Besides PUTR are there any tools for reading and writing to pdp8 OS8 device images? Something with source for Linux maybe?

DLC Company "Cowculator"

by aek＠bitsavers.org

I took a better picture of the panel for this yesterday http://bitsavers.org/pdf/dlcCompany/cowculator Other than a couple of want-ads from the early 60's I've not been able to turn up any more information on this. I'm assuming you optimize by adjusting the parameters to zero on the meter. Other than what is on the panel, I've not found anything on the DLC Company in Linthicum, Md.

Raised Floors

by mark＠matlockfamily.com

The discussion on raised floors in data centers reminded me of an interesting past experience. My company had installed its first supervisory process control system in an enzyme plant. The plant had been around for quite some time and the process control system was part of a retrofit of the facility. Part of that retrofit was remodeling a room for the PDP-11/44 and the related racks of industrial controllers. There were hundreds of cables carrying various analog and digital signals and control signals under the raised floor that they installed. The only bad thing about the location of the data center was that it was directly under some tanks that were installed on the roof. One tank was for concentrated sulfuric acid which was used to adjust pH in the fermenters. That acid tank was filled from tanker trucks that would come from time to time. One day a trucker who was filling the tank was not paying attention and over filled the roof tank and acid overflowed over onto the roof which should have held the overflow, but it was a flat roof designed to protect from rain not concentrated sulfuric acid. Down in the data center the operator noticed that liquid was flowing down the walls of the room and past the raised floor tiles into the space below. It was easy to confirm it was acid since it was attacking the paint on the wall. The acid pooled under the floor with the cables. That was when they called the research chemists next door. We came in and determined that there were some drains under the floor (it had been a factory room before it was converted) and we suggested that they flush the space under the floor with water to dilute the acid to get as much of it out as possible. Then they used fans to try to dry out the room and the space under the floor. After all this, miraculously everything seemed ok, but about once every 6 weeks or so that PDP-11/44 would develop some issue and the DEC field service guy (it was under contract) would come out and swap a board or two, marveling at how he had never seen boards that were so corroded. In retrospect I?m amazed that 11/44 survived as well as it did. Mark

9895A Flexible Disc Memory For Sale

by mark＠meba.com

I have an old floppy disk drive by Hewlett-Packard, their 9895A Flexible Disc Memory. We got this from an estate cleanout and I would like to sell it. It has been powered up and one bay door works when the button is pressed and the other doesn't. It is a large, very heavy machine. I have it on ebay for $299 ( <https://www.ebay.com/itm/254242280384> https://www.ebay.com/itm/254242280384) but that was just a shot in the dark. Any reasonable offer considered.

> On the LSI-11/2, with the machine stopped, 'run' was off, and the > output on AF1/AH1 was always high (i.e. not asserted). > I don't have any guesses as to what the behaviour of yours is about. Hah! Eureka! I had a brainwave, and decided to look at my machine with the serial console board pulled out! I then get the exact same behaviour on SRUN as you're seeing - a very brief spike every so often (about every 25 usec, here). So I'd be looking pretty hard at your DLV11-E; start by making sure it is configured correctly. Past that, you'll need prints; Manx claims there aren't any online, but there are a set in the jumbo assemblage, ET-LSI-11 (MP00706); the DLV11-E prints are on pp. 31-37. All you have to do to get a nice 'scope loop is to power the machine on; the CPU will dutifully try and read the RCSR, in a fairly tight loop. Probably worth picking up a spare DLV11 of some type for fault localization via board-swapping/etc; DLV11-J's can be found on eBait for not a large sum. Noel

Renting temporary local storage was a great idea; it would have been hard to get all that out of there on schedule any other way. (Alas, I don't know any hauliers who can help them get it all back to the UK!) They should have tried to get the raised floor too (I guess it wasn't included in the sale), since i) it'll be useful if they try and get the machine up and running, and ii) it'll probably just get scrapped.

M7264 Troubleshooting

by jnc＠mercury.lcs.mit.edu

> From: Glen Slick > According to the M7270 LSI-11/2 Microcomputer Module User's Guid[e], > it uses BC1, BD1, BE1, BF1 for SCLK3 H, SWMIB18 H, SWMIB19 H, SWMIB20 H. Oh, thanks! I wonder how I missed that, looking at the prints? (The drawings have these nice dark arrowheads to indicate backplane connections.) I just visually blew past it, I guess. BH1 is also used there (for SWMIB21 H); and on the previous page, the STOP L output is on AE1, and MTOE L (whatever that is) can be fed from AK1. Not quite sure how a Q22 memory card causes the problem, electrically, since those lines are inputs on the memory card, so it's an input<->input connection (i.e. voltage sources in TTL), but obviously it does. And I also don't see why Q18 cards are a problem; BDAL16 and 17 are AC1 and AD1 respectively, which I don't see in the 'extra pins' list for the LSI-11/2. Oh well, not too important to track it down. Thanks again for catching my miss! Wow, it's been a loooong time since I worked with an LSI-11 - about 40 years! :-) Noel

M7264 Troubleshooting

by jnc＠mercury.lcs.mit.edu

> From: Mister PDP Well, I verified that the LSI-11/2 should work in a Q22 backplane - in the sense that the only pins it tries to talk to are standard QBUS pins, and AF1/AH1 for SRUN. It doesn't drive BREF, which might cause issues in later QBUS systems. Although it's a different board from the LSI-11, it uses the same CPU chip set, so it should give us some useful comparison data. So after a certain amount of issues (see next), I got my LSI-11/2 working. (It doesn't seem to work with Q18 memory, such as the MSV11-D. Attempts to write 0 to memory from ODT wind up leaving the bits in the high byte set. I have no idea why - anyone have any ideas? With Q22 memory, the symptoms are even stranger; the system hangs with the 'run' light on - even with the HALT switch on! Luckily I had an MMV11, and it worked OK with that.) > I took a picture of the readouts for SRUN Odd. On the LSI-11/2, with the machine stopped, 'run' was off, and the output on AF1/AH1 was always high (i.e. not asserted). I don't have any guesses as to what the behaviour of yours is about. > Checking the BSYNC, it looks like there is life. It oscillates at > 58.605 KHz, and has wider peaks than the SRUN signal. The frequency is not as useful as plain timings - especially for signals which don't have a 50/50 duty cycle. For example, on the -11/2, while in the ODT console CSR read loop (below), BSYNC is asserted for 2.5 usec (which sounds about right for a complete read cycle), then off for 1.0 usec. Also, in the pictures, it's not clear which part of the cycle is asserted (which, on the QBUS, is 0V - i.e. inverted) and which is idle (~3V). Is this the actual bus signal we're seeing, with high being idle, zor on the other side of an inverting receiver? The image shows some timing numbers, but it's not clear that they mean. E.g. above, it says "4.00 usec" - but is that per division, the whole horizontal, what? Below, I see below "17.06 usec", and if that's the rising edge -> next rising edge interval, that sounds like a bus timeout is happening. > This signal does not respond to the Run/Halt switch being toggled, > but I would assume that to be normal Right; while in ODT the CPU is trying to read the console CSR, and so you should see BSYNC cycling. At this point, you might want to look at BRPLY, which will tell us if the console is responding to the read of the CSR. Also, I don't know if your /73 system has a KDJ11-A (dual width card, no onboard console) or a KDJ11-B (quad width card, onboard console); if the former, it might be worth swapping the DLV11 card into that system to see if _it_ is working.

But with a raised floor, you can whack the tile puller down in such a way that it makes an enormously loud pop that startles everyone in the datacenter! I cannot imagine difficult it would be to run S/360 era cables in overhead trays. Many are an inch or more in diameter. -- Will -- Will

Speaking of breezes, we found our plotter ( kept over-heating.) Some one kept closing the floor vent. We eventually found it was the plotter operator who was a young lady with a short skirt.

Looking for my old ADM-3A

by charlesmorris800＠centurytel.net

I used to have an ADM-3A Dumb Terminal... fixed it up, and made my own lower-case ROM from a 2716 EPROM and a lot of small wires. Sold it around 2005 or so, but can't remember who bought it. Anyway I'd like to buy it back if the current owner is out there and isn't using it :) Thanks Charles --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus

It's not necessarily good if the 4 clocks (I take it that's what the latter refers to) are working, because if one or more of those were broken, it's a relatively easy/simple fix, whereas if they are working, and the CPU's still not running, it could be a failed CPU chip, and the only fix there is to replace it. > the SRUN signal coming off of the backplane. Note that SRUN isn't crucial to the machine's operation, it's just user info. If SRUN is somehow broken on it's own (i.e. failed component somewhere between where the CPU generates it, and the display LED) finding and fixing that issue won't help. Far more useful, in terms of getting the thing running, would be to know if BSYNC on the QBUS is hopping around (as ODT tries to talk to the console - an easy thing to check into, too). If not, that's a show-stopper that needs to be looked into. > From: Glen Slick > the SRUN L signal is driven on to the backplane bus line AF1. The '78-'78 "microcomputer processors" says (pg. 3-15) that on the LSI-11 it's also on CH1; just to complete the complexity, it also says (pg. 3-32) that on the LSI-11/2 it's also on AH1! > From: Mister PDP > I hooked the oscilloscope up to SRUN off of E68, and found that it > oscillates low at 58.68KHz. .. Hitting the Run/Halt switch does not > have any effect on the period or amplitude of the oscillation. So maybe the CPU is actually running after all? Although turning RUN/HALT to 'HALT' should stop it - the Run light would I think go out when ODT is running. (It certainly does on the /23.) Can you check that BHALT on the QBUS is actually asserted (i.e. 0V) when the switch is in HALT? Noel

M7264 Troubleshooting

by vintagecomputersmn＠gmail.com

This is a continuation of my post from about a week and a half ago. The weekend I had some free time, so I returned, armed with a oscilloscope and logic analyzer, to try and figure out what is wrong with my H11A. At first, I tried to use the logic analyzer to confirm that the four clock signals on the MCP-1600 chipset were working properly. After a day of confusing and mixed up signals (I don't really use this type of equipment very often), I realized that my logic analyzer was picking up the signals incorrectly. I switched over to the oscilloscope and was able to see that the very basics of the CPU were working. After that, I decided to try and find out why the Run/Halt light was not coming on when I hit the switch. Looking at the H11 schematics, the light relies on the SRUN signal coming off of the backplane. The problem I am currently facing is I cannot find where the CPU board generates the SRUN signal. If anyone who is more experienced that me knows how the M7264 generates the SRUN signal, that would be wonderful. Thank You, Gavin

VT420 terminal screen

by petermallan＠gmail.com

I have a DEC VT420 terminal which works pretty well. However, I am concerned that sometimes the characters on the screen seem to get torn sideways and jump around a little on a timescale of less than one second. My guess is that there is some issue with the power supply, but that is just a guess. Does anyone have any experience of this and know what I should look at in order to fix it. If it never gets worse, I can live with it, but I fear that one day it will just die. Cheers Peter Allan

Tape seals?

by tshoppa＠wmata.com

Just a reminder: "Tape seal" is a generic name (or defunct trademark?) for the wrap-around plastic tape hanger for half-inch magtape reels. There's a flexible white (soft plastic) or beige (hard plastic) belt with a clamp (sometimes black) and a hanger. They usually had a little place to put a label in them too. They usually came with a new reel of tape but you could also buy them by themselves. 20 years ago I had thousands of 9-tracks hanging from decaying tape seals. Every couple days I would find a couple of tapes dropped to the floor and their tape seal broken. At the time it was no problem to find surplus tapes with recent tape seals to rehang them, and tape seals were still available new. Most of mine came from Southern California where I think the ozone in the atmosphere severely limited useful life of the plastics. Here in 2019 I only have a few dozen tapes and few remaining tape seals. I suspect any source I found of tape seals would be selling 20-year old tape seals. Is there any outfit that sells "new tape seals"? Or a preferred better way to hang tapes in 2019? It wouldn't surprise me if an archivist told me hanging tapes was the wrong way to store them but I never have really noticed (temperature/humidity changes seem to be a way bigger problem than storage orientation). P.S. Yes all these tapes were imaged decades ago. Not really sure why I still have them around unless say I need to boot a PDP-11 or VAX OS from 9-track which I guess hasn't happened in at least a decade for me. Tim N3QE

Hi Guys ?????? Well the RD53 in my 11/93 finally clapped out. ?????? The CPU is a late model KDJ11-E with everything on the one board. ?????? So its a switch from MFM to SCSI Drives. ?????? A CQD220A will drive the hard disk and the RQDX3 will stay to look after the RX50 ?????? I've? put the Hard Drive on the primary CSR address (17772150) and I will shift the RQDX3 to an alternate CSR ?????? Comments as to if this is the right way round and what CSR's to use for the two controllers invited. ????? Rod --

"industrial" PDP-11

From: Paul Anderson > They did make the RT100, RT340, etc. which were rugidized versions or > the VTs. We also ran into a VT52 (I think, although possibly it was a VT100) which apparently had been TEMPEST secured; the inside of the casing had been coated with a metallic film. (Or perhaps it was built to operate in an environment with a high E-M radiation level, and kept stuff out, not in.) I don't recall anything else about it now, alas - it's been almost 40 years! Noel

Kaur Collection Inventory

by athornton＠gmail.com

Last Saturday I went out to the location where the collection mentioned by Kristina Kaur resides, to take photos, create an inventory to the best of my abilities, and help her solicit proposals for the various items. I?m going to lead off with one of my last sentences in this email: PLEASE DO NOT WRITE KRISTINA, OR ME, DIRECTLY WITH YOUR OFFERS. Use the contact form in the Google Drive folder (see below) I?m pointing to and send your proposal to laura at rubinbernsteinlaw.com <mailto:laura at rubinbernsteinlaw.com> . I have no power over the disposition of any of this?I am just the chronicler?and Kristina wants to route all proposals for acquiring these things through the family's lawyer. The basic background is this: all of this stuff belongs to a man who has run a bulk-mailing business for many years, and who wrote a bunch of his own software for PDP-11 machines to do that bulk mailing. He has continued to use the PDP-11s until, apparently, quite recently. He also, unfortunately, has recently had a stroke, and although he is expected to recover, he is not going to be able to continue running the business, and particularly not from these machines. So his daughter, Kristina, has decided to make the collection available to people who will do right by it (preferably in a public museum), rather than just send it to the scrapper, which is awfully nice of her. I want to express my gratitude to Kristina for allowing me to go out there and root through the collection, and to Ruthann, who provided good company during the digging and invaluable service during the search. There are three locations for all these items. Computing equipment is either in a climate-controlled garage, and apparently has been running until quite recently, or it is in a warehouse, which I do not believe to be climate-controlled but is walled and roofed and kept dark, which are all good things in Tucson. All the manuals were on a bookshelf in the home office, and were kept climate-controlled and relatively dust-free. The manuals are in excellent shape considering their age, with no environmental damage, although some of them are clearly worn from use. Let me get a couple things out of the way first: it was rumored there was an 11/40 here. I didn?t see one, but I saw a mystery PDP-11 in the garage that I believe to be an 11/70. As near as I can tell, there are two PDP-11 systems in the garage (the mystery 70 and an 11/45), which I believe to be in running or near-to-it shape. There?s also a *lot* of stuff out in the warehouse, much of it apparently bought from the University of Arizona at auction over the years, largely shrinkwrapped (sometimes to pallets, sometimes not) or stored in plastic bags. My guess would be that the things in the garage were in general never used after their acquisition, although some may well have been migrated out there after their useful lifespan was over. This is a GUESS. I have no idea of the condition of any of it, or what was cannibalized as spares for other things; I can say that, in general, it?s been stored out of the weather and doesn?t seem to be water damaged or (for Tucson anyway) very dusty. I (and the Kaur family, and everyone) make NO GUARANTEE AT ALL of the condition of any of this. Everything here is sold WHERE IT IS and AS IT IS and it may or may not work or be restorable. It is YOUR responsibility to pick it up, and if it can?t reasonably be restored, tough luck. We don?t know, and the one man in the world who DID know is not in any condition at the moment to tell us. As you might expect from a bulk-mailing business, this collection is super-heavy on printers and various paper-handling devices, as well as tape drives. These are things I know almost nothing about: I have mostly collected 8-bit micros and videogame systems, and only recently have started acquiring and restoring DEC equipment. There may well be pictures of things Kristina doesn?t want to include as part of this lot?all the more modern printers and paper-handling stuff is destined for people in the printing-and-mailing world in Tucson. But there?s an awful lot of stuff here where ?uh, it looks like a lineprinter to me, and maybe you connect it to a PDP-11?? or ?that?s probably a disk drive?? or ?it?s a controller for _something_.? So among the things I?m asking you to do is to please help identify what I took pictures of. I?ll call out the things I find particularly interesting and baffling. I have already offered first pick of the manuals to Al Kossow and bitsavers.org <http://bitsavers.org/>, the Living Computer Museum and Labs, and Jason Scott at the Internet Archives, since that is likelier to get them scanned and preserved than if they just vanish into people?s private collections. The LCML has indicated interest, and I have not heard back yet from the other two. If there?s something from the manual collection you particularly want, and one of those three also wants it, you will probably have to work it out with them. Most of the manuals seem to be for fairly major software, which I suspect (but have not looked to check) that bitsavers already has a copy of. Kristina asks that you please put together a proposal for what you would like from the collection BY MAY 31, and please use the form on ?Equipment Proposal v2.docx? (https://drive.google.com/open?id=1oJFVg8MsTie3e3fpdzmfoWmIuQo96aQP <https://drive.google.com/open?id=1oJFVg8MsTie3e3fpdzmfoWmIuQo96aQP>) to do that. She and her family?s lawyers will evaluate the various received proposals and she will decide on a division of items. The pictures I took?and many of them are terrible. In many cases I don?t know what I was looking at, and in other cases, the items were not in convenient spots to photograph; sometimes both. All are in the folder at https://drive.google.com/open?id=1kECm7hiYComNDTrLEwPPKIdIZ3MqKJ6y <https://drive.google.com/open?id=1kECm7hiYComNDTrLEwPPKIdIZ3MqKJ6y> . My inventory of these things is in CSV form at https://drive.google.com/open?id=1Xv5aYu9tE3BUYZOicgJTTJhrDhy2ci89 <https://drive.google.com/open?id=1Xv5aYu9tE3BUYZOicgJTTJhrDhy2ci89> and in slightly-better-looking Numbers (a Mac spreadsheet) form at https://drive.google.com/open?id=15i1hEKjB108cq4g4B7c7gNpn-HDbgRIi <https://drive.google.com/open?id=15i1hEKjB108cq4g4B7c7gNpn-HDbgRIi> . I make no representation as to its accuracy?it?s just the best I could do in the time I had available. For most of the items, there is both a line number (some numbers are missing: this is intentional. They correspond to which spreadsheet line it is, and there are some blank ones) and a reference to the picture of said item, which is the filename (i.e. ?IMG_2xxx.JPG?) in the folder. I didn?t bother to do image IDs for the manuals?they are mostly in order, and I figure everyone can read, so matching the title to the image is generally straightforward. A few notes about the items. It looks to me?and I could be wrong?that there are two PDP-11 systems in the garage. One is obviously an 11/45, and judging from the structure of the panel, the other is some kind of 11/70, but I?ve never seen a front panel quite like this: https://drive.google.com/open?id=15i1hEKjB108cq4g4B7c7gNpn-HDbgRIi <https://drive.google.com/open?id=15i1hEKjB108cq4g4B7c7gNpn-HDbgRIi> . Based on the fact that there are two Datasystem 570s out in the warehouse, I suspect it?s a Datasystem with a Frankensteined front panel, but I don?t know. I think that basically it?s two two-cabinet systems, each with a CPU and a disk in one cabinet and a tape drive in the other cabinet, but again, I?m not sure. I have no idea whether the pair of Datasystem 570s in the warehouse are intact or not. There are also three VAXes out there, one 11/750 and two 11/730s. One of the 11/730s clearly has an attached RL02, but I don?t know about the other two. Most of the stuff out there, generally, looks like it?s in good shape in the sense that it was put in the warehouse, often in shrink-wrap, and not exposed to light or weather for a long time. Sometimes a very long time. I am quite curious about what the Sun Microsystems item (https://drive.google.com/open?id=1ZLpoP6ZoHfs3_dvdOFkv9uy68X29OSjV <https://drive.google.com/open?id=1ZLpoP6ZoHfs3_dvdOFkv9uy68X29OSjV>) is?I couldn?t really get to it, and it?s about the right size and shape for a 3/160, but it could also easily be something like a tape drive that Sun OEMed. It has a plate on it identifying it as part of an ?IRAF? system, and what I know about IRAF is that it?s astronomical software (I am helping design something that the LSST project hopes is a ubiquitous successor to it, sort of), and so I kinda suspect this came out of the astronomy department or Steward Observatory at UA. There are no pictures of the 13-or-so Decwriters in the warehouse: they?re on a shelf about 10 feet up and you?re going to need either a forklift to get them down, or be extraordinarily brave. The ADM-3A (well, I think. It?s obviously an ADM terminal, and these match my mental image of 3As, but I could be wrong about the model) was obviously the terminal of choice here and there are a dozen or so. Sorry about that, VT-xxx fans. Again: PLEASE DO NOT WRITE KRISTINA OR ME directly with your offers. Use the contact form and send your proposal to laura at rubinbernsteinlaw.com <mailto:laura at rubinbernsteinlaw.com> . I hope this is useful to folks. Adam

ISO Network General Sniffer 5.x manual set

by aek＠bitsavers.org

I've been working on archiving two Sniffers (ethernet and wan) and was wondering if anyone had a spare manual set. I have access to a set, but it is bound and would have to be scanned a page at a time

Kaur Collection Inventory

by jnc＠mercury.lcs.mit.edu

> From: Ed Cross > I saw a mystery PDP-11 in the garage that I believe to be an 11/70. Yeah, I think so; someone has transplanted a few red/purple toggles into it (perhaps some of the original blues got broken), but it's a /70 front panel, which won't (without major kludging/surgery) work on any other model. Without pictures of the insides of the main pull-out bay, and any others (there should be at least one, for the main memory) it's impossible to say how complete a system it is; -11/70 CPU boards are easy to find, though. > please help identify what I took pictures of. A couple of things I hoticed quickly: 2349 shows a PR05 high-speed paper tape reader (like the PC05, but reader-only), and 2325 a CR11 card reader (a Documation unit re-badged by DEC). My impression from looking at it all is that it's a huge pile of stuff, and some is probably just junk that should go to the scrappers. Their process, with the lawyer, is probably too top-heavy for a lot of the smaller items (e.g. 2387 shows a partial PDP-11 front panel which might be of some interest - e.g. I'd buy it if it showed up on eBait). Perhaps some one/group who is local can take everything that's left, after the main items (e.g. the VAX 750 - those are rare, I'm sure someone will scoop that up) are picked out, as a cheap lot, and sort out the good bits and put them up on eBait, and scrap the crap. > I hope this is useful to folks. Yes, very; thanks very much for putting in the effort. Noel

Kaur collection inventory

by athornton＠gmail.com

Last Saturday I went out to the location where the collection mentioned by Kristina Kaur resides, to take photos, create an inventory to the best of my abilities, and help her solicit proposals for the various items. I?m going to lead off with one of my last sentences in this email: PLEASE DO NOT WRITE KRISTINA, OR ME, DIRECTLY WITH YOUR OFFERS. Use the contact form in the Google Drive folder (see below) I?m pointing to and send your proposal to laura at rubinbernsteinlaw.com <mailto:laura at rubinbernsteinlaw.com> . I have no power over the disposition of any of this?I am just the chronicler?and Kristina wants to route all proposals for acquiring these things through the family's lawyer. The basic background is this: all of this stuff belongs to a man who has run a bulk-mailing business for many years, and who wrote a bunch of his own software for PDP-11 machines to do that bulk mailing. He has continued to use the PDP-11s until, apparently, quite recently. He also, unfortunately, has recently had a stroke, and although he is expected to recover, he is not going to be able to continue running the business, and particularly not from these machines. So his daughter, Kristina, has decided to make the collection available to people who will do right by it (preferably in a public museum), rather than just send it to the scrapper, which is awfully nice of her. I want to express my gratitude to Kristina for allowing me to go out there and root through the collection, and to Ruthann, who provided good company during the digging and invaluable service during the search. There are three locations for all these items. Computing equipment is either in a climate-controlled garage, and apparently has been running until quite recently, or it is in a warehouse, which I do not believe to be climate-controlled but is walled and roofed and kept dark, which are all good things in Tucson. All the manuals were on a bookshelf in the home office, and were kept climate-controlled and relatively dust-free. The manuals are in excellent shape considering their age, with no environmental damage, although some of them are clearly worn from use. Let me get a couple things out of the way first: it was rumored there was an 11/40 here. I didn?t see one, but I saw a mystery PDP-11 in the garage that I believe to be an 11/70. As near as I can tell, there are two PDP-11 systems in the garage (the mystery 70 and an 11/45), which I believe to be in running or near-to-it shape. There?s also a *lot* of stuff out in the warehouse, much of it apparently bought from the University of Arizona at auction over the years, largely shrinkwrapped (sometimes to pallets, sometimes not) or stored in plastic bags. My guess would be that the things in the garage were in general never used after their acquisition, although some may well have been migrated out there after their useful lifespan was over. This is a GUESS. I have no idea of the condition of any of it, or what was cannibalized as spares for other things; I can say that, in general, it?s been stored out of the weather and doesn?t seem to be water damaged or (for Tucson anyway) very dusty. I (and the Kaur family, and everyone) make NO GUARANTEE AT ALL of the condition of any of this. Everything here is sold WHERE IT IS and AS IT IS and it may or may not work or be restorable. It is YOUR responsibility to pick it up, and if it can?t reasonably be restored, tough luck. We don?t know, and the one man in the world who DID know is not in any condition at the moment to tell us. As you might expect from a bulk-mailing business, this collection is super-heavy on printers and various paper-handling devices, as well as tape drives. These are things I know almost nothing about: I have mostly collected 8-bit micros and videogame systems, and only recently have started acquiring and restoring DEC equipment. There may well be pictures of things Kristina doesn?t want to include as part of this lot?all the more modern printers and paper-handling stuff is destined for people in the printing-and-mailing world in Tucson. But there?s an awful lot of stuff here where ?uh, it looks like a lineprinter to me, and maybe you connect it to a PDP-11?? or ?that?s probably a disk drive?? or ?it?s a controller for _something_.? So among the things I?m asking you to do is to please help identify what I took pictures of. I?ll call out the things I find particularly interesting and baffling. I have already offered first pick of the manuals to Al Kossow and bitsavers.org <http://bitsavers.org/>, the Living Computer Museum and Labs, and Jason Scott at the Internet Archives, since that is likelier to get them scanned and preserved than if they just vanish into people?s private collections. The LCML has indicated interest, and I have not heard back yet from the other two. If there?s something from the manual collection you particularly want, and one of those three also wants it, you will probably have to work it out with them. Most of the manuals seem to be for fairly major software, which I suspect (but have not looked to check) that bitsavers already has a copy of. Kristina asks that you please put together a proposal for what you would like from the collection BY MAY 31, and please use the form on ?Equipment Proposal v2.docx? (https://drive.google.com/open?id=1oJFVg8MsTie3e3fpdzmfoWmIuQo96aQP <https://drive.google.com/open?id=1oJFVg8MsTie3e3fpdzmfoWmIuQo96aQP>) to do that. She and her family?s lawyers will evaluate the various received proposals and she will decide on a division of items. The pictures I took?and many of them are terrible. In many cases I don?t know what I was looking at, and in other cases, the items were not in convenient spots to photograph; sometimes both. All are in the folder at https://drive.google.com/open?id=1kECm7hiYComNDTrLEwPPKIdIZ3MqKJ6y <https://drive.google.com/open?id=1kECm7hiYComNDTrLEwPPKIdIZ3MqKJ6y> .

TeleVideo 1603 goodies

by pat＠vax11.net

I got some high resolution pictures posted of an early rev main board for the system, plus the front/back of unpopulated memory expansion and graphics boards for the system. Maybe someone else out there could find a use for that PCB artwork :) https://drive.google.com/open?id=1ILZ2UgwtfmoAtBMIYYIjaW4h5fKEPUYA Pat

Plessey disk drawing sets

by aek＠bitsavers.org

did anyone happen to get any of these? https://www.ebay.com/itm/VINTAGE-1979-PLESSEY-PERIPHERAL-SYSTEMS-MAINTENANC… they are different from the first set that I got for him, forgot about the auction, tried email and they say they are no longer available.

"industrial" PDP-11

DG One owners? I think I have something.

by shadoooo＠gmail.com

Hello, I have two DG One, they are however not identical. One is the older version, the other is more recent and have a different display. I never heard of a keypad accessory, it would be a very nice piece indeed! I should check for connectors on the back? Thanks Andrea
