Speaking of BIG printers, does anyone have the maintenance manual for the Centronics 101A impact printer? All that I've found thus far is marketing literature. Not even an owner's manual. -----Original Message----- From: cctalk [mailto:cctalk-bounces at classiccmp.org] On Behalf Of Mattis Lind via cctalk Sent: Sunday, August 12, 2018 5:08 AM To: General Discussion: On-Topic and Off-Topic Posts Subject: Oliverti Te300 teleprinter manuals?

Fairly Extensive Singer/Friden "System Ten" Computer System for Rescue

by rickb＠bensene.com

Through my Old Calculator Museum website, I have been contacted by a gentleman that has a fairly substantial Singer/Friden System 10 that is located in a building that the business wants to clear out. The computer system is slated to end up in a dumpster if it isn't rescued. The place the machine was stored is indoors, in an office-like space in a larger warehouse style building. The space was not temperature controlled, but there are no signs of water damage or serious corrosion. Some critters (probably mice) have been inside the cabinets of the system, but the contact said that there were no obvious signs that they chewed anything up. The system is very dusty (it was not covered), and it appears that some panels on the cabinets may have been removed, but are probably with the system. Some stuff appears to be partly disassembled. There also might be some spare parts, e.g., circuit boards. The system consists of a CPU, probably a Model 20, two Model 80 Display Terminals, a line printer of some sort, and two Mode 40 disk-pack (aka dishwasher-sized) disk drives. There are quite a few Model 41 disk packs there.. There also appears to be some documentation. There may also be some kind of magtape drive with the system, as there is a rack full of 7 or 9-track tapes hanging in it. Not sure if these are included with the system, though. Here is a link to some photos of the system: http://pail.bensene.com/Singer10 Beware that the web host does not have much upstream bandwidth, and the photos are pretty high resolution, so downloading them may take some time. Most of the photos are between 1.8 and 2.5 megabytes in size. there is some documentation on the Singer System Ten up on Bitsavers at http://bitsavers.org/pdf/singer/systemTen . Some of the documentation there is for the equipment that is available. These systems aren't very common, and there likely aren't all that many of them left in existence. Singer sold a lot of these systems into retail outlets as part of one of the first online Point-of-Sale systems. One notable account was Sears and Roebuck, who installed a huge networked (via Modem) environment using System Ten machines in stores to run Point-of-Sale systems, with modem links to larger systems that collected the information, and usually fed it to even larger systems (e.g., IBM mainframe) for inventory management, bookkeeping, and other large corporate-level reporting/management systems. However, the system aged quickly, as other competitors came onto the Point-of-Sale scene very quickly, with systems that were less expensive, more reliable, and more easily maintained. Many of the Singer systems in large retailers were replaced within a few years of being put into service. There was little market for "used" systems, so most all of them taken out of service went for scrap. The System 10 CPU was pretty unique in that it had "hardware"-based timesharing. The system managed time-slicing between "partitions" in main memory (magnetic core) with hardware that provided a fixed timeslice to each partition, switching to the next either when the time-slice ran out, or certain instructions (e.g., I/O) were executed that would trigger an immediate context switch. The system had hardware protection for the partitions to isolate the partitions from each other, allowing them to run independently. There was a shared and a read-only system partition which could facilitate inter-partition communications and management functions. Pretty cool for a design done in the late '60's. It'd be a real shame for this system to end up in the trash, which is exactly where it will go if a home can't be found for it relatively soon (e.g., next couple of weeks). The system is located in West Chicago, IL. It's all pretty sizable, so, you'd probably need a small commercial-style moving van with a lift-gate (the stuff is likely quite heavy, especially the disk drives) to haul it. You would also probably need a heavy-duty hand-truck or two, and some strong straps. You'd need some muscle, too. I suspect it'd be more than a 1-man job. My contact wants it out of there. You just have to come get it and haul it away. If you have any serious interest in rescuing this system, drop me an Email, and I'll put you in touch with my contact. Hopefully someone out there can give this machine a new home. Email: rickb .at. bensene .dot. com Rick Bensene The Old Calculator Museum http://oldcalculatormuseum.com

QED 933 (11/93 clone) and mystery SCSI board

by useddec＠gmail.com

I just found a QED 933. I've had Memtec boards before, but I don't remember anything about this one. The other board is a SI-QS 1000 6050-6005-B (Systems Industry?) quad height . Does anyone have any info or interest in these? Thanks, Paul

VCFMW drop offs, pick ups, visits

by useddec＠gmail.com

I'm looking forward to seeing everyone going to VCFMW. I'm going to try to go up Friday and leave late Saturday. It's always great when people swing by the house, but try to give me some warning, especially with me going up Friday. I hope to have a path dug into my last 25 foot storage unit and retrieve a ton of micro-Vax II parts along with a ton of other items. I still have a few 3000 alphas, about 10 3100s, a few 4000s, 5000s, 6 or so BA11-N (11/03L/23) boxes, BA23s, LA120s, and 1000's of other parts. Also some REMEX interfaces and a bunch of paper tape readers and maybe punches I'm getting tired of looking at. Please contact me off list if you have any requests or questions. Feel free to send me wish lists. Thanks, Paul

VCF Midwest seller's experience?

by marvin＠west.net

This will make my third year selling at VCFMW. My motives are to pay for the trip :), Diminish the "collection", and have fun talking/meeting with other attendees. All three have been easily accomplished! For me, I don't relish the use of a consignment area and spend most of my time in the selling area. I try not to buy much as I am really trying to downsize the collection. I do find it better to try and have buyers waiting for anything large or heavy. I'm not sure, but I suspect enough people might be interested that it could be a 24 hour event, Fri night - Sun afternoon :). See you there!

VCF Midwest seller's experience?

by jfoust＠threedee.com

I'm thinking of reducing my collection by bringing items to VCF Midwest. I attended once six or seven years ago. Of course a great deal depends on what I'm selling, so I'll build a list. Possibles include Micro PDP-11, Microvax II, Vaxstations, Kaypro 1, CBM, Amiga, Atari, Apple, some S-100 boards. Is there anyone here who sold at a previous VCF Midwest? How did it go? If there's only 150 attendees, is selling more like exhibiting? Ideally I'd like to come home with an empty van. - John
