Real PDP11 model question

All I can think of is the obvious -- that you couldn't put some of the quad-height devices in a serpentine backplane, but that isn't an 11/03 vs. 11/23 issue. There are backplanes (H9273-A and H9275-A) where you are supposed to change jumpers. Unless someone has meant that the 11/03 is 16-bit and the others are 22-bit, but they still work in 18-bit backplanes. -- Pete Peter Turnbull Network Manager University of York

Real PDP11 model question

by Innfogra＠aol.com

I had a couple of SMS boxes in my warehouse that had hard drive and a floppy drive and I think a 4 slot qbus backplane. One had 8 inch drives and the other 5 1/4 inch drives. When I got them I think they had 11/23+ CPUs. They were 19" rackmount and about 5 inches tall. Fairly deep as thery were designed for 8 inch drives in front with the cardcage in back. I think you could put an 11/73 card in one. Zane, did you buy those from me years ago? They sold in one of my final warehouse sales. Paxton Astoria, OR

Rescue of a life-time.. or the year at the very least.

by pat＠computer-refuge.org

So, after forgetting to bid on the 11/780 that was on eBay, ending on Sunday (I slept in 15 minutes too late), I decided to drop the guy a message and see if he had another 11/780. Much to my amazement he did, and when I asked if he had any other DEC equipment, he replied that he had an 11/750 (which it turned out he had two, but I only took one of), and that I should "bring the largest truck I could find, and he'd get me loaded up. So, I spent Sunday night looking at options for rental or borrowed trucks, and times, and decided that it was cheap enough to get a 15' Budget Truck (which was a lot cheaper than what Penske or UHaul wanted for a similar size), and after finding out he'd be leaving Friday for a month, I decided I needed to go get the stuff now. So, I reserved the truck for Tuesday. Having done this "move computer that weighs a lot" thing a few times before, I put together some tools Monday night, 10 or 12 ratchet straps, hard packing foam to keep stuff from scratching too badly, tape for marking things, along with some cardboard boxes, ziploc bags, masking tape and a sharpie and 2 friends (well one was my roommate). We left here at 8am on Tuesday morning, picked up the Truck in Waukesa, WI, around 12:15, and got to the place before 12:30, avoiding too much bad traffic driving through Chicago a bit after morning rush hour. The building the machines have been stored in for the last decade (or more) is an old limestone building in downtown Waukesa, which according to the guy who was trying to clear out the stuff used to be a brewery - fitting for an old building near Milwaukee. : ) Anyhow, the guy is a landlord, and some company was using the building as storage. He said that there used to be a lot more machines there before - some had been scrapped, and he had been able to sell some things using eBay. So, after getting there we loaded up the 11/750, and UNIBUS expansion rack that appeared to go with it, and headed to the "large pile" to look through more things. In that pile were the two 11/780s, another 11/750, a Systems Industries disk rack with some sort of controller, which I'm guessing goes with the VAXen, a 5ft DEC rack with a Cipher tape drive in the top and a UNIBUS box at the bottom. Aparently, attached to all the VAX hardware was some Intergraph and Synercom CAD "workstations", which consisted of an approx. 4x2x3ft (WxDxH) box that contained the "main electronics" with a 4x2 ft digitizing tablet, and two monitors which were 20-24" on top of the main 4x2x3ft box. The Intergraph ones were somewhat plain, with the two monitors in one enclosure, but the Synercom ones had a very "Bat-Cave" feel to them, and were separate monitors on swivel posts. If I had room for one, I would have grabbed one of them. I didn't get a chance to look too closely, or take a picture either, which I do somewhat regret. In the back corner behind that stuff was a CDC 14" disc cartridge drive of some sort (which was rated 1phase, 208VAC.. I didn't have room for it, or disk carts), a Sun 3/180 with a pair of 800MB-ish Fujitsu SMD drives and a Sun-branded 9-track tape drive. The final item I found there was a Data General Eclips MV/4000. It had two 19" rack mount disk drives, which appeared to possibly be SCSI (?), a 9-track drive, and the CPU. So, I managed to bring home one of the 11/750s, its expansion cabinet, one 11/780, the Systems Industries disk rack, the DEC rack with the Cipher drive and UNIBUS box, the Sun 3/180 rack, and the DG Eclipse. All in all, I'd say I made out fairly well. The truck was probably a bit overloaded (I'm certain we had more than 3500lbs of stuff in the truck, which what it's "suggested capacity" was, as the leaf springs on the back tires were arcing upwards slightly, instead of downwards... I'm glad it's a rental. : ) The ride home brought us right through rush-hour traffic on Chicago's loop (I-90/94), and we got back here around 10pm; we left for home around 5pm after some lunch. I spent the next day (Wednesday) working all day, and then came home and unloaded the truck with some help from friends. We removed as much weight as we could from the racks before taking them down the ramp, which was actually wide enough to be of some help, and was strong enough to hold up to the mostly-intact 11/780. I've got a picture of the 11/780 up, with the front doors removed: http://computer-refuge.org/compcollect/dec/vax/11780/vax11780-front-open.jpg I don't yet have pictures of anything else, nor do I have most of it reassembled yet. I spent this afternoon testing the 11/780's power supplies with a dummy load - they all appear to work - and then running a 30A 220V line from where there used to be an electric range in this house to the garage so I can try to power it up. I noticed when I was working on the VAX (I had to look at what cards are in it!) that it has a full complement of 32MB of ram (8 x 4MB boards), made by EMC Corp, along with a memory backplane power supply by EMC and a battery-backup power supply box for the memory, which was the same as what the 11/750 used for its memory backup (the 11/750 I got also had a memory backup battery power supply). I took the batteries out of those, along with the TODC power supply, as I'm quite certain that they need to be replaced. If I can remember, tomorrow I'll be fetching a new battery for the TODC power supply in the 11/780 and fitting that. Tomorrow I'll be finishing that up, wiring up an adaptor so I can plug in the 11/780's PDU (I "fixed" it a bit - moved plugs around - so I can use it with 1-phase 220 instead of 3-phase 208), and potentially re-racking some of the rest of what I have. I hope to have the 11/780 cleaned up and ready to try powering up before the end of the weekend. After that will be the Eclipse, the 11/750, and the Sun 3/180 (in no particular order). As I set up my 11/780, I'm gonna try to put together a page on it like the 11/750 page I have on my site right now, I'll probably do something similar for the Eclipse too once I get that far. One thing I noticed after getting home is that I should have engaged the shipping locks on the disk drives... so I don't know how well they faired, but that'll be something I can worry about later, as it's too late to do anything about it now. In one of the UNIBUS boxes (presumably for the 11/780) I got, there was a Emulex UC18 UNIBUS SCSI card, so if all else fails, I should be able to put some low-power disk drives (even FH 5.25" drives are low power for it! :) on that thing, and I *think* (but am not yet sure because I haven't checked it out) that the Eclipse also uses SCSI disks. I realize how much the UC18 is probably worth, and would consider selling it if I had another form of mass-storage for the 11/780, but I'm not sure I do.... that's something I still have to look into. Since the stuff I got is now blocking my roommate from parking in the garage, I'm gonna have to start purging some of the smaller / less interesting things I've got laying around here, so look out for postings of stuff available from me soon. As well, if you're interested in the Intergraph or Synercom stuff, or those disk drives (sorry I didn't look closely enough for a part #), you might want to look the guy up via the 11/780 auction and send the guy a message. Just remember that someone already has the other 11/780 and 11/750 going to him. :) Pat -- Purdue University ITAP/RCS --- http://www.itap.purdue.edu/rcs/ The Computer Refuge --- http://computer-refuge.org

BA356 SCSI

by Pres＠macro-inc.com

Just got an Emulex UC08 SCSI <--> QBus. Has the S handles on it and all I have is BA23. So, I'm waiting for drill to charge so I can drill out the 4 rivets that hold on the S handle stuff. Not having any experience with SCSI, I have a question. Could I use a BA356, with 8 bit personality module, with RZ29B-VW 4gb drives, with the UC08? From what I can find, the drives are 50 pin, wide SCSI, but I'm guessing that's what the personality module would handle. The UC08 has 2 HPDB50M connectors. It has 2 SCSI ports, typically one TMSCP, the other MSCP. If the BA356 and those drives should work, anyone know what the connector is on the BA356 going to the host adaptor? Ed K.

There are *many* loader programs and they're easy to write. This particular one was one of mine and I don't think the source ever made it anywhere public. Fortunately I have at least 20 floppies containing the source and one of them is surely still readable!

I know, look in the sources of ACW kermit and see who ported it :-) I was amazed (and depressed) that the ARM port of Kermit was simply my ACW port with another layer added to fake out the ACW routines, which themselves were just a veneer over BBC OSBytes! What a mess!

Intel 86/330 pictures

by rigdonj＠cfl.rr.com

Hi All, I brought home two of the Intel 86/330 computers that I recently bought. (The things are BIG and I could only get two in the car at one time). I was told that they all contained bubble memory cards and the one that I checked had one but neither of the ones that I brought home had one :-( Anyway I took a few pictures of the two that I brought home. Here are some links; Front <http://www.classiccmp.org/hp/Intel%2086-330/front.jpg>, Back <http://www.classiccmp.org/hp/Intel%2086-330/-back.jpg>, One of these has the iSBC86/30 CPU card with a iSBC337 NDP daughterboard and a Real Time Clock daughterboard made by Linear Systems <http://www.classiccmp.org/hp/Intel%2086-330/86-330w-rtc.jpg>, they both contained iSBC215 Winchester Hard Disk Controller cards with iSBC215 Floppy Disk Controller daughterboards <http://www.classiccmp.org/hp/Intel%2086-330/WDC.jpg>, one system contains an iSBC028 RAM card <http://www.classiccmp.org/hp/Intel%2086-330/iSBC028.jpg>, the other contains an iSBC012CX RAM card <http://www.classiccmp.org/hp/Intel%2086-330/isbc012cx.jpg>, both systems contain iSBC86/30 CPU cards <http://www.classiccmp.org/hp/Intel%2086-330/isbc86-30.jpg>. One system contains an iSBC88/45 Advanced Data Communications board. This is the first iSBC 88/45 that I've seen. According to a site on the net, it has 3 HDLC/SDLC half/full duplex communication channels, optional ASNCH/SYNC on 2 channels, Supports RS232C, CCITT V.24, or RS422A/449, has a 8088 8 MHz microprocessor, On-Board DMA supports 800KB baud operations, Self-clocking NRZI SDLC loop data link interface point-to-point multidrop, 16KB static RAM, Software programmable baud rate generation.

Rotating memory data recovery

by tomj＠wps.com

OK, I'm very close to needing to suck the data off the main memory of this LGP-21 before I reform caps and all that electronicky stuff. It would be nice to have a 16-bit MHz A/D system, but I don't. Any *practical* suggestions for someone with an extremely limited budget? I also don't have time to build one, though it's within my skills. (The LGP-21 I have has a rotating magnetic main memory; bit-serial 80KHz clock, 64 physical tracks (128 logical), 4096 31 (32) bit words, NRZ or NRZI. I figure A/D sampling of the raw head signal at 8 to 10 times the original clock rate will allow offline data recovery, should I smash data on later CPU powerup.) The platter is driven by an AC motor. It powers up completely independently of the rest of the computer, so I can easily do all this before I begin the restoration. I planned on rigging up a fast opamp buffer/amp, clip-leading it onto each head in turn (the heads are low-Z; I do know about ground, common-mode, etc), and taking 2, 4 or a dozen snapshots of each track. I'll make the track snapshots available to anyone who wants them. If there's anything there, it would be really nice to see 41-year-old-data. Practical suggestions appreciated...

Panasonic RL H-1400 - Information Needee

by spectre＠floodgap.com

> About the best I could do is to snail-mail the ROM to > you. -or- I'll be in San Diego tomorrow - Monday. That's a very generous offer, but there are two problems ... first I'm presently in San Bernardino :( and won't be back in San Diego until Sunday, and only Sunday at that. The bigger problem, though, is actually getting the capsule out to read it. I opened up my HHC-4 and dug out the NYL capsules, which I hadn't examined too closely before. They *seem* to be regular 24-pin EPROMs (with an NYL sticker conveniently covering the UV window; they're 4K TMS 2532s, for those interested). The problem is not the chip, which seems to be a regular old ROM. The problem is that the DIP legs are wrapped *around* the capsule carrier, and digging the DIP out is probably going to damage the chip. I could try wiring it into my Jason-Ranheim Promenade, but I don't see much I could attach the wires to on the capsule side, and soldering leads directly on to the DIP legs is right out because I'm very worried I would ruin this first example of this capsule I've ever seen! Is the BASIC ROM similarly "wrapped" on yours? If it is, perhaps there's another way of doing this -- some way of reading out the contents of the ROM using the HHC itself. If you've got the printer, maybe if we could scrabble some way of printing out a hex dump, assuming this BASIC is halfway sane and has PEEK and POKE or a moral equivalent. We'd just have to figure out where in memory, but this is easier than it looks because it would have to start on a 4K page boundary, meaning we'd only have to glance at 16 possible areas. If one of them has BASIC keywords, we've found it. All this to say I would be *very* antsy about damaging a *very* rare ROM with my relatively novice EE skills, despite the fact I want it *very* much! -- ---------------------------------- personal: http://www.armory.com/~spectre/ -- Cameron Kaiser, Floodgap Systems Ltd * So.

Yup, the drive is pretty much toast. No telling how long it's going to stay up this time. I'm headed back home from the datacenter to start copying stuff off the drive. Loosely translated, anyone who wants to chip in for a new hard drive for the classiccmp server, let me know. If the servr is down, I can be reached at jwest(a)ezwind.net Thanks. Jay

Fwd: RSTS strange problem

by ron.hudson＠sbcglobal.net

More info.. I can edit files if I am logged in as 100,1 but if I change files in 1,2 they disappear at running $shutup. I visited the computer history museum today and showed someone there the problem, and they suggested I "crash" the system instead of running shutup... tty.cmd remained afterward. It seems like shutup is doing somthing to try to protect the system by deleteing an edited system file.

[Posibly OT?] Tek 321A scope needs help....

by r_beaudry＠hotmail.com

Hello all, I recently became the new owner of a Tek 321A scope, but it needs some repairs. Also, I have no manuals, so if anyone could loan me an operator's manual or service manual so I could make a copy, I'd appreciate it.... The main issue is the display. There is what I can only describe as a "cloud" that runs vertically along the center of the display. Varying the intensity and focus does vary this cloud, but it is still present. Also, the trace line is visible, but very out of focus. Wider at the edges, and narrower in the middle. I can take a picture if this makes no sense... I don't know the working condition of the scope, but it was put in a large bin for disposal. It's possible that it was just tosseed in, so it may have been banged around a bit. It seems a shame to toss this unit, as it is in pristine physical condition. The battery holders are very clean, and the unit has no dust or dirt that I can see.... If this is a common problem, or if it seems fixable, let me know what to try.... Rich B.

Salvaging HP Laser Jet series II

by millenniumfalcon＠cableone.net

Well, with the help from members of this list I finally got one Series II running and one not tested but saved back and two that were FUBAR. So, because I cannot bear to throw anything away all at once, kind of like the story of the three legged pig, i decided to scavenge what I could of the two Series II before pitching them. I just pitched the Series I, the 3, and the 4. I saved anything that had a wire connected to it and put all the plastic, sheet metal and gear trains into the trash on the theory that the gear trains looked tough enough to not be a failure point. I saved about half the weight and half the storage space. The fuser bulbs looked to be in good shape so I don't think they were the cause of the "50 Service" error I was getting. At least the filaments were not broken. I am assuming that this is like a halogen bulb and you don't want to touch the glass surface of the bulb. Is there a recommended cleaning procedure??? Too bad the fans are 24 volt not 115 volt. I could have used some 115 volt fans for my Kilowatt Linear I am building. Are there any parts I missed? Are there some parts I should have dumped?

VAX 11/780 help needed.

by pat＠computer-refuge.org

So, I've got power run now, and am trying to get the machine up and running. After I figured out what baud rate it wanted (and reset it down to 1200 baud from 1800 baud), I've been trying to figure out a problem... So, when I connect a terminal to the console port, all I can get is an address: 173002, followed by an "@" (the ODT prompt). Trying to examine the addresses using ODT fails. So, it looks like the bootstrap PROMs are not accessible for some reason. From what I see, it appears that they are actually contained on the CIB (Console Interface Board) in the KA780 CPU. Can anyone verify this, or have any suggestions what I should check? The power supply bricks all have their "POWER NORMAL" lighs on, and seemed to have a good 5V output from testing with a dummy load and DMM. Any ideas? I'm a bit stuck here.

Classiccmp website?

by rigdonj＠cfl.rr.com

Anybody know what has happened to the Classiccmp website? I checked some of my webpages there yesterday and the files are still there but most of them are now blank! The files are NOT missing and they still have the right file size but they're blank. I just tried to access the site a few minutes agoo but now I can't even get a connection to it. I e-mailed Jay yesterday and asked him about the problems but haven't gotten a reply. Joe

Any Honeywell fans?

by dan＠ekoan.com

At a recent hamfest I picked up two sets of what appears to be Honeywell training material. Each set consists of a slide projector tray, cassette tapes, and a manual all in a fold-open case. The first set is labeled "Digital Computers and Software" and is dated 1979. It has 80 slides in the tray and comes with two cassette tapes and a booklet. The second set is labeled "Delta 1000 Control Interpreter Language" and is dated 1980. There are 46 slides in the tray and there is one cassette tape, along with a booklet. All of this stuff is marked "Honeywell Proprietary." I'm generally much more interested in HP stuff, but this looked unusual enough to pick up. Contact me off-list if you'd like more information. Cheers, Dan www.decodesystems.com/wanted.html

Osborne 1

by ddl＠danlan.com

To answer a few questions that have been asked about the Osborne 1: -I'm not asking anything for it, but neither will I spring for shipping and packing. I expect this could be expensive. I am not willing to deal with international shipping at all. -I'm in Gloucester, MA. Pickup would of course be best. -It worked last I played with it, but that was 15+ years ago. -The latches are on the sides. And to answer some questions that have not been asked: -The original user's manual is included. -There are a number of disks, but no originals. -I believe it has the double density controller.

Panasonic FDD number decode?

by cfandt＠netsync.net

Has anyone information on decoding the model number suffix on a Panasonic 3.5" floppy drive? The number is JU-257-14PF. I was told it was a 720K drive when I bought it some time ago but it seems to act like a 1.44MB unit. Need to confirm as I want a 720K for an industrial OS-9/68K system I'm thinking of dragging out of storage. Controller only talks 720K. Controllers in PC's use connector pin two, IIRC, to select lo/hi density. Is my drive selectable by internal jumpers for 720k only/1.44MB only (and is there such a drive available in general)? I don't care to hack the hardware on my nice OS-9 system just to make something work. I can find 900+ hits on Google at this moment for the JU-257. Several different suffixes are shown and many indicate 1.44MB capacity. There's but only one with the -14PF suffix which appears in the search under the inventory of Searchlight Tech.com site. No descriptive help there. Methinks this is in fact a HD drive instead of the desired 720K and I was, basically, ripped off. Neither Matsushita nor Panasonic website searches yield anything on even "JU-257". Long obsolete, evidently. Thanks for your help. -Chris F.

Guess what the hurricane(s) left behind!

by Innfogra＠aol.com

I will be happy to pass on the SW when I get to it, and to all also.. ISIS should run on the 330, too. The 330s origianlly were 8086 SBC with separate disk controllers for the HD and 8" Floppy. The 330 had a Priam 3450 *" HD (30 meg) and a DSDD 8" floppy and a 6 slot backplane. My 380 has a 286 SBC with a 14 slot backplane in one box and the HD, floppy and a tape drive in a second same size box.Twin 50 pin cables interconnect. The combo HD, Floppy and tape card is the 214 I think. There is usually a console port on the SBC. Other serial IO was on other cards. The hard drives have a manual parking lever. If it is not set do it immediatly. I would love to hear what the configuration of them is. The SBC board numbers had a slash number. 86/30, 286/10. The 320 is multibus II isn't it? A VME type connector (but not the same pin configuration). Paxton

Nigerian scams

by Innfogra＠aol.com

This is a new variation of a scam. I have gotten two on my posting of my HP 110 outfit on the HP Museum classified ads that I mentioned earlier. Both wanted me to name a price, they did not care what it was. One wanted to send me a certified check for over the amount with me rebating them the overage. This is the letter I mentioned on the list. The other wanted to buy anything else I had and would pay me with a credit card. All they were going to provide was the credit card number and the expriation date. There was a strong implication they would pay an inflated price. It was an open invitation to Fraud and I reported it to Yahoo where the offer came from. It was interesting that they would make arrangements for the equipment to be picked up. A news story on the local TV told a story of a T Shirt company that got an offer similar to purchase the 9000 T shirts and paid with two credit cards. One went through but the other bounced and the owner of the business found out it was fraud before he shipped it, overseas. However. The people that ordered, when they did not get their T-Shirts, threatened violence against the owner if he did not ship, several times. I think it best not to respond to such offers, and report them to their apparent (but usually not real) source. I think it is important to report all Fraud to the internet providors. Paxton Astoria PS I was concerned that I got two fraud offers directly related to my posting of the HP110 on the HP Museum Classified ads. It shows that thre are many people out there trolling collectable computer and calculator sales with the intent to defraud.

I am in Port Charlotte with the American Red Cross and the damage around here is unbelievable. I went last weekend to visit the In-laws in Boca Raton on the east coast of Florida and there is quite a bit of damage there as well. Red Cross is scrambling for volunteers and is trying to shuffle equipment around. It is beyond comprehension for me on just how Red Cross can possibly keep up. Yes, Florida is getting slammed this year. Joe Heck

more RSTS/E strangeness....

by ron.hudson＠sbcglobal.net

ooh no it's that Hudson fellow again. Someone take his PDP 11 away, he don't know how to use it.. There is a problem when I am logged to my RSTS/E(simh) in as [1,2]. I recently have been trying to edit my tty.cmd file, I am using teco, I edit the file making a change, I save the file with the teco command ex$$, ($=escape). Once out of teco I type tty.cmd to verify my changes. I then use pip to copy tty.cmd to tty.bak and tty.old . Then I shutdown RSTS/E and restart - to make sure my changes work. On reboot RSTS can't run tty.cmd - claims it can't even find it. Of course the startup procedure stops at that point so a lot of other things don't get done (loading error managers, spool managers, batch manager and defining CCL are the main things) While in this state directory (run $direct) cant find tty.* none of the tty files I copied remain.. I even tried saving a file named cmd.tty and it vanished too. I type a new tty.cmd from scratch (using teco or pip) and reboot and now **all** of them are back. 8^P What's up? I think I need a nice RSTS/E boot camp.
