Hi all, I am in the market to obtain the PDP-8/e small computer handbook in the form of a real book. There is one on ABE books available which is softcover. I always worry about a 500 page book in softcover in terms of the binding and general sturdiness. Was there a hardcover version of this book and does anyone have one for sale? Thanks Eugene W2HX

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 htis...) 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

SWTPC 6800 issues again

by vintagecomputer＠bettercomputing.net

Hey guys, You might recall a while back I was having issues where I'd have to power up/power off multiple times before I'd get the 6800 to start up correctly and give me the SWTBUG prompt. What I did was remove an overwrought modified RAM board and replaced it with a more basic 4K board set to the $A000 range. That worked great for a while, but not we're getting back to the situation where I power up many times and get either ? marks, a string of 4s, or some other random character. I have to power off and on several times before I get the $ prompt. I figured out how to run a proper RAM diagnostic and no errors came back. I wasn't sure how to properly test the $A000 board - I assumed I couldn't let the test test the address space used by the test program itself, so I set it to run from A07F to AFFF (I think I did that right, I set the MSB in A002 to A0 and LSB in A003 to 7F, and for the upper limit MSB in A004 to AF and A005 to FF). I'm wondering now if this is really a RAM problem or maybe something else. I don't think it's the serial card.. I've tried both the MP-C and MP-S and no change. I have an NOS MP-B2 motherboard here. The 'check pins' on the molex connectors for the cards haven't even been cut. I could set that up for testing although, being totally unused I'm hesitant about altering it. What do you think on that?

pdp-8e power test/lamps

by w2hx＠w2hx.com

Hi folks. As I begin getting my 8e running, after checking the PS for proper voltages and ripple I connected up the front panel. This picture is with all cards removed, just the PS and front panel. http://w2hx.com/x/VintageComp/PDP-8e/power-applied-no-cards.jpg Can anyone tell me if I have burned out bulbs (7 not illuminated in total)? Or is this inconclusive because they may be in some random state? Or, with all cards out - should I expect all lamps to illuminate? I have read all of the info/threads on bulb this great community has produced, I found a company with a stash of OL-2 which I will probably go with once I determine if I have a bulb problem or not. Thanks Eugene W2HX

Other SMS300/8X300/8X305 uses?

by seefriek＠gmail.com

I vaguely recall a T-1 network controller with a 8x300 series controller in an X.25 node about 30 years ago, but I don't have any supporting doco. I think it's pretty clear that uses other than disk controllers were very rare. KJ

VAX 4000-100 QBUS cables

by jnc＠mercury.lcs.mit.edu

> From: Pontus Pihlgren > The machine also has a qbus which is somewhat peculiar to find in a > desktop VAX. I don't know much about Vaxen, but I think the early desktop ones all had a QBUS. I'm not sure if it was ever used for memory access; I know some used it as an I/O bus (to take advantage of all the existing QBUS I/O devices), and used an 'over-the-back' cable system for the memory bus. > However, I don't have the cables necessary to attach a QBUS expansion. > Does anyone have a set? What do they even look like? They are a pair of boards connected with a pair of 50-pin cables. The boards are different on each end, because the QBUS does not have in/out connectors which separate from device slots, like the UNIBUS; it only has regular QBUS slots, and those have grant in on different pin from grant out. So on the card at the end of one backplane, the grant line is connected to the 'grant in' pin, and on the other card, to the 'grant out' pin. There are a whole bunch of different card and variants thereof for this, with and without termination resistors, etc; the M9400/M9401 pair are for Q18 (which you won't want, I'd be pretty sure), and the M9405/M9405 for Q22. One set I know of is an M9404/M9405-YB. There's a fair amount of discussion of multi-segment QBUS systems in the QBUS PDP-11 processor/etc manuals, as far as the termination, etc goes. As to finding a set, there are some available on eBait at the moment for a not wholly unreasonable amount of money. Noel

DEC M9312 Configs for a 11/40

by billdegnan＠gmail.com

Hi all...I am hoping there is someone here who has an 11/40 or 11/35 and a M9312 ROM terminator card. I'd like to know how you have yours jumpered. I took photos of the jumpers installed in my M9312: http://www.vintagecomputer.net/digital/PDP11-40/M9312/ Here is the page from the manual that describes jumpers per UNIBUS system type: http://www.vintagecomputer.net/digital/PDP11-40/M9312/M9312_Jumper-configur… 1) Yes or no - Did I correctly identify the location of W8? 2) Yes or no - Should W8 be in for am 11 40/25/10/05 or is the /40 special? Here is the issue....when I jumper W8 the CPU can do very little and I cannot activate the CONSOLE ROM. I put in posts into what I believe is W8 so I can switch back and forth without having to re-solder. With W8 out the system works better, and I can at least get to the CONSOLE prompt. Looking for opinions as to whether my card is correctly configured. I am trying to determine why I can't bootstrap and run a TU58 nor RL11, yet I can load and run BASIC just fine. I think I may have a UNIBUS problem OR a CPU card problem, but I can't load XXDP either to determine for sure. There are more problems, I can't bootstrap the RL11 nor TU58 manually either, I am working through everything CPU and UNIBUS too. Is there a complete XXDP tape that I can download from PDPGUI? I found TU58 image but I can't get the TU58em emulator to work yet. If I could just figure out why I can load BASIC and not RL02 RT11 I'd make my day. Thanks Bill

VAX 4000-100 QBUS cables

by pontus＠Update.UU.SE

Hi I brought up a VAX 4000-100 yesterday to test DSSI disks. It worked like a charm. The machine also has a qbus which is somewhat peculiar to find in a desktop VAX. However, I don't have the cables necessary to attach a QBUS expansion. Does anyone have a set? What do they even look like? Kind Regards, Pontus.

Bringing up a PDP-8e

by w2hx＠w2hx.com

Hi folks, This is my first vintage computing project. I have a PDP-8/e with the following boards in this order. FRONT PANEL M8330 KK8E CPU Timing board (system clock), replaces M833 M8300 \ KK8E CPU Major registers M8310 / KK8E CPU Major register control M837 MC8E Extended Memory and Time Share Control M849 SHIELD CORE1 \ CORE1 / CORE2 \ CORE2 / M8320 KK8E Bus loads Each core pair is 16KW. There are a bunch of other non-DEC boards (ECRM) that I have removed for the time being. You will notice that I have no serial board (yet. I have a line on one). I have cleaned up the machine, removed and clean out the foam, cleaned the card sockets and card edges, tested the power supply. I am ready for the next step. Next, I will put the boards back in and start testing. I am looking for some very simple programs that I can key in from the front panel to do some basic testing. I have found simple programs on the internet but they are all in assembler and I don't yet have the knowledge/tools to convert them to switch-enterable programs. For example, here are some good test programs but not directly enterable on the front panel (or at least I don't know how). http://dustyoldcomputers.com/pdp8/pdp8i/testprogs/index.html Can someone direct me to some simple sequence of switch settings to do some basic testing? Many thanks in advance Eugene W2HX PS. Here is more on the machine as received: http://w2hx.com/x/VintageComp/PDP-8e/ Also as you will find on the internet, the ECRM boards are from a company that produced electronic character recognition systems.

Macintosh Portable

by pye＠mactec.com.au

Does anyone know off hand what polarity that Mac Portable requires? I know that the original was 7.5V @ 1.5A, but not sure of the polarity. I did have have a PB100 power supply that I used with mine, but (unfortunately) no longer have it. Also (if it still works) what is the easiest way to image the old Conner SCSI drive? It doesn?t appear to have a standard connector. I have googled this, but didn?t come up with anything useful. Thanks, Chris...

Macintosh Portable

by spereira1952＠comcast.net

I am not certain exactly what you mean by polarity in this case, but I?m guessing that you are asking which contact is positive and which is negative. If that?s the case, the center socket is positive, and the outer jacket band is negative. I hope this helps. smp -- Stephen M.

Magnetic media FTGH!

by mouse＠Rodents-Montreal.ORG

I've just dug out and inventoried two boxes of magnetic media. A little of it is not mine; a little more is stuff I'd like copies of if I can make it happen. But most of it is just going to leave soon, one way or another. I'd rather see it go to someone who can actually use it, but it is not worth the costs of keeping it around to me. I do not currently have any system on which I can check the contents of any of these (while it's possible I might get one or more set up, I can't count on it, and it's unlikely to happen soon). So, while the labeling might be accurate, it also might not. There are a bunch of TK50s (or something similar; I know there are other, similar, tapes, some similar enough to fool a quick inspection; I didn't look in detail to be sure every one is a TK50). They have labels, some printed, some scribbled, some carefully handwritten. Here, \ indicates a line break. SW/gnu \ Nov 28/91 /usr/local \ 91/10/26 6.0 + 797493 ULTRIX V4.2 \ SUPPORTED SUBSETS \ VOL. 1 ULTRIX V4.2 \ SUPPORTED SUBSETS \ VOL. 2 Sunclock \ 91/11/21 AQ-PE1F0-01 C01 \ DEC FORT ULTRIX V3.2 BIN \ TK50 AQ-PE1F0-01 \ DEC FORT ULTRIX V3.2 BIN \ TK50 ULTRIX V4.2 \ MANDATORY UPGRADE Kermit5A \ 91/11/21 DEC FORTRAN \ V3.0 (crossed out and "obsolete" written in) K2 /usr/local \ 1991/03/14 LOTUS 1-2-3 \ 91/11/19 /usr/users \ 91/10/20 swTeX.tar.Z \ 91/11/02 ULTRIX V4.2 \ UNSUPPORTED SUBSETS There are numerous quarter-inch cartridge tapes (the DC600 formfactor; many are DC600s or DC600As, but some are other sizes/lengths/formats). Some have no label. Three of these have absolutely no label, not even a manufacturer/brand label. Nine more have a brand label but no indication of their contents. One has a printed label which has been ripped off enough that all I'm sure of is that it had the usual boilerplate text for US Government users. Two others have ripped-off labels; on one, all that remains legible is "tix" at the end of a word; the other, I can see enough of a logo to be fairly sure it was an Accelr8 label.

Wanted for RSX-11M Plus 4.6: the DECnet install tapes

by oscar.vermeulen＠hotmail.com

Hi, I am trying to do a clean install of RSX-11MP 4.6 on simh. I have found the install magtapes on Bitsavers, and they work fine. However, trying to install DECnet, I found only 1 of the 2 (or 3) install tapes. What is missing is the decnet11mp46-deckit tape. The accompanying **netkit** tape is on Bitsavers, but not the **deckit** tape. So you cannot complete the install process... Does anyone have this tape? I know there's an installed simh *disk* image, I also know you can fix the problem with it. But there is just nothing like having a full, proper install process to come up with your own setup :) And it would be nice if the last version is preserved completely. Kind regards, Oscar. For reference: A. installation magtapes for RSX-11 M PLUS 4.6: 1. http://www.mirrorservice.org/sites/www.bitsavers.org/bits/DEC/pdp11/magtape… 2. http://www.mirrorservice.org/sites/www.bitsavers.org/bits/DEC/pdp11/magtape… B. installation magtapes for the accompanying DECnet 11mp46: 1. http://www.mirrorservice.org/sites/www.bitsavers.org/bits/DEC/pdp11/magtape… 2. MISSING: the DECKIT tape.

A good shipping service for large computers?

by jnc＠mercury.lcs.mit.edu

> From: Todd Goodman > Did you have any issues with customs bringing in the racked equipment > from Toronto? No; it just sailed right through. The fact that it was Canada->US probably helped. IIRC PakMail in Toronto picked a customs broker - or maybe we were talking about doing that, and he decided we needn't bother? I forget now. > Both times the carrier knew it was unpalleted computer equipment and > did a good job using blankets and strapping them into the trucks. > ... > The other carrier did a great job .. They mostly ship antiques and > pianos and other items that can be fragile and not palleted > ... > Both were very competitively priced in my experience. Sounds like these were both so-called 'white glove' shippers, who do things like furniture, etc. Those are also an option, but in my experience, somewhat more expensive: when I was shipping a pair of -11/84's from California to Virginia, the shipping cost just about doubled when I had to switch from freight to 'white glove' for them. Hence my advice to palletize stuff, and send it freight (at least for cross-continent, where the difference really adds up). Noel

A good shipping service for large computers?

by jnc＠mercury.lcs.mit.edu

> From: Devin Davison > I am uncertain of a good service to use for the task, i need the > machines to be packaged up / put on a pallet at the pickup location I have had good luck with PakMail (http://www.pakmail.com/); I've had them ship a couple of 6' racks (one from Arizona, one from Toronto), and been very happy with the results. The shipping cost in the Arizona case may not have been the absolute lowest possible I could have secured had I been on the spot, looking around, but.. I wasn't on the spot, looking around; and it was pretty reasonable (I've shipped a number of large items from the West Coast, so I think I'm reasonably well calibrated). And they went to the person's house, picked the thing up, put it on a pallet, and shipped it. A tip for keeping costs down when shipping via freight (i.e. on a pallet, which generally is a key thing to do to keep costs down) to one's house (i.e. not a place with a loading dock): if you have a vehicle which can hold the item(s), have it/them delivered to the nearest freight terminal, not the house, and go pick it up. That way, they won't have to roll a truck with a lift-gate to your house, which is an extra cost. Every line I've ever used (SAIA, FedEx Freight, etc) were happy, when one arrives to pick it up, to dump the shipment in their yard, and let one take everthing off the pallet and load it all into your vehicle. (But check with your local terminal first, to make sure they're OK with it. And check the weather prediction to pick the day to go get it! :-) And you generally save a couple of days, too. I have discovered that a Ford Taurus wagon nicely holds an H960 6'x19" rack (I joked that the car must have been designed by someone who collects old gear :-), so I have been able to pick up a shipment consisting of _two_ H960's this way: one inside, and one on the roof rack. With only one person, one has to remove the heavy units first, and put them in the car separately, but it can be done. Noel

A good shipping service for large computers?

by lyokoboy0＠gmail.com

I have purchased 3 large SGi crimson computers and need them shipped from california to florida. I am uncertain of a good service to use for the task, i need the machines to be packaged up / put on a pallet at the pickup location, the owner is unable to do so. Usualy I would use YRC freight, however they do not offer the service to package the machines on site. Hopefully someone here can make a suggestion. Ive never dealt with shipping something this large before. I did have a Microvax 3800 shipped with YRC freight, however that was purchased through a business and was packaged before shipping. The crimsons will be a bit larger. I have the machines paid for, but figuring out the shipping has had me a bit stumped for the past few days. --Devin

Data General CS 200n (Ebay warning)

by jwsmail＠jwsss.com

This system has several tape drives, and possibly some Eclipse era processor. If someone knows what this is they may want to rescue it. There are three what appear to be 6' racks with various tape devices, and a desk high cabinet. There are two 3 or so switch front panels, one on one of the 6' racks, and one on the low boy rack, may be a simple reset run power type panel for each. Lincoln Nebraska 4822.33 bucks Data-General-Model-CS-Series-200n-Commercial-Series-Terminal-Controller-Vintage/ http://www.ebay.com/itm/282212431051 No interest, just reporting. May want to ask the vendor if there is more to this, and whether a possible system was scrapped. If so explain to them that they have scrap iron, and should have sold the system cabinets for real money. thanks Jim

Some of the first implementers of SPFs were outfits that the rest of us would call spammers. As for Micro$oft, my employer trashed our Zimbra and PMDF servers and sent us over to Office365 so now I spend my time babysitting Exchange in the cloud, writing PowerShell scripts, and waiting a Micro$oft minute for things to happen that used to be immediate. And you are right, Micro$ofts loves SPFs but they do nothing at all to expedite our mail through their servers. And in honour of Micro$oft, SPFs, and my 21st century managers, I am retiring in 29 days. -- 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

Reverse-engineering WD1000, WD1001 hard disk controllers

by spacewar＠gmail.com

I've been working a little bit off-and-on for years on reverse-engineering the WD1000 and WD1001 disk controllers (8X300/8X305-based), and their clones. I've only made any significant progress within the last few days, after hacking together my own disassesmbler which deals with the Fast I/O Select PROM. I do NOT recommend using this disassembler yet, for reasons that are explained in the README, but I've put it on github: https://github.com/brouhaha/s8x30x I've made some progress interpreting the firmware of an early WD1000, which only had 512 words of firmware, and didn't support run-time configurable sector size selection. So far I've figured out how they handle the host reading and writing the task file, dispatching the commands, and much of the sector ID search.

seems odd some list serves have this problem and some do not out there... which would suggest it may be a matter of the way the listserv is configured.

Happy turkey day to the list

by barythrin＠gmail.com

Should we do some sort of tradition of what vintage computing item we're thankful for? If ?that's too much of a repeat it could be a vintage project this year that you're thankful for. I know we're all thankful for Jay and classiccmp.org. I'm thankful for my recent successful visit to San Jose. ?I was fortunate enough to get to experience both Weird Stuff (first time) and the CHM (2nd time but previous was VCF 10). Was great to hear some other visitors at the museum bringing up memories and some chatter about teaching kids about old tech. One visitor was talking about how he had a class do a sort of human logic array so they'd hold hands if it was true or false (like the battery, thread spindle/paperclip, light bulb intro form building your own computer books). Picked up some Byte magazines from Weird Stuff as a souvenir and of course bought some shirts and a donation to support the museum. On the 8.5 hour drive back to wgere i was supposed to be I listened to some old RCR podcasts I think it was David Greelish, Bill Degnan, Earl Evans and Jason Scott) lol. Probably one of the first couple episodes. Good time and you all kept me awake on a dark Pacific Highway 1. So thankful for you all too. :-p? - John

iRMX II lives!

by aek＠bitsavers.org

Used Dave's emulator to image the hd in an Intel SYP310 and to my surprise it had an iRMX II (286) development toolchain on it. The MAME guys got it running in simulation in about 30 minutes. Anyone have any documentation or software distributions? iRMX development stuff is extremely hard to find, esp the 286 version.

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

The display is the same whether there's a CPU physically present or not.

> 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.

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

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

Hi all -- I'm finally turning my attention back to my 11/40 (which I started working on 7 years ago and never quite got around to finishing -- I've learned a lot since then and I'm hoping to be able to debug it properly now). My ultimate goal is to run V6 or V7 UNIX on it -- I have the MMU but I'm looking for an M787 (line-time clock) and M7237 (stack limit register) to complete the set. I have other DEC stuff for trade, drop me a line... Thanks! Josh

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.

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.

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

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

Google shows no trace of that email address and while not a red flag, usually something is in the search results for someone's email address. I have never seen where paying someone on ebay via paypal required them to "accept the funds". They just "get them" I thought. Crossing my fingers.... J

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

KIM-1 Debugging tool

by dkelvey＠hotmail.com

I've been making a debugging ROM board to test out the various parts of the KIM-1. It is based on taking over the KIM at reset and running test. So far I've got two test working. One is a basic, is it running test that just blinks a light on the debug board. The next is a test of the first 1K of RAM. A little tricky to do without RAM. I expect to write some more for the RRIOT ics. If anyone has interest, they can follow me on the Vintage Computer Forum or contact me here. The board has 3 ttl ICs, a 2764/27128 EPROM, a couple LEDs and a dip switch. Also a few pullup resistors and capacitors. Dwight

NCD19 / Xncd19

by seefriek＠gmail.com

From: Rico Pajarola <rp at servium.ch> > Does no one have NCDWare 3.2.1 or earlier? Nostalgia...I really liked the NCD 19 I used many moons ago. Reasonably snappy at the time, nice mono screen, quiet. Funny enough I recently resurrected an NCD Explora 701 (much later MIPS-based xterminal). It's wildly faster than the 19 (with 10/100 enet instead of just 10), but it's interesting to see how far modern X implementation has diverged from NCDs time: 8-bit pseudo-color is a showstopper for a lot of things, various desktops (Gnome, KDE, etc.) break in strange ways if they run at all, lot's of contemporary code has issues on 64-bit systems (like my old xview/olvwm code). TWM still works fine, as does the butt-ugly built in NCD Motif-ish window manager. Haven't had much time to work on it, but I'd like to get something like i3 running. I bet Mouse can add more color commentary. Reminds me...need to see if I can still get the Mouse terminal emulator to run. Probably also need to get an SCO ODT or SVR4 VM running for that old school feel. I know I've got at least one 3.x release, but not sure which one or what's in it. FWIW, I've also got some 4.x, a 5.0.x and 5.1.x; running 5.1.140 on the 700. I'm in Dublin until next week so won't be able to check until then. Ping me directly if you don't hear from me by, say, Thursday. P.S. - If anyone has an NCD 700-series or HMX (esp HMXpro24) they don't want, let me know. KJ

SPRAGUE capacitor for Tektronix 4051.

One of the DC filter capacitors has gone open circuit in my Tektronix 4051. It is a SPRAGUE 9600 uF - 30VDC with a little bit unusual foot print. It might be common for other Tek equipment. Google turned up one Ebay-hit for a completed auction but that's it. Anyone has a reliable source for this type of capacitor: http://i.imgur.com/P0Nz5KW.jpg

Old Epson printers

by ard.p850ug1＠gmail.com

Talk of the MX-80 has reminded me of a couple of more obscure models... The first is the TX80. This, I think is a little older. The mechanism is strange, it has one DC motor (and no steppers). The motor drives a dual-pitch scroll thing (sort of a coarse leadscrew) that as it turns in one direction moves the printhead left to right and then returns it more rapidly. On the return journey it (mechanically) causes a linefeed. I have never seen a complete TX80, but the mechanism turned up in an early Commodore printer (2023 or some such) and I think I have a logic board from the Epson one somewhere. The other is a bit later. The HI-80. This is a 4 (ballpoint) pen plotter. No, not the well-known Alps mechanism. This has the 4 pens on a sliding mechanism on the carriage. It is moved by running the carriage into the end stops (!). There are the obvious 2 stepper motors (one for carriage movement, one to move the paper) and a solenoid to lower the pen. The HI-80 certainly has the connector for optional interface boards. I think the TX80 does as well. Incidentally I am looking for any manuals for the HI-80. Documentation on the TX80 would be interesting too. -tony

more on lisp compilers

by rlloken＠telus.net

So last week there was some conversation about lisp compilers and an expressed interest in old VAX lisp comilers. Co-incidently, I was rooting through the morgue at work on semi legitimate business and found VAXlisp 2.2 copyright 1987. Sadly, it is on a TK50 and is the Ultrix version. Since it sparked my interest, I went through the rest of the pile but no VMS lisp compiler was unearthed. I found o-l-d VAX/VMS ADA, C, basic, pascal, fortran compilers but no lisp compilers and all on moldering TK50s lying in wait for any hapless tape drive that may accept them. Oh yes, this is all VMS 5.5-1 stuff, there seems to be an entire distro there plus a lot of layered products. These are reduntant, my employer's last VAX is now sleeping in my basement. -- 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

General TC11 DECtape diagnostic/formatter questions

> From: Christian Corti > Seems the original must have been the XXDP TC11 DECtape formatter > program by Robert J. Collins. I have no clue where I found the RT11 > version of this So that made me wonder if the V6 Unix version of tcf.s really was related to DTF.MAC. I checked out the two of them, and it seems they are likely un-related; very different structure, etc. BTW, I noticed a couple of places in DTF.MAC where error checking code was commented out, e.g.: ;EHLT4: XX ;HALT WITH BLK#IN LIGHTS, CONTINUE ; MOV #257.,R0 ;TO FIND DATA WORD POSITION ; ADD TOG1,R0 ;DETERMINE WHICH WORD IS WRONG ;EHLT5: XX ;HALT WITH #OF WORD IN LIGHTS. 0=REV.

I had a look at tcf.s, and it depends on having been loaded by the V6 disk bootstrap - it uses the console driver in the bootstrap (the bootstrap leaves a pointer to it in R5). So it might be easier to use that DTF.MAC, which seems like it's mostly the same program, and which you apparently already have working? If you'd still like to use the V6 tcf, due to the teletype driver issue, probably the easist thing is that I could make up a miniature disk image (RK05, if you have that available), with both the V6 bootstap, and tcf on it. Otherwise, I might be able to cobble something together; a hacked version of tcf including the console driver, or something like that. > Something that XXDP can load would be useful. I know nothing of almost any DEC software, alas - I'm assuming it can handle .LDA files, but I don't know which format it prefers. > From: Christian Corti > I enhanced DTF with some useful messages and error/status output.

Hi, my version of the MACRO11 cross-assembler for PDP-11 is now on https://github.com/j-hoppe/MACRO11 . Among others it fixes the "JMP Rn is illegal" error on "jmp (rx)" opcode.

The fact that the simulator produces identical results to the real hardware would argue that it's not a bug in that particular hardware. So it must be some real difference between the two. There are subtle differences between the 11/20, and other 11's - e.g. on the /20 SWAB does't clear the V bit - maybe it's one of them? It might be worth trying setting the CPU type to other values, and see if it works on any other machine type. > 2) I'm looking for means to format DECtapes on the TC11. ... The > maintenance manual only indicates "a special program supplied with the > TC11 system," and I haven't managed to find it. The UNIX V6 distro includes a standalone program, tcf.s, to format DECtapes.

Wang 2243 drive enclosure

by jason＠smbfc.net

Are there any Wang people on this list? I came across a Wang 2243, which is an enclosure w/ 3 8-inch floppy drives in it for $75 in the local surplus shop. Is there a demand for something like this whole or is the value in the drives? I've been wanting to mess around with some 8-inch drives, but it seems a crime to break this unit apart. There's also a smaller Wang enclosure with dual 5-inch floppies in it, but I wasn't able to get a model number off it. Also $75 There big to store, and cut into my retro computing budget a bit -- but I'm tempted to grab them.. Is there any potential interest here in these units before I go back for them? --Jason

PDP 11/20 sold (ebay warning)

by jwsmail＠jwsss.com

Looks like someone put in a high enough bid to hold onto the 11/20 that went today. I guessed an amount around what it went for would be what I'd pay, so don't know if I'd have gotten it or not, but didn't try since that was around the 3500 dollar level. (it sold for $2961). The fun thing is the buyer is also buying vintage clothing and the like according to Epay's useless buyer history it gives out now. There were three other bidders that doubled the price in the last 8 seconds. It was a nice machine, though the seller said it had developed a problem in the memory. thanks jim http://www.ebay.com/itm/222300550527

Page 4-39 has the logic for the front panel, and that was enough to narrow it down to one instance of STOPL in the schematics, in the middle of page H-9. E39 (an 8881 aka 7439) or E33 (a 7402). I swapped those two out, repaired the trace that I busted, and viola! HLT now works. I vaguely remember it was the 8881 at fault. BTW, I'm open to suggestions as to how to even begin debugging an HP 1000 E Series. There seems to be a case holding a power supply in the way of any access to the motherboard. The machine fails to exit the 'counting' self test right after power up. I plan on writing up a better description once it gets cold and snowy out, so don't feel bad if you don't see this plea for help. Cheers! b

It's BASIC Week again!

by fozztexx＠fozztexx.com

I do a regular contest on RetroBattlestations called BASIC Week which is a sort of tribute to the days when it was common for programs to be published in books and magazines and people would type them into their computers. One of the neat things about distributing software through type-in listings is that there?s no need for working disk drives or tape drives, or to do complicated things like get a serial connection working and find a way to transfer files. If a computer has built-in BASIC just turn it on and start typing! Past programs have displayed vector graphics, silly text screen animations, and a couple of games. This time around the program is called Winchester Drive and the concept is to explore a mansion to see what you can find. I decided this time around to try out true sprites and made a version for both the Apple II and Commodore 128. I wanted to do a Commodore 64 version but couldn't find any line drawing routines written in assembly anywhere! I thought for sure in the last 33 years some book or magazine somewhere would have written a couple of simple routines to clear the graphics screen and draw some lines that you could POKE in and then call with SYS. Oh well, I will leave the C64 version to someone else. :-) The challenge is more about honor and glory and getting an excuse to show off old computers and/or skills with porting, but I do give out vinyl decals & stickers for prizes (http://imgur.com/a/iAS5T). I know that the TI-99/4A, Atari 400/800, Coleco Adam, MSX, and maybe some others also had sprites. Sprites aren?t really needed for porting to other systems, they?re just an easy way to move the player around the screen. The program could definitely be ported to systems that use simple character graphics or even plain text screens. The complete source code has been posted to github, and you can see the full rules and check out other submissions here: https://redd.it/3ko0nd -- Follow me on twitter: @FozzTexx Check out my blog: http://insentricity.com

Mac SE NVRAM battery removal

by jules.richardson99＠gmail.com

So I'm working my way (more slowly than I probably should be) through my systems, ditching ancient on-board batteries before they leak... In the case of the Mac SE's, are there any critical settings which I should make a note of before removing the on-board battery? Should I expect any issues trying to run the machines without? (I'm not inclined to replace batteries unless I have to, just so I don't have to worry about replacement again in x years time) cheers Jules

Analogue monitor board repair

by witchy＠binarydinosaurs.co.uk

Folks, I think I know the answer to this before I even ask, and that answer will be 'got a schematic' to which the answer's 'no and I doubt one exists any more' but... My recent Executel addition has a 5" screen with associated analogue board that seems to be powered from a display chip I can't find any info on, and at least one of the adjustment potentiometers has suffered metal fatigue and broken: http://www.binarydinosaurs.co.uk/STCExecutelScreenPot.jpg http://www.binarydinosaurs.co.uk/STCExecutelAnalogueBoard.jpg http://www.binarydinosaurs.co.uk/STCExecutelDisplayChip.jpg I've replaced it with a seemingly common 10K modern part that I had in my spares box but it's unknown whether the display worked at all prior to it being put in very damp storage, also the rating of the failed pot isn't known but the capacitor next to it is 50V. I've also removed, checked and replaced out of spec capacitors, one of them was a 680nF 50V radial. I could only find a 63V PET version on cpc's website and did much reading on differing capacitor types, concluding that it SHOULD be OK. Power supply is known good because it's one of my working ones, the original is still dead. Hence the question - am I wasting my time without a schematic for this analogue board?

Newbie Question: How to Enable Local Logins on TSS/8

I have got TSS/8 running on SIMH (actually it is a ready-made image that I got for the PiDP8). I have set up SIMH to enable TTIX for a secondary line to connect another terminal, but when I try to login from another line (ie not the console) I get a message along the lines of a local login not being permitted. I have looked through the TSS/8 manuals on Manx, but I can't find anything that tells me how to enable local logins. Can anyone tell me how you do this? Thanks Rob

VAX Common Lisp

by john.h.blake＠gmail.com

I've been looking for it for a while as well, the only place I've seen that has it in any form is actually on the 11/780 running at the LCM (which you can of course access with a free account, if you just want to use VCL). I assume it must still exist elsewhere but it was removed >from the old software product libraries prior to any of the sets I've found archived anywhere, sometime around 90-91 I believe? There were several other CL and LISP implementations for VAX VMS but they've all fallen into the great memory hole as well. KCL in particular seems like it might be easier to find since it was freely available, but I've had no luck.

Unknown DEC indicator panel

by jnc＠mercury.lcs.mit.edu

> I suppose I should try and round up images of 19" x 5-1/4" PDP-10 > panels, too So there are quite a few, although I'm not sure they are exactly the same as the ones used in the PDP-11's, PDP-15's, etc. Those use a plastic bezel which is the same as the blank panels in the H960 racks, into which the inlay is set >from the front, and glued down to the lip inside the bezel. The PDP-10 ones, >from the pictures, and my vague memory, use metal bezels which cover the panels from the front, holding them on, so the shape of the inlay may be subtly different. Anyway, I found images (not great - all B+W illustrations in manuals) of the following PDP-1 panels: DF10 DA10 RC10 BA10 TD10 TM10 DS10 RM10B DC10 RP10-C MB10 MD10 I'll add them to the page at some point. If any has actual images of any of these, they'd be appreciated. (And no, none of them is the mystery panel in the RSTS manual.) Noel

Gould 32/77 (was: NWA auctions)

by rickb＠bensene.com

> I'm curious what the Systems 32/77 is.. >Wasn't Gould SEL? maybe an SEL system? The 32/77-series was a 32-bit machine implemented in ECL, based on earlier SEL designs, but is definitely Gould in design/manufacture. Some of the machines in the series had a very powerful (for the time) floating point unit (known as the IPU) that operated in tandem with the main CPU that vastly increased the number-crunching power available The machines were mainly intended for real-time control applications (as used in the flight sim applications in the auction) The machine ran a real-time executive called MPX-32. More information: http://www.encore-support.com/htmls/32_77.htm Years ago, I had some experience with these machines. They were quite powerful for their time, and were also workhorses that just ran and ran. Very robust design. These are neat machines, and I hope that they end up in the hands of someone that can care for them rather than ending up scrap. -- Rick Bensene The Old Calculator Museum http://oldcalculatormuseum.com

VAX/VMS Pascal, Modula-3, Oberon, what could have been....

by seefriek＠gmail.com

I've heard Modula-3 (from DEC SRC and Olivetti Research Center) called "the Ada regular programmers would adopt". They never did, of course, because Olivetti decided research wasn't that important and DEC got bought and a lot of other reasons that are documented elsewhere. Not to get into a language pissing contest, but IMO it's an awfully nice way to program, with threading built in, type safety, generics, a reasonable GC, exceptions, etc. I really enjoyed it, but then I think Ada brings a lot to the table. What might have been, indeed.

Looking for info on a CAMAC module - Kinetic 3912 Unibus Crate Controller

by pete＠petelancashire.com

Over the years I've played around with a few old CAMAC (*) modules, by today's standard they pretty much have zero value, anyway that's another story. Recently I've been offered a CAMAC to Unibus board. A Kinetic 3912 Unibus Crate Controller . A Crate in CAMAC speak is just a chassis with a backplane. The problem with CAMAC is there is almost no information out there, Since I don't YET have a Unibus system, it more of a curiosity then anything. So .. anyone have the manual ?

by rickb＠bensene.com

Hello, all, Question of the day: Will an Emulex MT-02 SCSI->QIC tape controller work with a Wangtek 5150EQ (QIC-150) Tape Drive? I am trying to resurrect an old Tektronix 4132 Unix workstation. The 1/4" Wangtek 5099EQ drive that was in the machine was toast, something on the drive's electronics went POP when it powered on the first time, and it is no longer being recognized by the MT-02 controller. I have documentation on the drive, and will probably look into seeing if I can fix whatever fried, but in the short-term, I have a Wangtek 5150EQ with a good drive wheel, and was wondering if this drive would function with the MT-02 and be useful on the machine. I have a bunch of old (1980's) QIC-24 tapes written with the old 5099EQ drive that I want to look through and archive in a different form. And yes...I know about the tension band issues with old 1/4" QIC media...I've got a bunch of new tension bands and have become quite adept at replacing them and assuring the proper tension on the tape. Wishing all a peaceful day, -Rick -- Rick Bensene The Old Calculator Museum http://oldcalculatormuseum.com

VAX/VMS Pascal, Modula-3, Oberon, what could have been....

by mark＠wickensonline.co.uk

I recently discovered the very excellent website http://pascal.hansotten.com devoted to all things Wirth. I sent a message to the author, as detailed below, but I would encourage anyone to visit the website - you will surely learn something? Greetings from Windermere in the Lake District, England! I read with interest your interview with John Reagan. His efforts on the VAX Pascal Compiler, and more recently (well, in the last few years or so) my discovery of the very excellent Theo De Klerk book on VAX Pascal and it's excellent integration with the VMS operating system have rekindled my love of this excellent implementation of Pascal. I am the organiser of declegacy.org.uk - a 'mostly' annual event here in Windermere where collectors of DEC equipment and ex-employees gather to immerse themselves once again in the excellence of product that was the result of DEC Engineering. I have tried a couple of times to 'entice' John to provide a video narrative of his time at DEC - but, thankfully, he is still a very busy man. At DEC Legacy this time around for example I was very fortunate to find myself in the 'programming zone' for a couple of hours - sat at a VT terminal, trying to determine why my VAX Macro-32 fractal generation programme would not run successfully on a DEC Alpha via the VAX Macro Compiler. For those precious moments I could have been sat at a piece of DEC equipment anywhere in the world. For a programmer this is just intoxicating and all too rare these days. I have a long standing interest in the legacy of Wirth - and indeed DEC, as could be expected. When I was considering a programming language for my PhD efforts on a DEC 3000/600 AXP running Digital Unix 3.2C in 1994 I would have been better using Modula-3 and ignoring the C-based Khoros framework which was the path I eventual took (C was a 'better the devil you know' option at that point).

Unknown DEC indicator panel

Along the same lines, the picture in the original PDP-8 manual was of a machine that had a front panel that looked more like the PDP-5 panel than the one shipped on the 8s. Given how close the machines were in architecture, it wouldn't be surprising for a prototype. As it turns out, I saw the picture in the manual a few years before I ever saw a real straight-8. To this day, the real straight-8s look a little "wrong" to me. BLS

[TUHS] Booting PDP-11's from RX02's

by jnc＠mercury.lcs.mit.edu

> From: Don North > Track 0 is not used by standard DEC software I wonder why DEC did't use track 0. The thing is small enough (256KB in the original single-density) that even 1% is a good chunk to throw away. Does anyone know? (I had a look online, but couldn't turn anything up.) If I had to _guess_, one possibility would be that track 0 is the innermost track, where the media is moving the slowest, and as a result it's more error-prone. Another is that IBM used track 0 for something special, and DEC tried to conform with that. But those are pure guesses, I would love to know for sure. Noel

Unknown DEC indicator panel

by jnc＠mercury.lcs.mit.edu

So, the CHM has an RSTS-11 brochure: http://archive.computerhistory.org/resources/text/DEC/pdp-11/Digital.PDP-11… which shows in a couple of places (front cover, page 6, 7, 10, 11) an indicator panel which I haven't been able to identify: it's the one where there are four full-length light rows on the left, and the lower right row of lights is broken up in the three groups - small, large, small. (The other indicator panel is known, it's an an RF11). I have been searching for these panels for quite a while now, and have a page for them: http://ana-3.lcs.mit.edu/~jnc/tech/DECIndicatorPanels.html _but_ ... I have never seen that panel. I am quite sure that it is _NOT_ an RK11-C panel; although no image of such has ever been found (I think because it was never produced - no DEC manual or print set refers to it), the RK11-C prints show the wiring for the connector to the indicator panel (which would presumably have been a standard DEC 19" x 5-1/4" panel of the kind documented on the page above), and from that it's possible to predict what it would look like, as shown here: http://ana-3.lcs.mit.edu/~jnc/tech/pdp11/RK11-C_inlay.txt http://ana-3.lcs.mit.edu/~jnc/tech/pdp11/RK11-C_inlay.pdf Can anyone shed any light (no pun intended :-) on what this is? The RF11 engineering drawings list (on page 187/188) all the inserts available (as of that date) for the standard 19" x 5-1/4" indicator panel, and I don't have pictures of all of them, so it's possible this is one of them. (It's clear from the brochure that this wasn't necessarily a working system, since it appears in a number of different configurations. So maybe they just grabbed up a random indicator panel and plugged it in to make the system look cool.) One possibility is that it's a prototype that was never produced - or perhaps it was the indicator panel for an earlier RK11 controller (although I can't find any mention of an RK11-B or RK11-A, and the list above doesn't contain an RK11 entry). Anyone have any ideas? Noel

If anyone could point me to a photo of the RC11/RS64 DECdisk panel > to be honest I don't know if it even had one? I'm not sure it did. The list of available inserts (in the Indicator Panel Assembly drawings, available in the RF11 prints, pp. 186-190) doesn't list an RC11 insert, and that list does include the RF11, which is a later controller than the RC11. I tried looking online for RC11 engineering drawings, to see if it included an indicator panel connector (the way the RK11-C does), but I could not find _anything_ substantial about the RC11 online. > From: Jon Elson > These look VERY posed, so don't be sure ANYTHING in the picture was a > fully working system. Yeah, I'd come to that conclusion... > If those panels look like something off a KA10 controller Well, I'm not sure. Most PDP-10 gear had rows of 36 lights, which is the full width of these 19" indicator panels (i.e. every light in a row - like the top row of the RP11 panel, see the page for an image), and I don't see that in this one. But I suppose I should try and round up images of 19" x 5-1/4" PDP-10 panels, too (ISTR that there are a few). Noel

What the heck is the deal with this eBay item

by vintagecomputer＠bettercomputing.net

I've been wondering about that one myself. ?Very odd. ?That's not the first time I've seen that either. Along with stuff that 'sells' for absurd amounts of money. At first I though the absurd sales were attempts to manipulate the market.. but it doesn't seem worth the effort or ebay fees. ?I almost kind of wonder with some of them if something more sinister is going on.. like money laundering. ?That'd be a fairly obscure way to do it..

Few do. Perhaps some flavors of RSX, I don't know. RSTS V4A, when built with the power fail handling option, could do so. Later versions do not; they unconditionally reboot (from disk) at powerup. > > paul RSX-11M and M+ did resume from power failures very robustly. I had a PDP-11/44 with batteries for the MOS RAM (and fans to cool it) with RK07 drives. I can remember testing it by pulling the power with a number of applications runnings including editors etc. The disks would yank the heads back and spin down, then when the power was restored and the drives spun up, it was like it never happened. I might see an entry or two in the error log file about a disk retry, and a user might loose a keystroke on the file they were editing but it absolutely was solid. I don't know of a single modern operating system that can do that today. RSX-11M+ can run TCP/IP today with Johnny Billquist's BQTCP package but it dies require I/D space processors. M+ itself can run on a 11/23+ or 11/24 but it really needs more than 128KW and the lack of I/D space really limits its capabilities. Mark

Has anyone here seen a 8H070 external floppy?

by isking＠uw.edu

I bought one of these on eBay thinking it was the standard 37-pin D-connector that connects to an ISA floppy controller. No, it's a 25-pin D-connector. I can't find any references in Google aside from people selling them. I'm wondering if it might be something like a printer-port-connected device, in which case I'm probably out of luck trying to find its driver.... -- Ian -- Ian S.

Imaging Old Disks Advice Needed

Is there a good tool to merge tracks from multiple disks if I find another > copy of the software that has the missing tracks? Pete: I've had pretty good luck during a data restoration project by ensuring the drive heads are clean and then also cleaning the cookie VERY GENTLY with good quality rubbing alcohol (I'm using 91%, some say you should use better stuff) on a cotton ball. My method has been to put the cookie on a clean, dry, soft surface. The disks I'm working on are Apple ][, so flippy (if the jacket is punched), otherwise I only need to concentrate on the "bottom" side of the cookie. Essentially, the side without the hub ring. I use a very fine-tipped needle top bottle (found it in the baking section of a local big-name craft store) and apply a reasonable amount of rubbing alcohol then use a fresh cotton swab and gently clean the surface. Depending on how it goes, I'll clean it a second time. Note, some of the disks look just fine, but still have some issue reading. This cleaning process has been highly successful (maybe 85%?) for me even with disks that looked clean. Also, on a few prior attempts I've had inexplicable results in trying different drives. I don't know if alignments, speeds, magnetic sensitivity or other factors were at play but it's worth trying as another trick to have in the collection. Sometimes it worked better, sometimes it was worse. I am not 100% sure, but I thought the "baking" was for media that was shedding or at some risk of having a physical issue with delamination, etc. Also, I can't really help on the merging question. I'd think you could just cut the resulting images together using a hex editor or similar. Naturally, you'd have to know where the bad parts were in the file. Maybe you could start with a 'fc /b filename.bin filename.bin' at a Windows command prompt, note the offsets of differences between multiple reads and visually compare those sections in a hex editor? Good luck with the data restoration! See ya. -Todd

I checked about a week ago, and it was down to ~26K (IIRC). Although, like I said, I doubt they have all 26K in stock themselves; based on comments they made when we bought a large group, I think that's the total number available to them across a number of suppliers, in a network which shares inventory information.

Unix Version 1 was written in PDP-11 assembler, for the -11/20; although that was a re-write of an earlier version written in PDP-7 assembler.

At that time PDP-11 was a general architecture name and 11/mumble was a specific system. Keep in mind that new versions of the -11 would evolve soon after introduction and continue over time for decades.

V7 is only distributed with pre-built loads for split I+D machines (so you can't boot a V7 distribution tape on a non-split machine), but it includes machine-language OS support files for non-split machines. (It's similar enough to V6 that it makes sense that it runs on non-split machines.) > From: William Degnan > Given 128K core, wouldn't one be able to save the OS in core, no need > to load what would need to "get started" from a diskpak? To fork a process, Unix swaps the forking process out, and then fiddles system tables so that one of the two copies (I forget which, without looking at the code) becomes the child. This includes at startup, when the 'swapping' process (0) splits and the child (1) is set up to run /etc/init. (I found this out the hard way, when bringing up V6 under Ersatz-11. :-) So Unix won't run without a swapping device. Noel

PDP11GUI 1.48.5

by j_hoppe＠t-online.de

Guys, there's a new release PDP11GUI 1.48.5 Some enhancements: 1. "Disk Image Read/Write": - Now compression of 2word patterns (32 bit patterns), did reduce download of a RSX-11 system disk from 40h to 6h. - Fix for PDP-11/44 console firmware v 3.40: ignore "(Program)" output after driver start. 2. Terminal windows now beeps on char, necessary for some endless XXDP diags. Download from https://github.com/j-hoppe/PDP11GUI/releases/tag/1.48.5 Web: http://retrocmp.com/tools/pdp11gui Enjoy, Joerg

For sale 128K Core RAM Industrial PDP 11/40 Massbus System

by jnc＠mercury.lcs.mit.edu

> From: Ed Sharpe > was Unix or C the one developed on the 11/20? Both. Unix Version 1 was written in PDP-11 assembler, for the -11/20; although that was a re-write of an earlier version written in PDP-7 assembler. C was developed from B in good part because the word address model of B (inherited from its ancestor BCPL) wasn't a good match for the PDP-11's byte addressing model. More here: https://www.bell-labs.com/usr/dmr/www/hist.html https://www.bell-labs.com/usr/dmr/www/chist.html > From: Christian Corti > I think the IP stack needs separate I/D and more memory I read that the networking code in 2.x uses Supervisor mode (apparently it needed more address space than was available with only kernel, even with split I/D).

Some pages from the 360-40 Development Manual, Hursley

by steven＠malikoff.com

I've pdf'd half a dozen pages of the 360/40 development manual from IBM British Labs at Hursley UK, early/mid 60s. I wish I had more but these only survived because dad used to bring home binders with these single-sided pages for us kids to draw on, and my parents kept them. They may not even be from the same document, but it's just for interest's sake. http://web.aanet.com.au/~malikoff/misc/IBM_360-40_Development_Manual_fragme…

DEC DS10L Fix CPUFan!

You never know until you try. Anyway, the Alphaserver 4100 has four midsize muffin fans and I found them trivial to take apart and trivial to replace the bearings which were a standard off the shelf part. It was easier to fix the fan than it was to replace them since DEC had a custom fan with a speed sensor built in that proved impossible for me to find. It changes from model to model and generation to generation. -- 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

raytheon 706 computer users manual at SMECC

by COURYHOUSE＠aol.com

Don't be nasty Al! I was willing to scan the addendum and covers if needed. I also did not know if others with interest needed...I am glad the book is scanned already as I do not care to blow mine apart... glue backing gets pretty brittle on these things. The addendum is a loose pamphlet that was just with the manual In a message dated 10/30/2016 11:20:03 A.M.

raytheon 706 computer users manual at SMECC

by COURYHOUSE＠aol.com

We have in the library: "raytheon 706 computer users manual" at SMECC. Wanted to see if it was online somewhere. Nice shape tight binding with an additional errata and addendum pamphlet accompanying it. I see bitsavers has manual but not pmphlet.Also there is no color front and back cover, which if you have the computer is cool artwork for a display. - Anyone with a 706 out there?
