Well, auctions like this are hopefully getting the word out that many of these old computers are worth a lot more than scrap value.

I think pretty much all that earliest generation of UNIBUS interfaces were stand-alone backplanes (i.e. 19" wide things that went in an H960 in a fixed location, and were filled with the small Flip Chip modules); the RK11-C, RP11-C, RF11, and TC11 all are. Partly correct. All early Unibus controllers which did DMA had their own backplanes. Which is why the NPR is obnoxious on the Unibus. Unlike the BR lines, the NPR is normally always just jumpered in the backplane, and located away from the BR lines. When DMA on single cards became more common, this became an obvious issue on the Unibus. You have to cut the wire on the backplane, and when you remove the card you either have to reinsert the write, or get the bug grant card that is double height, which also do the NPR jumper. But non-DMA controllers were single cards even back in the early days of the Unibus, like the DL-11. (Early DMA controllers were all multiple cards, so having their own dedicated backplanes were a pretty sane idea.)

I made a new OS/8 RL02 pack on vtserver (took the expected three hours at 9600 baud console speed). Booted up the 8/A, so far so good. But then Drive 0 faulted and OS/8 crashed... restarted and it crashed a few seconds later again. I flexed the middle of the RL8A upwards and the system worked. For a while. Then it crashed and wouldn't reboot. Back to where I was earlier in the week - won't even allow SerialDisk to boot if the RL8A is in the backplane. OS/8 on the SerialDisk virtual RK05 works flawlessly if the card is removed. Obviously there is still an intermittent which has come back. Maybe there's a tiny thread of something conductive stuck under one of the IC's and I managed to temporarily clear it as I described. Anyhow I am resuming my search for a good RL8A. I have wasted enough man-hours on this flaky board. If it works when you bend the card, I would suspect a bad connection, such as a cold solder. Of course, a short is also possible, but I wouldn't think that would do it. While tedious, it might work just to resolder all the components on the RL8A. The other thing to possibly look at is the bus connector. Check that there isn't some crap down in the slot. Have you tried the card in some other slot?

Re: Tu10 pdp11
> From: Johnny Billquist > Early DMA controllers were all multiple cards, so having their own > dedicated backplanes were a pretty sane idea. Well, there was also that large intermediate generation which still had their own backplanes, but they were 'system unit' (for lack of a defined term for this form factor) backplanes (e.g. RK11-D, RH11, etc), which fit into e.g. a BA11-K, along with other 'generic' UNIBUS backplanes (i.e. DD11-C, etc). That first generation I spoke of (the one with backplanes that mounted directly in H960's) are marked by the use of lots of small Flip Chip cards, not the larger quad/hex boards that one finds in the 'second generation' (above). I guess the larger board versions were cheaper to manufacture, which is why they got rid of the first generation ones in favour of the second generation (which were often functionally identical to the first-generation ones they replaced, e.g. RK11-C and -D). Those first-generation one used very similar construction technique to the KA10 generation of machines, which also used that size Flip Chip (although a different series, mostly with individual transistors), and heavier wire on the bacplanes. What did KI10's use, does anyone know? I have this bit set that they used roughly the same kind of Flip Chips as the 'first generation' PDP-11 DMA devices, but I've never seen a KI in person. Noel

Hm. Ok. Right. I was actually thinking along the lines of what you'd call the second generation then. However, it don't really make a difference. If the backplane is small, you can fit it in the same box as the rest of the machine. If not, you have it in its own cabinet. The principle is the same. You have a Unibus in, and a Unibus out. And everything in between is special for that controller. And you normally had this for things that did DMA. Simpler controllers usually fit into a single slot in a standard Unibus backplane. I actually used to play with an RP11 once upon a very long time ago, which was a full 19" cabinet of its own. Those first-generation one used very similar construction technique to the KA10 generation of machines, which also used that size Flip Chip (although a different series, mostly with individual transistors), and heavier wire on the bacplanes.

Mostek MK8022 QBUS memory repair tips
So I have one of these Mostek memory cards, and it was non-functional, and a Google didn't reveal _anything_ online about them. The fault was a couple of picked bits, so I started off tracing the signal paths for those bits from the bus fingers, to the transceivers, to an octal latch, etc - and then it dawned on me that this card has two banks (i.e. it has a 9x4 array of xx64 64Kx1 chips; i.e. to provide 16 bits wide plus byte parity, there are two groups of 18 chips), and one bank was picking, and the other was not. So that meant that data paths were all OK, it was a simple matter of finding some bad memory chips. (It turns out that diagnostic heuristic is quite useful, since many PDP-11 semiconductor memory cards have two banks of xxKx1 chips; so if you have dropped/picked bits, look to see if both banks have the same fault. If 'no', it's pretty much guaranteed to be a memory chip, and it should be easy to find. I just fixed for someone an M8044 with this failure mode, without doing any hardware debugging at all; the symptoms, and the prints, were all I needed.) There was nothing to indicate which banks/bits were where on the MK8022, but by pulling memory chips (luckily, they were socketed, so this was pretty painless), I managed to work it out (unlike many memory cards, it's not semi-random). For reference for others, here it is: Low bank: 01 - H1 ... 0200 - H8 0400 - E1 ... 010 - E8 High bank: 01 - F1 ... 0200 - F8 0400 - D1 ... 010 - D8 D-H9 seem to be parity. If anyone has one of these cards, and it's busted and they're not up to dealing with it, let me know. Depending on the failure mode, I _may_ be able to help (no documentation of any kind, after all...) Noel

There are so many aspects one can bring up. Some will show strong similarities, and others that make them look totally different. My point here was simply that controllers sitting in their own cabinets, made out of lots of small flip chips can be seen both on KA-10, KI-10, PDP-8 and PDP-11 systems from the late 60s, early 70s. Rather similar in concept. Usually also with lots of blinkenlights to show various information about the controller. (You just gotta love the "MAGIC" lamp of the KI-10.) (And I wouldn't be surprised to hear that the PDP-15 were similar, but since I have never seen one of those myself, I can't comment on them.)

MITS Altair 8800b switches needed
I am desperately seeking NOS, working pulls or accurate replacement switches for my MITS 8800b. These are flattened paddle switches, both ON-OFF and MOM-Off-MOM type. SPDT, Panel mount, solder post with a 15mm actuator. This last part is the pain as everything I've found is 10mm or less. I've checked every online source that I know of plus all of the local electronics and surplus shops with no luck. I'm sure someone here has a stash or knows someone who does. I need at least one of each type but would prefer a few more as I do have a few marginal switches to replace if I can. I'd even buy a complete 8800b D/C board if that's what it took. Please email me at my webmaster@ "vintage-computer.c0m" address if you can help.

I do have an M8192 and the Motorola 128KW Memory Board from that guy. The M8192 sometimes worked, sometimes not. After cooling with some spray in the xtal area I've checked the clock at the xtal and that was missing most time. The J11 worked on a KDJ11-DS, so I changed the Xtal. Bingo, it's running fine now. For the Motorola MMS1132...the board uses +5VB from the AV1 Pin which is my H278-A Backplane is not providing. I've soldered a bridge on the card between AA2 and AV1 (using the vias there) ..still not working and no ODT prompt. Found out that on the jumper pins near the QBUS connector (E28) two pairs are slightly bent, but no jumper on them. Looked closer to jims pictures (imsoldtoys.blogspot.de/2015/08/dec-boards-kdj11-2-kdf11-and-motorola.html) and found that 2 jumpers on my board are missing. Put the jumpers on them and now the board ist working at 0 (tested only with the memory address program from http://www.psych.usyd.edu.au/pdp-11/hints.html, after run 16 in R1). At the linked picture above the last jumper on E19 seems to be open, that's closed on my board originally, but this makes no difference at all, the board is working with both settings.

21MX proms (per request)
Several people asked, here's the scoop: The common proms for HP 21MX M/E/F are 1K, 4K, and 8K. 1K are used for either loader roms on the cpu board or microcode on the FAB 4K are used for microcode on the FAB or FEM 8K are used for microcode on the FEM The manuals you'll want to print and keep handy: HP 12992 Loader Roms Installation Manual, 12992-90001 (April '86) HP 1000 M/E/F-series Firmware Installation and Reference Manual, 12791-90001 (September, '83) I believe these are both on bitsavers. They are "must have" manuals. These are all bipolar proms, and most modern prom programmers will not be able to program them. I use a Data I/O 29B (with Unipak 2B), and it can program all these parts. Those programmers appear on ebay from time to time at around roughly $400. The blank proms are not terribly easy to find these days. Ebay has them occasionally, but your best bet is sites that cater to arcade machine repair. Here's a non-exhaustive but useful list of compatible parts for each: 1K parts MMI 6301 Harris 7611 Signetics N82S129 National 74S287 TI 24S10 AMD 27S21 Fujitsu 7114 (possibly 7052 as well, need to verify that) 4K parts Signetics N82S141 Harris 7641 MMI 6341 8K parts Signetics N82S181 Harris 7681 MMI 6381

I programmed at least one loader PROM using a BP Micro programmer. I forget exactly which PROM part I used. I probably have a very small number of blank PROMs left. I forget what loader PROM I swapped out and which one I swapped in.

Collection Reduction - Free for pickup
As a result of remodeling my house, I now have less space for the collection and need to thin it out a bit. The following items are free for pick-up in the Los Angeles area. Priority will be given to the first person who will take everything. Almost all of these are "portables" so it isn't that much volume. Some work; some don't and are projects. The Seequa (dual DOS-CP/M unit) and Access Matrix "Actrix" could be very cool pieces if brought into working condition. 1. Seequa Chameleon Plus: Powers up; no video - otherwise in nice condition 2. Corona ATP: Works, boots off floppy to MS-DOS 2.11 disc (included) - nice condition 3. Sanyo MBC-775: Powers up, no video; though external RCA video works - shows boot error in ROM - nice condition 4. Sanyo MBC-675: Works - missing one floppy drive - boots off floppy (not included) to MS-DOS 2.11, broken foot - rough condition 5. Access Matrix - Actrix: Powers up, video good, floppy drive B: cycles and won't boot (comes with case, manual and software) 6. Sony SMC-70G Genlocker: Works (tested RCA out), asks for system disk 7. NEC PowerMate Portable SX: powers up, no video, possible HDD crash based on screeching noise 8. Kaypro II: Lights flash on floppy drives, no video, constant beeping noise in sync with flashing floppy drive lights 9. Kaypro 2X: Works - boots to screen asking for disk (seem to recall that one of the floppy drives may need realignment) Please PM me if you are interested.

Re: MITS Altair 8800b switches needed
Since Erik brought it up.. I could also use a couple switches, but in my case they are for an 8800A model. (Well, it's sort-of a 'B' now as it was upgraded to the 'B' power supply, but it still has the original 'A' type D/C board). Like the 'B' it uses mostly Mom-Off-Mom mini-toggles, with panel mount bushing, and the long solder terminals that solder directly to the PCB (not the small eyelet type). But the handles are the standard mini-toggle bat handle - not the flatted paddles Erik describes. Any leads, feel free to mail me off-list.

In addition, you can yourself also see that your messages reached the list. If you do not get an answer, it is because people either do not have an answer, or else do not want to answer. Trying to offend them by being sarcastic will most likely not get you any more answers. However, it do show, to others reading, that you are pretty much expecting and demanding that people respond to your posts. Which is a rather child-like behavior. We are not here to satisfy your needs. Johnny, If you think we should fight over the same thing every time, please continue. This is exactly the same topic as in the port-vax list 2 or 3 years before. Otherwise (using your words): live with it. Im 52 years old (as you know) and already had my first heart attac last year so don't tell me that I sould behave more adult. Possibly I don't have so much time left that I can wait any time. Who knows how much time they have left. Does that make it ok to offend anyone else who is not responding to your every demand? I think not. You are free to disagree, but in that case I will definitely ignore you. What I have done? I was sarcastic, that was all. There where no insulting words in my mail. What I have reached with that? Besides of your opinion about my childishness, there where other answers that where at least interresting. (Thanks to Dave and Richard at this point, I've subscribed comp.os.vms in the meantime but think I meet the same people there) Let me live the rest of my time like a child playing with old computers, that's exactly why we are here; nothing else matters. I know that people trying to help, trust me, I'm doing that in other, cases with other people too and there are other people that pissing me off. But: I don't have a killfile. I do have a killfile. If people start offending me, or being generally obnoxious, I am obviously not going to change them, nor do I care enough to actually waste my time doing that. My time is precious enough to me as it is. So the obvious solution is to just ignore them from that point on. They can go on ranting about how unfair people are to them, and I do not have to read it. Johnny -- "When people start offending me.." ... read was I wrote and read again what you wrote. "I am obviously not going to change them" .. but this is exactly what you trying to do here. Sorry for being "obnoxious": My Answer to your answer in this thread was "Yes", accepting what our wrote to me, now the thing was done for me. I knew why I only wrote that. So from my point of view you don't wanted the discussion to be completed, so that seems to be your hobby. You are looking a little bit like an choleric from here, may be I'm the only one that feels like this. Besides of that I know that you are an clever fellow and you trying to help if you can. So if that aren't your shoes, why the heck your trying to wear them? About the killfile: I think I'm a "strong enough personality" so I don't think the computer should decide for me if I should read something or not. On the other side I'm trying to help people if I can, even if the pissed on my shoes in the past and sometimes enemies are turning into friends over time. No, don't need no killfile on my side. Don't get me wrong, that's no technical problem this time, we all get tons of spam mails and most of us have mechanisms to prevent spam from appearing in the inbox. I'm a small hosting company of my own and the usual mechanisms for that are installed an working, no problem to add folks there but I prefer deciding myself. Back to the topic: I think it where much more helpful to answer things like "Sorry don't know, never had todo with that", vs. simply saying nothing at all, leaving the man that looks for help alone. Maybe that's only my point of view, maybe not. about my intention: When I ask for help or opinions, I need that help or opinion, since I can't find a way tho clear the problem on my own. So Dave Wade isn't totally wrong with that what he thinks about my post. Maybe not "a cry of desperation" maybe more "helllo...is there anyone out there..?" .. Now, after that many text about "Role of Meaning" is it just me that thinks that the time where better to be used f
Re: PDP-8 diagnostics SR settings?
Johnny, I appreciate the thought, but there are over 1500 pins on this board and soldering them all would be a major undertaking in itself... I don't have a wave soldering machine ;) The first error flagged today is on D1 CA 3, the Command Register A bit 3. Scope loops definitely identify this bus as trouble and it's part of the disk address register too. The command register is two 'LS174 hex D-flops, and it drives the input of a '165 shift register (disk address) and the input of an 8234 (2-1 multiplexer/driver) back onto the data bus, and that's it. Should be simple... ha! The voltage on that output pin will go up and down as set by the loop until the board is flexed - then it will wander up to around 1-2 volts (measured at the pin with a DIP clip). However, I measured its ability to drive a 510 ohm load to 3.5 volts, and sink at least 10 ma (measured directly) staying below 0.8 volts. And the inputs to those two gates can be pulled to 0 with only a fraction of a milliamp, and go high when the driving D-flop is disconnected! I couldn't reproduce the problem while flexing the board either, but then I'd need three or four hands. So I changed the LS174 anyway. No luck - the card passes diagnostics until the board is flexed. All three of those chips are in the same general area of the board, too. Close inspection of the driven '165 shows a lot of black oxidation on its pins... don't those tend to grow crud inside the package and cause problems too? But... read on ;) After perusing the schematic several more times this evening, I found one more place I'd overlooked where D1 CA 3 (the "flaky" line) connects... to an AND gate E96 in the center of the card, that has a solderable jumper for RL01/02. I had moved that jumper to RL01 for testing by another member (as that is the drive he has), and back to RL02 when I got the card back from him. Lo and behold, underneath that piece of wire was a tiny solder whisker, at the moment shorting the CA 3 line to (something else?) but it was definitely continuity to another trace. Don't know how long that whisker might have been there, quite possibly from before I changed it for the test! Anyway I cleared it, and I've flexed the board numerous times while running AJRLAC controller diagnostic, and made 8 passes without an error. So far so good. So I connected the drives, booted up SerialDisk and can read their directories (only C & D, but that's a PIP version problem that I corrected on my RL02 image). Drives seem to be working :) ... of course R20A: (the SYS directory) is clobbered, so I'll have to remake the pack with my known-good image, but I was able to format the pack in Drive 1 without errors. Even wiggling the board several times. Now I'm running read/write tests (AJRLIA.DG) on Drive 1. No errors so far after two ten-minute passes :) THIS time maybe I really got it... CA 3 is the 4th bit of course where all the problems were occurring. Will let it run for a while longer. David Gesswein just sent me a version of dumprest for RL that he's just written, modified for my Omni-USB port at 40/41. If that works I'll be able to upload an entire RL02 in about 2 minutes instead of 3 hours with vtserver... -Charles

Most definitely, thanks to Jim Haynes for the foresight and energy to grab them when he could. Jim has been involved in the early discussions about the B5500 emulator back in 2011, he is one of the many that encouraged us to do the emulator.

It's not a CDC product--it was made by IPL Systems, Inc. and marketed by CDC and supplied with CDC peripherals. I don't know if the agreement yielded much in sales; by 1981, IPL was selling to end users under its own brand. Olivetti also sold IPL iron. Yet another of several IBM mainframe clone makers. --Chuck

What kind of keyboard is this?
I picked this up at Radio Shack about 25-30 years ago and have been hauling it around ever since. http://imgur.com/oNEcRFv,VacFqrY#0 (There should be two images...a link to the second.) It was a surplus thing that RS was selling on the parts wall and I grabbed on the off chance I'd need it someday. I lost the cardboard top to the plastic bag it came in, so I know nothing about it. Anyone have any idea? Thanks...Win
