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?

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

For me at least this throws into question the whole "...the 10 first came out with the 5 in1972..." story everyone repeats over and over, unless one must have a "10" printed on the console in order to accept a computer model's existence.

Hoping some here will check for themselves and consider it misleading at least to simply call the original PDP-11 a "pdp 11/20 without the nameplate". In short, the original bare-bones pdp11 was the pdp-11 10, the fully-equipped version was the pdp-11 20. Why DEC temporarily dropped it's pdp-11 10 model from the product line and >from newer price sheets I can't say. Certainly the "10" was gone when DEC rebranded their front nameplates to read "pdp 11/20". I believe the 1969 brochure is on bitsavers, or I think my website has a copy you can download.

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.

Hi, I'm looking for the schematic for a PA68-F. It's a two high collection of single width M series modules that implements the paper tape high speed reader/punch control for positive bus machines. I found a Typeset 8 document that describes the maintenance for the beast but not the schematics which are apparently in Dec document A-ML-PA68-F. Does anyone out there know where I can download this document? Thanks, Marc

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 :)
