DS3100 Questions

by cmcmanis＠mcmanis.com

I gave the DECStation 3100 to a fellow caretaker and he had some questions I thought I would bring up here to see if there were any easy answers: 1) Is the display adapter on the main board of the DS3100 always monochrome? 2) I found Bruce Lane's description of making a color cable for the 15 pin connector but not the equivalent idea for a monochrome connector. 3) Does anyone have a spare cable? 4) What monitor works with this system? --Chuck

More OS wants....

by peter.pachla＠wintermute.org.uk

While I'm thinking about it.... Would anyone (again in the UK) know where I can get a set of (presumably) Microsoft XENIX installation discs for my Jarrogate "Sprite"? Mine came with both CDOS and XENIX installed, but I only got the discs and manuals for CDOS. Also, I've been playing with "Concurrent DOS XM" on a '286 for a few years on and off, but I don't really have the right hardware to run it effectively. So, can anyone please help me out with a compatible EEMS board (AST RAMpage! or RAMpage! 286 AFAIK) or even a copy of Concurrent DOS 386? TTFN - Pete. -- Hardware & Software Engineer. Sound Engineer.

Looking for IBM Xenix

by peter.pachla＠wintermute.org.uk

Hi, sorry not to have been posting here lately but things have been very hectic with both of my parents being hospitalised. :-( To be brief I'm looking for a copy of IBM Xenix v2.00 to have a play with on my XT-286. Anyone here in the UK able to help, preferably I need a copy WITH the manuals.... *PLEASE* respond directly rather than via the list, although I'm still receiving it I don't have time to read the messages at the moment (it's been nearly two weeks since I have).

I can tell you only that there are spaces in the CPU backplane for two 4K stacks. The MM8I's _might_ be 8K each. The standard stack for the -8/i and -8/L is 4K. I am not aware of any larger ones.

Wanted: Old DEC stuff in Texas

by mrbill＠mrbill.net

Anybody out there within a reasonable driving distance (6 hours?) of Austin, Texas that has any old DEC gear they'd like to get rid of to a good home? I've got a two-car garage thats finished out with carpet and paneling, and I'd like to start that collection of DEC stuff I always wanted. I'm looking for VT1xx/2xx/3xx terminals, MicroVAX/ VAX equipment, PDP-11 (especially) gear, etc. Stuff I've got for sale or trade or donation if you need it bad enough: Six 1200 watter power supplies for a Sun 4/690MP Six 2.1gig SCSI differential FH 5.25" HDs from a 4/690MP Six 1.3gig IPI 5.25" FH HDs from a 4/690MP 16-slot VME cardcage/backplane/blower assembly from a Sun 4/690MP Five 4/330 / 4/630MP deskside VME chassis One SCSI drive shelf and two IPI drive shelves/trays (with slide rails) for a 19" rack Two IBM POWERServer 530 RS/6000 servers, each with 64mb RAM, 2.3gig Exabyte tape drives, one with CD-ROM and 1gig HD, both with IBM 3151 amber terminals. AIX 4.1.3 loaded, with AIX on CD-ROM included. Other stuff like a 16-port serial breakout box, etc. Couple of Toshiba laptops with the orange plasma screen (not sure about the models, I think one's a 3100 and one a 5100; I used them for serial terminals) If anybody's interested in any of this equipment, please let me know. I'd love to see it go to a good home where someone cna get some use out of it, and possibly get something for me to play with in return.

Xerox D-series workstations

by schoedel＠kw.igs.net

Hello all, I've just been fortunate enough to obtain a pair or Xerox D-series machines. One is a 53D (Daybreak? Dove? 6085? 1186?) and the other an 8010. I understand the 53D has its microcode control store in RAM; is there any available information on the microinstruction encoding, and how I might in principle be able to write my own? (I work for a company that did microcode compilers, ten years ago when people still built microcoded machines, so yes, I *do* know what I'm suggesting.) For that matter, is there any available information on the macroinstruction set(s)? So far I've been able to find very little about these boxes. The 53D boots happily into Lisp. Err... could someone please tell me, as soon as possible, how to safely shut this machine off? Two boxes of Lisp manuals, dated June 1997, and still shrink-wrapped. If there is a 'collector' out there who would like to trade for 'working' copies of the same, contact me before I open them.... A carton of Lisp floppies; although these were sold with the 8010, they clearly belong to the 53D, since they're 5.25" not 8". They're marked DS/DD 48tpi; is there anything unusual about these, or could they in principle be read and archived from a current pc? The 8010 doesn't boot. The power supply is fine; the drive spins up and is loud but sounds smooth. The LEDs rest at 0000, and nothing happens. Any obvious things I should try, or will I have to wait until I can do Serious Work on this? -- Kevin Schoedel schoedel(a)kw.igs.net

Tandy 2000

by jrice＠texoma.net

I was given a Tandy 2000 recently. Due to the death of my mother this week I just tried to boot it. It puts the 256k memeory message on the screen and the floppy drive light comes on but it never seems to boot. I recieved a boot disk copy with the machine and have ordered a MSDOS/Basic boot disk from RSU but no resultds. Any common prblem I should look for? I've already reversed the floppy drives with the same results.

Priority for a QDSS color framebuffer?

by mbg＠world.std.com

>Where is the color frame buffer normally placed relative to everything >else in a Vaxstation II/GPX ? (everything else being defined as ethernet, >TQK70, disk, and async muxes) According to the Vaxstation II/GPX hardware manual, the correct sequence of boards is: 1) CPU 2) Memory 3) Ethernet interface 4) VCB02 base 5) VCB02 memory 6) VCB02 memory 7) Async comm (DZQ) 8) Asyn multiplexor (DHV) 9) Sync Comm (DMV) 10) Disk controller (RQDX3) 11) Tape controller (TQK50) But I have always placed the disk controller after the ethernet interface and before the VCB02... it puts the controller electrically closer to the CPU, which should make disk I/O a little faster (I know, almost infinitesimal, but the delay has got to be measurable, and adds up over time).

Just picked up a HUGE PDP-8I and PDP-15 and .....

by dylanb＠sympatico.ca

Here is what I picked up: (lot of questions); PDP-8I (came from a former Dec employee): This mini is loaded. (I am really tired and have not had a chance to look at it all but..): It came in two racks. The first rack contained the 8I with high speed paper tape, and a DF32. The second rack had 4 core memory expanders (MM8I), an AX08, an Oscilloscope interface, and a REALLY COOL NEGIBUS 8" floppy drive that emulates 2-4 DF32s. The second rack is a "LAB-8" config. I got all the manuals (for every part), maintenance docs, "D" size prints, heaps of OS/8 stuff, TSS/8, and disk monitor. The system came with 12 trays of paper tape. I have no idea how much core is in the CPU as I have not pulled it out. In the prints I saw it has "EAE" and some other options... Oh,oh, and I got at least 30 negibus cables :-) PDP-15 This unit came in 3 racks. The first rack is the CPU/control panel with: high speed paper tape, mag tape, and a "blinky light panel on the top". The second rack is the CPU and power supply. The third rack contains a large drum memory unit and interface. The CPU has two large core planes. I don't know if there are any more hidden anywhere. This unit is large and came with 6 large boxes of documentation, schematics, maintenance manuals... Software wise it has a lot more than I expected... 45 trays of paper tape. I was told MUMPS was on it/with it? I have not looked at the paper tapes yet. Bought boxes of spare boards: I also bought 10 large boxes of PDP 11, PDP 8, and other digital peripheral/CPU cards. I will compile a list in case anyone needs anything I am not keeping. I also picked up 15-20 boxes of brand new boards from dec/third party still wrapped... no idea what they are yet. Bought a large box of Nova core memory/FPU I picked up around 10 core memory planes and tons of Nova 2/3 spares. I got a lot more Flip Chips and another H901 blue flip chip patch panel. I will take a picture when I can but these systems are taking up my families hallway, living room and dining room at the moment so I have to clean out more of my lab and roll the stuff in. Basically, I bought everything but the PDP 11/34 that was left there. I hope to have the 8I running early next week (looks like it is plug and play). Questions: 1. How much memory is inside the 8I and what was the stack size, how much expansion is the MM8Ia s? 2. Does drum memory crash when you cycle the power? 3. I found a board made by digital that says "CMOS-8" (memory),, what model PDP-8 does this work on? 4. Anything "bugs" I should watch out for before powering up the 8I or the PDP-15? Thanks john...

Hi I'm passing this along in case someone on the list can help this fellow: Date: Wed, 03 Nov 1999 10:04:50 +0100 From: Stephan Slabihoud stephannews1(a)slabihoud.de Hi, I am looking for scans of homecomputer mainboards of the 70ths and 80ths. These scans I would like to add to my computing museum (<A HREF="http://www.8bit-museum.de)">http://www.8bit-museum.de)</A>. Unfortunately a lot of scans are not available yet: No scan available: :-( Acorn, Amstrad, Coleco, Dragon, EACA, Enterprise, Excidy, Jupiter, Luxor, Mattel, NeXT, Osborne, Sharp, Spectravideo, Tandy, Tatung, Camputers and Exelvision A few scans available: :-) Apple (Apple I), Atari (2600 black, 800XL), Commodore (8032, VC20, C64, C64C, C116, C16, P/4), MITS (8800), Oric (1, Atmos, Telestrat), Sinclair (MK14, ZX80/81, Spectrum Issue 1+2, QL), Texas (99/4A), VTech (Laser 500) Some of the scans are not very good and I will be pleased to replace them by better ones. Who wants to help me but does not know how to make a scan or photo of the mainboard can ask for my advice. :-) A picture should not exceed 800 KByte (JPG medium). Thanx very much Stephan Slabihoud

HP 9144 and HP tapes: Again

by rigdonj＠intellistar.net

I just got back from another hamfest. The only interesting computer stuff that I scored was two dozen new HP tapes. In the box are some that are marked "(for use with the HP9142)". This is the first time that I've seen tapes for the 9142. They have part number 92242L for the long ones (600 ft.) and part number 92242S for the long ones (150 ft.) These are not usable in the 9144 or 9145 tape drives. Joe

Needed, Memory chip info for a Compaq

by edick＠idcomm.com

There were two types of SIMMs, initially. The ones with equal numbers of devices on both sides were viewed in some systems as being two SIMMs, but occupying a single site. I had one motherboard which required you jumper it differently for the double-sided variety than for the single-sided. Now, some of the single-sided SIMM had the parity chips on the reverse side, but were still thought/spoken of as single-sided. You might do well scrounging around an electronics graveyard (landfill). I've left bunches of them lying there while diving for pearls.

For those that don't know, Tru64 is the what used to be called DEC Unix, which in turn used to be called OSF/1. Friday evening Compaq announced/release a Hobbyist version. It's $99.00 for a copy, I don't know what licenses are included. Please note, this doesn't run on VAXen, but it does run on most Alpha's with 64MB+ RAM and 1GB+ Hard Drive space. http://www.unix.digital.com/webadvisory/ http://www.unix.digital.com/noncommercial-unix/ Personally, I might get it, but the system that is running UNIX right now is going to continue to run OpenBSD.

Experience with Dilog DQ696-20?

by CLASSICCMP＠trailing-edge.com

>Anyone have any experience with the Dilog DQ696 ESDI disk controllers? I >just installed one in a MicroVAX III and I've been getting really _dismal_ >performance out of it. I had it misterminated for a bit (the middle drive >(of two) was terminated rather than the end drive). But I fixed that >without any increase in performance. The format/block analysis took about >10 hours for a 600MB disk. > >The interleave was set to 1 but that seems pretty standard these days, >should I up it to 2 or 3? or perhaps reduce it to 0? > >The drives are Micropolis 1568's so they're nice fast drives. Were these 1568's used previously on this Dilog controller? If not, they're probably configured for use on a PC-clone, and have the sector length set on the "short" side. The PLO in the Dilog isn't locking onto successive blocks, and as a result it's reading only one sector per revolution. The cure is to set the sector length on the 1568's to be a bit longer. You'll lose a little bit of capacity (and will have to reformat), but it'll be able to read more than one sector per revolution. Setting the interleave can interact with this, of course. If you don't know how to alter the block length on your drives, try altering the interleave and see if that helps any. > How about >Q-bus priority? No, if things are slow with the controller running the built-in exerciser (which *don't* move disk data over the Q-bus) it's not a Q-bus problem. It's a drive problem. -- Tim Shoppa Email: shoppa(a)trailing-edge.com Trailing Edge Technology WWW: http://www.trailing-edge.com/ 7328 Bradley Blvd Voice: 301-767-5917 Bethesda, MD, USA 20817 Fax: 301-767-5927

11/34 inventory - board list

by cmcmanis＠freegate.com

So this is what is stuck in the 11/34 I got: Backplane #1 (working from right to left as seen from the front) M8266 (6) M8265 (6) M8267 (6) M7859 (4) M9312 (2) M7896 (6) M7856 (4) M7228 (4) M920 (2) ** bus jumper ** Backplane #2 M7800 (4) M7800 (4) M7860 (4) M7860 (4) M7892 (4) Dual D/A converters (third party) (6) Grant card M8716 (4) M9202 (2) ** bus jumper ** Backplane #3 M7219 (4) M7821 (3?) M796 (1) (hidden) (2) M9760 (2) M9302 (2) In this last back plane there are several cards that are dual or one wide and are short with white extension things over them so that they can be pushed from the top (but they hide the M numbers) So it seems that this is actually an 11/34a on the inside, that's nice to know. Anyone have any clues on the third backplane? --Chuck

Tennecomp Systems TP-000020B - What is it?

by wirehead＠retrocomputing.com

Looking at some of the inventorying of an 11/34 inspired me to look inside my 11/34a again. It has a board labelled -> Tennecomp Systems TP-000020B Anyone know what this board is or what kinds of boards Tennecomp made? I did a search on the Net and only found a resume of someone who worked there. If nobody here knows, maybe I'll send her an email (but she looked like a production manager not an engineering type) and see if she can tell me what sorts of things they made. Thanks... Wirehead

Looking for Intel's 8008 programming tools: PL/M, Assembler, Simulator

by jlewczyk＠his.com

Hi All, I am looking for Intel's programming tools for the 8008 microprocessor. These were written in Fortran and consisted of: An assembler A simulator A PL/M compiler Any information on these tools would be appreciated! An original tape, card deck, listing, would be great to find, but a copy of any or all of those would be acceptable! The PL/M compiler and 8008 Similator were written by the late Gary Kildall (of CP/M fame) for Intel. Thanks! jlewczyk(a)his.com

OT: Microsoft Ruling is finally out!

by healyzh＠aracnet.com

Guity! http://www.zdnet.com/zdnn/special/msdojendgame.html I found this elsewhere, I think this sums it up nicely. "Microsoft has demonstrated that it will use its prodigious market power and immense profits to harm any firm that insists on pursuing initiatives that could intensify competition against one of Microsoft's core products," Jackson wrote in his findings. "The ultimate result is that some innovations that would truly benefit consumers never occur for the sole reason that they do not coincide with Microsoft's self-interest." Something tells me that this is going to help Caldera's case against Microsoft! Zane | Zane H.

Shipping old heavy stuff

I've heard that many coin-op video game collectors like to use Forward Air. The last I heard, they charge $28.50 per 100. But it's primarily an airport to airport transport service.

I may be getting my 1800 pound computer from Indiana this month. A friend made a deal with a car collector that has his own enclosed car van.

Here's how to guess; it depends on the tape having been properly rewound before ejection. But as you might have guessed, it's hard to get the HP drives to let go of a tape 'til they're darn good and ready and that means rewound. Hold the tape so you're looking at the clear plastic side with the capstan roller at the top. Which reel has (almost) all of the tape on it? Left -> HP tape, right -> non-HP. -Frank McConnell

Cleaning an 11/34?

I would suggest vacuuming as much as possible before even pulling the boards -- especially the deteriorating foam... try to orient the box such that any foam which breaks off while you're doing this doesn't fall into the backplane...

Sounds good.. One problem is that you have to keep in mind the slots which might need the CA1-CB1 jumper installed if you don't have boards in it... otherwise you may get bus errors... I would also think about a PSU power-on test with no backplanes attached, then with backplanes attached, then with Unibus jumpers, etc... I don't know if the PSU can handle a no-load condition, though -- Allison, Tony or Tim.S might be able to answer that better.

That's all the point of the discussion. That's why raw numbers tend to be meaningless. That's why system designers nowadays make decisions based on simulations and not on raw specs. Carlos.

BYPASS does just that: bypasses all UIC-based checking - reads, writes, deletes, etc. It's handy when you need to delete a directory tree, but it's a dangerous one to leave on by default. My typical scheme is to leave BYPASS _disabled_ for the SYSTEM account asa default priv. CMKRNL allows your process to execute a "change mode to kernel" call, which allows you to read and write physical memory. With this priv, a malicious programmer can write code to peek at the process headers of other processes on the system (like a "who" command would) or even tweak their own header bits, possibly granting themselves permissions or changing their effective user name. I used to have programs in C and FORTRAN to do all these things, but they only work on pre-VMS-5 releases (and I didn't write them; I inherited them when I took over a VAX-11/750 w/Fuji Eagle, running VMS 4.2 about 13 years ago). -ethan ===== Infinet has been sold.

HP 9144 tapes

by rigdonj＠intellistar.net

I went and looked up the HP part number for the 9144 tapes. It's "HP 88140LC" for the 65 Mb ones and "HP 88140SC" for the 15 Mb ones. Joe

Finally got a "straight" DF32 yesterday

by dylanb＠sympatico.ca

Okay, I have the same drive(s-this weekend). The switch allows you to select one of three computers the drive will be used on: Straight 8 PDP-8/S PDP-8I the switch controls bus lines, (and selectors diode or resistor) logic for: pcl - straight 8 init - for 8i certain bus signals for 8/8s/8i, and other things I am finding in the schematic (mentioned changes between 8,8I,8/s). I haven't read the whole book yet as I have been inundated with documentation again... and my pick up this weekend will make my current document set look like a pamphlet. Do you have schematics? Contact me off the list. P.S. They did not put this switch on early model DF32s as only the 8,8/S was around. I am getting a newer drive that has the 8I switch (more changes). Does anyone know if digital fixed the head crashing problem with the DF32-D, or -F?
