ISO: PDP-11/40 LTC and Stack Limit options

by jnc＠mercury.lcs.mit.edu

> From: Josh Dersch derschjo at gmail.com > see if the same is true for other bus grants -- I can run the system > with no grant continuity card at all in slot 9 and everything works. Well, the BG4-BG7 grants definitely _are_ run through the SPC slot 9 (see below) - at least, on a stock system. It's _possible_ that the software you're loading doesn't use interrupts. (I have this vague memory that, unlike the -11/34, the /40 doesn't complain if there's a non-continuous grant line.) Or perhaps someone wired them across on that slot, to avoid knuckle-mashing trying to put a G727 down there. Anyway, the wire list in the drawings show all four lines (although they are listed in two places, under "BGx" and "BUS BGx"). E.g. BG4 is shown on pg. 79 as going from D07E2 (Source - K4-6, pg. 63, top right) to D09S2 (which is the correct BG4 'in' pin for SPC), and as BUS BG4 on pg. 84 as going from D09T2 (SPC BG4 'out' pin) to B09E2 (correct BG4 UNIBUS 'out' pin). > I now have the system booting XXDP Yahh!! > I did find out why there was that wire missing on the backplane; the > KW11-L requires a wire (carrying one of the bus grant signals) be > removed from slot 3. Right, BG6 is wired through that KW11-L slot because the clock needs interrupts - the wire list shows that on pg. 79, where the BG6 entry is longer than the other BGn entries, because of that. If I'm reading the notations correctly, it shows the jumper installed by default - I guess it was removed by hand on systems sold with a KW11-L? There must also be some way to indicate that the jumper should be wired on top at both ends (so the F03V2 to D09M2 wire wouldn't have to be removed to pull the F03R2 to F03V2 jumper) - although maybe they just did _all_ multi-pin runs as alternating low on both ends, high on both ends, repeat to make removal/replacement easier. Speaking of notation, dunno if you knew this (I didn't), but the wire list for the 11/40 includes etch also; you can tell etch entries from an 'H' in the "Q" column and 'P' in the "Remark" column. Don't confuse them with the 'H' in the "A/P" column, which also also has some 'L' entries; not sure what that is about, unless it tells whether the signal is asserted high or low. Noel

for sale/trade: big list of both old and (relatively) new, deadline: end of November (ideally)

by mgariboldi＠gmail.com

The following is for sale, or trade possibly. (I've tried to send this earlier, but it didn't appear in the list, so this is my second try to post this...) Most of the listed items I've used together with SGI IRIX and HP/Compaq/DEC OpenVMS and Digital/Tru64 UNIX systems and served me very well. I need to sell this by the end of the month (Nov-2016), else I'll have to potentially scrap a considerable bunch of it. I probably forgot to mention a number of things and perhaps I made a few mistakes here and there. I'll try to update (and if needed, correct) this list with follow-up posts. For now, this is the list of items: - SGI systems, e.g. MIPS R5000 and R5200 processor equipped O2s notably, perhaps also a teal Indigo? with 250-MHz R4400, at least 256 Mbytes (also up to 1 Gbyte available) of RAM, various types of CPUs available, along with various other options in terms of disks, video I/O, etc. (ask me) --> suggestion: if you don't care for IRIX, an O2 would still make an excellent X terminal to any e.g. other system, too, as they don't consume a lot of power and they're wonderfully small; - SGI parts, like an SGI Tezro dual-processor 700-MHz R16000 system board and an SGI DMediaPro DM10 IEEE-1394a FireWire PCI card plus cable and manual; - DEC Multia/UDB VX40B, maximized, with 166-MHz LCA4/21066 processor, the maximum amount of RAM (256 Mbytes), large 73.4-Gbyte 2?" SCSI HDD (with Tru64 UNIX V5.1B[-5?] optionally pre-installed, OpenVMS V7.2 also works on it, the original vertical stand and documents are present, too), Ensoniq AudioPCI (16-bit 48-KHz) audio card, replacement NVRAM/TOY back-up battery, experimental SRM console, PCI audio card and custom-shoehorned, etc.; - various older/non-x86 or compatible computer (besides earlier mentioned SGI, e.g. DEC, Compaq and HP) bits & parts, think of FireWire (e.g. IEEE-1394a), audio, etc. cards, cables and such ... included are things like an AlphaServer DS15-compatible PCI audio card, HP IEEE-1394a FireWire PCI card (rare, should work in some HP Integrity systems) and more (ask me for details); - Exar/Neterion/S2io 10-Gbit fiber-optical (10GBASE-SR) PCI-X Ethernet NICs including transceivers, besides x86/-64 also OpenVMS and IRIX compatible (and tried/used in various systems, including HP rx2600s, rx2620s and a DS15 and also an SGI Tezro), LC FC cables optionally available, too; - Mellanox 40-Gbit InfiniBand PCI-E adapters (3 total), optional copper and fiber-optical cables, in various lengths, are also available; - various (e.g. HP) HBAs, notably SCSI (e.g. Ultra160 and Ultra320) and FC (e.g. 2-Gbit and 4-Gbit), for PCI/-X or PCI-E, many PCI/-X cards also compatible with IRIX and even OpenVMS, some include the HP-branded "combo" types, providing both dual-channel FC (HBA) and Ethernet (NIC); - various optical/tape drives and media (e.g. DVD-RAM, various data & cleaning tapes, of which many brand new), DDS/DAT of many types (e.g. DDS-2/DAT12, DDS-3/DAT24, DDS-4/DAT40 and DDS-5/DAT72) Ultrium (mostly LTO-1 and LTO-3), mostly of brands like HP (notably), Quantum and Sony... to summarize several: -- HP Ultrium LTO-3 SCSI half-height tape drives -- Quantum Ultrium LTO-1 SCSI full-height tape drive -- various Ultrium LTO-3, -2 and -1 cleaning and data cartridge tapes (mostly HP-branded) -- various (HP and Sony-branded) DDS-4/DAT40 tape drives, also one DDS-5/DAT72 drive, all with -- various DDS-5/DAT72, DDS-4/DAT40, DDS-3/DAT24, DDS-2/DAT12 and DDS-1/DAT8 tapes; - various DVD-RAM discs, both with and without the plastic caddies; - various HP, AXUS and Ciprico brand Ultra320 SCSI/S-ATA-bridged & 2-Gbit or 4-Gbit FC external enclosures, for HDDs (optionally including large capacity HDDs, also hardware RAID functionality depending per enclosure), 5?" devices and more (these can be tricky to ship, but not impossible), to summarize some of it: -- AXUS Demon SA-16U4P Ultra320 SCSI<=>S-ATA RAID storage enclosure, including 16 * 1-Tbyte S-ATA HDDs and spares --> advantages: relative low power consumption and triple-redundant power -- Ciprico/Huge Systems MediaVault 4-Gbit FC/FC-AL RAID disk array, including transceivers, 10 * 250-Gbyte P-ATA HDDs plus one or more spare HDDs --> advantages: low power consumption and rather silent -- HP StorageWorks M5313A FC/FC-AL 2-Gbit (JBOD) disk array, including transceivers and 14 * 146.8-Gbyte FC HDDs and one or two spare HDDs, too --> note: perhaps not useful for OpenVMS users as-is, as JBOD and FC-AL are a no-go, but it can be used in a larger SAN setup; - various types of printed documents/documentation (various manuals and reference guides, from e.g. SGI and Intel); - APC Smart-UPS 3000 XLM (heavy-duty, 3000VA capacity) UPS back-up battery aggregate power system, plus special APC RJ-45 USB cable (the whole unit is perhaps hard to ship, but not impossible I guess), this UPS can sustain e.g. several 2U and even some 4U HP Integrity servers for up to 30~40 minutes (depending on the loads, of course); - HP OpenVMS Alpha V8.4 SPL (Software Product Library) July 2010, including the original box and 'documents'; - lots of relatively recent 300-Gbyte and 146.8-Gbyte 80-pin (SCA/-2) and 68-pin 10K and some 15K RPM, hot-swap, SCSI HDDs (most are HP-branded); - older <=9-Gbyte SCSI disks, from various vendors, some with (e.g. DEC) firmware, with 50-, 68- and 80-pin (SCA/-2) connectors (many DEC and Compaq/HP-branded ones, relevant for OpenVMS and Digital/Tru64 UNIX, too); - HP StorageWorks 3U external 5?" SCSI expansion enclosure, room for 4 (68-pin) SCSI devices (including optical drives, tape drives and including full-height models); - PCMCIA and PC card items: SanDisk CompactFlash card reader, SIIG IEEE-1394a adapter, USB 2.0 adapter and an Adaptec Fast SCSI adapter plus cable; - Apple ADB and serial items: Griffin iMate adapters (2 total, 1 in original packaging) and Keyspan adapter; - Chieftec SNT-3141 S-ATA HDD backplane plus sleds and I can provide 3 * free 250-Gbyte S-ATA HDDs --> suggestion: perhaps useful for in a system like the HP zx2000 (if it fits, of course; I never tried it); - IBM System x central fan tray (P/N: 90P4618, FRU P/N: 26K4761) and also (e.g.) x346 rack rails (might fit on other devices/systems, too), SCSI HDD caddies, fans and more (ask me); - HP KVMIP console (PN 262589-821) 8-port extender hub, no power supply required for this; - Gefen 1080p HDMI scaler, professional grade (original box present), useful for some computers and monitors to correct aspect ratios; - non-computer items, or indirectly: professional SDI equipment, like JVC-branded CRT and LCD monitors, Miranda bridges (including for IEEE-1394a FireWire to SDI) and more, also many cables of various lengths available and also photo & video equipment (e.g. Nikon D70 plus Nikon Nikkor AF-S 18-70mm f/1:3.5-4.5G zoom lens, a barely used Sony HDR-FX1000/E plus accessories and various bits & parts and a Tamron TV Zoom Lens 12.5-75mm f/1.8 with C mount with constant aperture over the zoom range). All the items are located in the Netherlands. I'll provide more information and pictures on demand. As far as possible trades go. I'm mostly interested in lenses (mostly in Nikon F/G, Pentax K, Leica M, Leica M39, M42 and Sony E-Mount mounts), in particular fast longer telephoto lenses (135mm and above), also enlarger lenses. - MG

Looking for 8085a CPU

by witchy＠binarydinosaurs.co.uk

Hi folks, Still working on this STC Executel and it looks like the CPU isn't too good given how hot it gets within a minute or so. The display is the same whether there's a CPU physically present or not. I built this circuit to test it: http://saundby.com/electronics/8085/freerun.shtml Using a 4mhz crystal the address lines are all over the place - I'm using a logic analyser rather than LEDs. Has anyone got a spare they'd like to sell me? I'm struggling to think of something I've got that may have a socketed 8085... -- Adrian/Witchy Binary Dinosaurs creator/curator Www.binarydinosaurs.co.uk - the UK's biggest private home computer collection?

by jnc＠mercury.lcs.mit.edu

> It's possible that they didn't bother wiring NPG to that slot, but sent > it directly to the NPG pin on the 'UNIBUS out' connector Sho'nuff; the 11/40 prints indicate (pg. 86) that "BUS NPG" goes directly from C07P2 ("Source" - you can see the generation on print K4-5, pg. 62, lower right side), to A09U1 (NPG on the UNIBUS Out connector), do not pass through SPC slot 9, do not collect a grant. I dunno about any other oddities you're seeing, but I think this one is solved. :-) Noel

> From: Josh Dersch > There appears to be no continuity between CA1/CB1 of slot 9 and CA1/CB1 > of the SPC/MUD slots in the rest of the system. Is that the only issue? If so, that should be 'not too hard' to track down. It's possible that they didn't bother wiring NPG to that slot, but sent it directly to the NPG pin on the 'UNIBUS out' connector; when the -11/40 was done, there were no single-board DMA devices. > It's very puzzling. BTDT! :-) > I have an RK11 and an RK05 Ah, you're good then - Unix V6 will run fine with a single RK. (Ah, memories: my first experience as a sys-admin was on an 11/40 with a single RK...) The standard V6 distro include systems that will run on an RK. (The V7 distro does not, but it's possible to build RK-based systems. You'd need to bring it up on an emulator to do so.) > (with the option of a 2nd RK05 if I ever get some mounting rails for > it.) I know the RK05s are tight storage-wise. Well, you can't put all the source and documentation online with a single RK (or even two), but that shouldn't be an issue. If you were actually trying to do _real work_ on the system, a single RK might be something of a PITA. > I also have an RL02 but I need to repair an RL11 first. Put that online, and you'll have plenty of room. Also, with two controllers, you'll get higher performance (not that you care :-); you could put e.g. swapping on the RK, and most files on the RL. > I should be able to wrangle bits onto media either using what I have, > or by using stuff at the LCM, but the VTServer option sounds nice too. OK, I'll probably get back to work on it 'soon'. > The RL bootstrap and driver would be very useful to have, thanks! They're available on my "Bringing up V6 Unix on the Ersatz-11 PDP-11 Emulator" page, here: http://mercury.lcs.mit.edu/~jnc/tech/V6Unix.html#RL That page (and it's partner, "Improving V6 Unix") probably contains some other useful stuff, if you're serious about running V6. One off the top of my head: the C on the 'vanilla' V6 distro is fairly primitive. There are no longs or unsigneds, casts don't work, etc, etc. There is a later version (which I think might be the so-called 'phototypsetter C'), available from the 'Shoppa disks', you might want to get that.

So I assumed the MMU required this option > be present... Hmm, I didn't recall that; not sure I ever knew that! (Sorry!) I spent a short time looking at the KT11-D and KJ11-A prints, trying to see exactly what the KT11-D wanted, but I wasn't able (yet) to fully grok the interaction. >From the KJ11-A prints, you can probably work around not having a KJ11-A card by strapping the relevant outputs high or low (as the case might be), i.e. simulating a KJ11-A which is not reporting a problem. Like I said, V6 doesn't use the SLR for anything, so it's it's not actually working (i.e. reporting stack transgressions), no biggie. If you're determined, I did scan in a KJ11's PCB, so it would probably be possible to produce 'after-marked' ones - it's not a very complicated card. >> You will also need the KE11-E (M7238), as the Unix C compiler emits >> MUL, DIV etc, and even the bootstrap uses them.

I suppose I could run Ultrix-11 instead (I have that on my > 11/34 at the moment) as it'll run sans floating point hardware, We seem to be having a communication failure. You don't need floating point to run V6 or V7 on an 11/40. In addition, the hardware floating point hardware on the 11/40 (the FIS) is a variety that Unix doesn't support anyway (in the sense of, the C compiler doesn't generate FIS instructions). It's the Exteded Instruction Set (EIS) card (which supports MUL, DIV, ASHC, etc) which is necessary. No way UNIX (of any flavour) will run without those instuctions (and thus, that card). If you don't have an M7238, start looking.... BTW, what is your mass storage device? RL's? If so, vanilla V6 doesn't support RL's, but I do have a V6 RL driver, I can either build you a system that will run on an RL, or (if you bring up V6 under an emulator, so you can build systems, etc) provide it so you can add it. You'll also need an RL bootstrap (again, those are available, but not in vanilla V6). Also, how are you getting the bits onto the mass storage? V6 can only be 'cold installed' onto a blank machine from a TM11 or TM02 tape drive. Failing that, you have to put a V6 filesystem onto a disk on some other machine. Do you have the ability to write packs on another machine/OS, and the ability to get a Unix file system onto that system? Failing that, I'm in the process of getting VTServer working to transfer V6 over a serial line to a blank machine (my situation) - I got distracted before I got 100% finished, but I have it all scoped out, and can get it done in a couple of hours from where I am now.

You don't need the SLR to run Unix V6 (in fact, IIRC, it doesn't use it). For the clock, you don't absolutely have to have a KW11-L, you can substitute a KW11-P - but V6 _has_ to have one or the other, or it panic()'s - some things in the kernel have to have a working clock. You will also need the KE11-E (M7238), as the Unix C compiler emits MUL, DIV etc, and even the bootstrap uses them. The KE11-F (M7239) is useless; the V6 Unix C compiler doesn't generate that type of PDP-11 floating point. Noel

Slide Rails for Integrity and/or BA23

Hi I've just brought home a 42U rack and started mounting things currently in shelves and on the floor. But I'm missing some hard to get slide rails. Does anyone have a spare set of rails for an Integrity rx2620 or QBUS BA23 box for sale? The Integrity rails look like this: http://www.trademoon.com/assets/images/default/A6939AZ.JPG BA23 shelves look like this (except some missing parts): http://www.plccenter.co.uk/en-GB/Buy/DEC/702076101 Kind Regards, Pontus.

Some scrapper in NC has an old machine Labled TRIAD he is scrapping

by jnc＠mercury.lcs.mit.edu

> From: Josh Dersch > Someone should try to rescue that; they're very rare... I personally don't want to get into this (I'm already knee-deep in PDP-11 stuff), but I can help with the logistics; I'm down in SE Virginia, very close to the NC line. So if someone wants to do this, but is e.g. on the West Coast, I can wrangle getting it, and getting it shipped out. Noel

Some may recall the Nova 3 front panel discussion some months back. I bought a Nova 3 front panel just for the heck of it, and we discussed replacing lamp, and have the correct lamp info now. Nova 3 CPU, 2 16K boards, Basic I/O and Anyway the Nova 3 karma system was watching and guess what. http://jimsoldtoys.blogspot.com/2016/11/data-general-nova-3.html So now I may really be doing work on the lamps on both my system and on the spare front panel. Maybe the Star Trek gods are doing this, since we have a DG copy of Star Trek too. Getting scary. thanks Jim

Archiving Fortune 32:16 bits

by aek＠bitsavers.org

spent way too much time on this the past few days I dug up everything I had on the system, took pictures and dumped firmware and floppies Maybe someone will figure out how to remove the serialization some day bitsavers.org/pdf/fortuneSystems floppy images under bits/ I also started reverse-engineering the board, mostly to see how the mmu worked. Pretty basic, four base/bound sets made up of two 12 bit registers in three bytes the 12 bit adder is applied to A10-21 This all looked familiar, esp the bus pinouts. I think I had docs at one point for expansion board developers. Have no idea what happened to that.

Rogue: Mctesq was here

by rlloken＠telus.net

So I am 35 days from retirement and I have been cleaning up the office and my Redhat Linux workstation and in /usr/local/src I found: linuxrogue-0.3.7-roguecentral.tar So I exploded the tar ball and compiled it and it crashed so I carted it over to one of our Tru64 Unix Alpha boxes, took the 'g' off "gcc" in the makefile, used sed to change ncurses to curses where ever it could be found and compiled it. AND IT WORKS SWELL! Rogue is as addictive today as it was in 1982 on the VAX-11/780 running 4.2bsd. I think I will port it to OpenVMS and run it on my AS4100. -- Richard Loken VE6BSV, Systems Programmer - VMS : "...underneath those Athabasca University : tuques we wear, our Athabasca, Alberta Canada : heads are naked!" ** rlloken at telus.net ** : - Arthur Black

DEC bus receiver chips

by jnc＠mercury.lcs.mit.edu

So, I was glancing at pair of M784 Flip Chips, on early production, one late, and I noticed that the early one used SP380A's (marked "DEC 380A"), and the later one used DS8640's (marked "DEC 8640"), with the exact same PCB traces. So probably the latter is an alternative for the former. Noel

National Semiconductor 48-bit and 56-bit ECC polynomials

by spacewar＠gmail.com

Has anyone determined what 48-bit and 56-bit ECC polynomials are used by the National Semiconductor hard disk controllers? The DP8496/97 allows choice of hard-wired 16-bit CRC, or 32-bit, 48-bit, or 56-bit ECC. The 32-bit ECC is a common polynomial known as the Glover polynomial, and it's the same one used by WD and others. However, National was apparently extremely proud of the 48-bit and 56-bit polynomials they chose, and the data sheets say that they require a license agreement with National. The more common DP8466 supports 32-bit 48-bit, but allows the user to configure the polynomial. The data sheet states that National's 48-bit polynomial is available under license. WD wasn't as proud of their 56-bit polynomial; it's given in the WD42C22 data sheet. It doesn't seem to match National Semicondutor's 56-bit polynomial.

DNIX and ABCenix install media disk images.

by mattislind＠gmail.com

A guy in Sweden made the effort to image the install media for DNIX 5.3 and 5.12 as well as ABCenix 5.12. https://dl.dropboxusercontent.com/u/96935524/Datormusuem/dnix-imd.tar.bz2 https://dl.dropboxusercontent.com/u/96935524/Datormusuem/ABCnix.tar.bz2 These are for computers made by DIAB (later part of Bull) DS90 and Luxor ABC1600 (branded Luxor but developed by DIAB). https://en.wikipedia.org/wiki/Dataindustrier_AB https://en.wikipedia.org/wiki/ABC_1600 They all were 68k based. The early DS90 had 68010 + 68451 MMU. The ABC1600 had 68008 and some homebuilt MMU. The ABC1600 is quite a nice machine with 768x1024 b/w portrait screen that can be twisted into landscape. It has a simple windowing system. Actually half of the hardware that make up the system is the graphics board. Unfortunately the 68008 makes it quite weak. I hope that the imaged disk can end up in a safer place than my dropbox, for example Bitsavers... Thanks Jonas Malm for doing the disk images (I am just the messanger)! /Mattis

On a stock RK11-C, slots 1-8, rows C-D (the bottom two rows) are empty. In the "Double Buffer" variant, they are full of Flip Chips.

So this mystery has been solved (sort of). According to some drawings I have, there is apparently something called a "Double Buffer Disk Control" variant of the RK11-C. I looked online, but there was nothing about it there, and the RK11-C Engineering Drawings at BitSavers don't cover this variant. Does anyone out there have one of these? Noel

Today in the age of pointer-graphics, ie., using a mouse, is a very important day: Nov. 17, 1970, Doug Engelbart, of SRI, Menlo Park, CA, invented the mouse or granted a patent for "X-Yposition indictator for a grahics display." BTW he doesn't know who coined the word 'mouse'. Happy computing! Murray :)

General TC11 DECtape diagnostic/formatter questions

by derschjo＠gmail.com

Hi all -- I'm working on getting a TC11 + TU56 running at the LCM+L. We plan to use it as a tool for various archival and restoration efforts. After restoring the power supplies, I have it lashed up to a PDP-11/44 -- I know this is anachronistic, but it's been a workhorse machine with ethernet and SCSI, which makes it very flexible. So far, so good. I have RT-11 running and it can read and write tapes, although the left TU56 transport seems to be a bit marginal. I am running into a couple of issues, and I'm curious if anyone else out there has experience here and might be able to shed some light before I spend a lot of time on it: 1) In bringing the TC11 up, I've been attempting to run the TC11 diagnostics, with mixed success. ZTCB runs, but reports an error with the ENDZ status bit not being set properly. So far as I can tell, ENDZ *is* being set on normal operations, but I haven't exhaustively debugged the controller yet. The other four diagnostics (ZTCA, ZTCC, ZTCD, and ZTCE) do nothing when run -- nothing is printed and there is no response. If I run them on SIMH configured as an 11/44, I see the same behavior. If I run them on SIMH configured as an 11/20, then I get the printout described in the documentation and listings. (See bitsavers -- http://bitsavers.informatik.uni-stuttgart.de/pdf/dec/pdp11/xxdp/diag_listin…). I haven't yet dug in to see what accounts for the difference -- any ideas? 2) I'm looking for means to format DECtapes on the TC11. I have a few marginal tapes and I'd like to see if reformatting them brings them back to life. The maintenance manual only indicates "a special program supplied with the TC11 system," and I haven't managed to find it. I *have* found this: http://mirrors.pdp-11.ru/inf.informatik.uni-stuttgart.de/pdp11/dtf.mac which I've assembled and run on RT-11 and it goes through the motions of writing out the timing and mark tracks, but when it goes through the second pass to write out the block numbers it fails immediately, with either status 001207 (indicating a "Data Missed" error) or 020033 (Mark Track Error). I haven't yet hooked up a scope to see if the T&M tracks are *actually* being written, but given my experience with the diagnostics in (1) above, I'm not averse to thinking there may be more than meets the eye with this issue. So in a nutshell: Anyone used a TC11 on a later PDP-11 (like the 11/44)? Anyone have any thoughts on the diagnostics and formatter issues? Thanks as always, Josh
