Does anyone know if an ECO exists to convert a REV11 board (M9400) to 22-bit, in the same way that an ECO exists to convert BDV11's to 22-bit? (On the BDV11, there's a resistor pack with 4 unused pull-up/down pairs, making it a really trivial ECO.) Noel

ICL Quattro

by supervinx＠libero.it

Hi! Does someone have some links or manuals about the ICL Quattro model 49 PC? I serviced the PSU, but have no response from the serial ports on the back. Can't say what the port numbering is and if they are DCE or DTE (I assume 9600,8,N,1, may be I'm wrong...). Thanks! -- Vincenzo (aka Supervinx) --==ooOoo==-- My computer collection: http://www.supervinx.com/Retrocomputer --==ooOoo==-- You can reach me at: www.supervinx.com www.facebook.com/supervinx http://www.youtube.com/user/supervinx http://www.myspace.com/supervinx

PDP-11/23 Debugging

> From: Ben Sinclair > It halts back to ODT at 00104 Depending on how the vectors are set up, that could be an unhandled clock interrupt. Common practise is to set the vectors at X to point to X-2, and put a HALT instruction in X+2. 0100 is the line clock interrupt vector. > there is a strange modification...

I have no idea > what that might be Maybe the electrolytic failed, and the person couldn't find the right size replacement, so used two smaller ones in parallel? > When I run the program, it halts at 000014. That means it trapped through location 010 (illegal instruction); the vector there points to location 012; it executed the HALT instruction at 012, and stopped with the PC containing 014 (the location of the next instruction - see the description of the HALT instruction in most versions of the PDP-11 processor manual). To find out the location of the illegal instruction, you need to look on the stack: R6 (the SP) will point to to top of the stack, and the PC and PS at the time the illegal instruction were seen will be the top two things on the stack. (I forget whether they are in (SP) and (SP+2), or (SP+2) and (SP+4). And I forget whether the saved PC is the address of the bad instruction, or if the PC has already been incremented to point at the next instruction.) But I'm not sure that's really going to tell you much. If it's a hardware flaky, the fault may be happening on a perfectly good instuction. > the error address should be in R1, which reads as 004330. I did try and > write to that location, and it reads back fine. But if you trapped through 10, that's not caused by that memory location being a problem. > I'm confused though, because it halts at 000014, but that program > doesn't have an instruction at 000014. .. I would have thought it would > halt on some location that actually had an instruction. After a HALT instruction, the PC points to the _next_ instruction after the HALT. So the HALT was at 012. > What exactly does the aux switch on the front panel control? I assumed > it was power to the AC plug on the back of the machine, but it must do > something else. Well, it depends on what model of box you have, and how it's configured, but on standard DEC LSI11 boxes (the ones with three switches; Restart, Run/Halt, and Aux), the Aux can be configured (and normally is) to turn the Line Clock off and on; the Aux power thing is an optional behaviour. That would definitely fit the symptoms and behaviour you describe. > From the documentation, I don't see that it does anything other than > control that AC plug. There's documentation somewhere (don't recall off the top of my head - it won't be in the processor card stuff, it will be in the box documentation) about how to configure the Aux switch. Basically there are some jumpers on the PCB in the front panel. Noel

MCT Serial board mystery - Can you crack the pinout code?

by drlegendre＠gmail.com

Decided to take a good shot at putting my only S-100 serial board to use. Figured the place to start was ID'ing the connector pin-outs so I could set up a cable and begin the process. Lacking any docs whatsoever, all I could do was trace out the PCB and try to ascertain what was what. So here's what I've come up with - can +you+ figure out which pin is which? Board has two outputs, J1 & J2. They are standard 10-pin DIP headers, using the standard numbering scheme. We'll look at J1; J2 is essentially the same, but routes to different pins / chips / transistors. Pin 1 - Col. of 2N3906 (Base is driven by opt. 2 of 1458 - see Pin 7) Pin 2 - Pin 28 (DB3) of both 1014 & 1015 UARTs Pin 3 - 1K pull-up to Vcc (12V? Same Vcc as 1458s) Pin 4 - 150R -> 47R -> Pin 6 w/ XNOR input 1A at 150/47 junction Pin 5 - n/c Pin 6 - 47R -> 150R -> Pin 4 w/ XNOR input 1A at 150/47 junction Pin 7 - 1K2 -> opt. 2 of 1458 (see Pin 1) Pin 8 - GND Pin 9 - 1458 opt. 1 Pin 10 - GND So we have what looks like three (3) each Inputs & Outputs, plus a Vcc and GNDs: Inputs - Pin 2, 4, 6 Outputs - Pin 1, 7, 9 Vcc - Pin 3 Gnd - Pin 8, 10 So.. what do +you+ make of it? =)

pdp11/93 DB9 rs232 pinout

And the '93' manual you list is not for the 93, but rather is for the KDJ11-E CPU card, which is used in _both_ the 93 and 94. (That document is also mostly duplicative of the 94-MG.) Needless to say, there's a lot more to those systems than the CPU card, although some of it (e.g. the power supplies) _may_ be documented separately; I haven't checked. Typical DEC systems have a lot of other documents, none of which seem to be available online for the 93/94, including (typically): User Manual Technical Manual Maintainence Manual Field Maintainence Print Set Illustrated Parts Breakdown For the KDJ11-E there does seem to be the "KDJ11-E CPU System Maintenance Manual" (EK-403AA-MM-001), but that doesn't seem to be available online. The one 11/94 document I know of (the System User and Maintainence Guide) does reference the Field Maintainence Print Set for the 11/94 (MP-02637-01 - but according to Manx, that's not available online), and the IPB. So probably the other ones don't exist for the /94. I don't know which of these documents even exist for the /93, since I can't find a single 93-specific document - which might list what other /93 documents exist. Noel

> From: Roe Peterson > Can anyone point me at the pinouts for the KDJ11-E pdp11/93 DB9 rs232 > connectors for the extra 7 (simulated) DL11s? Alas, documentation on the 11/93-94 seems to be very scarce on the ground. (And, just for grins, the page in the 11/94 User Guide which has the section - 1.2.6 - which talks, however briefly, about that panel - pg. 1-4 - is missing >from all the online copies of that manual which I checked.) The only thing I can suggest is that if you actually have the cable, the pinout on the board is given in the KDJ11-E User's Guide (EK-KDJ1E-UG-001, available online), on pg. 88-91 (aka 2-13 to 2-16), and an ohm-meter and some time will give you the pinout of one of the DB9's - presumably they are all the same, from there.

XT keyboards (and missing decal)

by jules.richardson99＠gmail.com

Hi all, I've got a 5160 here with the XT keyboard - however it's got the 64/256K motherboard fitted (with the "early" Jan '86 EPROMs), and Wikipedia seems to claim that by the time the 64/256K boards came out the machines were shipped with 102-key keyboards (the XT flavor of the Model M, I assume). Anyone know if that's true, and so my system should technically have a "full size" keyboard, or was there a crossover period where systems with the newer boards shipped with the 83-key XT keyboards? Everything else about the machine suggests it was built sometime '86 (dates on the PSU, IC date codes on the expansion boards etc.), although it has a 20MB F/H IBM hard drive (rather than the H/H Seagates that I think the newer systems got). There's no ID info on the underside of the keyboard like there is on my Model M; I'm not sure if there should be. Also, I'm missing the silver keyboard decal - I believe these just said "IBM personal computer" like they did for the 5150, even though the 5160 case decal mentions XT. Does anyone have one they could pull from an otherwise-junk keyboard that they might be willing to part with? cheers Jules

Kearney & Trecker Core memory, may be PDP8

by jws＠jwsss.com

I can't tell for sure, but this auction may be for PDP8 core board. KT-KEARNEY-TRECKER-ASSY-KT83-0933-KT84-020-SYSTEM-BOARD http://www.ebay.com/itm/181565552717 board is 6 across in size. From what I could find out K&T used PDP8 for NC controlled machines at some time. There is also this sort of board. The silkscreen shows a Microprocessor section outlined with a 40 pin ceramic gold chip. I am going to query the vendor to get a picture where you can read what is on the can, or get the text on the can. Maybe the thing is a Harris part, don't know. Since the listing is for Giddings and Lewis, which is either a subsidiary or competitor of K&T it may be another completely different system. It looks like K&T, G&L and Cincinnati Millacron had a number of legal runnins as there were several lawsuits in the google hits when looking these boards up. CM used an OEM Microdata 1600, and later 3 generations of their own 1600 derived designs before moving on to other newer microprocessor scale parts. The CM 800, and 900 and one later are all 1600s, or near relatives os such. The 900 uses 8K, 16K microdata manufactured core boards, and also the Ampex / CDC 32k core board. I buy all those that show up cheap on the usual auction site. Here is the processor board: GIDDINGS-LEWIS-KT-KEARNEY-TRECKER-871-20410-05-SYSTEM-BOARD http://www.ebay.com/itm/181564464339 Jim

> From: Henk Gooijen > I wanted to connect a VT510 to the console port. All connectors are > DE-9 Really? The PDP-11/94-E User Guide (EK-PDP94-MG-001), available online in a number of places, shows (pg 46, aka 2-18) the Console/SLU panel, and the Console connector is much larger than the SLU connectors. (The illustration shows a 23-pin D-type connector - presumably an error, it should have been 25.) And here: http://www.pdp-11.nl/pdp11-93/rear-panel-small.jpg is a picture of one, and it indeed has the 25-pin console connector. Although I suppose it's possible they changed the actual hardware at some point, and some real machines have a 9-pin D-type? Or maybe a VAX of some sort uses a similar panel, but with all 9-pin D-types, and someone had stuck on of those on that machine? > What worked for me is the "VAX console cable", in other words: that > DE-9 connectors is NOT "PC alike"! You can find the VAX console cable > pinout on the web. Good catch! It makes sense that the VAX and 11/93-94 use the same 9-pin D-type pinout; that way they'd only have to have one kind of cable.

Non-CRTC PET video circuitry...

by derschjo＠gmail.com

Yet another "oh, let's spend an evening doing a small project" that's ballooned into a major undertaking: I thought I'd try my hand at getting my old PET up and running again; this is an original "chiclet" keyboard model (with 6550 RAMs and no CRT Controller chip). There are a multitude of problems with it (the CPU isn't resetting, I'm sure there's bad RAM and ROM) but I thought I'd start with the most obvious fault -- the video generation. Here's a picture of what it's currently doing (sorry it's not very good...) : http://yahozna.dyndns.org/scratch/pet/oneline.jpg It's only drawing a single line of characters (garbage with some noise due to a very terrible socket holding the character ROM), centered vertically. I initially thought this was a VRAM addressing issue (a stuck counter or whatnot) but it turns out the VSync signal is much too fast -- it's only about 1.2ms long (it's supposed to be about 16ms). I'm actually surprised the monitor can deal with that without damage, so I've been leaving the monitor disconnected while debugging. The HSync period is correct (63.8us or so), and most of the addressing / character display logic (which is driven by earlier portions of the video timing chain) seems to be running correctly, it's just only getting a chance to draw one line of characters before the next frame starts. I'm not having much luck tracing down the fault; I have a schematic (http://www.zimmers.net/anonftp/pub/cbm/schematics/computers/pet/2001/320008…) but it's not making it easy to work out exactly how everything ties together. I can't find anything resembling a service manual for this model, but perhaps I haven't looked hard enough yet. The initial clock (output of E2 pin 6) is correct at 8Mhz; this is divided down to 2Mhz by the counter at C9 (pin 8, the divide by 4 output), which is passed to the 74LS107 at C7 and from here it gets murky and I don't quite see how things fit. I did replace C7 to no effect (ok, I jumped to conclusions...). The divided clock outputs (Q, pins 3/2) from this have a period of about 256us; the LS107 at B6 divides this down to the final period of 1.2ms which is used for the VSync signal. Has anyone here any experience with this hardware? Any tips? Thanks, Josh

Jack Livesley (co-host with Jim Butterfield) comes to the Personal Computer Museum Saturday

by sbolton＠bfree.on.ca

For those that remember "Bits & Bytes" and "The Academy on Computers" that aired on TVOntario in 1983, I have some great news! While sadly Jim Butterfield passed away in 2007, co-host of the Academy, Jack Livesley, is still around and will be coming to the Personal Computer Museum (http://www.pcmuseum.ca) in Brantford, Ontario, Canada to do a live Q&A Saturday November 15, 2014 at 1:00 PM EST. For those that are not aware, the Personal Computer Museum is a not-for-profit and the only interactive personal computer museum in Canada. It is also home to Canada's largest videogame collection (over 15,000 games and counting) and also home to the largest known collection of CED video discs too! The visit is of significance to me personally because Jack was one of the people that inspired me to choose computers as a career path. He will be accompanied by Karl Hildon, who was the editor of "Transactor" magazine which folks that loved Commodore computers will definitely remember as well. Directions and more information can be found on our website. For a glimpse at Jack and more details on the event, please see http://pcmuseum.ca/jacklivesley.asp Admission is free although donations of electronics and money are always appreciated!

drop in traffic yesterday

by jwest＠classiccmp.org

The drop in list traffic yesterday was my fault. The problem was on a system unrelated to the classiccmp server, but it only affected the classiccmp server. I believe it would have impacted just over a day of traffic. Problem resolved, and my apologies. Details for the tech oriented: Our hosting service has two front end mail processors (mx1/mx2) that do a lot of quick/basic checks before passing mail onto the backend mailbox servers. One of them had an issue and had to be restored from a backup that was a couple weeks old. We don't normally think anything of that in this particular case, because the config files on a front end mx basically never change so any backup is good. Much to my chagrin, I didn't realize that the backup for mx2 was taken BEFORE switching the mail stream for classiccmp.org >from the old ccmp server to the new one. Since both front end mail servers are equal preference, that means that about half the inbound mail for classiccmp.org was being directed to the old server which has pretty much been sliced up as things were migrated to the new server. Last night I changed mx2 to deliver to the correct/new classiccmp server (mx1 was already doing so), and that fixed the problem. Newbie mistake, my apologies. Best, J

Wanted: Altair / S-100 serial comms board w/ documentation

by drlegendre＠gmail.com

Just taking a stab.. I've run out of options trying to locate docs for the lone S-100 serial board in my stash, so I think it's time to look for a new unit. I don't own a logic analyzer, nor have I sufficient experience to figure out how to put my current board to use in the absence of docs.. so it goes. Does anyone have an S-100 (for Altair, in specific) RS-232 / serial communications board with available documentation? Just looking for something that can be made to work with a common serial terminal (emulated) so I can play around with BASIC and so forth. Plan is to use a basic 486 / Pentium laptop running Linux + Minicom or similar to emulate a VT-whatever on the Altair's comms port. (As an aside.. a bit of a mea culpa - I +did+ once own a genuine ITT (I think it was ITT) tele-tank with a paper tape machine. Picked it up for $15 at a local electronics surplus - AxMan - back in the early 1980s. It didn't work right.. or at least I had no idea what to do with it. When powered-up, it would begin to print blank lines over & over, line after line.. just sat there, running away like crazy doing nothing. I had not the slightest idea how to deal with it, so I removed the works >from the top of the base, and THREW IT OUT OF MY SECOND-FLOOR BEDROOM WINDOW. It was so heavy, I didn't want to have to carry it back down. The base served as an excellent printer stand for several years, and the not-so-obvious access panel did well to conceal various contraband during the same period.)

DECwriter Correspondent (LA12) mechanical issue...

by derschjo＠gmail.com

Hi all -- Got myself a nice looking DECwriter Correspondent (AKA the LA12). It's having a bit of trouble moving the carriage assembly and I can't find a service manual for this thing. (It's similar in some respects to the DECwriter IV, but the mechanical parts appear to be fairly different.) The carriage assembly (print head, ribbon) is carried from one end of the platen to the other via a cable attached to a servo motor on one end and a pulley on the other; in the middle of this cable is a small metal ball -- this ball is (as far as I can tell) meant to sit in a small "cup" on the underside of the carriage and when the cable moves, the ball pulls the carriage along. I'm assuming this was done this way since the Correspondent is meant to be portable, and allowing the carriage to break free of the pulley mechanism would probably reduce damage in the case of a sudden shock (like getting dropped.) So far so good -- unfortunately the vast majority of the time, the ball leaves the carriage behind (especially on carriage return) and I can't quite figure out what's out of tolerance -- the carriage appears to move smoothly, nothing is bent out of shape or broken as far as I can tell, and there's plenty of tension in the cable. There's also not much to adjust here so I'm kind of puzzled. I've put up a few pictures (and a short video demonstrating the problem) with the print head/ribbon removed here: http://yahozna.dyndns.org/scratch/la12 Anyone ever worked on one of these before? Any ideas? Thanks as always, Josh

assistance sought with mailman

by jwest＠classiccmp.org

Greetings folks. The additional drive was added to ccmp server last night. No problems encountered other than for some oddball reason xenserver added it as drive 4 instead of drive 3. It thinks drive 3 slot is in use but it's not. I can live with ada3p1 ;) I've got my hands full with some work on bitsavers as well as ongoing client workload, and some rough edges still remain on the mailman "two views of the same list but joined at the hip" thing. That needs to be addressed quickly before the current/new archives get incoherent but I'm short on available time. So, is there anyone that is *very* well versed in mailman "under the hood" that can do a one-time assist with the following: 1) Get the "two views of the same list but joined at the hip" working the way it previously was. I have some details/recollections on this, but not complete "do this" instructions. 2) There has been an ongoing issue for years with the "forgot password" emails and/or the new subscriber email verification not working right. 3) Please for the love of god figure out why every single post to the list gets me a "bounce rejection" notice to my mailbox and stop it. 4) Integrate multiple fragments (I have several, if that's not complete other listmembers have mentioned they can supply any missing fragments) of the list archives into one archive that is complete. FYI - when rebuilding the server a couple weeks ago, I switched from sendmail to postfix, so a passing familiarity with postfix would be helpful as well in your endeavors above. The OS is FreeBSD r10 p11. If anyone is versed in the above and has a bit of time to spearhead the above tasks, please email me off-list. Also - once the archives are cleaned up, two other folks have volunteered to get archive searches to be "much improved". Thanks!! J

Kearney & Trecker Core memory, may be PDP8

by jnc＠mercury.lcs.mit.edu

> From: Paul Anderson > The first board is definitely a DEC core board. If it will help anyone > I can pull a MM8-A and MM11-D and compare them to the pic to see which. That would be really useful. If I had to bet, I'd go with the 8: DEC SPC/MUD memory boards often have CA1 jumpered to CB1 (NPG), and I don't see that here. And the way CC1 is ganged to CF1 to CT1 is very odd - CC1 is Parity A in an SPC/MUD slot. (Yes, it could be for a specially wired system unit - but those don't usually use hex cards.) And then there are a number of different kinds of component (e.g. the transistors in the cans, TO-18 I think?) which seem to be in multiples of 12. Too bad there's no picture of the edge of the handles to give us an M-number! Noel

IBM 5151 (MDA display) - common faults / gotchas?

by jules.richardson99＠gmail.com

So, my local bookstore guy has an IBM 5151 monitor for sale, which is surprising because: a) I haven't seen *any* vintage IBM PC kit locally in the last 8 years, b) I picked up a 5160 with an MDA display adapter but non-IBM monitor from John over in Duluth a few weeks ago, and I was thinking what a shame it was that it didn't have the original IBM screen. So, it's almost like it's meant to be, or something... Of course working condition is unknown, so before I commit to it, are there any common showstoppers with these displays (failed CRT, yoke windings, LOPT etc.) - or are whatever faults that may be typical with them all in components that are still available? (I'm kicking myself a bit because he said I was welcome to bring it home over the weekend to try it out and then bring it back if I decided I didn't want it - I just couldn't remember at the time if the 5151 was the MDA display or something else, but with hindsight I probably should have just taken it regardless!) cheers Jules

Whitesmith C install

by quapla＠xs4all.nl

I'm trying to install the Whitesmiths C compiler under RSX11M using FLX (using the Whiteshmiths c compiler distribution tape V2.25 from bitsavers). Alas, 'FLX' says the tape has zero files and directories, while a dump under Linux shows definitely some contents. I tried both the simh & tpc format, no luck here yet. Am I missing something? The command I used is 'flx /rs=ms0:[*,*]/do' Thanks, Ed -- Dit is een HTML vrije email / This is an HTML free email. Zeg NEE tegen de 'slimme' meter.

ADDS 4000/260 keyboard connector

by jules.richardson99＠gmail.com

Longest of long shots, but does anyone happen to know the keyboard connector pinout on an ADDS 4000/260 terminal? I have such a terminal here, and it has a 6-pin RJxx-type socket, but the keyboard which came with it would appear to be for something else, and has a 4-pin RJxx plug (I'm not sure of the actual RJ designations, but they're physically different, albeit close - the keyboard one fits in the terminal's 6-way socket, but is too loose to make contact on its 4 pins) However, the manual for the terminal mentions supporting a PC keyboard, so it's possible that a standard PS/2 keyboard with the PS/2 connector lopped off and replaced with a suitable RJxx connector would work - i.e. the clocking method and scancodes are identical - if I knew the pinout (it's also possible that the same is true of the keyboard that came with it - the physical layout's identical to a PC, but with the addition of a 'select' key) cheers Jules

Tektronix Microlab I?

by nw＠retroComputingTasmania.com

I found this item on eBay: a Tektronix Microlab I with 8086 personality module, but can't seem to find much about what capabilities it provided. It doesn't seem to be in the same league as the Fluke 9000 series (9010A etc) so what could it do? Was it simply a way of testing out different microprocessors (like a SBC with plugin CPUs)? http://www.ebay.com.au/itm/380885770121

PDP-11/23 Debugging

by jnc＠mercury.lcs.mit.edu

> From: Ben Sinclair > Then, in between trying a few things (but without touching the > hardware), the machine seemed to get very flaky. > ... > I tried removing the RLV11 boards, returning the machine to it's former > state, but I have the same issue. This is a total _guess_, but... I've recently been working with some 11/23's I just bought, and I too had similar flakies appear mysteriously with one of them. I'm not sure exactly which of the below finally cured them, but you can try the following things (one of which finally did it for me - after sitting for a long time, the connections can possibly be slightly flaky): - re-seat all the cards in the backplane - re-seat the chips on the CPU card (take them out _very_ carefully, slowly levering from all 4 corners - they are brittle, and you can fracture the carrier if you get too aggressive) - re-seat all the jumpers on the CPU card I also discovered and repaired at least two cold-solder joints (one was one of the pins for W1, the master clock control - the pin was actually loose when I wiggled it). Cold solder joints are pretty insidious - they can work fine for a while, and then start to give problems. Do you have more than one memory card that you can swap in/around? That might be it, too.

Netronics Phoneme generator info

by jules.richardson99＠gmail.com

Random find in my local book store's pile of scrap electronics heading for recycling - a Netronics Phoneme speech synthesizer. IC dates all around mid-1982. I just have the board, no case or anything, but it appears to be reasonably self-contained: there's a connector for PSU, a phono which I'm guessing is speaker out, pots for volume and pitch, and a DB-25 connector. The DB-25 only has pins 1,2,3,7 & 20 in the socket, so I'm assuming it's RS-232. Does anyone know anything about these? Assuming it still works (it looks like it just expects 6-9VAC or thereabouts on the PSU connector), is the control protocol documented anywhere? DIP switch settings? (there are 8 on the board, labelled BSY, 3, 2, /C, /C, B, P, C) Looking at the PCB traces, it appears to allow data input by either pin 2 or 3 (dictated by the '2' and '3' DIP switch settings), but there's no data sent out down the serial line, so communication is write-only. I suppose it's possible that I hook up a terminal and (assuming that I have the line parameters right) start typing English, but it's probably not that simple ;) cheers Jules

Years ago I ordered a lot of equipment from "The TRS-80 Recycler." It took over a year and dozens of really lame excuses before I received it all.

If I was in that situation I'd probably just stop accepting new orders (i.e. cash) but accept backorders. Tell the buyer honestly how long it might take and charge the money only the day it ships.

VAX 11/730 Documentation

by shadoooo＠gmail.com

Hello, > I haven't booted my machine up yet, because it hasn't been able to read any of its console tapes. I have too a lot of tapes, complete and uncomplete sets of software installation tapes, plus two/three console versions and some with unknown content. The problem is, many of them suffer from sticky rubber on tape (if you try to move the rubber leader, it will create blank spots on tape, removing the magnetic oxide substrate). Other have a broken band. I read somewhere around, it is possible to detach the rubber band using hot air, and replace it with some sort of PVC strings. I would need a lot of time to try something... but the bigger problem is not this... I don't have a TU58 to be used on the desk to try to read the tapes, and even better to assembl?e a new firmware allowing to format blank tapes. I'm trying to buy some piece of hardware since a lot of time... no luck so far. If anybody has a TU58, or parts, please let me know. Andrea

list back up

by jwest＠classiccmp.org

The classiccmp server and it's backups were on a temporary san that hit a bug and rebooted itself. Needless to say, dropping iscsi to a hypervisor is not a good thing. The classiccmp vm thus rebooted itself, ran fsck, and (as best as I can tell) the only thing corrupted was the cctalk and cctech config.pck files (which contain the list settings and membership). The only backup had the same corruption on it, because it ran the backup before I noticed the problem. Anyways. Knowing the recovery wouldn't be quick/easy anyways, I took the opportunity to just build a new classiccmp server VM from scratch. The latest OS, patches, dependencies, libraries, and ports. This new VM is on the new production san so there's a pretty fair amount of additional disk space thrown at classiccmp (and thus bitsavers). It's always amazing when I revisit this just how many packages/services are on that machine that a reload from scratch requires. It's been a busy few days/nights. Things you should know: 1> The membership list for each list was recovered thanks to the hard work of DBoone. He processed the last few days of maillogs to get the subscriber lists back. THANK YOU D. 2> Given how we had to do #1, it is possible that a few folks that had subscriptions weren't automatically re-subscribed (someone who set their membership on 'no email' could be one example). Those folks will notice and just resubscribe. 3> Given the very bizarre way we had the cctalk and cctech lists "joined at the hip", I do not recall the magic we did to get that working properly. I am aware that posts from one probably aren't being redirected to the other like it used to (if at all). I'm working on refiguring that out, and any suggestions (offlist) would be most appreciated. 4> Given that I had to recreate the lists configurations from scratch, I'm pretty certain that I have some settings different than used to be. If you find anything different that matters, let me know. 5> The "new" classiccmp server is currently hosting the mailing lists, the classiccmp.org website, plus all websites that are underneath classiccmp.org (ex. www.classiccmp.org/hp , www.classiccmp.org/cpmarchives , etc.). Thus, you may notice a different ip address and hostname on the server. The new name/IP will stick till any future rebuilds. 6> The "old" classiccmp server is still up, and is hosting all the websites that have their own domain name. Time permitting, I'll be migrating those one at a time to the new server. During that time period - however long it takes - ftp and rsyncd will not be available to prevent loosing changes when cutover occurs. 7> I do not recall who all the folks were that were helping review/gate posts between cctalk/cctech. If you were one of those folks, please let me know asap off-list so I can get you re-added. 8> For people who have websites hosted on the classiccmp server, be aware the new server is running mysql56, php56, and apache24 (with mod_itk). Before your website is moved, let me know if you're aware of any breakage that using those new versions may cause. I'd also prefer to transform any myisam databases to innodb unless you're aware of an issue that may cause. 9> Please do not post to the list or email me directly about "hey, the archives are gone!". They have been preserved, and time permitting they will get imported back into the "new" mailing list (along with the missing 199x bits that were recently mentioned). Rumor has it that someone has volunteered to improve the archive search mechanism in the not too distant future. 10> Many people have asked me over the past year or so to host their classiccmp-related website, and I pushed them off due to the lack of disk space. That is no longer an issue so if you're one of the people wanting that (and still do), now is the time to get back in touch with me. As always, we'll host any classiccmp-related website free of charge. 11> Within the next 30 days (at most) we'll be adding the classiccmp server to our CDN service. The advantage: I would expect to be able to remove any/all bandwidth limits previously in place and folks will be able to download files from the bitsavers master very quickly and your classiccmp-hosted websites will be a lot more snappy. The downside is, you'll have to either be ok with it taking a while for new/changed content on your site to be visible world-wide, or you'll need to take a look at the api (or via a CDN website login) to invalidate the cache when you change something. In most cases, this can be easily automated. 12> During the mailing list outage, all websites and bitsavers were still up. It was just the mailing lists that were affected. I'm sure there's more that I've forgotten. But.. Enjoy! Best, J

Recovery CDs for Thinkpad 2647-44U (T-20)?

by jrr＠flippers.com

Anyone have one of these sets (2 or 4 CDs) for the old IBM Thinkpad? I have a nice old timer here that I want to use for some older applications (ancient EPROM programmer) and this would work nicely if I could find the drivers. At the moment I can only find invalid torrents or what certainly looks like malware 'drivers' to download. IBM off-loaded everything to Lenovo and there is nothing on their site that I could find for these legacy machines. Archive.org has the support site archived, but not the download files... eg: https://web.archive.org/web/20060713020434/http://www-307.ibm.com/pc/suppor… Seems a shame to recycle a perfectly good computer just because one can't get it running on all cylinders!

Sun Cardcage Manual

by silent700＠gmail.com

I've been back at scanning the big pile of Sun binders lately and I'm down to the last box (that I can still find.) I've uploaded a few over the last 24 hrs but one may be worth calling attention to for early Sun fans, doc #813-2004-14, "Cardcage Slot Assignments and Backplane Configuration Procedures." I've seen a number of FAQ and help pages with charts pulled from various versions of this doc but not the whole thing. It covers various models of the Sun-2 through Sun-4 range. You can find it and the others here: http://chiclassiccomp.org/docs/index.php?dir=%2Fcomputing/Sun -j

Vintage UNIX computers/servers for SALE-auction

by janprunk＠gmail.com

Hello ! Vintage workstations and servers for sale/auction in Slovenia, Europe. Below is the list of hardware, if you are interested, please read the details regarding the sale terms at the end of the list. For anything else you wish to know, please direct all questions regarding equipment to E-mail janprunk-at-gmail.com and not to the mailing list. 3 x HP 712 1 x Switch Hubstack JEHI-24 1 x Power Macintosh 7500/100 2 x SUN Sparcstation 4 1 x HP 9000 PC-308 (XT) 1 x Digital DEC 3000 1 x HP Terminal (monitor) 700/96 1 x Digital DEC 2000 1 x HP 9000 E35 STATUS OF THE EQUIPMENT : Equipment is being sold AS IS, meaning there is no facility to test it ! Computers should be in a working condition, some were even used by me personally, but consider them being sold as a DEFECT, due to its age, limited skills and lack of my time to exclude warranty terms. I am able and willing to provide the photos of the exterior, but please don't ask me to open up the machines to photograph the interior or components, boot up the OS, test the condition etc. I can provide exact model and serial number if that will be helpfull to you. Some computers come with the original hard drive inside and some don't. AUCTION: You are welcome to bid prices for this equipment. To limit the sale to serious bidders, I will only consider bids above 100 EUR per computer, if there are more bids for the same computer I will consider the highest offer. I haven't placed the equipment on EBAY at this time, because that would make me obligated to ship the computers even with a 1 EUR bidding win price and that would just mean too much work and no pay for me. PAYMENT: I am able to accept bank wire as a preferred method, cash or cheque, cryptocurrencies, such as Bitcoin but I am unhappy to accept Paypal due to its refundment policy which always sticks with the buyer. SHIPPING: I would prefer if you can do local pickup, however that might not be possible for people who don't live near Slovenia. I am willing to ship the equipment by mail, but be advised that Slovenia foreign parcel shipping is very expenssive so it wouldn't cost less than 80 EUR to ship the computer across Europe, due to its weight and dimensions. Shipping outside Europe would probably even double the amount, but if you are a serious collector I will also consider that option if you are willing to pay for shipping. I might have the accessories for computers - keyboards, cabling ... but consider the workstations being sold without that, as shipping the workstation + keyboard can be a problem, due to different dimensions and it would need to be packaged into two separate packages, therefore doubling the shipping costs aswell. ADDITIONALS: Keep in mind that bids below 100 EUR would just mean too much work for me to organise the shipment so I would rather not deal with it. I hope that the computers can find a new home with some other collector. For anything else you wish to know, please direct all questions regarding equipment to E-mail janprunk-at-gmail.com and not to the mailing list. I wish you all a happy bidding ! Kind regards, Jan Prunk

Vince Briel computers

by gkaufman＠the-planet.org

Has anyone been able to reach Vince Briel recently? I hope he's ok, as I've enjoyed his pocket-term and micro-kim kits. I ordered a Superboard III kit on August 25th. I was hoping to use it as a gift in early October! On 9/18 I heard back with "Hey Gary,I have a OSI 600 and I can say the Superboard III is really close to the exact same thing (little better video quality). I'll look for your order and see if I can't get it out shortly" And on October 13th "Hi Gary. Sorry ive been moving this week. Should be done in a day or two. My main pc went down but i should have it fixed this week. Still only have phone for internet." Nothing since, and no additional information on his forum or website.

PDP-11/23 Debugging

by jnc＠mercury.lcs.mit.edu

> From: Noel Chiappa > I also discovered and repaired at least two cold-solder joints (one was > one of the pins for W1, the master clock control - the pin was actually > loose when I wiggled it). So it turns out that loose wire-wrap pins seem to be a systemic problem on 11/23's. I just discovered _3_ more on one single 11/23 board - two of them the pins for the master clock! I put my finger-tip on them and wiggled, and they were loose. I'm not sure why it's the wire-wrap pins especially - maybe their physical size meant that they have larger thermal inertia, and so need a longer heat than the manufacturing process gave them, to bring them up to temp to prevent a cold solder joint? Anyway, if one has a flaky 11/23, that's definitely something to check. Noel

PDP-11/23 Debugging

by bensinc＠gmail.com

I've been working on getting a PDP-11/23 running for a while now, with various amounts of success! I had it in a state where I could boot XXDP from a virtual TU-58 and everything seemed to work pretty well. I then got ambitious and got an RL02 and an RLV11 (M8013+M8014), and last night I tried to get the RLV11 to pass the unconnected diagnostics that just test the controller. I tinkered with it for a while, but never got it to work. Then, in between trying a few things (but without touching the hardware), the machine seemed to get very flaky. Right now I can still boot an XXDP tape image, but as soon as I try to do anything it dumps me back to ODT: NOT ENOUGH MEMORY TO BOOT XXDP-XM BOOTING UP XXDP-SM SMALL MONITOR XXDP-SM SMALL MONITOR - XXDP V2.6 REVISION: E0 BOOTED FROM DD0 28KW OF MEMORY NON-UNIBUS SYSTEM RESTART ADDRESS: 152010 TYPE "H" FOR HELP . 150674 @ I tried removing the RLV11 boards, returning the machine to it's former state, but I have the same issue. I'm pretty new to all of this and always have trouble figuring out what the next debugging step should be. My machine is a PDP-11/23 with a H9273 backplane. I have, in this order >from the top: M8186, M8043, M8044DF, and an M8012 at the bottom. Any help would be appreciated! Thanks! -- Ben Sinclair ben at bensinclair.com

list issues & status

by jwest＠classiccmp.org

As I suspected and alluded to before, there are issues with the list(s) that were pretty much expected (loss of previous settings of digest mode, as well as cross posting resulting in duplicates, and in some cases posts showing up as attachments). Yes, I am aware of these issues. I just received a post from a listmember about their "patience wearing thin". To that list member, I suggest you unsubscribe completely from both lists permanently. Obviously we're not the best choice for them. My patience is not wearing thin just yet. If yours is. please leave. Given that the list(s) are at least semi-functional, albeit with some issues, I switched gears and have been working to get the websites and other services migrated from the old server to the new server, and am almost complete with that. Should have the last website migrated by Friday as well as a few changes that are needed on the main bitsavers repository. After that, I'll start digging into the remaining issues with list functionality and then finally we'll start dealing with getting the archives imported (along with bits that have been missing for a while). Thanks so much for all your patience folks, we'll get there. Best, J

FW: TNMoC News - The winners of the 2014 Tony Sale Award for computer conservation

by dave.g4ugm＠gmail.com

I hope folks don't mind me forwarding this, but some interesting, if probably well know links. Dave G4UGM From: noreply at salesforce.com [mailto:noreply at salesforce.com] On Behalf Of Mike Kelly Sent: 07 November 2014 12:26 To: dave.g4ugm at gmail.com Subject: TNMoC News - The winners of the 2014 Tony Sale Award for computer conservation NEWS RELEASE from the Computer Conservation Society The winners of the 2014 Tony Sale Award for computer conservation are . a virtual 1930's mechanical computer and a restored industry-changing computer. 7 November 2014 The 2014 Tony Sale Award for computer conservation has been jointly awarded to two outstanding and contrasting entries representing computing in the 1930s and the late 1950s. The winners are the IBM 1401 Demo Lab, a restoration of one of the most significant machines in computer history by the Computer History Museum in California, and Z1 Architecture and Algorithms, a virtual reconstruction of the 1930's Konrad Zuse mechanical computer, by the Free University of Berlin. Run by the Computer Conservation Society and sponsored by Google UK, this is the second Tony Sale Award for computer conservation. The first was won in 2012 by Dr David Link for LoveLetters, a computer art installation that continues to tour the world. In announcing the 2014 winners, Martin Campbell-Kelly, computer historian and head of the judging panel, said: "The eight excellent entries for the 2014 Tony Sale Award from four different countries clearly demonstrates how computer conservation is flourishing more than 20 years after Tony Sale embarked on his pioneering and awe-inspiring reconstruction of a Colossus Mk II, a world-famous exhibit at The National Museum of Computing on Bletchley Park." The IBM 1401 Demo Lab is a classic reconstruction of a 50-year old commercial computer. It marked the transition of IBM as a supplier of accounting machines to it becoming the dominant supplier of the mainframe era. Announced in 1959, the IBM 1401's success took everyone by surprise. The company had expected to sell or lease about 1,000, but went on to deliver 15,000 and by the mid-1960s they amounted to half of the computers in the world. Its high-speed chain printer was a key to its success -- punched card machines were eagerly traded in for the IBM 1401 and business computing took a huge stride forward. In a project involving 20 volunteers over ten years, two 1401s have been restored at the Computer History Museum in Mountain View, California. The computers and the ancillary equipment including the famous 1403 chain printer are on permanent display and the working system is demonstrated twice a week. See <http://www.computerhistory.org/atchm/restoring-the-ibm-1401/> http://www.computerhistory.org/atchm/restoring-the-ibm-1401/ for more information about the project. The judging panel said: "The IBM Demo Lab is a flawless restoration of a machine that signalled a turning point in the computer industry and the use of computers in business." Z1 Architecture and Algorithms, the other joint-winner, is a virtual reconstruction of one of the world's earliest computers, the Z1. Originally built in 1936-38, the Z1 was destroyed in a bombing raid in 1943. In the 1980s and then in his 70s, Konrad Zuse embarked on a reconstruction of the Z1 which is now a remarkable but static exhibit at the Technology Museum in Berlin. However, with 30,000 parts the reconstruction of the mechanical computer was unlikely to be robust or reliable enough for regular operation, so a team led by Professor Raul Rojas began a virtual reconstruction with a technical description. Through the meticulous research of Professor Rojas, a team of his students was able to construct a 3D visual simulation of the arithmetic unit for deployment on the web. In addition, hundreds of high resolution photos of the Z1 enable web users to explore the machine from any angle at very high resolution. See <http://zuse-z1.zib.de/> http://zuse-z1.zib.de/ for the virtual reconstruction. The judging panel said "Z1 Architecture and Algorithms is a remarkable vision of how such complex artefacts might be delivered to a worldwide audience. It is a project that will undoubtedly give museum curators pause for thought." Rachel Burnett, Chair of the CCS, said "The late Tony Sale would have been delighted with the entries that we have had in the year of the silver jubilee of our Society that he co-founded with Doron Swade. "The computer conservation movement is dynamic and growing apace. Through the Tony Sale Award, we salute the computing pioneers of the past and the dedication of those today who breathe vibrant life into our incredible computing heritage." Notes to Editors 1 The Computer Conservation Society Established in 1989, the Computer Conservation Society (CCS) started as a joint venture between BCS, The Chartered Institute for IT, the Science Museum and later the Museum of Science and Industry in Manchester. In recent years The National Museum of Computing has become a key partner. 2 The CCS Judging panel Martin Campbell-Kelly, computer historian, was joined in the 2014 panel of judges by Chris Burton, engineer and computer conservationist , Nigel Sale, computer scientist and son of Tony Sale, and Doron Swade MBE, museum curator and author. 3 Links to other nominated entries for the 2014 Tony Sale Award The Analogue Computing Museum collection in Schwalbach, Germany. <http://www.analogmuseum.org> www.analogmuseum.org The Jim Austin Computer Collection in York, England. <http://www.computermuseum.org.uk> www.computermuseum.org.uk The restoration of 1970s DEC PDP computers at The Rhode Island Computer Museum (RICM), Rhode Island, USA. <http://www.ricomputermuseum.org> www.ricomputermuseum.org The PRS 4, a restoration of a 1973 Polish micro-computer at the Muzem Historii Komputerow i Informatyki (MHKI) in Katowice, Poland. <http://www.muzeumkomputerow.edu.pl> www.muzeumkomputerow.edu.pl The Technikum29 Computer History Museum collection in Frankfurt am Main, Germany. <http://www.technikum29.de> www.technikum29.de The WITCH-E project, a trans-Atlantic educational project, by David Anders. <http://www.elinux.org/WITCH> www.elinux.org/WITCH 4 About Tony Sale Tony Sale (1931-2011), in whose honour the computer conservation award has been established, is perhaps best known for leading the team that rebuilt Colossus, the world's first electronic computer.

HP9810A alive again!

by mattislind＠gmail.com

After replacing a lot of dead National Semiconductor TTL ICs this nice little machine from 1972-1973 is running again. It works perfectly to do calculations and also to create programs. I also managed to both store and restore a program written onto a home made magnetic card. Home made since I wasn't able to find any. There are a few issues left: The belt in the card reader is slipping a bit so a replacement would probably be needed to get it working 100%. One segment in the display is dead. Anyway: Here is the writeup of the restoration: http://www.datormuseum.se/computers/hewlett-packard/hp9810a and here is a video-clip: https://www.youtube.com/watch?v=C9rBoWvze48 Enjoy! /Mattis

OT: reply-to munging

by jwest＠classiccmp.org

Oh hell. I sure didn't mean to open up that can of worms (the every year or so debate on if replies should be to the list or to the poster). But since it HAS been brought up.... Background for short-timers: There is a recurring debate every year or so as to the reply-to headers setting on the list. The way it works now, when the list sends out list traffic/posts to each of you, it "munges" the reply-to header so that when you hit "reply" to a list post, the reply goes to the list. If you want to just reply to the poster directly (off-list), you have to go through gyrations like hitting forward and typing in the senders email address. Taking off my list owner hat... the following is my own personal opinion on the topic which shall not be dictated upon the rest: I think that's insane, not to mention that I suspect it violates some RFC's and breaks the good intentions/functionality of most MUA's. But regardless.... if the list was set the other (the normal) way... when you get a post you hit reply to reply directly (and only) to the original poster and if you want it to go to the entire list - you hit "reply all". I mean, come on - that's why mail clients HAVE a reply vs. "reply all" button. The only argument I've heard that is vaguely cogent for the current method, is that people will often hit reply with a golden nugget of information and the rest of the list will miss out on that. The argument on the other side of the fence is that having it set the way it currently is causes people to very often post things to the list that were meant to be private. I am of the opinion that the reply-to should be set to the poster, not the list, and let people use their MUA the way it was intended. That being said, I'll defer to whatever the majority of folks wish. On the other hand, this list is mainly frequented by Grumpy Old Men aka Curmudgeons - of which I am most certainly one - and changing this well-entrenched behavior is likely to start a religious war which I want no part of :) <troll>So how bout that 10-year rule?</troll> ;) J

VCF East 10 -- aka "VCFeX" is almost six months away (April 17-19, at our museum in Wall, New Jersey). But the planning is in top gear! I'm very happy to announce that our keynote speakers will be Dr. Dr. Ted Nelson (Saturday -- he has two doctoral degrees) and Bob Frankston (Sunday). The event web site is just beginning to get populated, so please pardon the lack of details for now: vintage.org/2015/east/ .... we're also social at facebook.com/vcfeast and we just joined Twitter.com a few minutes ago @vcfeast. New for 2015: more technical classes on Friday; longer exhibit hall hours Saturday and Sunday.

Multiple copies of messages

by tpresence＠hotmail.com

It appears I'm receiving multiple copies of many messages, but not for every post. Any way to remediate this without an unsubscribe? Kevin

Moderation

by robert.jarratt＠ntlworld.com

Slightly confused as I posted something this morning to cctalk and I got back a message saying my post was awaiting moderation for cctech. I can sort of understand in that I didn't post to cctech, but neither did my post appear on cctalk. Something may not be quite right... Hope this one makes it :-) Regards Rob

Mailing list issues (was: Whitesmith C install)

by jnc＠mercury.lcs.mit.edu

> I used to get this list in digest format which was nice. It seems like > this setting has been reset for everyone. Jay made it quite clear that they had totally lost the mailing list configuration, and that they had to re-create the list of subscribers by looking through out-going mailing logs, which would only give them addresses (at least, from simple processing). In other words, all the configuration info had been lost, and people would have to reset things. Now, can we get back to technolgy? Noel

Failed H7864 PSU

by robert.jarratt＠ntlworld.com

A little while ago I posted about a H7864 PSU (from an rtVAX 1000) that had failed on me with a loud pop and no apparent physical damage. I discovered which component has failed and it is a large transistor, Q301, but I have yet to find out why it failed. To help, I have been working out the schematic for the area of the PSU that failed, which is labelled Primary Control Module, and situated after the rectifier and before a large transformer that appears to isolate the following stages of the PSU. The aim is of course to use the schematic to attempt to work out the cause of the failure and repair that too before it blows up the replacement transistor or damages some other part(s). The schematic is here: http://1drv.ms/1yBzYTN (png) or here: http://1drv.ms/1xFXUnR (Eagle schematic). I may not have drawn it logically, and may have some bits wrong, as it is quite difficult to derive the schematic and it is easy to make mistakes. I don?t know how to identify zener diodes, so all diodes are drawn as ordinary ones. I was also unable to draw the transformers correctly as I don't know their spec and pinout. I have found some of the capacitors in the circuit to have a high-ish ESR. C407 in particular has a high ESR, C404 has a high-ish ESR, and C303 needs re-forming but I don?t yet have equipment that can produce a high enough DC voltage (should be able to do this in a few days time). My plan is to replace all three of these. Whether these would cause Q301 to pop I don?t know, what do people think? There are also some heat marks around D408 and possibly R415 (both seem to test OK). Are there any other bits of the circuit that I should check that might cause Q301 to pop? Any advice really appreciated! Thanks Rob

Anyone still playing with HP 1000/2000 minis?

Penfield High, NY where I attended, had a 19" cabinet with an HP-2114B (B?) and a ASR-33 console. There was also an HP-2761A Optical Mark reader, and I'm not sure the printer. At the time I used it, there were 4 "consoles" running and time slicing was done on each line of basic. The card reader was one input, and the printer was the output. The ASR-33 was the only interactive terminal the previous year, but new this year were two crt serial terminals. They were not the HP branded terminals. There was a paper tape punch and a reader. The punch was disconnected and sitting over on a shelf. As I recall there was a dual 8" floppy drive inside the cabinet. There was no login on the terminals. Files starting with an exclamation point where invisible to directory listings. I've not found a time-shared basic that matched this type of configuration. Dick Stover (now deceased) was the systems operator for a number of different schools in upstate New York that ran similar setups. Is the HP24160A you mention a software system? or the bundling of specific hardware? both? Is the BASIC multi-user? There was a grading program in the system that, as I recall, was triggered by a CALL -151 command in basic. Thus a teacher would include the magic card that triggered the app, then include a card marked with the correct answers, then as many cards to be graded as they liked. I don't recall how this was ended. Might have been a special end card. The printer would then print a grade report for each card. All other processing on the other "consoles" would halt until the grading was complete. Then the BASIC time slicing would resume where it left off. I have some partial source listings from back then of the D&D program we were working on. It used a number of "chained" programs to do: map generation, map navigation, battle encounters, inventory management, etc. We had functions to pack and unpack date into floats as I don't recall the BASIC supporting direct integers. I'd be very interested in any source that might be this version of BASIC. I've looked at the Montana State University basic, but this does not look like what I recall. Sources for some of this up on my site: http://rikers.org/hp2100/ check out the "msu" directory. I have: HP-2116A (non-functional, yes, that's an A, not a B or a C) HP-2100A (not powered up) HP-2108A (functional) HP-2112A (functional) HP-7900 (broken chassis) HP-7901 * 2 (never powered up) HP-2748B Paper Tape reader HP-2761A Optical Mark Reader Geek porn: http://rikers.org/gallery/hardware I'd trade it all for a functional HP-2114B :) I loved the touch sensitive switched on that model. I'm in SLC Utah if anyone wants to see any of this.

HP systems AS400

by mstaunton＠roadrunner.com

I was referred by Jon Johnston at http://www.hpmuseum.net/. he had mentioned this group would be able to assist in sourcing complete AS400 servers with CRTs to some collectors that maybe interested. I would like a museum to have them for their collection or a collector that would use them as functional servers.

X11R3 source, patches for IBM RT?

by bear＠typewritten.org

I'm working on a project relating to the IBM RT, where the original vendor distribution is not available (or hasn't been un-lost yet, and the "supported" release is X11R2 anyway). Do any of the much esteemed list members have in their posession a distribution of the X11R3 source? Preferrably one contemporary to the period when it would have actually been in use? I have the source generously provided by X.org, but it seems a bit poorly curated and I'm not sure of its actual provenance. There are more than a few files which have much newer modification times than I would expect, and very few of the IBM-provided source patches for bug fixes (which I do have) will apply. In some cases the code is not even remotely similar. So... since I've run into trouble with the X server built from this source, I'm looking for a second opinion in the form of an X11R3 source distribution that has a known provenance. Apparently there were also >700k of patches for X11R3 that MIT provided on the RT, which are mentioned in an IBM TSB. Of course now those published sources are no longer active, and I have no way of knowing whether they're already applied to the X11R3 source at X.org. From the IBM TSB: --begin quote-- "Note that X11 release 3 distribution and the improvements made since the release of X11r3 for the IBM RT are NOT AVAILABLE from either the host ibmsupt, IBM's Advanced Workstations Division (Palo Alto), or the ACSC. These are only availble directly from MIT, or other locations on the Internet as described below. The latest IBM/4.3 code (patches, etc.) is available via anonymous ftp >from expo.lcs.mit.edu, the file name is: contrib/ibm-rt.r3-fixes.tar.Z The size of this file it is about 730k. The Scheifler et al announcement follows. --end quote-- If anybody knows of an archive where a copy of those patches might be found, that would be tremendous. So far I've come up empty-handed. Everything at MIT I've found is X11R4 or newer. Everybody seems to have been in a big rush to forget the older versions (possibly I could not blame them for that). Anyone? X11R3 source and/or RT patches? Thanks! ok bear. -- until further notice

IBM 7868-047 Modems

by cctalk＠fahimi.net

Ahhh nice to have the lust back! About a year ago I "rescued" a whole rack of these modems off the side of the street. Unfortunately, they do not come with ANY documentation and my Google fu has so far determined that they are most likely for leased lines only. Does anyone have any info or familiarity with this modem? I know some other IBM LL modems could work over PTSN but had to be set in the right mode. Can this be done for these modems? Also does anyone know if these modems will accept standard Hayes AT commands? Or just the IBM command set? Which brings me to my next question what is the IBM command set? Any documentation or guidance is very much appreciated. I would love to get these guys up and running! -Ali

Apple IIC w LCD

FCO for KDA50-Q?

by jnc＠mercury.lcs.mit.edu

> From: Nigel Williams > I have some Emulex SD590 drives which require a controller like the DEC > KDA50-Q (M7164+M7165) or KDA50-QA.

(I don't know, merely raising the question.) > the KDA50-Q has a rather bad (show-stopper) bug that was fixed in later > revisions, detailed here: I'm not sure that's a fatal issue; maybe it just causes the controller to have to re-read that last block?

What should I be > looking for on the board that would indicate it has had the FCO > applied? Generally DEC indicates the ECO level by a stamp or something similar on the module handle(s) on the back side. I looked at a couple of M7164/M7165 board pairs which I have (which seem to date, from the date codes on the ICs, to the '87-'88 timeframe - the ECO seems to be Apr '84); the M7165's were both B14, and the M7164's were F4 and J04 (I think - that was on a sticker in the right place, and I don't see anything else). > joined with the 40-pin and 50-pin cables) along with the cab-kit up for > sale The two short cables are pretty generic, from what I can see. Ground plane backing, but other than that, stock 40- and 50-pin flat cables. Those should be easy to make. The bigger issue is the cab-kit, which is almost unobtanium. There's a guy on eBay selling a bunch of NOS UDA50 board sets, which include a cab-kit, which is, I'm pretty sure, the same as the KDA50's - alas, the KDA50 User's Guide doesn't give the part number, so I can't be positive (the UDA-50 one is 70-18455-6K). Alas, he wants a ton of money... > Thanks Jay for getting cctalk back online, well done! Ditto! Noel

Vintage UNIX computers/servers for SALE-auction

by janprunk＠gmail.com

Hello ! Vintage workstations and servers for sale/auction in Slovenia, Europe. Below is the list of hardware, if you are interested, please read the details regarding the sale terms at the end of the list. For anything else you wish to know, please direct all questions regarding equipment to E-mail janprunk-at-gmail.com and not to the mailing list. 3 x HP 712 1 x Switch Hubstack JEHI-24 1 x Power Macintosh 7500/100 2 x SUN Sparcstation 4 1 x HP 9000 PC-308 (XT) 1 x Digital DEC 3000 1 x HP Terminal (monitor) 700/96 1 x Digital DEC 2000 1 x HP 9000 E35 STATUS OF THE EQUIPMENT : Equipment is being sold AS IS, meaning there is no facility to test it ! Computers should be in a working condition, some were even used by me personally, but consider them being sold as a DEFECT, due to its age, limited skills and lack of my time to exclude warranty terms. I am able and willing to provide the photos of the exterior, but please don't ask me to open up the machines to photograph the interior or components, boot up the OS, test the condition etc. I can provide exact model and serial number if that will be helpfull to you. Some computers come with the original hard drive inside and some don't. AUCTION: You are welcome to bid prices for this equipment. To limit the sale to serious bidders, I will only consider bids above 100 EUR per computer, if there are more bids for the same computer I will consider the highest offer. I haven't placed the equipment on EBAY at this time, because that would make me obligated to ship the computers even with a 1 EUR bidding win price and that would just mean too much work and no pay for me. PAYMENT: I am able to accept bank wire as a preferred method, cash or cheque, cryptocurrencies, such as Bitcoin but I am unhappy to accept Paypal due to its refundment policy which always sticks with the buyer. SHIPPING: I would prefer if you can do local pickup, however that might not be possible for people who don't live near Slovenia. I am willing to ship the equipment by mail, but be advised that Slovenia foreign parcel shipping is very expenssive so it wouldn't cost less than 80 EUR to ship the computer across Europe, due to its weight and dimensions. Shipping outside Europe would probably even double the amount, but if you are a serious collector I will also consider that option if you are willing to pay for shipping. I might have the accessories for computers - keyboards, cabling ... but consider the workstations being sold without that, as shipping the workstation + keyboard can be a problem, due to different dimensions and it would need to be packaged into two separate packages, therefore doubling the shipping costs aswell. ADDITIONALS: Keep in mind that bids below 100 EUR would just mean too much work for me to organise the shipment so I would rather not deal with it. I hope that the computers can find a new home with some other collector. For anything else you wish to know, please direct all questions regarding equipment to E-mail janprunk-at-gmail.com and not to the mailing list. I wish you all a happy bidding ! Kind regards, Jan Prunk PGP Pubkey http://prunk.si/0x00E80E86.asc
