IBM 3990 Storage Controllers, Dallas, TX $100

by frustum＠pacbell.net

Since I know the list has a number of collectors of IBM big iron, here is a link to an auction for *five* IBM 3990 storage controller cabinets. I know nothing about such equipment. From the picture, I can't tell if the unit has the optional ice maker and cold water dispenser. https://www.shattuck.com/auction/itemdetail.aspx?itemid=1949 Auction ends 3/23/2006. Part of the text says, in part: Removal by appointment only. Removal must be completed by no later than 3 days after close of auction. Items remaining beyond this time will be forfeited. Pick-up times are 9 to noon, and 1 to 3:30pm, Monday through Friday. Removal: Buyer is responsible for all dismantling, rigging, crating, loading: hauling at own risk and expense. THE AUCTIONEERS DO NOT FURNISH PERSONNEL OR EQUIPMENT FOR LOADING!

For those who may need one: I've placed a Vector brand S-100 extender board up for grabs on That Auction Service Which Must Not Be Named. A seller search on 'bftbell' should turn it up.

PCI DSSI adapters; was [Re: FA: DEC RF-71 Disk Drive]

by compoobah＠valleyimplants.com

DEC DSSI VMScluster Installation and Troubleshooting Guide (EK-410AB-MG. D01) talks about all the different ways to cluster AXPs and VAXen using DSSI (but doesn't cover PCI, only EISA + proprietary DSSA adaptors). Evidently, DSSI clusters were used often enough. Seems that by this date, they were implemented mostly with HSDs rather than DSSI drives.

QNX, Useful applications

by mtapley＠swri.edu

All, regarding QNX, there must be a reasonable user base out there. The QNX on x86 guys have cranked more on the Distributed.net RC5-72 project than the NeXTSTEP/x86 crowd, and are still active. I also note the existence of a QNX on ARM client, which implies QNX ran on some ARM platform as well. Palm? To tie in a different thread, regarding "practical" applications for vintage computers, Distributed.net seems like a natural. It's not exactly Earth-shaking science at the moment, but it's a big problem that breaks naturally down into a lot of very small pieces, so it's something classic systems can actually practically contribute to. I would *love* to see a VMS/VAX client, and to my knowledge there are several VAXen on the net now doing not so much at any given moment. Do any of you VMS gurus have time and inclination to combine the VMS/Alpha and the NetBSD/VAX clients and let us put VMS/VAX on the charts? And of course, I don't know *why* no-one has put the MacOS 6-9 client back active. I actually have a copy of CodeWarrior, so let me know if you have time, ability, and inclination, but lack of CodeWarrior. We can work out a loan. Personally, I have inclination and CodeWarrior, but neither (really) time nor ability, though I'm trying to work on it. I don't suppose an 8-bit client is practical - I've never heard of a C++ compiler to 8-bit target - but it would be really cool to crack a block of keys on my Rainbow under CP/M-80. Sigh. Does anybody have any positive/negative experience with distributed.net that I should know about? http://www.distributed.net/ for more info. Hit "statistics", pick a project, and look for "mtapley at swri.edu" to see my meager contributions so far, or go straight to http://www.distributed.net/source/ to grab the public part of the source. -- - Mark NEW CELL PHONE NUMBER: 210-379-4635 2-way pager until end of March 2006: 888-733-0967 office is still: 210-522-6025

"party line" for terminals?

by legalize＠xmission.com

I purchased an odd terminal display (no keyboard) from ebay recently and it arrived today. Its manufactured by Westinghouse Canada and has 3 ports that look like DB25 female style and 1 DB9 style female port that says "party line". I'll post more detail later, but oddly enough this terminal monitor doesn't appear to have a keyboard port, unless it connects to one of the data ports on the back. What is the "party line" port and what's it used for? A search of the cctalk archives didn't yield anything. -- "The Direct3D Graphics Pipeline"-- code samples, sample chapter, FAQ: <http://www.xmission.com/~legalize/book/> Pilgrimage: Utah's annual demoparty <http://pilgrimage.scene.org>

PDP-8/L teletype interface

by sb＠thebackend.de

Hello everyone! I wrote here about my PDP-8/L a long while ago already. This is my current status: All instructions seem to work (only tried the simplest form, i.e. 5001). Core memory is mostly untested. The places I used work and retain their content. Examining and depositing works. AC, PC work: I can execute small loops using jumps and conditional skips etc. So as far as I tried it everything seems to be alright. Now I wanted to revive the teletype interface to load and try more complex programs and that is where I am stuck now: The machine has the M452, M706 and M707 modules. W076 was missing so I got a W076X from Vince that does RS232 (thanks again :-) as well. I don't have a real teletype. I used this small program to try and send characters from the switch register: 0000 7200 CLA 0001 7404 OSR 0002 6046 TLS 0003 6041 TSF 0004 5002 JMP 003 0005 5000 JMP 000 The program loops like crazy but nothing happens to the serial output. If I connect a oscilloscope to the data lines of the M707 I can see the input bits change as I push the buttons on the front panel and step trough the program. The input clock is there as well (so I assume the M452 is working) but no data stream comes out of the module. Writing this I realize that I didn't check the device selector inputs. I'll do that tomorrow. I know how to operate an oscilloscope and I have some experience with electronics but I'm not very good at reading logic and I only ever spent a couple days with this computer so I need some help here. Is there anything I have to look for especially? Next I tried receiving characters. I hook my PC up to the W076X and start sending more or less random characters. They show up on the backplane side of the W076X module and on the input of the M706 but no data comes out either. The clock input is low all the time. Two of the select bits seem to be low all the time even if I execute the following program: 0000 6032 KCC 0001 6031 KSF 0002 5001 JMP 0001 0003 6036 KRB 0004 5001 JMP 0001 Actually the above program completely hangs the computer. I stays in "run" state and on address 0002 whatever key I press. That never occured before. As you see I don't know too much about this computer. Am I using the right commands at all? I started reading the documentation and schematics (it is truly amazing how complete they are!) but I am not sure what to look for - what the signals on all the different "clear"-inputs of the M706/707 have to look like for example. Any hint is apprechiated! Sebastian PS: It's been a long day so don't mind me if I don't make too much sense...

Adds Computers and the Tandy 10

by CCTalk＠catcorner.org

OK, I'm trying to research the Tandy 10. This was a machine built into a desk with 8" drives. I have not been able to find much on it. I read somewhere that it was an Adds model 10. Possibly has an 8080 CPU. Does this ring a bell with anyone? This would have been around 1978. Thanks, Kelly
