Previously I only had the preproduction code listed in a US patent. I'm not sure when I'll have time to actually work on the simulation, though. My original plan had been to crack open an HP-01 module and try to read the ROM bits optically, as Peter Monta did for the HP-35. However, that didn't work, probably due to a passivation coating on the ROM dies.

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

11/93 Rebuild

by rodsmallwood52＠btinternet.com

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

by jnc＠mercury.lcs.mit.edu

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
