubes only some labeled, B & D, Cleveland decimal sets, Precision twist and other companies sizes 60 through over 100 or so.. Morris taps and dies, 0-80 through 0000-160, about 20 sizes. Most are new, but a few might be used. If you have any interest, contact me off list. If there enough interest I'll try to make a detailed list. They are a pain for me to work with, but cheap to ship. I also have larger size taps, die , and bits up to 1 1/2 or so, I think a #3 or #4 Morse taper Thanks, Paul

LISP implementations on small machines

by mark.kahrs＠gmail.com

The first implementation was done for the 7090 by McCarthy (hence CAR and CDR --- Contents of Address Register and Contents of Decrement Register). If you want to see a tiny implementation then look for the PDP-1 implementation done by L Peter Deutsch. There's a book chapter and then I found this report: http://s3data.computerhistory.org/pdp-1/DEC.pdp_1.1964.102650371.pdf

Need DM11 documentation

by jnc＠mercury.lcs.mit.edu

Hi, does anyone out there have any DM11 documentation? The only thing I could find online is the "DM11-BB model control option manual" (DEC-11-HDMBA-A-D) - and it's the impetus for this request, actually. One page 1-5, pg. 15 of the PDF, it has a diagram of which boards go into which slots on the DM11 backplane - and ir has _two_ boards marked M7245! So something's clearly wrong. The DM11 is a fascinating oddball of an interface, BTW. (It's in the 1972 edition of the "peripherals and interfacing handbook".) A lot of its internal state is kept in main memory, and accessed via DMA! This includes the incoming data shift registers!!! So it can really chew up a bus - probably why it was dropped ASAP. I guess when it was done, memory in chips must have been expensive and/or not very dense; and it must have been before the first UART chips. Noel

phone systems, old and less-old

by jwest＠classiccmp.org

I know some peeps here are phone pholks?..See www.ezwind.net/phonestuff <http://www.ezwind.net/phonestuff> One is an old ?bell system western electric?. It seems to have a few 66 blocks just under the cover, a power supply, and some kind of modules that plug in. The other is a Nortel Networks ICS. It feels way too light, not sure if anything is in it. There is another piece of Nortel gear on the wall, seems to be some kind of wireless? thingy called Nortel Networks Call Pilot 100. I know zilch about phone systems, and don?t want to know anything about phone systems ? They were on the wall of a warehouse telco closet that my client just rented and we need the space on the dmarc wall for a rack. If someone wants them, and is willing to pay ship/pack (ups) from 63146 let me know within 2 days or they go to the skip. J

Course materials for MIT 6.031 (c. 1974) scanned

by jnc＠mercury.lcs.mit.edu

> From: Josh Dersch > Any idea what ultimately happened to that 11/45? MIT offered it to me as a gift, but I was a total idiot (and also didn't have future vision), and as I was so busy with the IETF/IESG at the time (which might have been the right call, given how the Internet - note the correct capitalization - has changed the world) I didn't have time to arrange the shipping, and it was given to FTP Software. I recently tried to track it down, to find all the software on it (before I discovered a couple of sets of dump tapes I had made BITD in my basement), and they gave it to one of their employees and it was apparently scrapped. > Are the Algol and LISP available anywhere? Not up yet, but if anyone wants either, I can try and find time to get them up. For the Algol interpreter, all I have is the binary (runs under the MIT-hacked PWB1 - not sure if it would run until vanilla V6) and the manual; the source was unfortunately not saved when the drives were moved from DSSR/RTS (the DELPHI group) to my group, CSR. (Although there may at one point have been a copy retained on a now long-lost pack, along with a lot of other 6.031 stuff, like problem sets sources; I do have a file which is a listing of the disk contents.) For the LISP interpreter, we do have the source (in MACRO) too. Alas, to build it, one needs the 'bind' binder (which groks .REL files, which are based on DEC's relocatable binary format), which was i) written in BCPL, and ii) the current binary can't rebuild itself (I forget the details, whether it's the BCPL compiler, the MACRO assembler, or 'bind' which can't be re-built; it was a couple of years back I was playing with all that). Luckily, we do have some older binaries which can probably be used to work around the issue. Of course, if one just wants to use the existing interpreter binary, one can avoid all that. Noel

IBM 5110 transformer?

by mattislind＠gmail.com

A friend of mine is trying to repair a IBM 5110. He is convinced that the transformer is bad. Anyone knows the spec of the transformer? Someone that has a spare? Looking into the tech documentation tell me that the machine requires +/- 5V and +/- 12 V and also +8.5V A very rough guesstimate based on the number of wires from the PSU to the backplane would give 20A 5V, 4A +12V, 4A +8.5V, 1A -5V and 1A -12V. Anyone with a better guess? /Mattis

VCF Midwest 14 Wrap-Up

by silent700＠gmail.com

Hello all - VCFMW14 has come and gone and we're left with lots of photo galleries, a few videos and hopefully fond memories for all. It was a new venue this year and an unprecedented (and unexpected - seriously we filled the place) turnout. Wheels are in motion toward doing it again next year but for now we're just going to rest a little first. Here's a link to all of the known-thus-far pics and vids: http://vcfmw.org/past.html The videos of the actual VCFMW Talks are being scrupulously compiled and encoded and another announcement will go out soon when they're ready. For now, check out the cool setup time-lapse and visitor review videos at the link above. It's looking like we're going to do a reprint run of this year's official shirt because so many were unable to purchase one at the show (see the bit above about unexpected turnout). Maybe you'd like one, too. There's a size survey form in our latest mailing list message here: https://us18.admin.mailchimp.com/campaigns/show?id=389367 And finally a big THANK YOU to all who donated, displayed, volunteered and attended in order to make VCF Midwest the most enjoyable and exhausting weekend of the year for us. -j

Fwd: [TUHS] Recovered!!! The Georgia Tech Software Tools Subystem for Prime Computers

by aek＠bitsavers.org

Have been on the road, and I just noticed this announcement on the TUHS list. I'd been trying to find this for a long time -------- Forwarded Message -------- Subject: [TUHS] Recovered!!! The Georgia Tech Software Tools Subystem for Prime Computers Date: Tue, 24 Sep 2019 22:45:29 +0300 From: Arnold Robbins <arnold at skeeve.com> To: tuhs at tuhs.org Hello All. Believed lost in the mists of time for over 30 years, the Georgia Tech Software Tools Subsystem for Prime Computers, along with the Georgia Tech C Compiler for Prime Computers, have been recovered! The source code and documentation (and binary files) are available in a Github repo: https://github.com/arnoldrobbins/gt-swt. The README.md there provides some brief history and credits with respect to the recovery, and w.r.t. the subsystem and C compilers themselves. Credit to Scott Lee for making and keeping the tapes and driving the recovery process, and to Dennis Boone and yours truly for contributing financially. I set up the repo. For anyone who used and/or contributed to this software, we hope you'll enjoy this trip down memory lane. Feel free to forward this note to interested parties. Enjoy, Arnold Robbins (On behalf of the swt recovery team. :-)

Hi, A friend tells me that there is a Hewlett-Packard HP3000/917LX available in Vacaville (no word as to price, but I suspect it's free ... the owner wants it to go to a good home). Reportedly running, with additional "mini-tower" (PC size or less) of external disks, a DTC (Distributed Terminal Controller, lets you have up to 32 RS232 terminals attached (depending upon model of DTC)), and an external tape drive (probably DDS, but I don't know for sure). If interested, email me at sieler at allegro.com and I'll put you in touch with the friend of the Vacaville guy. thanks, Stan

Update: Received my 50lb Datapoint 2200 computer from Austria via regular post.

by tosteve＠yahoo.com

Found a Datapoint 2200 in Austria that I wanted - I asked seller Viktor to pack it well, by wrapping it several times in big-bubble bubbewrap, until it was just a giant cube of bubble wrap. See pics here: http://oldcomputers.net/box/ ? The cover was actually sent separately in another box so it didn't crushed by the 50 pound system. First, I have to rewire it from 220vac to 110vac. Second - what to do about that screen?

WTB Metcal workstand

by marvin＠west.net

A friend of mine, Harold Fue, has been selling new and used soldering equipment for many years, and may well have what you are looking for. My knowledge of Metcal is limited, but I bought a number of new tips, a used SP-200 unit with handpiece and the handpiece holder from him a couple years ago. A search on google for "harold fue santa barbara" came up with his contact information. He has been selling at Dayton Hamvention for who knows how many years, but an auto accident a year or so ago totaled his vehicle and slowed him up (he is in his mid 80's) >from doing that.

NOS old media and other stuff available

by sales＠elecplus.com

Send him an email, and he can send you a list. He is NOT interested in selling 1 or 2 boxes of floppies. He needs volume deals. I have a list of items available from a Value Added Reseller that closed several years ago and had these items in storage. All items are OEM, NOS and include LOTS of data media spanning generations (Round Reel data tapes, 4mm Cassette tapes, ????? Tape Cartridges, 35???, 5.25??? and 8??? Diskettes), Trillium and EnGenius phone equipment, various electronics components and packaging materials. Have images of many of the items available.

DEC RP04 service manual available

by jnc＠mercury.lcs.mit.edu

> From: Evan Koblentz > I know of two RP04 drives in the wild. One belongs to a private > collector. VCF has the other. Right, but does VCF need it scanned? Oh, one other place that might have one: the MIT MC KL10 had a couple of RP04's; when it was taken away to Scandanavia, they might have gone with it. I think that machine is now at LCM? Noel

Cleaning an old keyboard

by jnc＠mercury.lcs.mit.edu

> From: Al Kossow >> This is documented in NASA's official history of Project Mercury, for >> which it was invented. > could you post a pointer to the document where this appears? If the reference is to: Lloyd S. Swenson, James M. Grimwood, Charles C. Alexander; "This New Ocean: A History of Project Mercury"; SP-4201; NASA; Washington; 1966 "WD-40" does not appear in the index. There's another less likely book ("Project Mercury: A Chronology", or something like that), but I can't be bothered to drag it out and look, because I'm pretty sure that's incorrect. My understanding is that WD-40 was invented to protect the stainless steel skin of the Atlas ICBM (which was often left un-painted), built by Convair. I do recall seeing this in one of my Atlas books, which is alas currently not shelved, and I don't have time to find it. FWIW, Wikipedia agrees. The rest of that post (about how it's a waxy material in a solvent) is I think correct; it certainly agrees with its original intended usage (above). Noel

DJ11 Maintenance Manual available

by jnc＠mercury.lcs.mit.edu

> From: Pierre Gebhardt > there seems to be a copy of the maintenance manual in the unibus-folder > on bitsavers: EK-DJ11-MM-003_DJ11_Maint_Man_Aug76.pdf Argh! I looked in that folder, but didn't see it! (And Manx says its not online, either.) > Would be worth checking the document revision. Mine's earlier: DEC-11-HDJAA-B-D. > What is missing, however, is an engineering manual with the schematics. Well, the M7820's will be the same as in the DH11. The M7285 and M7279 are DJ11-specific, though. I was going to say that 'does anyone even have any DJ11's any more, to need the drawings' (they're like lobotomized DZ11's - the serial line config is done with jumpers!), but on looking it turns out the RICM probably has some in their -11/45's.

Cleaning an old keyboard

by trash80＠internode.on.net

I resurrected an old keyboard and mouse I like. Not wishing to gross anyone out but it looks like over time there was a build-up of oil etc from my hands etc and over time being stored away its turned to a really almost hard paste like stuff on both the mouse and keyboard. I've tried number of agents to clean it off but limited success. Any tips please. Kevin Parker

Vintage computer store hints in Minneapolis?

by jplist2008＠kiwigeek.com

Morning all; I was up in Minneapolis over the weekend and will probably be back next weekend - I was wondering where the local geeks might go for some nifty goodness (for sale or just to gander at)? When I was up there I hit FreeGeek and picked up a SCSI SyQuest EZ135 external drive and a couple of carts. I also rolled through The Ax-Man... for 3 hours because I'd never even heard of the place before and was absolutely astonished at what I'd found. (If you've never been, you _must_ go) But I thought I'd poll and see what else might be found up there? I'm mostly a non-PC collector (Sun/SGI/Digital/+ random things) - but easily amused. Speaking of, there's a set of power supply modules for a PDP at The Ax-Man on University. There were several h744s and 745s and and an h754, although one of them someone has started to pry apart and the Molex (?) connector is broken from the PCB, although the pins were still attached to the board. They were asking $9.95 for each and I wasn't willing to buy and hope they worked. Cheers; - JP
