So, what's the best short name for the pair of machines, the PDP-11/05 and PDP-11/10 (which differ only in the nameplate)? I have generally been calling them the '11/05's, since that's what's on many of the extant drawings, manuals, etc - and DEC seems to prefer the '05' in manual ID's, even when the title references both - e.g. DEC-11-H05SS-B-D is the "PDP-11/05-S, PDP-11/10-S system manual", with the /05 mentioned first. However, for the 11/35 and 11/40, which we seem to normally call the 11/40 (again, following DEC's lead - EK-11040-TM-002 is the "PDP-11/40, -11/35 system manual", with the /40 mentioned first), the /40 is the end user machine. With the /05 being the OEM machine, and the /10 end user one, we (and DEC) seem to have picked the OEM variant in one as the 'canonical' model, and in the other, the end-user variant. Maybe this isn't an issue/problem, but I noticed it, and thought I'd see what (if anything :-) others thought. Noel

VAX 11/730 quickie

by tmfdmike＠gmail.com

Just started working on mine - been a back-burnered project for a long time. Unfortunately all the cables were cut when it was dismantled; I was lucky to grab just the CPU. Got it powered up ok - no drama there. I faked cables to the port on the WCS which drives the console and hooked up my trust VT220 at 2400 baud. Nada. No self-test prompt; no ROM> prompt. Maybe I've messed up the faked console cable; I'll check - already tried obvious things like making sure Rx & Tx were crossed (it's a three wire cable according to the schematics - Rx Tx Gnd; no flow control). But I'd like to know more about the assorted LEDs on the CPU boards; maybe there's a clue there if it's not getting far enough into the self-test to display console output. There's a fair few LEDs on the M8391. But the doc I've looked through on Bitsavers doesn't seem to document their meanings and interpretations. Can anyone help on that point? Hopefully this link works: https://www.facebook.com/photo.php?fbid=10208521465663997&l=867897c786 Thanks Mike http://www.corestore.org 'No greater love hath a man than he lay down his life for his brother.

Offer: HP 1611A logic state analyser with option A80 for 8080 microprocessors

by p.gebhardt＠ymail.com

Hello list, I've had this HP logic state analyzer for many years now, but never found actual use for it and thus never used it. So I decided that a new home would be more suitable for it. The analyzer comes with the option to debug and analyze 8080 microporcessors. Probes are provided, but no manual. However, there is a small command overview on the front of the keyboard. The system completes the selftest and I did let it run for two hours yesterday. No more tests done, but if anybody wants me to do a specific test, then I can do it, provided you explain to me what to do. Pictures are under http://www.digitalheritage.de/other/hp_1611a/ Make me an offer via private reply. Pick-up in Bonn (Germany) or international shipping possible. However, keep in mind that the system weights 13kg (29 lbs), so shipping is not going to be cheap. Cheers, Pierre ------------------------------------------------------------------------------- Pierre's collection of classic computers moved to: http://www.digitalheritage.de

The AT&T 3B2 is still proprietary

by lists＠loomcom.com

Here's an interesting tid-bit. I just got off the phone with the AT&T corporate archives, where I had hoped to find schematics and internals documentation for the AT&T 3B2. They do have it, but unfortunately they will not give access to any of it because they still consider the 3B2 to be proprietary information. I'm disappointed, obviously, but not all that surprised. 25 years is not a long time for a company like AT&T, and I understand the 5ESS system still runs a 3B20 emualtor. They may even still have support contracts for 3B2 installations, I'm not sure. Anyway, all that aside, will soon have access to a couple of 3B2/310s, so I hope to continue reverse engineering the hardware directly. -Seth -- Seth Morabito web at loomcom.com

VMS 5.5 and multinet 4.1 SMTP Question

by billdegnan＠gmail.com

I have been working to get my MicroVAX 3100 communicating with TCPIP, and I got pretty far but I ran into a little snag. I don't have it on right now, but anyone wanted to connect for fun it's available from microvax3100.vintagecomputer.net, just give me a few minutes to fire it up. I can telnet in/out and I can send SMTP messages, but I cannot yet receive them (reply to). The issue is with the format of the email address. I was wondering if I must send emails from my VMS 5.5 and multinet 4.1 as such: MAIL> MAIL To: SMTP%"bill at myemail.com" etc.. Is there a way instead to send like this: MAIL> MAIL To: bill at myemail.com" Question #2 I'd like to be able to send messages to my MicroVAX (reply to messages). At present if I try to send a message to SYSTEM at microvax3100@ vintagecomputer.net I get a rejection from the POSTMASTER like this: Bad address -- <SYSTEM> Error -- %MAIL-E-USERSPEC, invalid user specification ':' ------------- I have been reading up and I have narrowed the issue down to the differences between DEC mail format and "modern UNIX". I don't believe anything is being blocked. I am sure if I sent an email from a VAX to my VAX it would work just fine. I am also guessing there is a translation gateway that I need to set as part of the boot up process, and that this is a DECnet issue, not a Multinet issue. I was playing around with *@MULTINET:MR_CONFIGURE *but I am unsure if that's the correct process, or how to store this so it's permanently set. http://crpppc19.epfl.ch/vms/multinet/html/admin_guide/Ch08.htm#E15E104 Anyone have any tips? I don't want to upgrade the system unless I have to.

How to use both a VT-52 and an ASR-33 on a PDP-8A

by cramcram＠gmail.com

Hi, Just looking for suggestions on how best to setup my PDP-8A so that it can use either a VT-52 (current loop version) or an ASR-33. One idea I have is a multi-pole switch to change the baud rate from 110 to 9600 and to also switch the xmit and rcv current loops. Does anyone out there have any other suggestions? Thanks, Marc

As gunkies came up a few times during this thread, please beware that those of us who update gunkies in some cases simply try to collect information that's floating around so that it doesn't disappear - gunkies is different from Wikipedia, and is meant to be. Please read http://gunkies.org/wiki/Main_Page, particularly 'Sentences starting with "I seem to recall" are perfectly welcome here' That doesn't mean that there's no trustworthy information there, but there'll be an element of "research", and sometimes hearsay, which Wikipedia doesn't allow. In other words, the output from discussions on this list will sometimes be input for gunkies, in that case it shouldn't be used the other way around.. except for defacto factual stuff like images and linked documents. (In other news, gunkies was recently moved to a "less glacial server", as the admin phrased it.. well, that's the understatement of the century, it's now easy and quick to edit. I mention this because now and then people on cctalk have asked for a place to collect lists of technical information of various types, which are not welcome on Wikipedia. This type of info *is* welcome on gunkies, and now that it's snappy to use it is a real alternative. Feel free, folks.. the only issue is that due to past spam problems it's necessary to email the admin to get an account and write access.)

dec mid-sized cabinet (TU10/TM11)

by jwest＠classiccmp.org

I had cause over the weekend to take apart my 8E dual-bay system (the TU10/TM11 is being traded off). I remembered there was some discussion a few weeks ago about the mid-sized dec cabinets with the sloped top front, so figured I'd post a pic. Mine may be somewhat unusual in that the operator controls for the TU10 are on this sloped front at the top rather than the bottom left quadrant of the drive. The rack next to it with the 8E and TU56 has just a blank sloped front in that "PDP 8E Yellow". Picture at : https://www.flickr.com/photos/131070638 at N02/24884152340/in/dateposted/ J

DEC and DG equipment for sale/trade/whatever in Houston TX

by nospam212-cctalk＠yahoo.com

Hi all, Really hate to do this but been out of work for a while and need to clear out a storage space to save some money. And I figure as much as I'd like these machine working to play with, I'll never actually get to work with them so offering them up for sale, trade for smaller more in line with my other systems items, or if it gets down to it, just get it to a good home though would be nice to get a little something out of it. Have a PDP-11/34 in a rack with an RK05J drive though I suspect the drive isn't any good now. The top of the drive is gone as I rescued this from a scrapper who had started on the drive first. Several disk packs are included but no idea what is on the disks as I didn't get to any point with it where I could tell. I did test out the power supply and then bring up the system itself and seem to run fine. The boards inside from what I recall are RK05 controller (M7254, M7255, M7256, M7257), memory (H-228B, H-222A (x2)), memory parity (M7850), SLU & Realtime clock (M7856 (x2)), an M7814, console interface (M7859), boot roms (M9301YF), and cpu (M8265, M8266). Also have a DG Nova-3 but it is basic case without any boards inside at all. Hope someone is interested and can pick them up as my only other option will be to send it all back to the scrapper. Let me know if you need any more info and I'll do what I can to get it. Not an expert on either system and they are in the back of the storage space so it could take me some time to pull them out to get any info off them. Will have some other stuff to offer up as well as I clear out the space. Best, David Williams www.trailingedge.com

seeking Briel micro-altair logo

by dave＠661.org

Does anyone here have the vector artwork for the Briel Micro-Altair? As shipped, these computers have a sticker on the front for the logo. I recently discovered that the local hackerspace has a laser cutter that can also blacken[1] metal plate. I would like to apply a better-looking logo that way. [1] The process, I gather, appears to involve applying a sheet containing resin or something akin to powder coat which is then melted by the laser and sticks to the metal substrate. -- David Griffith dave at 661.org A: Because it fouls the order in which people normally read text.

PDP-11/20 vd one that just says pdp 11 what are the date differences?? OEM?

> From: Bill Degnan >> Yes, detailed histories might (and many do) indicate that the name >> "PDP-11/10" was originally allocated to what later became the 11/15 > what detailed histories are these that you refer to that say there was > never a single KA11 11/10 sold, not one installed? I didn't say that they said "there was never a single KA11 11/10 sold, not one installed". So I just spent an hour looking through all the standard DEC histories (e.g. Bell, Mudge, McNamara, "Computer Engineering: A DEC View of Hardware Systems Design", etc, etc, etc, etc, etc) and I was unable to find _anything_ about either the 'first' -11/10; or even the -11/15, for that matter! So I don't know where I saw the mention of the 'first' -11/10 being what later became the 11/15. I _did_ find a mention of the 'first' -11/10 in the 1970 "PDP-11 Handbook" (pg. 1), with the specs as in the 1969 price list. Unlike the -11/15, which did have differences in the CPU itself, it seems that the 'first' -11/10 differed from the -11/20 only in the memory that came with it - i.e. the CPU was the identical KA11 as in the -11/20. So, do you know of any engineering document or photograph of one of those 'first' -11/10's? My bet is that there probably are none - because the machine likely never existed. (Although DEC may have sold a few, what was shipped was probably an -11/20 - with a front panel reading 'PDP-11', which may be why the earliest -11/20's said that - with the configuration listed for the 'first' -11/10.) To repeat: To the extent that one allocates the name "-11/10" to anything, it should, by virtue of the existence of _many actual physical instances_, _marked as such_, be to the KD11-B machine. Noel PS: Amusing factoid: I have a PDP-11/20 price list from April 1, 1972 which lists a "PDP-11/21"! (Versions are -CA, -CB, -CE, -CF.) It's repeated multiple places throughout the list, which leads me to believe it's not a typo.) No idea what that was all about.

There may have been some holdouts in some departments, such as silk-screening the panels. By analogy, the phrase "single density" didn't originally exist. After "DOUBLE-density" was developed, THEN "single density" needed a name. Although just sticking with "FM" and "MFM" would have been a lot better! (Although I guess that it was inevitable that marketing would invent "HD", instead of "double data transfer rate MFM".) There were even a few companies that freely intermingled HEADS V density! Intertec/Superbrain decided to call their 5.25" 40 track DSDD, "QUAD density", because it was twice the capacity of the 40 track SSDD! Then, when they added an 80 track DSDD, they caalled that "SUPER density", abbreviated "SD"! So, if you encounter an alien disk labelled "SD", it might be 720K/800K, not 100K. Similarly, if you were to search ancient archives, the phrase "World War TWO" was first used BEFORE there was any mention of "World War ONE". It wan't until a second happened, or was expected, before anybody had any reason to declare the "Great war"/"World War" to be "nuber ONE". So, the use of any sort of "first" name doesn't occur until "second" is expected. Or WW1 was also referred to as the "war to end all wars" some good name sequence comparisons here Ed#

The thing is that there never was a physical PDP-11/10 of the first type, it was just marketing plans; whereas there were/are still many physical -11/10's of the second type. Yes, detailed histories might (and many do) indicate that the name "PDP-11/10" was originally allocated to what later became the 11/15, but to the extent that one allocates the name "-11/10" to anything, it should, by virtue of the point above, be to the KD11-B machine.

The PDP-11/05 CPU was identical to the PDP-11/10 (KA11-B). The only difference between the PDP-11/05 and the PDP-11/10 was that the PDP-11/05 was made for OEM, while the PDP-11/10 was for end-users. sort of like the 8 m and 8 f were same but one oem one end user Ed# at _www.smecc.org_ (http://www.smecc.org)

PCS Cadmus/QU68000 systems

by ramdyne＠gmx.net

Hi, Is anyone interested in PCS Cadmus/QU68000 systems? We at Hack42 have no idea what to do with them. We need to downsize and these take up a significant amount of our space. See http://dev.ramdyne.nl/IMG_2750.JPG for photograph of the stack. If you know other people who are interested in beasts like these, please pass this information on. -- Andreas

PDP-11/20 vd one that just says pdp 11 what are the date differences?? OEM?

For me at least > this throws into question the whole "... the 10 first came out with the > 5 in 1972..." story everyone repeats over and over This is a known 'artifact' in PDP-11 history. DEC originally used the /10 designation for a cost-reduced 11/20. They never produced any, AFAIK - I'm pretty sure (without checking) that machine was re-labelled the /15, and those _do_ exist (I used one BITD). According to DEC documentation, the /15 has a KC11 processor, not the KA11 of the /20 (although I've never been able to find out much about the KC11 - I suspect it was a slightly modified KA11); the main functional difference listed is that it only supports one level of interrupt, not four; power-fail re-start is also optional, not standard. I have this bit set that both the /15 and /20 could be had with the 'simple' front console, that that wasn't the differentiator between them. The later /5-/10 pairing does indeed exist - I have one of each. They are absolutely identical except for the printing on the faceplate. Noel

Vaxstation 3100 - I have console access

Hi everyone. I'm hoping that one of the VAX experts out there can help me figure out how to get my 3100 booting.

Any PDP-7 Expertise?

by wkt＠tuhs.org

Hi all. Some of you may know me as the guy who set up the Unix Heritage Society at www.tuhs.org. We've been able to restore some of the old Unix systems to working order, including a PDP-11/20 version from 1972. I've just been given a scan of the assembly listing for PDP-7 Unix which includes the kernel and some user-mode programs. The scans are at http://www.tuhs.org/Archive/PDP-11/Distributions/research/McIlroy_v0/ as the files 0*.pdf. I have this crazy idea that this system could be resurrected to working order on SimH and/or on a real PDP-7. But I'd a) need to learn the PDP-7 architecture, b) write an assembler, c) OCR the scan (manually) and d) spend a lot of time debugging something that has no user manual and may not even work! I thought I'd ask here if there is any PDP-7 expertise that I could lean on if I decided to actually proceed. Many thanks in advance for pointers, suggestions, help. Warren P.S I've already found http://www.soemtron.org/pdp7.html the PDP-7 Reference Manual f75ppdp7prelimumdec64.pdf and http://bitsavers.trailing-edge.com/pdf/dec/pdp7/`

H11 Success with XXDP

by rich.cini＠verizon.net

All ? I had some time today to work on the second serial port for the H11 I received two weeks ago. I built the second cable for use with the TU58 emulator so I could load tapes into the machine. I loaded up the bootstrap using PDP11GUI, mounted the XXDPD2D tape and hit ?001000G? and it worked! Yea! Next up, locating other bootable TU58 tapes and seeing if those work.

Internal HP docs on 9845 sys?

by fulivi＠tiscali.it

Hi everyone, I've been working for the last few months on implementing the MAME emulator of HP 9845B system. In case you're interested, have a look at MAME development page at https://github.com/mamedev/mame. My emulator mostly works, the main missing thing now is the graphic mode and the ability to load optional ROMs. Anyway, I'm posting here because I'd like to ask you a few questions on HP docs. The last thing I worked on for this emulator is the "TACO" tape driver. I reverse engineered it entirely from sw & the (scarce) docs available enough that it works. So here a few questions for you: * Back in the days, what was the HP approach to document internally-developped chips for its own sw developers? I mean, was there a kind of programmers' guide for TACO chip? Is there any hope someone scanned it and made it available somewhere? I know that for hybrid processors HP made an internal manual titled something like "how they do dat" manual... * Just out of curiosity, what a big company like HP does with its "historical" documents? Do they have an archive where they keep documents & sw from, say, the 70s? Or do they throw everything away when there is some kind of company "shake-up" such as big layoff phases, closing of a site, merging and splitting of divisions? Thank you. -- F.Ulivi

Another MEM11 update

by ggs＠shiresoft.com

Just to let everyone know, I'm making pretty good progress. I just hit "code complete" on the FPGA. That means I've written all of the Verilog code for the FPGA that is the heart of the MEM11. This includes *all* of the Unibus functionality. It all synthesizes for the FPGA and the remaining warnings are all "understood" and best of all it *fits* in my chosen FPGA. Interrupts were fun because I had to figure out how to propagate the bus grants from one (internal) device to the next since their ordering isn't fixed (you can re-arrange the order of the interrupting devices...ie change their slot order). In addition, the interrupting devices aren't fixed to specific request priority...so it ended up being a bit more complicated than I had originally envisioned but once I sat down and thought about it and started writing the code, it wasn't all that hard (just a lot of code). DMA was just a pain but one good side effect is that I created a 1KW(*) FIFO for DMA transactions and the DMA state machine will run as long as there is data in the FIFO. This means that the J1 only has to deal with DMA at the start, end or when the FIFO needs refilling rather than on every word. The DMA also has a programmable "delay" so that it won't swamp the Unibus and starve the PDP-11 CPU. For the RF11 (the only DMA device on the MEM11) this will typically be set to the original transaction speed of the RF11 disks (for 60Hz machines that would be a word every 16us or 19.2us for 50Hz machines). There are configuration settings in the RF11 emulation that specify the rotational speed of the RF11 disks as well as the DMA transfer delay. I'm now off to start writing a bunch of test cases for the various blocks so that I can start to simulate the design. Once I'm happy with the simulation results, I'll start to create the schematic for the MEM11. Because I'm so tight on pins (I'm using 129 out of the 158 I/O pins), I'm having to use some of the "multi-function" pins. The main implication is that I might need to use a small CPLD so that I can switch between the different functions. The main set of multi-function pins that I have to use are the ones used by the FPGA to load it's bit-stream on power on reset. This is an understood problem and isn't something that I have to worry about now. The only impact will be in re-assigning pins so that low speed I/Os (LEDs, and sense jumpers) are only shared with those pins. I'll post another status update once I've made some significant progress on the simulation and testing. TTFN - Guy (*) The reason that I chose a 1KW FIFO rather than something smaller is that the "block RAM" in the FPGA comes in 18Kbit "chunks". So the easiest course was to use one of them configured as 1K x 16 (I'm ignoring the 2 "parity" bits in the "block RAM") as the memory for the FIFO. Since I'm using less than half of the "block RAMs" (all of the other used "block RAMs" are used for the RAM for the J1) I can make the FIFO substantially larger if I need to.

Then & Now

by c.murray.mccullough＠gmail.com

The microcomputer market back when classic computers were the in-thing saw $1000 machines ; software costing $10s or $100s. Today hardware-wise $500 buys a powerful machine while many apps/programs are free or cost in the low $10s. Todays machine are 1000x maybe a million times faster. Interesting history for machines we love! Happy computing. Murray :)

Apple Lisa I/O board diodes

by witchy＠binarydinosaurs.co.uk

Hi folks, 'Decaying battery' panic led me to unearthing my Lisa 2/5 to check the state of the batteries on the I/O board since it hadn't been out of its box or powered up since 2005. Fortunately the damage is very minimal and is only restricted to track discolouration and external rotting of one particular diode which I can't find mention of on my schematics. Anyone with a 2/5 care to check their I/O board for me please? The diode is D8, just above the battery location. It's in the board in such a way as to make its markings pretty unreadable in the pictures I took before cleaning, but it's the only white diode in the machine and I'm guessing it might be a 5.6V 1N4734A based on what I can see. Fortunately it still works for now, 0.7V voltage drop. Pic of the board before cleaning is at http://www.binarydinosaurs.co.uk/LisaIOBoard.jpg Cheers! -- Adrian/Witchy Binary Dinosaurs creator/curator Www.binarydinosaurs.co.uk - the UK's biggest private home computer collection?

well... the trick is to have book partially open not cracked and to have 2 cameras for fast production copy and uniform size on the size as cameras are fixed clear material flattens pages sure if just a page or so a camera even hand held works... but if you are humping pages all day long..... you need this thing!

...And when you look at the site you will see guy in dust mask. when scanning fungus ridden or moldy material a must although I prefer a class A respirator.

If another copy shows up and/or someone scans a copy then the ucccky held copy is discarded. If not at least a copy is saved here and sometimes we suit up and scan some of it. Ed Sharpe archivist for SMECC In a message dated 2/19/2016 12:21:24 P.M. US Mountain Standard Time, cisin at xenosoft.com writes: >> http://www.diybookscanner.org/ :) > Ooh, that's pretty cool. Yes, but, . . . I've participated in building a few similar devices. Instead of the two sides MEETING in a V, there should be an open area right at the spine to accomodate the greater thickness of the spine itself. Having the two side panels able to slide up and down, with pegs, a few inches would accomodate that and permit a varying amount of spine clearance. Lighting. Ideally, lighting for copy work should be at a 45 degree (1/4PI) angle. That way specular reflection (glare) from glass cover (still needed occasionally!) or even just glossy paper, is not going towards the camera. If the trough faces north/south, then that can be done with light(s) north and south of the unit. Using two lights makes it much easier to get acceptably even illumination. Some people prefer various forms of diffuse light, or coaxial lighting ("ring" light). Having the camera at a fixed position relative to the work holder is great IFF you are doing consistent size. Different sizes could be dealt with through variable focal length ("zoom") lenses, but that is not always the ideal solution. I like to use FLAT-FIELD lenses, which are generally fixed focal length (sometimes called "primary lenses"). Enlarger lenses are an extremely cheap source for those. Being able to move the camera/work distance closer/farther requires a movable mount to change distance, but keep the camera centered relative to the work. North/south motion can be easily handled by moving the book along the trough, preferably with a fence, or simple bench-dog stops. The other motion generally requires the camera mount to be a pole at a 45 degree (1/4PI radians) angle relative to the work. Since the work is at a 45 degree angle from vertical, that means that the pole can be VERTICAL, with the camera mount aimed at a 45 degree angle. The post should be offset slightly from the north/south center, with the movable camera mounts holding the cameras at 45 degree angle (preferably with the focal node close to that central plane). Positioning of the book would require placing it so that it is centered north/south (calibration marks, as well as fence or bench-dogs, are very helpful!) and moving the camera up and down and focussing for distance. NOTE: use of other than 90 degree (1/2 PI radians) for the book holder would require further changes! -- Grumpy Ol' Fred cisin at xenosoft.com

BDV11 'mis-feature'

by jnc＠mercury.lcs.mit.edu

So I recently discovered that the LTC feature on the BDV11 bootstrap board has a minor issue: the latch that stores the 'LTC enabled' bit is _not_ cleared by INIT (unlike every other PDP-11 device I've ever heard of), but only by a direct store into the LTC CSR, _or_ power cycling (BDCOK, to be exact). This means that once you turn the LTC on using the BDV11, neither an INIT instruction, nor a 'Start' command to ODT, will disable it! Needless to say, it tends to scramble the booting process when an LTC interrupt shows up before the software is ready for one... I _was_ going to ECO the board, to connect BINIT to the clear input of the latch, but... I now think I know why DEC did this. There is no bus receiver on BINIT! (And there is, alas, no empty DIP space I could put one in.) I'm seriously tempted to connect the 'reset' circuitry on the BDV11 to BINIT, instead of BDCOK. That would mean that hitting the reset switch on the BDV11 wouldn't emulate a power cycle any more, but maybe I could live with that - I never use that switch anyway. And it would be _so_ nice to have 'Start' disable the LTC... Noel

IBM 3101-12 ASCII terminal - need fuse holder

by ethan.dicks＠gmail.com

Hello, all, I was just gifted with an IBM 3101-12 ASCII terminal that happens to be missing the fuse and fuse holder. Unlike a lot of 1960s and 1970s gear, it's not round. It's square. Is this a standard IBM thing from the 70s/80s? Anyone know where I could get one? It seems to snap in and probably fell out at some point under its previous owner. Also, I found only a little info on it from Googling. Later IBM ASCII terminals emulated ANSI command or Wyse-50 or something. I couldn't find anything on the 3101. Is it a glass TTY or does it respond to any cursor positioning, etc. commands? Thanks for any tips and info. Worst case, I can bodge in a fuse on the inside, but if I can find a replacement holder, I'd like that more. Thanks, -ethan

Anyone have DIBOL-11, CTS-300, or CTS-500?

by spacewar＠gmail.com

Does anyone have the DIBOL-11 software, which was packaged for RT-11 as CTS-300, and for RSTS as CTS-500? My immediate interest is for RT-11, though I have a DECdatasystem-570 that I believe was originally sold with CTS-500, so it would be really nice to get that as well. It would also be nice to get scans of related documentation, if anyone has it, including: AA-5519A-TC Introduction to CTS-300 and DIBOL AA-5697E-TC CTS-300 Release Notes and Installation Guide AA-5495A-TC CTS-300 Concepts and Facilities AA-1760F-TC DIBOL-11 Language Reference Manual AA-5972D-TC DECFORM User's Guide AA-5025B-TC CDS-500 DIBOL User's Guide

Hello Henk, thanks for the link. It talk about two boards (one hex and one quad). In effect mine are hex and quad. But the hex board has three IDC connectors, while the quad only two. My suspect is that the third connector could go to some other module. Do you have the VT30-H system too? Could we compare the boards? About documentation: I can't find the Option Bulletin cited on the text. Thanks Andrea

PCS Cadmus/QU68000 systems

There is a short blurb about them on de:wp (https://de.wikipedia.org/wiki/Cadmus_Workstations) saying the PCS QU68000 were based on (who'd have guessed...) a 68000 processor on a QBus (!) while the later models sold under the CADMUS trademark held 68020/030 and, from 1985 on, MIPS RISC processors. They ran MUNIX, a V7 UNIX derivate, with some quite sophisticated cluster integration (network boot, "Newcastle connection" common superroot namespace, networked block devices) enabled by a board called the Intelligent Communications Controller. The outfit even still seems to stick around here (https://www.pcs.com/en/company/history/the-history-of-pcs/), albeit manufacturing access/time registration/industrial data terminals nowadays. As usual, if somebody from Germany conducts an operation on those and doesn't know where to put all of them, I'm willing to help out with collecting and re-homing. (I may also have an opportunity to collect a couple of them in the Netherlands if there are any left by/can be held onto until end of May 2016. I'd wish for one of each significantly different type but this is not a reservation but a "last resort" deal if they'd go to trash otherwise. Basically, if anyone else comes along offering a good home for them, I'm happy to stand back.) TIA, Arno

Old MOS Mask-Programmed ROM forgetfulness?

by rickb＠bensene.com

Hi, all, I have a question about old Mask-Programmed ROMs The part in question is the National Semiconductor MM5231. This part is a 2K-bit PMOS Mask-Programmed ROM, generally organized as 256x8, but also can be organized (via a MODE pin)as 512x4 bits. In this particular application, the parts are used as 256x8. I'm wondering if anyone knows if these particular ROMs (from the '72 timeframe) have a tendency for bit rot over the years? I know some of the early MOS ROMs had issues with metallization creep that would cause data loss/corruption. I have an old calculator that uses these ROMs as the micro and macrocode stores. The machine is catatonic, though the power supplies, master clock oscillator and divider circuitry, and the other obvious stuff are OK. I suspect it is probably stuck in some kind of microcode loop, just cycling around doing nothing. I have not yet put logic analyzer on the microcode latches yet, but that's probably my next experiment. Sadly, if one or more of these ROMs (there are 18 of them!) has failed, it likely means that the machine can't be restored to operation, as this is quite a rare machine, and there just aren't many of them left around. I have three different EPROM programmers, but sadly, none of them have the capability to read these parts. I was I had a Data I/O programmer, but alas, haven't come across one with all the Unipak modules I'd need at a price I can afford.

Couple of Xerox 6085 questions

by tmfdmike＠gmail.com

1. Anyone who has played with Xerox systems will have encountered the dreaded 0937 code at boot time; it means "I have been configured for network operations. I abjure the world and will wait until hell freezes over before continuing the boot - unless I get the time from a network time server!" This is inconvenient and frustrating at times. Netware IPX/SPX is basically Xerox XNS implemented pretty much unchanged; does anyone happen to know if a Netware server can provide network time server functions - and in a way that a Xerox workstation would grok? 2. I haven't powered up my 6085s in a long time - at least 5 years; maybe 10 for some of them. The results have been most disappointing. They won't even *start* POST - and/or they give a rolling screen with no sync - and/or a blank screen - and/or they pass POST but won't boot with an 0151 error. I've tracked these down in most cases to flaky IOB boards. These boards hold the system PROMs. Anyone else seen similar issues? Could it be bit rot in the PROMs? Is that a known thing with 6085s? Thanks Mike

Tool to convert between Motorola FFP and IEEE754 float formats?

by classiccmp＠philpem.me.uk

Hi, Does anyone know of a tool which can convert between Motorola's FFP (Fast Floating Point) float format and IEEE754? I'm trying to reverse-engineer some ancient 68k code which uses the FFP library, but a load of the floating point constants have been hard-coded as hex constants, which is making things hard to interpret... I've tried to convert the 68k assembler in FFPIEEE.SA to C, but I must have missed something because it just isn't working... Thanks, -- Phil. classiccmp at philpem.me.uk http://www.philpem.me.uk/

Stuck bits on 11/73 Clearpoint 4MB memory - how to repair?

It's not clear that that's really a hardware problem. DEC makes assumptions about how many memory CSRs there will be, etc, and some third-party board 'fail' when they don't meet those expectations. I have a Clearpoint QED1 (I think that's the one, didn't check) that does that. > What I assume is the parity light on the third party "Clearpoint QRAM-2 > SPB-1 88B" lights during self test.

I would tend to use diagnostics as 'help', not my main tool in diagnosing faults. This is particular true as really bad issues can prevent the diagnostics from loading/running, so if you get skilled at fault analysis without depending on them, you're better situated to deal with the failures that prevent using them. > Can anyone offer hints as to how to identify which component is broken > and how to go about repairing this? As other have said, lacking the prints, pulling chips (if they are socketed) ought to enable you to work out which chips goes where. (I'v worked out the chip layout for a number of un-documented memory cards this way.) I don't know about your 88B, but the one I have photos of, and my other Clearpoint cards, the chips are in sockets. With luck yours will be too... If not, ask if someone has one with sockets (alas, I don't have an 88B), who can do the mapping for you. Important: once you have worked it out, pass it along! I'm trying to upload all the data I've collected about cards for which no documentation is available to the Computer History wiki. > It's the only memory board in this machine, so I guess the problem > might actually be a bus or processor board, right? Could be. I have an KDJ11-B which has stuck bits, and that's the CPU board, so yours could be to. > I have no other q-bus memory to test with, so can't do swapping / > process of elimination to be sure. It's definitely worth having another small QBUS memory card to use in fault isolation when debugging. M8044's are readily available on eBay for about $20. They are only Q18, so not usable in the same machine as Q22 memory, but they are useful for debugging. I would definitely invest in one. (If you luck out and get a bad one, send it to me, and I'll swap it for a known good, tested, one. I've fixed a whole bunch of them, got to the point where the last one I did for someone I didn't even have to pull out my 'scope! I could tell from the symptoms exactly which chip to replace! :-) > From: Jay Jaeger > Well clearly it is only affecting certain address bits - or the > diagnostic would not run at all Well, like I said, I do have a KDJ11-B which will run the on-board startup diagnostic, but which has a bit stuck hard on the QBUS interface! So those machines seem to be pretty resilient. Although as you point out, if he can load and run the diagnostic, it's probably not the CPU. > note that it is starting at 010000000, so that points to the memory Yup. If some locations work, and others don't, it's almost certainly the memory. And since he's only dealing with a single memory card, it's probably not the bus drivers/receivers on that card, either. One can use ODT on the KDJ11-B to poke around, and find the envelope of the problem. (See comments above about not relying on diagnostics! They are better for saying something's busted, than for accurately telling what _is_ broken.) With that, and a chip->memory map, it should be fairly easy to replace the offending chips. Noel

So here's a quick update on where Dave Bridgham and I are with the QSIC, since I think we have reached a significant milestone. We have the first of two wire-wrap prototype QBUS motherboards more or less (see below) done, and working to do slave cycles on the QBUS. (I.e. we implemented a simple register, and can write it, and read the contents back.) A test program to write all 2^16 possible values, and read them back and check them, ran several thousand complete passes with no errors. To get there, we (Dave, really - he bore the brunt of the work on this problem, and finally conquered it) had to tackle and fix some major noise issues: the way the prototype is done (a wirewrap QBUS mother-board with bus transceivers, level converters, etc, connected to an FPGA prototyping card with flat cables), we think we had cross-talk problems in the cables (since the connector pinout on the FPGA card, which we can't change, didn't alternate ground and signal lines). Anyway, it's working now; that means the hardware is 'mostly' working; most of the work from here on out will be FPGA, etc, programming. There _are_ a few additional QBUS lines used for bus master (DMA) and interrupts which we haven't used yet, and one of the first things done now is to get those two kind of bus cycles working; a) we have to get them done anyway, and b) that will verify that the QBUS interface hardware is full working. With that in hand, we can do the first controller (RK11), using memory in the FPGA to simulate a small disk. We'll then try and get to the larger RAM on the FPGA, to do full-size RAM disks. Next up after that is probably to hook up some SD cards (we already have produced the small PCB daughter-cards, which will mount on sockets on the wire-wrap mother-board, to hold the SD cards - we still need to add those sockets and wire them up, hence the comment that the wire-wrap mother-boards are "almost done"), at which point we'll have a fully-functional prototype. Dave has also produced prototype PCB's for the indicator panel, and one has been stuffed, and Dave's about to try and hook that up, and get it running; that will require yet a bit more work on the mother-board (install 3 sockets to hold the driver chips for the signal lines in the interface to the indicator panel). Blinkenlitz are a priority because, i) just because ;-), and ii) being able to display data from inside the FPGA will be a big debugging help. Anyway, we think getting slave cycles working was a major milestone (for a couple of software guys :-), And we think (_hope_ :-) that progress will now be pretty rapid, so hopefully more soon. Noel

Front Panels Update

by rodsmallwood52＠btinternet.com

Hi I had an email in from the screeners this morning. She is getting there. I suppose I should not expect automation speeds from a skilled hand process. Twenty boards not all the same with five passes per board, flush out time and drying time with the need for spot on registration aint gonna be that quick. More news as I get it Rod

IBM System z9 available near Ann Arbor, MI

by scaron＠umich.edu

Hi all, I was stopping by a local recycler to pick up a few Cisco switches I bought to add to my lab, and while I was there, I happened to spot a complete IBM System z9 machine out of the U-M Health System. http://www.ebay.com/itm/IBM-Type-2096-S07-System-z9-Enterprise-Server-TESTE… The fellow that I was speaking with indicated that they might accept a little bit less than the tagged price. Perhaps this is a bit on the new side for the list but I figured these don't come around too often and this might be a good place to find it a home... I know there are lots of IBM enthusiasts here. Best, Sean

pdp11/04 : the pics....

by jdr_use＠bluewin.ch

On ftp.dreesen.ch/PDP11 you can find some pics on how the rescued PDP11/04 fits right in next to its cousin, a PDP8/a This 8a, BTW, has more memory (128K x 12) and more oomph ( a FPP8A ) than the PDP11/04.... Jos

Stuck bits on 11/73 Clearpoint 4MB memory - how to repair?

by jacob.ritorto＠gmail.com

Hi, Seems I have bits 4 and 3 sticking on my Clearpoint QRAM-2-SAB-1 88b 4MB memory in my pdp11/73. Can anyone offer hints as to how to identify which component is broken and how to go about repairing this? It's the only memory board in this machine, so I guess the problem might actually be a bus or processor board, right? I have no other q-bus memory to test with, so can't do swapping / process of elimination to be sure. Here's the manual: http://www.arclightindustries.com/docs/Clearpoint-88B.pdf (which I probably should add to manx or archive.org or something). Here's a snippet of the VMJA diags run illustrating bits 4 and 3 sticking. During the next VMJA run, all addresses were showing up as errored instead of just the ones ending in xxx000xx, so I guess it's getting worse! @173000g Starting system BOOTING UP XXDP-XM EXTENDED MONITOR XXDP-XM EXTENDED MONITOR - XXDP V2.5 REVISION: F0 BOOTED FROM DL0 124KW OF MEMORY NON-UNIBUS SYSTEM RESTART ADDRESS: 152000 TYPE "H" FOR HELP ! .R VMJA??

IBM 3290 terminal

by kevin.bowling＠kev009.com

I'm looking for an IBM 3290 to complement my z800 mainframe and third party 3174-22L establishment controller. I can't imagine these were particularly rare, but am sure many of them have been destroyed in the waning years since it takes special equipment/know how/desire to even use. Any leads on on for a reasonable price? Regards, Kevin

Yes, it was a > bit tight on memory, but we got a LOT done on that machine. As I mentioned our first 11/750 was delivered with 512KB (we upgraded it pretty quickly to 8 boards for 2MB, where it ran for years). The 11/750 first shipped with IIRC VMS 2.0. My first encounters with VMS was around mid-1984 and VMS 3.4. We had 8MB of memory in our second 11/750 but it was supporting 50+ users. That 11/750 went off-lease, we sent it back. That's why I had to upgrade the other one, so we'd still have an 8MB VAX in-house. It ran VMS 4.7 at the end of its days 23 years ago (we had quite a bit of software that wasn't available for/wasn't licensed for/wasn't under paid-maintenance for 5.x). I haven't powered it up since we left that building (I do occasionally power up the 8300 that we got for product development). So I'm fairly confident that 512MB is enough for VMS 2.0 but I _think_ by 3.0, you had to have a megabyte or two. 1.25MB would be the most you could stuff in a 11/730 if you could use the boards populated with 16Kbit DRAMs. I don't think VMS 2.x runs on an 11/730 (but I could be wrong there). We ran Ultrix 1.1 and VMS 5.0 on one of ours (with 5MB). VMS 5.0 barely fit - we mostly used that to link our product binaries under 5.x for distribution to our customers. I do know someone in Ohio who ran VMS 5.0 on a VAX-11/725, but they did it by cutting a slot in the skin and running a BC11 cable out to a BA11 box next to the 11/725 and stuffing a UDA50 in the BA11. With an external disk, there's no practical difference between an 11/725 and an 11/730... same CPU, same backplane, same memory... just a packaging difference. -ethan

Emulex QD32 Format Program

by jacob.ritorto＠gmail.com

Does anyone still have a copy of the "Emulex LSI/PDP MSCP Formatter Program (SXMX8B) ? My QD32 emerged from storage in a foul mood and is giving me errors I don't understand when I use the manual entry methods for inputting geometry and issuing a format. From what I can tell, it's complaining that its onboard RAM is bad. Comments / suggestions welcome. thx jake

Dumb terminals and many sessions (was Re: VAXen and minimal memory)

I have no doubts that was true when selling systems, but I remember seeing the paperwork from when we were growing, so 10 new employees meant 10 new terminals (and sometimes one more CS21)... Eventually, we stopped growing, then started shrinking, so it was feasible to log into two systems at once by having two terminals on your desk. We also had structured wiring from Nevada Western (DB25 modular adapters on each terminal, 6-pin silver satin cables to the wall, and several 3U "switchboard" panels with blocks of jacks and 25-pair telco cables back to the VAXen) so it was also easy to employ 2-line switch blocks at our desks. Eventually, we had "modern" terminals like the CiTOH 101e that supported a second session over the "serial printer" line (we never used the second line for hardcopy). Now, I use computers with bitmap screens to maintain multiple simultaneous character-based sessions. Same workflow, less wire and fewer large hunks of plastic and metal on my desk. -ethan

11/73 into 11/03 chassis?

by jnc＠mercury.lcs.mit.edu

> From: Jacob Ritorto > Would you happen to have notes or references about how to do it? It's not too hard; basically, one has to wire pins BC1, BD1, BE1 and BF1 (BDAL 18-BDAL21, respectively) on all _QBUS_ slots together into a bus. So wire BC1 on slot 1 to BC1 on slot 2, slot 3, etc, etc. A couple of notes: First, I said '_QBUS_' because if you have a Q/CD backplane, clearly one doesn't run the extra BDAL lines to the CD slots, only the QBUS slots (which run down the left-hand side, when facing the backplane). Second, for optimal analog behaviour, the 'out' slot on the backplane should be the last slot you wire to, so that there are no branches in the transmission line for BDAL18-BDAL21 (which can produce reflections - aka noise - on the transmission lines). How to do this efficiently (in terms of the wiring) can be a bit tricky, depending on the backplane configuration. E.g. if one has the standard 'serpentine' backplane, i.e. one with the slots in the following kind of order (facing the backplane from the board side): 1-2 4-3 5-6 8-7 9-10 etc., one might naively think one has to run the extra bus lines back and forth to match. However, only the _grant_ lines have to follow this pattern (and they are already there); the added lines don't have to follow the same pattern, as long as there are no branches. So, for the example 5-slot backplane above, one could/would wire: 1-4-5-8-9--2-3-6-7-10 i.e. a single vertical run on the left hand side, a single diagonal from 9 back to 2 (shown with "--"), and then another vertical run on the right hand side. Much simpler than wiring back and forth in slot order; there are no branches; and the last slot is the 'out' slot. For backplane with an _even_ number of layers, e.g.: 1-2 4-3 5-6 8-7 it's a little more complicated: a single vertical run on each side cannot be connected in such a way as to have the 'out' slot (8) be the last slot. One has to do something a little more complex: 1-4-5--2-3-6-7--8 with a vertical run on the left side, stopping short of the last slot; then a vertical run on the right side, then a lateral back across on the last layer. Obviously one _could_ run the wires back and forth, in slot order, but that will take a lot more wire, which at the very least is more work (especially on backplanes which don't have full wire-wrap pins, just the little stubby pins that have to have the wires soldered to); whether it also increases the delay down those transmission lines enough to be noticeable is something I don't know the answer to. All the obvious caveats apply: make sure not to get confused by the mirror pin and slot numbers on the front and back sides (you'll be wiring on the back, whereas the diagrams above are on the front), etc. Noel

Odd 11/23 (?) ROM carrier

by jnc＠mercury.lcs.mit.edu

Anyone know what this: http://www.ebay.com/itm/251526917058 is? It has five chips, not six, so it's not the KEF11-BB CIS option. I've tried Web searches on "57-27889-01", but not turned up anything useful. Noel

Good memory board for Heath H-11?

Then, since you are missing only 4kw out of the maximum of 28kw (which is the normal maximum), you will not likely have a problem unless you have really memory rich programs. RT-11 runs fairly well in just 16kw (or 32 KB), so it should not be a problem. For my own work in which I need to run MACRO.SAV as fast as possible, I run the program in 64 KB of extended memory under a Mapped Monitor - which a PDP-11/03 (or an LSI-11) can't do since there is no MMU chip. Of course, my actual CPU is a Pentium III which I use to run Ersatz-11 so that RT-11 is running 15 times as fast as a PDP-11/93. And the disk I/O is also a bit faster. I can copy a 32 MB RT-11 partition to a second 32 MB RT-11 partition in under 2 seconds. Even with two ESDI hard drives on a PDP-11/93, that takes over 4 minutes. Jerome Fine

Good memory board for Heath H-11?

I have not opened up ours yet but I always assumed they were all DEC boards. Ed# _www.smecc.org_ (http://www.smecc.org) In a message dated 2/9/2016 7:36:05 P.M.

From my prior experiences with DEC (an 11/34a many years ago; now at the RI Computer Museum), I know my way around the field guide?but I? m having trouble trying to identify the correct module number suitable for the LSI-11 CPU. Even though it?s a Heath machine, I assume it?s module compatible with DEC. Any help would be appreciated. Thanks! > > Rich Maybe an M8044 MSV11-D (no parity) or M8045 MSV11-E (parity) would be most appropriate.

AIX for IBM PS/2

by ball.of.john＠gmail.com

>Good luck in finding media for AIX PS/2. As far as I know, it was never released on >CDROM and the last version I had was ~53 3.5? floppies (long gone now unfortunately) >and *only* worked on specific PS/2 hardware (no BIOS ? all drivers went straight >to the ?metal?). > >TTFN - Guy Nope, AIX 1.3 is readily available. It's over on http://ps-2.kev009.com if you know where to look along with a rather massive amount of documentation and (VERY HANDY) installation instructions. I can confirm that it will work on a stock IBM 8580 and you can get several different flavours of window system if you wanna roll that way. I put a video on Youtube a few years ago of a running machine when it was still rather badly configured. I briefly had it working on the model 55SX as well but because I was not labling the disks as I wrote them I went out-of-sequence somewhere and frustratingly couldn't find Disk 15. -John
