VAXen available, pickup only from Newmarket, UK

by shadoooo＠gmail.com

Hello Andreas, hello Adrian, I'm interested on all UNIBUS (and possibly QBUS boards) and also to VAX 2000. I'm ready to pay an amount (but I expect it should be in proportion with the weight). How much would you ask to pick and ship? Andreas: I can't reach you via direct email, please check your SPAM service and contact me! Thanks Waiting for acknowledgment. Thanks Andrea

teaching young IT certed person about old minis/mainframes

by tom_a_sparks＠yahoo.com.au

A question for the ones that work in the industry and are working with old mini and/or mainframes: How do you teach a young IT certed person about the old minis/mainframe that your department maintains?

PDP-11/23 Debugging

by jnc＠mercury.lcs.mit.edu

> From: Ben Sinclair > Thanks a lot for your help Noel! Sure, glad to help. I'm at just about this stage with my 11/23's, so it's no biggie. > I did write a Ruby program to enter programs in from files via ODT, so > I can probably run your test that way, assuming it's a set of addresses > and values. I can do that. Here you go (in Unix assembler, which is somewhat different >from the DEC one in some syntax details, notably '/' for comment, not ';'): br4 = 200 stack = 2000 conregs = 177560 rcsr = 0 rbuf = 2 tcsr = 4 tbuf = 6 rint = 100 . = 60^. conr; br4 / 1020 200 . = 1000^. test: mov $stack, sp / 12706 2000 mov $conregs, r1 / 12701 177560 / mov $rint, rcsr(r1) / 12761 100 0 mov $rint, (r1) / 12711 100 1: wait / 1 br 1b / 776 conr: movb rbuf(r1), tbuf(r1) / 116161 2 6 rti / 2 (The numbers on the right are hand-assembled octal, but I did put it through the assembler to make sure I'd gotten it right. The commented out instruction is clearer, but adds one word to the required type-in.) Here it is in address/location form: 60 1020 62 200 1000 12706 1002 2000 1004 12701 1006 177560 1010 12711 1012 100 1014 1 1016 776 1020 116161 1022 2 1024 6 1026 2 Start with "1000G" to ODT. It should echo everything you type, using interrupts from the console DL11 to do so. I did try this on my machine to debug it, and fixed one minor thinko (I had used "rts pc" instead of "rti"). After that, worked like it says on the tin. My machine is (at the moment) basically identical config to yours: an 11/23, a memory card (NatSemi), and a DLV11-J. (No terminator/ROM, it's in a Sigma box which has termination built in.) > That PDF is the one I was looking at OK. > though it looks like there are more diagnostics available for the 23+, > so that might not be completely equivalent to the test available for > the 23. Yes, that was my sense too. > I'm hoping a memory test shows that I have some problems there, which > is potentially the easiest thing to fix. Do you have a memory test, yet? I am planning on whipping up one of those too, for my own use, although it will be more elaborate than that console interrupt test. If you can use octal dumps to load, I can produce that form pretty easily: let me know what syntax your loader takes. > Someone told me a while back that the M8044 memory tends to be fail, so > maybe I should look for something else. Interesting; I have a whole stack, and the first one I tried seemed not to work. Noel

DELUA technical manual, VAX diagnostic

by RichA＠LivingComputerMuseum.org

We have a crumbling DELUA in the VAX-11/780-5 at LCM. There is a copy of the *User's* Manual at Bitsavers, but not the *Technical* Manual. Does anyone happen to have a copy lining the hamster cage floor, vel sim.? The User's Manual refers to a diagnostic, EVDYB, which "runs under the VAX diagnostic supervisor (VDS)." Does anyone here have either of those things, or pointers to them? In the mean time, I'm going to try to get the PDP-11/70 to run CZUAD from a simulated TU58, but I'm told that getting the DELUA into and out of the crowded Unibus backplane is an exercise in bloodletting.

WG: Re: VAXen available, pickup only from Newmarket, UK

by aswood＠t-online.de

Adrian and all listeners to this list, as promised I'd like to specify my interest more in detail. I'm esp. interested in the - VAX 7710, various processors + memory - AlphaServer GS60e - VAX 6610 and some of the smaller Alphas or all stuff fitting into the van. I'd take a 7,5t van to go from Germany to the UK to pick up these items. As in 2003, when I went with Fred (van Kempen) to London to pickup a large PDP11 systems at Zetter, I'm offering interested persons to accompany this trip to the UK. On the other hand I'd offer the possibility to pick up items into the van to carry these to continental Europe to be distributed to interested persons. Accompanying people, or for items to be carried to Continental Europe would have to share costs for the van and the ferry costs to the UK. @Adrian - what is the time frame for picking up these items?

PDP-11/23 Debugging

OK. Give me day or so, and I can whip up a really small test that you can toggle in to check out the interrupt on the console line. I won't be able to give it to you in a down-loadable format, alas: I'm working with a Unix (V6) toolkit, and at the moment I don't have the ability to produce DEC-format binary files, just Unix a.out. At MIT we did have a complete set of things for V6 Unix for doing DEC-compatible stuff (MACRO, LINKER, along with programs to convert back and forth between .REL and a.out format, and also to convert things to .LDA format), but at the moment the backup tapes I have which contain all that are in the process of being read, so there's no point to re-writing them all. > I've run a memory test program I found that's not part of XXDP, and I > believe it's fine, but is there a test in XXDP I could run? Sorry, I don't know anything about XXDP. Maybe someone else knows? > I don't see anything in the XXDP manual related to an M8044/MSV11. I'm not sure they'd have a MSV11-D-specific test program; it has no control registers or anything, so just a generic memory test is all you can do with it. > I moved all of the jumpers from my old M8186 to the new M8186.

Starting to sound like maybe a DLV11-J problem - or maybe the test wants something we don't know about? > I found the microfiche for the KDF-11B on Bitsavers, but they're > missing the one for the KDF-11A unfortunately! That might still be useful. I wanted to look at the -11B one, but I'm not sure I've found it; is this it: www.bitsavers.org/pdf/dec/pdp11/xxdp/fiche_200dpi/0170_CJKDJB0_1123B.pdf The KDF-11A and KDF-11B are _almost_ identical, programming-wise (they use the same chip-set) - the only differences I know of are that the -B has i) a built in LTC register, and ii) Bootstrap and Diagnostic registers. > I wish I had the microfiche for this CPU, as the one for the KDF-11B > lists the hardware requirements! Looking at that CJKDJB0_1123B thing, it does seem to want things specific to the -11B (e.g. it tries to test the second on-board serial line). If it's not a simple DLV11-J problem, I see dis-assembly in our future, sigh. Noel

Coleco Adam

by healyzh＠aracnet.com

After searching since the late-90's, in the last month I've finally had some real luck on the Coleco front. First I got a ColecoVision, and then this last Saturday I was able to get a Coleco Adam quite reasonably. In doing some research I've learned that I should be able to replace the printer with an Arcade power-supply that supplies +12V, +5V, and -5V. I also see that I can get a IDE/CF adapter that lets me use a CF card as a drive. Now for my questions, what software is available for the Adam that can make use of a CF card 'disk drive'? Also, I gather that the system will erase any magnetic media when turned on or off? What is it that actually does this, is it the power supply, cassette drive, or something else? Zane

Calling Philip Pemberton - UNIX PC/3b1 Emulator follow-up

by mediatransferfiles111＠gmail.com

Philip, I have studied the documentation on your work on your 3b1 emulator project. I am trying to rebuild a bootloader for a Convergent Technologies MightyFrame, and I have several working UNIX PCs that I am using for study, since they are similar...(by no means identical, but similar enough). You seem to have done some fantastic work on I see your posts on comp.sys.3b1 from 3+ years ago, and I am very impressed with your ability to decode the design of the UNIX PCs bootloader file. I was wondering if I could request some help with doing the same for our MightyFrame bootloader. I'd love to chat. I've sent a few emails to the address you provide on your 3b1 emulator site, as well as responded to your 3-year-old comp.sys.3b1 thread. Congratulations on some fantastic work, and I look forward to connecting with you. Sincerely, -AJ Palmgren http://MightyFrame.com ---------------------------------------- */usr/lib/iv/s4load.verbose* Download the s4load.verbose source code <http://6reoquestions.com/misc/MightyFrame/ATT7300/Files/s4load.verbose> Here Philip Pemberton discusses the code inside of s4load.verbose <https://groups.google.com/forum/#%21msg/comp.sys.3b1/VDPaYJCs0RM/dtXb5rVZ1F…> For reference, Philip is the author of a 3b1 emulator project <http://www.philpem.me.uk/code/3b1emu/>.

Visual Technology Visual 1050 site

by rich.bramante＠gmail.com

Thanks to Jay, the previously orphaned Visual 1050 information site has a new home on classiccmp: http://v1050.classiccmp.org. This is a repository for all the information I could find on this early-80's CP/M system including photos, documentation, source code, emulation instructions, etc. etc. Please take a look if interested and let me know if there's anything additional you can contribute. Thanks again Jay!
