IBM 360 and 370 control panels available

by jdykstra＠nortelnetworks.com

Data Sales in Savage, Minnesota has a number of 360 and 370 control panels available. During my search this morning, I found panels from several Model 30's, a Model 25, a Model 44 and a Model 65. They also have a number of 370 panels, although I can't quote models--those machines are after my time :-) Condition varies widely--email me for what I remember about a particular panel. Contact info: Jim Breckner, site manager, (612) 890-9047, <jim(a)lineserve.com>. Please mention my name if you contact them--I would like to go back and take some photos of other IBM gear they've got, and they're more likely to tolerate the inconvenience if I'm bringing them some business. Other than that, I have no relationship to these people. NOTE--These panels are from machines that have already been scrapped, many more than two decades ago. I too would have liked to see these machines in running condition, but given their size, power and air conditioning requirements, etc., I doubt that there would have been very many takers. Does anyone know of any intact and running System 360's? How about System 370's? ---- John Dykstra jdykstra(a)nortelnetworks.com Principal Software Architect voice: +1 651 415-1604 Nortel Networks fax: +1 612 932-8549

FW: VAXstation KVM switching

by baileyj＠whitlock.com

Hello, My name is John Bailey and I am an integtrator of data projection and display systems in Research Triangle Park, North Carolina. I noticed this board on a search for VAX info and thought you might be able to help with a problem I'm working on. I need to control several VAXstation 4000.60 machines with a single keyboard/mouse/monitor. The environment is a telecom network management center with limited space per operator. Do you have any suggestions or know of any hardware that would accomplish this? The regulars (Black Box, Cybex) are no help. If not, do you know if the machines will operate without a keyboard and mouse (once booted), or support multiple connects and disconnects of keyboard and mouse while operating. Any advice greatly appreciated, John B.

They were in use between 11/34's and an Amdahl until about 4 or 5 years ago. One has LEDs, the other incandescent lamps. -- Pete Peter Turnbull Dept. of Computer Science University of York

Do you have the 1.25" thick volume 3 or the 1/2" thick volume 3? Other volumes are "maintenance training manuals" (1,3), 2,3, and 1,2.. Seems DEC only intended certain manuals to go to the public [1,2,3]. I have 2 versions of each set with maintenance trainers to bring me a current running total of 5 sets of PDP-8/E maintenance guides. I have so many other weird manuals and options I am hoping you, Alison, or Megan have heard of them: A 1964 PDP-8P (all transistor).. I have prints. DeCastro designed it. Could be the straight-8 but I doubt it. DX-36X (looks to be a straight-8 to IBM 360 interface) RSX-11B, RSX11-C ..before RSX-11D was released. Here's a real weird one (I'll put up pictures soon): A TU56 that does not look like a TU56.. No "unit number switch". Only On/Off, -> , <- ,nothing else. Two drives. Standard DECtape, NO CARDS inside. The entire drive electronics are on an external backplane. NO, it doesn't look like a TU-55 either. Most useful stuff to me so far are the Microfiche and Internal Tech Notes for my 8/S. The tech notes identify a few hundred different common problems with the 8/s and how to fix them... many from internal DEC engineers. I also have these for the 8,8/i, and 8/l. I wonder if Dag only got hardware? I am certainly receiving a lot of internal stuff. Also, what are the current licensing issues with RT11, RSX, and RSTS? A few list members have offered to help me read in all the different versions so I can post them on the Internet. john http://www.pdp8.com/ > >-tony >

HP guru needed!

by dylanb＠sympatico.ca

I saw an HP mini at a local warehouse.... Here is what I saw/what I have been told: It is an HP-2 (is there such a thing)? It has a high speed paper tape unit on it. It has a disk interface box (about 5" high). I have not seen the CPU as it was not in a position to see it's front panel. I tried a search but get 5000 HP-2 laserjet webpages.

I fact, I have a strong feeling I will be getting a few. Please post back the exact model number as that will tell me the baud rate. They made two models: "A" version which is 20mA 300 baud. and a "B" version which is 20mA 2400 baud. I can post pinouts for the group if needed once I get the full model number. OT: so far I found two more PDP-16s, RSX-11B,C - papertape??, (I thought the first version was "D"), and about a million other things I won't even try to list right now. I have also learned the art of stacking DEC handbooks 50 high... Another thing I did not know was that there are 5 different PDP-8e maintenance manual sets: Preliminary (3), Processor (3), Internal Options (3), External Options (3) and Lab-8/e (1). Finally, found a pile more of PDP-1 software including Spacewars (with both patches) and OPSYS :-) john http://www.pdp8.com/

I can post pinouts for the group if needed once I >get the full model number. Mine started out life as the 300 baud version, but was "field modified" to 2400 baud by changing some of the timing capacitors. (No crystals here, the baud rate is set by a capacitor and tweaked with a variable resistor.) It was also "field modified" to RS-232 by adding a small circuit board to the 0.1"-pitch header inside. (That was done by me!) The circuitry inside is really quite simple, just plain old TTL and some optocouplers for the 20mA interface. What *I* like about the PR/S01 is: 1. Very portable, down to the carrying handle on the end :-). 2. It doesn't use a bulb, but instead a small array of infrared LED's for scanning. For those who've had to deal with loose bulb connections or dead bulbs while in the field, this is a *real* godsend. -- Tim Shoppa Email: shoppa(a)trailing-edge.com Trailing Edge Technology WWW: http://www.trailing-edge.com/ 7328 Bradley Blvd Voice: 301-767-5917 Bethesda, MD, USA 20817 Fax: 301-767-5927

One odd thing about the prs01 is that the outermost pin on one of the two connectors is in use. It is a no-connect to either the terminal or the interface card (which uses the middle six pins out of eight, IIRC). Thanks, John. -ethan ===== Infinet has been sold.

Famous & infamous computers of the 70's & 80's.

>> Computer with the worst pitchman: Bill Cosby. (TI-99/4A) >Again, Atari. Remember all those Alan Alda commercials in the 80's?
