Update #3: I have found many examples of rare IBM gear from the 1960s inside the warehouse. These include: 8x IBM 029 keypunch keyboard Boxes of IBM keypunch parts 2x IBM 552 Interpreter 1x IBM 083 Card Sorter 1x IBM 4505 Display Station I have been unable to find anything about the 4505 display station. Does anyone know any details about this item? It resembles an IBM 2260, but the keyboard is not built-in, as in the 2260. I am taking offers on the items listed above. Thomas Raguso

VCF PNW: 2nd call for Exhibits, Speakers and Volunteers

by mbbrutman＠brutman.com

Just a friendly reminder ... VCF PNW 2020 will be on March 21st and 22nd at Living Computers:Museum+Labs in Seattle, Washington. We are looking for exhibits, speakers and volunteers. Presenting an exhibit or speaking at the event takes a little time but it is not difficult. And the reward is that you get to share something that you are passionate about with like-minded people, usually over 1000 of them. Exhibits range from small homebrew machines all the way up to high dollar bigger-iron. (I didn't say big iron because we have not had anybody move anything in with a forklift yet.) Pictures from previous years and details on what to expect can be found at http://vcfed.org/vcf-pnw . Volunteering is pretty easy too; we usually just need a few extra hands to do setup, teardown, and some minor tasks. In between you get to enjoy the museum and the event. If you have special skills we'll put those to use too. If you are thinking of traveling from outside of the region there is plenty to do in Seattle while you are here. Local attractions include the Connections Museum, the Pacific Science Center, MoPOP, the Boeing factory tour, Mr. Rainier, etc. Victoria, British Columbia is also a short distance away. See a more complete list at https://goo.gl/3emMWH . Five months seems to be the distant future but we all know how quickly it will pass. If you are mildly curious or have a question don't be shy - I'm happy to explain the event in more detail. Regards, Mike mbbrutman at brutman.com or michael at vcfed.org

Jacquard Systems

by aek＠bitsavers.org

https://www.ebay.com/itm/372814919055 I'm surprised there is any interest in these. I bought some docs/sw on eBay years ago for one of these and have never run across anyone that had a system.

Yahoo Groups going away

by paulkoning＠comcast.net

A bit off topic, but I figure a number of us are interested in this older "social media" mechanism. https://arstechnica.com/information-technology/2019/10/yahoo-is-deleting-al… So if you subscribe to any Yahoo groups, or value any of that content, be sure to archive it before your friendly telco sends ALL of it to the bit bucket. paul

Lear Siegler terminal

by sales＠elecplus.com

I recently purchased one of these, and it arrived in rather sad shape. It does power on. Is there anyone out there who would give it a good home? The housing is cracked in 2 places, and a lot of the key caps got lost before it arrived at my door. Make offer if interested. I will pack it well for shipping, or it can be picked up. https://drive.google.com/open?id=1OvlRYmr1sC9xvZPAImedqUl7nh11Rs_K Cindy Croxton Electronics Plus 1613 Water Street Kerrville, TX 78028 830-370-3239 cell sales at elecplus.com -- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus

FTGH Decstation 5000

by trash80＠internode.on.net

FTGH Decstation 5000 * Decstation 5000/125 - also houses a CD drive * 2 Expansion storage boxes - one has a tape drive and the other one has a floppy drive. * 2 very large and heavy RGB Digital monitors - one has both Digital and Sony branding on the back of it. I haven't dug the other one out as it's in a corner and is dam heavy but it looks the same as the other one. * A box of spares including a keyboard, two mice, a CD drive, some cables, a couple of CPU's, three genuine HDDs and a big bag of RAM I've never powered it up - it was a rescue - I believe it was a server at a TAFE college in Adelaide, South Australia. I am located in south western Victoria (Australia) Kevin Parker 0418 815 527

Anyone have a firmware dump for Teleray Series 10 terminals?

by ethan.dicks＠gmail.com

Hi, All, I was recently at the CompuServe 50th Anniversary event which included a tour of our old building at 5000 Arlington Center Blvd, where I worked in 2001-2002. The old data center is still in operation, being rented out by Expedient as a cloud hosting and co-location facility. One of the highlights of the tour is an old Teleray 10T they found when they moved in 9 years ago. They have it cleaned up and on display in their conference room. I did a little digging and quickly found the docs on Bitsavers (thanks as always, Al). What struck me was the appearance of the mainboard. I went up into my attic, and wouldn't you know, I _have_ one, labelled "Model 10C" - same board but (formerly) with special feature firmware to be a 10C. What I don't have is ROMs in the ROM sockets. :-( It's five ;places for standard 2708 EPROMs. From the memory map and some of the photos in the docs, not every model had ROM in "Position 5". It looks like all did have 4 EPROMs installed. I have blanks and I have a burner. What's not up on Bitsavers is the 10T or 10C firmware. Does anyone have anything like that? It looks like the keyboard is both easy and not easy to remanufacture. It's a raw matrix, attached via fat round cable and DB25. The Keyboard includes a 74154 to decode 4 bits to 16 lines and the returns are via 8 lines. On the Terminal side, the 4 bits map to the 6502's A0-A3 and the return lines map to D0-D7 (it appears at $0000-$000F in the memory map). 91 keys, 1 IC and a lot of diodes would implement a keyboard, as would an AVR microcontroller sitting on the 12 row/column lines, translating to/from a modern keyboard. The video appears to be standard 15.575KHz 1.0-2.5V mono video plus H. Sync and V. Sync. routed off the board via the power supply connector (+5V @ 3A, +/-12V @ 0.4A and a smattering of -5V for the 2708s). So the only thing I would really need is copies of 4 or 5 EPROMs and I think I could get this working with a replacement display and reimplemented keyboard. Anyone happen to have the firmware? Thanks, -ethan

Vigra MMI-210 (VME DSP/audio card) documentation?

by cmhanson＠eschatologist.net

I just acquired a Vigra MMI-210 VME DSP/audio card that I?d like to get working. Does anyone happen to have manuals or know where I could find them? The Wayback Machine at the Internet Archive provides some programming information <https://web.archive.org/web/19970811215245/http://vigra.com/products/vme-au…> so if I can configure the card, I can make it do things. Unfortunately I have yet to find an installation guide. Since it?s a VME card, it has plenty of jumpers that will need to be properly set before it?ll actually work. Anyone have a source for more information, or another place to dig for it? -- Chris

PDP-8/E MM8-E jumper settings

by pete＠dunnington.plus.com

I've lost track of where the jumper settings are documented for the MM8-E, and I've got five sets here that have all been changed one way or another. Can anybody remind me where to find the settings for the three EMA jumper links on the G111? I want to set at least one board set to the lowest bank. -- Pete Pete Turnbull
