Hi folks, I've just re-joined the lists after a... uh, something like a four year absense, I guess! It's good to be back, even if it is a little more verbose than I remember. I looked through the recent archives and didn't see this covered already, forgive me if I missed it -- I've been unable to contact www.trailing-edge.com or simh.trailing-edge.com for the last week or so. Is anyone else able to get through? Does anyone know if something is wrong? Or, alternately, does anyone know how else to get in touch with Tim Shoppa to ask, other than his trailing-edge.com email? Maybe I'll resort to snail mail. -Seth -- "It looks just like a Telefunken U47! Seth Morabito You'll love it." - Frank Zappa sethm(a)loomcom.com

M9312 boot roms (again)

by GOOI＠oce.nl

Sorry, I never bothered making or downloading those ROM images. I must admit that it would be a nice addition to the M9312 page that I have put in the PDP-11/34 folder ... if Pete gets his hard disk data recovered (or read the PROMs again), I will gladly add that to my site (if Pete does not object).

Free (UK): PCB developing tanks

by pete＠dunnington.u-net.com

Anybody want three developing tanks for making printed circuit boards? They're intended for developing/etching/tinning and each holds almost 9 litres (about 1.9 gallons/2.3 US gallons) of liquid when working. Each is 490mm x 140mm x 370mm high (400mm including the lid, with its handle), and they're designed to be fitted into cutouts in a bench top, though you could stand them on a low bench or in a (large) sink. One is a plain tank, one is fitted with a thermostatically-controlled heater, and one has both heater and air-bubble tubes, and I have two controller boxes for them (which have been kept indoors, in the attic). I'm never realistically going to use these, as I have small fit-in-a-cupboard dishes and a heater I use for small boards. I got these from the University about 10 years ago, intending to put them in my new workshop. Unfortunately by the time the workshop was built I had a lot more computers, electronics, and mechanical things, there wasn't room, and The Boss refused to give up space in her utility room. They've been stored where she keeps garden stuff, ever since, but I've been given an ultimatum. If you can collect them, let me know by Monday that they're wanted otherwise they'll go to the local tip. If I know someone will take them, I might persuade The Boss that they can remain in her utility room (now they've been cleaned up a bit) until Christmas, but suggesting any longer would probably have fatal consequences (for the tanks, not me; I'd probably get away with crippling injury). -- Pete Peter Turnbull Network Manager University of York

It's completely and totally free, and unlike some competing OSes, it's also completely and totally Classic. You can download the distribution tape images from ifctfvax.Harhan.ORG and write the actual tape yourself (if you have some other machine capable of writing tapes, given all the stuff you have I'm sure you do :-), or if you want to give some support to the project that develops and maintains the said OS, you can order an official distribution tape from Harhan (probably still much cheaper than any membership fee or license).

Anyone got an HP Paintjet printer?

by ard＠p850ug1.demon.co.uk

This is going to seem like an odd question, but here goes... I've borrowed a Paintjet (colour inkjet) printer from HPCC (as you probably all know I am somewhat invovled with that club) with the idea of taking it apart, figuring out how it works, etc. Yes, the club do know I do that sort of thing :-) So far, so good. I've figured it out, made notes, and put it back together. Problem is, I can't get it right... Here's the problem. There's what I'd call a 'pressure bail' that holds the paper against the platten. It carries a transparent plastic window. And that window seems very loose. So loose, in fact that it rubs on the ink cartridges when you move the carriage. And when the carriage moves to the far right (parking position), the window drops so far that it jams the carriage, which then can't move back to the left. The problem is compounded by the fact that I don't know that it was correct before I took it apart. I do know I've got no bits left over. I also didn't dismantle that part of the printer (I did remove the logic board and mechanism from the case, I did dismantle the mechanism far enough to remove the carriage and motors). I can't see any obvious places where something (like a spring) should go, but equally the finish on the tabs of the window (I did remove that _after_ I discovered the problem in an attempt to find it) doesn't look as good as I'd expect from old HP. Maybe some tabs have broken off. So my questions are (if you have a Paintjet, original version) Look at the windw in front of the platten on top of the machine. Does it seem to sag at the front edge, or is it forced up against the inside of the case. If you can remove the cover (I can tell you how to do this, it's easy and doesn't need tools), I'd like to know just what supports the window. Are there any springs or spring wires/leaves on the front of the pressure bail? Are there any 'extensions' to the tabs on the window at the front of the bail? If I know thrre's something missing/broken I can have a go at making/kludging it. -tony

NCR Tower PSU again

by julesrichardsonuk＠yahoo.co.uk

Hmm, getting somewhere; found a dead triac near the input which was supposed to bypass that 10 ohm resistor that was burning out once the PSU had started up. Presumably the intention was to allow the PSU to start a little more gracefully. Nice bodge story: I just found out why the system wasn't starting up at all. It had been semi-dismantled since it had died years ago; I'd reassembled it recently when trying to get it running again. After much wiring tracing I've just discovered although the cable between the control panel and the backplane is keyed at both ends, at one end the connector was on back to front. That hadn't stopped whoever assembled it at the factory from hammering the keyed connector backwards into its socket! I hadn't noticed how bent out of shape the socket was when I reassembled the machine; I'd simply lined up the key on the connector with the relevant slot on the socket, then spent ages trying to work out why the PSU wasn't even trying to start up when the switch was operated. Grrr! Now, I'm getting a good 5.1V output, but there's a nasty wheezing noise (not a whine!) from somewhere on the main PSU board. The +12V and -12V rails are seriously up the spout. With a light load (just a couple of fans), the fans spin up for a couple of seconds before everything shuts down for a couple more seconds, then the cycle repeats (the wheezing sounds like breathing at this point!). With no load the wheezing's constant and the PSU doesn't shut down, but -12V rail is at -4V and +12V rail is at +5.3V. I'm going to load the PSU up with an (unwanted) hard disk in a moment just in case it's not firing properly because of not enough load - not sure if I want to risk any boards in there at present though, but of course it's possible the PSU's not operating properly because there's some feedback from the absent CPU board not present... Any widsom appreciated. Sure don't like that wheezing noise - cap or wound component? Fault or just something not being driven at the right frequency? cheers Jules

8x300 subroutine call mechanism revealed

by tomj＠wps.com

Thanks Al, for giving me a retro-headache, that chip's architecture is even worse than I remembered :-) It's truly a terrible architecture. The subroutine call mechanism is a trivial software convention, you could do it on any machine that had one unit of storage to dedicate. Only 32 one-deep calls are allowed; 32 is an 8x300 limitation. The trick is that CALL and RETURN are macros. Here's how it's done, example trivial code fragment: 0100: CALL subr / This jump subroutine... 0102: ... / ...returns here, 0103: ... 0200: CALL subr / and this call... 0202: ... / ...returns here. subr: code here ... RETURN One 8x300 register is set aside for the return linkage mechanism, let's call this RETN. The macroassembler does the work. A local (to the assembler) variable, let's call it R, increments with every CALL macro expansion, arbitrarily from the top of the souce file to the bottom. At the same time, a jump table, call it JUMPS, is constructed where the Rth entry is [pc + 2], that is, the address to return to after the call. (2 instructions are needed to do the CALL.) CALL expands to: xmit R, RETN / store R in register RETN jump subr RETURN expands simply to: XEC RETN, JUMPS / execute JUMPS[RETN] I'm certain I have the syntax wrong, no matter. The jump table called JUMPS looks like: JUMPS: jump 0102 / first call + 2 jump 0202 / second call + 2 ... / etc It would be 'interesting' to cobble up a mechanism capable of recursion, but likely it would be larger than many subroutines. It could certainly be done though, and worse things have been shipped.

analog computer support information

by dwight.elvey＠amd.com

Hi I'm not sure if I understand your question. You simply change the time constants to be in the range you are looking for. If the original used a 10K and it was 0.1 seconds, using a 100K will make it 1.0 seconds. The capacitance values scale similarly. Do remember to remodel things so that the equation is all integrations and no differentiations. Doing integrators is preferred for these problems. I don't think you change the gains unless you want different responses. You only change the time constants so that you can watch the response. Of course, each step is linear so that you and divide at the input of a stage and the multiply the output if there is a compliance issue. Otherwise, just control the size of your stimulus.

Moving the card to slot2 made no difference. The 2 SCSI cards in the other machine are not the same. One worked but it seemed to hang when configuring SCSI devices.

Most have SRM cards and extra memory. I have no working drives available (see previous submissions). We do have a number of keyboards and monitors. Here's the deal, Winner take all, Winner picks up in Lexington KY. No shipping. Good news is that they are free and there is not an immediate need to move them. Let me know if there's any interest and I will do an inventory. Thanks Max

Damn, that's too bad, they are great monitors. But you can use a serial terminal like your VT220 as well. You can either connect a terminal as the "alternative diagnostic console" to serial port 3 (traditionally called the printer port) with a BCC08 cable (trivial to make yourself), or if you want to be more fancy, you can permanently convert a VAXstation 2000 into a MicroVAX 2000 by changing a jumper inside (and removing the color video option if there is one), in which case it will have a serial console on port 0. Ports 0 and 1 are more difficult to connect to when you don't have the official DEC423 converter box that went with MV2000 systems, but not impossible if you are willing to make the (very hacky and non-standard) cable yourself. If you use the alternative diagnostic console, you can't unplug the console cable or it will halt (breaks cause halt with the alt diag console), but if you get the console on port 0, breaks and unplugged cables are no problem and you can run headless. The connector pinouts and lots of other juicy technical info (enough to write your own OS should you so desire) are in the MV/VS2000 Technical Manual, EK-VTTAA-TM, available on Manx (giant scanned PDF unfortunately). > I'm planning on reviving my retrocomputing hobby, and want to start by=20 > setting up the VAXen (is VAXen the proper plural?) Yup, it is. > Does the list have any suggestions for > 1 ) The setup of these machines See above about the console. Your OS choices are quite diverse. There are VMS and Ultrix, and if you are willing to make some DEC-disapproved hardware modifications (specifically, hook up a SCSI disk, then buy 4 27512 EPROMs at your local Fry's and program them with a modified version of KA410 firmware that has SCSI tape boot code replaced with SCSI disk boot code), you'll be able to run 4.3BSD-Quasijarus as well pretty soon (as soon as I write the machine-independent SCSI code). If you want to run NetBSD, OpenBSD or Linux, someone else would have to tell you about those since I do not and will not touch those OSes. Or write your own OS! This is one of the few machines of that era for which DEC published a real technical manual. I hope this helps, MS

pinout for smith corona ultrasonic 350 messenger?

by rigdonj＠cfl.rr.com

I picked up a fancy Smith Corona Ultrasonic 350 Messenger electronic typewriter a few days ago. It has a DB-9F connector on them back. I'm hoping that it's a RS-232 port so that I can use it for a serial console. Does anyone know anything about these or the pinout for it? Joe

HP 64000

by GOOI＠oce.nl

>From my memories from the eighties. The HP64000 crate can be filled with an ICE for a target CPU and (with the appropriate software) you can do real-time emulation. With the addition of the logic analyser board (and again some system software) you can combine the software emulation with hardware signal tracing. For example: define an event to occur (start trace etc) when the hardware signals have a certain state. Also, on the screen of the HP64000 you can see timing diagrams of al the signals. Neat stuff if you must do hardware debugging of the target. If the hardware is OK, the analyser is seldom needed.

Blinking Light program for PDP-11

by GOOI＠oce.nl

The drawback of using the RESET instruction 000005 is noticed when you have RX01 or RX02 drives connected to your system. The INIT signal on the UNIBUS, asserted by the execution of the RESET instruction causes all peripherals attached to reset. For an RL01/RL02 drive you can probably see a lamp flash on the front of those drives, but the RX floppy drives "clunk" with their heads on INIT. >From experience, running this little blinkenlight program on an 11/35 is not fun for long, unless you are deaf because the sound of engaging/disengaging the RX heads is *not* fun. Sorry that you had to wait a little longer until Guy sent you that program.

And many >states put them on driver's licenses. > >The problem is that all of this is legal -- it shoudn't be. Here in NJ, the Emergency Service records are all handled via SSN as a person's ID number. So every EMS class I take, I have to put down my name, and my SSN on a sheet of paper that sits at the front of the class... open to anyone who is in the class, or anyone at any of the schools that handles the paperwork (or anyone that sees the paperwork). If I fail to put down my SSN, the course won't go down on my state records, which means I'll be shafted out of class credits needed for various recerts. Often these same sign in sheets ask for phone number and address as well (I now put down the # and addy of my department rather than my own, but most people put down their own). Some even ask for DL #!!! (I never put that down except on classes that involve driving) And I'm still convinced that the time I had my ID stolen was from one of these classes. I use a combination of my name for my EMS records that I don't use for ANYTHING else... and the time I had someone take out a credit card in my name with my SSN, they used that particular combination of my name. Of course, I'll never know for sure, because the local police felt it was too low priority to bother investigating. I pushed them for 6 months on it before I gave up. (meanwhile, the bank told me they had a 2nd address and phone number on the application, but that they couldn't give it to me, but they COULD give it to a police department... so really all the cops had to do was make one lousy phone call!) The state started a new ID system a few years back, but no one (including the state itself) has changed over to it for general use (partly because the ID is only for fire fighters, and they make up only one portion of the EMS personelle... someone that just rides an ambulance has no desire to take a fire fighter class so they can be issued an FFID). I keep hoping the state will expand the FFIDs to a generic EMS-ID, and change over to that for everything... it irks me each time I have to put my SSN down on the sign in sheets. -chris <http://www.mythtech.net>

Mercury computer???

by rigdonj＠cfl.rr.com

Anybody know anything about these? They look very modern and very high tech. Most of the units are in grey aluminium boxs about 12" wide, 10" and a couple of feet long. They have quick disconnect fluid couplings on them. I opened one of the boxs and they have some regular looking boards in them and some boards that are encased in thin aluminium boxs. Both the boards and the enclosed boards have two small fluid quick disconnects on them too. One of the encased ones was open and the card inside has two Intel i860XR ICs on them along with a bunch of LSI brand ICs. One of the other boards has soem HUGE ICs on it. They're almost 2 1/2" square and have Mercury Computer Systems marked on them. ALL the ICs in these are heavily gold plated and very expensive looking. I think the part number on the one large box that I opened was Z1117. All the other boxs had different numbers. Joe

Jeffrey Worley was and is a great guy, a real hero in my book. OK, he killed his dad, so what. If Jeffrey killed him, it was most certainly for just cause and the guy deserved to die. He was most probably being a dictator in the house and tormenting Jeffrey (by interfering with his ClassicCmp work, by telling him to get a Weendoze job, or somesuch); and he was rightfully overthrown and executed for his crimes by the oppressed citizenry.

header pin out for pdp-11/44 console (M7090)?

by brad＠heeltoe.com

Hi, Does anyone have a schematic for an M7090 (11/44 console card) or know the pin out of the 20 pin header for the console cable? I searched and could not find anything. I don't have a console cable for my 11/44 and I'm sick of coding in TI DSP assembler and need a pdp 11 fix. I have all the parts to make a hack cable but don't know the pinout. I suppose I should read the 11/44 manual :-) where is the console baud rate set? (ok, ok, I'll go read the manual). -brad

Blinking Light program for PDP-11

by wacarder＠usit.net

I seem to recall seeing a little program that can be toggled into a PDP-11 (35/40/45/etc) that will create a "rolling lights" pattern on the front panel console, where the lights roll to the right and left, off and on. Can anyone here on the list point me to that program? I know that I saw it somewhere on the internet. I'd like to toggle that program in on my system. On another note, I got my ASR-33 working, connected online via 20mA DZ11 connection to my 11/34. I had the send/recv wires crossed. It works perfectly now. Ashley

But let me guess, if you are guilty of murder you likely lose any privacy rights attached to your SSN. That's why, in this case, it's out there for all the public to see. Just like they post the names, photos and addresses of sex offenders on websites. But I guess that's "totally inappropriate" too. "Totally inappropriate"? In my book murder is "totally inappropriate." Making public the SSN of a convicted murderer, even if done intentionally, just isn't. At least, as the target of your "totally inappropriate" attack, that's my current take on it. -W

RT-11 installation

by trash3＠splab.cas.neu.edu

The RX01 used the DX driver and the RX01 used the DY driver. If the driver on the floppy does not match the actual drive, it will not boot. So, a normal RX01 floppy will not boot in an RX02 drive and vice versa. However, I THINK that if you used the wrong density floppy but put the right driver on it (An RX01 floppy with the DY driver as the boot driver) it will work, but that is not how the distributions were set up. Of course there are games you can play, like toggling in a bootstrap, but I don't think that was being asked. Well, anyway, that is what I remember of it, please, anyone, correct me if I'm wrong.

Lots of people have names that are common with other people, and these databases are largely used by employers to do background checks on potential employees. Providing the SSN greatly reduces the risk of a false positive that could result if you only ran a search by name - in other words, if the SSN doesn't match, it isn't the same person. As some may recall, when Schwarzenegger was campaigning for governor in CA there was a woman who accused him of groping who was immediately identified by the Schwarzenegger campaign as having been previously convicted for prostitution. Turned out that the hooker was a different woman with the same name. All they needed were a couple of SSNs. -W

I have plans to visit the North Island later this month, but for a few weeks, I'll be here, hanging out.

I use a current limiting supply and set it to about an amp or two. I place the supply across one of the power planes ( corner to corner on a solid plane and end to end for E traces ). I do not place the supply form power to ground, just across the one plane. I then place one lead, of a meter that reads 5 digits on a 200 mV scale, from the opposite rail that is shorted two. One then simply traces for a null on the plane with the current flow across it. On a plane, I take a piece of string to mark the line of the null and then put the supply on 90 degrees, across the same plane. Where the new null line cross the old string is the where the short is. This method will even work if the short is +1K, if that is the only current flow. I once showed using it on a burnin board with a 10K resistor that was in wrong out of some 400 sockets and about 12 resistors per socket. I was able to zero right into the exact resistor. The principle is that one uses the plane as though it were a variable resistor and the short was the contact. If one measures along the resistor to the contact, the voltage will be zero at the location where the contact is made. This is much easier to read than CRC's method since you are looking for a null, rather than a stop in the change of the voltage. It also has the advantage that it won't blow an intermittent short so you can find it. It is more sensitive than the HP current probe for power planes ( having used both methods ). It also is run at a very low voltage so there is no chance of damaging other parts. I publish this method every now and then but most people don't think about how it works and will tend to forget it. Such is! Dwight

OT: good CS textbooks for a DIYer

by rcini＠optonline.net

Hello, all: I'm looking for recommendations on CS textbooks for myself...I'm embarking on sort of a DIY CS degree :-) Anyway, if anyone could recommend decent first-year and/or second-year books on algorithyms and data structures in C/C++, I would appreciate it.

The path drawing the current will continually drop while non-drawing paths will remain at a constant voltage drop. On multi-layer boards you measure drops to the Vcc pins of the bugs and map the drop. CRC

Finding shorts in boards

by julesrichardsonuk＠yahoo.co.uk

I've got a board here with a short between ground and the +5V rail (actually not quite dead - I'm getting around 10 ohms between the rails) Any useful tips for finding the fault? It's a large board, multi-layer, lots of silicon on it unfortunately :-( Are there any particular components that are likely to fail in this way that might be found across PSU rails? (decoupling caps, certain ICs, crystal modules etc.?) Given a suitably sensitive meter is it sensible to assume I can try and home in on the short location a little? (I've found readings between GND/supply on various LS chips of anything between 9.5 and 12 ohms so far) I've checked the board for particles of anything that might be causing the problem, plus I'm halfway through ruling out any of the socketed ICs. Of course if it's a problem with the multi-layer PCB itself... eek! (do these ever fail in such a way though? It's a commercial board which used to be fine) cheers Jules

A couple of freebies...

by auringer＠tds.net

While cleaning the past weekend, I came across a couple of things that I thought I would try to find a home for. 1) Manual for a Aydin Controls "Slow Scan Analog Patriot Series High Resolution Color Monitor", March 1985. I also happen to have a model 8831 monitor, which is covered in the manual. I do not know the working condition of the monitor, but the cosmetic condition is O.K. The manual contains schematics and troubleshooting information, so I would think making the tube work should be possible. The tube is big, and needs to be picked up on the east side of Madison, WI. 2) 1985 Sharper Image catalog. The only thing I thought was interesting was the ad for an Omnibot 2000 robot. Anyone interested for the cost of shipping? Jon

Burroughs Panaplex display data needed

by tomj＠wps.com

I recently acquired a virgin Burroughs Panaplex display, and can't find data for it. It's a 24-line, 40-column display, tube only. Character matrixes are 5w x 9h (!) so it'll do decenders. The only markings are a simple "N-0008" on one edge. It's got double staggered rows of pins on all four sides. The whole thing is about 8" x 10". I know how (on paper) to drive panaplex displays (it's nasty) and would love to work up a nice display with this thing if I can find pinout data. Any ideas?

FYI: also there: 2 LP27 lineprinters, 1 TU81-plus tapedrive I was able to swing by Bob Donovan's company on the way to a family function and took a few pictures of the VAX 6000. He talked a bit about apparently three other parties trying to take the machine and giving up. the machine is weeks away from the scrapper. I will be going by in about a week in a normal hatchback car to pick-up what I can. Since the *entire* interior of the car, seats included, is about the size of the VAX, I will dismantle it to accomodate. Alright Jokesters, that's the VAX, not the car. This means that the other 1/2 of the machine is likely going to be scrapped, even though it is in better shape than my car. Just to let you know. If there is another thing I can do, let me know. It's a 6100. quick photos of the visit at http://www.panix.com/~allain/V6000/ John A.

Just for the hell of it I googled the club I hung out with in the late 1970's or early 1980's, NECS. According to one reference (Springfield Mass. Library) their website was www.necs.org, which is now owned by one of those horrid 'buy this site' parasites. I can't even remember anyone's name! What a shame. Used to meet out near 128, meet then go to some local late-night restaurant. The club ran a BBS, ("NECS"...), how I got in touch with them in the first place.

Take a look at CWRU-PC/IP: ifctfvax.Harhan.ORG:/pub/micro/msdos/net/ For dial-up you'll also need a Class1-emulating packet driver for your SLIP or PPP. Ask your ISP if they could perhaps set you up with SLIP instead of PPP as it's much less painful under DOS. MS, who has connected to Inet from DOS in this manner prior to starting Harhan in 2000.

Calcomp 1039 plotter in UK

by djg＠drs-c4i.com

If anybody is interested email plotter(a)pdp8.net which will forward to the plotter owner (spam protection). Email I got offering it: Got your details from the internet. I have an old Calcomp 1039 plotter which I need to dispose of. I note that you may be interested in PDP bits but don't know if this is the sort of beast you may want! It certainly used to be connected to a PDP in the distant past. It has most of the original accessories in their large & small black boxes plus umpteen rolls of media If you want any info please feel free to call me on 01727 875191. leave a voice mail if absent. Or if you know of anyone else who may want such a thing rather than being destined for the local tip! Regards Graham Simms In Hertfordshire.

VCF 7.0 Pictures

by dwight.elvey＠amd.com

>From: "Wayne Smith" <wayne.smith(a)charter.net> > >I have posted a few pictures taken during VCF 7.0 at >http://webpages.charter.net/jpepperman/VCF%207.0.html. > >-W > Hi Of course my exhibit wasn't even noticed or photographed. As usual Sellam gave me half a table and most just figured that I was part of the exhibit next to me ( North Star ). Since my machine was also a woodie, ( much rarer than a North star ) it just blend into the background. Maybe next year I'll be noticed. Dwight

Phllips Logic Analyzer Manuals

by aw288＠osfn.org

I have a set of operators manuals for the Phillips PM3551/10/30/50 and /70 logic analyzers (early 80s). One is in a binder, the other is just bound - a total of about 1 1/2 shelf-inches of information. Anyone need these for a couple of bucks plus shipping? William Donzelli aw288(a)osfn.org
