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?

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

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

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

by jnc＠mercury.lcs.mit.edu

> 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.

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.
