Shure AMS8000 mixer.

by dwight.elvey＠amd.com

Hi If someone on the list replies to this ( or these ) fellows, I'd like to know if they get any response. I've tried to send to two of these types request in the past and gotten no response. ( they didn't seem to care that I had what they were requesting. ) In fact, I'd like to know if anyone that has sent to one of these off list request has ever found that they where actually talking to a real person. I'll have to admit that this particular request looks real. Still, from my past experience, I have my doubts. The two request that I replied to in the past also seemed as valid as this one. As you will note, I have no problem responding to those I recognize as being on the list or just responding to the list in general. These off list request tend to be about as close to form type request as the various Nigerian scam letters I receive. They're all a little different but all seem to have some common elements.

Various IBM PS/2 models available

by vcf＠siconic.com

Is anyone interested in IBM PS/2 models? I have a bunch of various models available if anyone wants them for $10 each plus shipping: Model 50 Model 50Z Model 35 SX ...and some others. I'd rather they go to someone rather than be scrapped, which is what's going to happen to them by the end of the week. So make an offer if you're interested. -- Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org [ Old computing resources for business || Buy/Sell/Trade Vintage Computers ] [ and academia at www.VintageTech.com || at http://marketplace.vintage.org ]

H89 disk imaging

by dwight.elvey＠amd.com

>From: "Dan Lanciani" <ddl(a)danlan.com> > >Did you ever get this going? I'm looking at a different approach, reading >the single density disks a track at a time in double density and then doing >the data separation in software. > > Dan > Hi Dan Unless you know something I don't about disk formats, you can not read double single density format with a double density controller. It isn't that you'll just get 16 bits instead of 8 bits, things like sync makers will not work. In any case, I currently have a method of transferring hard sectored 40 track disk images to and from the following platforms to a PC running DOS: Z/H90 w/ serial card H89 w/ serial card H8 w/ H8-5 serial/cassette card H8 w/ H8-4 serial card ( Note: The H8's may be either an 8080 w/ PAM8 or a Z80 w/ XCON8 ). The DOS machine needs a serial port. My setup can also be used to bootstrap a machine that one has no access to disk with code on them. You only need the blank disks to copy the images to to bring up a system. Dwight ps I hope Dan is on our mail list because I no longer email directly to queries from off list. See my previous post.

Anyone have/know of Persci drives, parts

by Watzman＠neo.rr.com

Subject: Re: Anyone have/know of Persci drives, parts 1. There are no microcontrollers on the 270/277 series drives (I believe that there were on the later 299 drive) 2. The board has a huge amount of analog circuitry on it, both for the r/w head and the very complex servo system, and is not easy to troubleshoot. 3. None of the components on the board, including the 50 or so ICs, are socketed. No argument that the boards ultimately could be repaired, but it's not nearly as easy as your post suggests. Plus there are 4 other major but smaller boards on the drive in addition to the large main board. > I need some Persci 8" drives (model 270 or 277) and/or parts to repair them > for some systems. The part that I need most is the very large circuit board > on the right side of the drive. Anyone know of a source? [I'm sure that Are you actually missing this board? If not, then surely the existing one can be repaired to component level -- AFAIK the only custom part is an 8048 microcontroller, which presumably could be copied from one in a good drive (I don;t think the 8048 has any security features). -tony

Can anyone identify this portable?

by dave04a＠dunfield.com

I have received an email from a gentleman asking if I can identify a portable computer that he used to own. The machines ran DOS (MSDOS), and appears to have a standard PC/XT style keyboard layout. It is a "box" machine line the early IBM portable or Compaq portable. It has a monochrome screen (CRT), somewhat to left of center. Left of the screen is "open space". To the right of the screen are three 1/2 height 5.25" drive bays running horizontally (on this machine it has a floppy, a hard drive and what looks like a filler plate). Below the drive bays there are four "knobs" and what looks like it may be a switch. On the far right (beside the knobs) it looks like they keyboard cable comes out of a hole in the front panel. I have posted the picture he sent at: http://www.dunfield.com/pub/portable.jpg Anyone know what this is?

Old EPROM questions again, EPROM Programmer

by wolfgang＠eichberger.org

Hi all, first I want to thank you for your nice and fast help with my Commodore Pet ROM problem. Now I have a little question for my personal Interest: There were many Eprom Programmers back when the 2532 etc. were actual which were designed for popular homecomputers (I own one for my Pet too and know of many for C=64). Many of these devices were "homebrewed gear" or sold as kits. But after lots of time googling around I haven't found much stuff about this old eproms. Okay, I have at least a bunch of datasheets and some schematics where ex. the 2532 were used and learned a lot of early 1980's hardware basics :) But I could not find some schematics (and software) of Eprom programmers dedicated to this chips. My (maybe dumb) question: Does anyone have some schematics and software (would be great) for a little homebrewed Eprom Programmer which works with a standard PC parallel-port or ISA slot? This would be a great project for rainy winter days :) Best Regards, Wolfgang ==================================================== Ing.

Dragon 64 fixing...

by julesrichardsonuk＠yahoo.co.uk

Finally found the five minutes to see if my Dragon 64 works. It doesn't. I get a white screen with a black border (which seems healthy enough), then in the centre of the screen a few random characters (some with inverse video). Occasionally after a reset the random characters don't stay together but occupy random locations toward the middle of the screen. I assume (having never seen an operational D32 or 64 before) that it should say "Dragon 64" or something, implying that character generation is screwed - but why the random characters should jump positions sometimes I don't know (unless the design of the reset circuitry is not very good) One obvious fault I found was that pin 6 of the 40 pin 6847 IC was broken and had been badly repaired in the past (such that I don't think the joint had held), but fixing that hasn't made a difference. The fact it was ever broken at all suggests that someone's been fiddling inside the machine though... I notice IC17 (a socketed 18 pin DIL) is missing - should it be? None of the DRAM is getting warm (suggesting failure), and the fact that there's something approaching normality on the display suggest that the power rails are OK and the CPU's at least operating. Of course presumably a RAM fault could quite easily explain random characters and locations though, but doesn't explain the stable white screen / black border (unless that's done in low level video hardware). Any ideas? If I can get this thing running then it's another potential for the CGE show this coming weekend. cheers, Jules

z8000 segment scheme question

by David.Kane＠aph.gov.au

The Z8000 segmented address scheme has two forms. The long form that you described uses two 16 bit values (registers or memory locations). The short form uses a single 16 bit value with the 7 bit segment number in bits 9-15 and an 8 bit offset into the segment in bits 1-8. Bit 16 of the first 16 bit value is a flag which indicates long or short segment address. This is important for memory addresses operands as the CPU can get an address word operand from memory, and then based on the flag bit can decide if the next word must be read to get the complete long address. In either case the segment address is located in the same place in either a short segment address or the first word of a long segmented address.

Booting real RT11 on a Heath H-11

by bob＠jfcl.com

I have a Heath H11A (LSI-11/2 CPU!) with the Heath WH-27 floppy diskette drives. It boots and runs HT11 (Heath's crippled version of RT11) just fine, but when I try to boot a real RT-11 v5 RX01 diskette it just halts. I thought that the WH-27 was RX01 compatible. Am I wrong, or is there some trick that Heath put in (maybe in the WH-27 boot ROMs?) to keep it from working? Thanks much, Bob Armstrong

IM6100 project plan options (was OSI 560Z: DEC PDP-8 clone using 6100 & 6502)

by bob＠jfcl.com

Hi Guys, I built the SBC6120 (a PDP-8/E clone based on the HD6120 chip, http://sbc6120.SpareTimeGizmos.com) but a bunch of the people in the SBC6120 group also have IM6100 chips, sometimes tubes of 'em. We've been having a little discussion about what to do with them on the SBC6120 mailing list, and when I heard about this thread I thought I'd open up the discussion. To start off, I can think of a couple of ways to go with the 6100: * Another machine with a real lights and switches front panel (a simplified SBC6120+FP6120). To save money we'd have to use cheap metal handle (e.g. "Altair style") toggle switches instead of paddle switches. There'd be no fancy silk screened faceplate like the SBC6120 - if we had any faceplate, it'd probably be some laser printed graphics sandwiched between two clear sheets of plastic (again, "Altair style"!). You might even have to drill your own faceplate - STG might not offer a precut one. * An Intercept Jr clone, including the octal keypad and octal display. Maybe even powered by 3 or 4 "D" cells like the original Intercept Jr. * A single board computer with an onboard EPROM to talk to a terminal using something like LSI-11 CODT. No lights, no switches. Basically a simplified (and less capable) SBC6120. All of the options would have 4K of memory and a console terminal interface. They'd run FOCAL-69, DECUS CHESS, or any other 4K paper tape software. No mass storage and no OS/8. Would anybody like to cast a vote? Does anybody have another idea? Thanks, Bob

Booting real RT11 on a Heath H-11

by mbg＠TheWorld.com

>> The only problem is that the boot ROMs, which are on the WH-27 card, >> don't know how to boot a RL02. Any ideas? > >I seem to remember that if you configure RT11 with the RL11 handler >(DL.SYS IIRC) and boot that (e.g. from RX01 floppies) you can then do a >BOOT /FOREIGN DL0: to boot the RLs. You can also do the following: Make sure you have a bootable RT volume with the DX.SYS and DL.SYS device drivers. Make a copy of it. For the copy (and I'm assuming it is mounted in drive 1 with the system in drive 0), issue the following command: COPY/BOOT:DL DX1:RT11SJ.SYS DX1: (or substitute the monitor filename for RT11SJ above). What this will do is create a diskette which, when booted, will actually boot the corresponding unit of the DL drives. If you place this in drive 0 and boot it, the system will be loaded and will run from DL0.

2.10bsd on an 18 bit '11?

by mbg＠theworld.com

As the designer and implementor of the Qbus and Unibus Ethernet handlers for RT, I can say that for the NU handler to work (with either DEUNA or DELUA), the version of RT you use must have the support for Unibus Map. If not, it won't work. I have to admit that I don't remember which version of RT was the first to release with Unibus Map support... (so many versions, they all sort of blur in memory over time...)

The Future of Bletchley Park & the computer museum - comments wanted!

by julesrichardsonuk＠yahoo.co.uk

All, English Heritage spent a great deal of time recently surveying Bletchley Park (in particular buildings for which there was little information in the public domain, either due to the original information being lost or still classified) Said report and survey has now been published on the English Heritage website - see: http://tinyurl.com/45avu Importantly, comments are invited by English Heritage. Recently a response to this turned up in a newspaper local to the Park: http://tinyurl.com/4aqgo Some would say that currently the most "significant parts" of the site as projected to the public revolve solely around the Enigma, at the expense of everything else for which the Park has been known over the years. Lots of exhibits have already been scaled down and squeezed into much smaller premises; the military vehicles section is being demolished despite the part which such vehicles played in the war. The future of the Computer Museum and the rebuilt Colossus within H Block (and indeed the storage area within D Block) are very much uncertain, and a move to smaller premises is certainly not out of the question. Nobody seems to know the exact future of H Block but as it currently houses the museum and Colossus, and was the site of the world's first purpose-built computer room, to my mind it seems both the ideal location for its current occupants (with great scope for expansion!), plus a valuable bit of the UK's heritage which should not be lost, and also of great historical importance to the information age. (Note that as the whole site expanded during the war, D Block took on a lot of the work of the smaller Huts and so played a vital role, and C Block held an enormous Hollerith punched card section, so they are not without merit either; both currently lay almost derelict though) Realistically I'm not sure what anyone can do other than leave suitable comments for English Heritage about the importance which the Park played within the computing scene in order to ensure the survival of the huge amount of artifacts which we have. (Given the central location within the country my feeling is that it's also an ideal site for some form of national computer museum, but I don't know if that's relevant or not :-) I'm sure this will be of interest to UK residents on this list anyway, and quite possibly many of you further afield. (the less said about the way in which our current Government treats the heritage of this country the better, of course!) cheers, Jules

FS/FT : Fluke 9010A

by stephane.tsacas＠gmail.com

Hi all, I recently bought several Fluke 9010A. Some are running version 2, some are running version 3A which I beleive is the latest one. Is it easy to upgrade from v2 to v3 ? All I need is to copy the eproms ? They came without the "logic probe" can I build one myself ? Anything special about it ? I have something like 6 units, if someone is interested, drop me a mail. I'm looking for some pods: z80 at least. I'm in Paris, France, so the shipping cost can be an issue if you're not in Europe (except for the pods which are not so heavy). Thanks Stephane ps; I'm looking for someone on a 10 Mbit/s or faster internet access in Europe or US for a simple ftp throughput test.

Just scored a CDI-1030

by cmcnabb＠gmail.com

The guy who surpluses old equipment in our warehouse gave me a call this morning. He had a CDI-1030 APL/ASCII portable acoustic thermal "teletypewriter" that someone had found in a closet, and wanted to know if I had a use for it. Upon physical inspection, the terminal is in great shape - no dents, dings, scratches, missing keys, etc. It is built into a very rugged (and heavy) samsonite suitcase and even had an unopened case of thermal paper with it. The Property ID numbers were no longer in the database, so it could not be surplussed through the normal channels (auction) since it could not be tracked. I could either take it or the surplus property guy would have to send it to the scrap yard. The decision was a no brainer, and I now have this old heavy thing sitting here in my cube. Now, how to explain this latest acquisition to a spouse who is already complaining about the amount of "junk" in the basement....

IBM 029 punch in Colorado

by vcf＠siconic.com

I've been speaking with Louis, the fellow who posted a message recently about an 029 punch in Colorado. He's a very terrific guy. Anyway, as much as I'd like to get an 029 punch for my archive, I don't have the space or the funds right now to acquire it. So that being said, is there anyone else in the Denver, Boulder, Fort Collins, Longmont, etc. area that can at least rescue this thing and hold it for someone (possibly me) for the short term? Louis said it was sitting in the rain but this thing ought to be able to take that just fine. Some parts will probably rust a little but that can be cleaned up with a little bit of labor on a nice Saturday afternoon. Please come forward if you can rescue this thing and/or want it. Louis can't promise that he can get the owner of the recycling facility to hold onto it for very long. -- Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org [ Old computing resources for business || Buy/Sell/Trade Vintage Computers ] [ and academia at www.VintageTech.com || at http://marketplace.vintage.org ]

vax 11/750 help

by bert＠brothom.nl

Hi All, Today I was trying to get my VAX-11/750 to work. I figured out how the baudrate for the console terminal is set (and what it is set to), but I cannot find any of the other parameters, such as the number of databits, parity, and number of stopbits. Can anyone here tell how these are configured or, if they are hard-wired, to what value they are set? Also, are the schematics for this machine available online somewhere? I did search for it a few times, but never found it. If not, is there someone who can make them available? TIA, Bert

z8000 segment scheme question

by vax3900＠yahoo.com

I picked up one of my computer books today and read that z8000 uses one 16 bit register to hold the 7 bit segment number and one register to hold the 16 bit offset. The strange thing is that the segment number is hold in position of bit 9-14 other than the bottom half of the first register. I goggled and found complaint about this scheme but no one explained why it was designed so. Could somebody on the list tell me why? __________________________________ Do you Yahoo!? Yahoo!

DEC AXV11 A/D Board Connector Pinout Wanted

by dj.taylor＠starpower.net

As you can tell from the heading I have one of these boards. In the DEC Micronotes there are some simple programs that show you how to acquire data with it, however I don't know how you connect the board to outside sources for sampling,etc. Anyone have info? I think I saw something in the Vax 4000/200 manuals that talked about a cabinet kit for this board - a UDIP - does this ring any bells? Doug

AT&T catridge

by Sharp51482＠aol.com

These were for Terminals that AT&T made in the mid 80's. The terminals had a built in telephone set. There was a analog model for use with POTS lines and a digital model for use with System 75 and 85 PBX systems. If you have no use for it, I'd add it to my collection as I have several AT&T personal terminals 510A and D's. Another intresting feature of these sets was they were all equiupped with touch screens.

Early timesharing/BBS systems

by robertw63＠hotmail.com

Time-sharing services were pretty common in the early 70s when powerful computers were difficult to afford for even medium-sized companies. Dec pdp-10s were often used. The company I worked for in the UK at the start of the 70s used a computer bureau called TSL (Time Sharing Limited) who offered both an interactive Focal-like language and compiled Fortran. The terminal was a standard 10cps teletype with paper-tape reader/punch. Careful checking of input was needed because of the high costs involved. As an example I recall making a single error in a several thousand line circuit analysis program (we were designing early integrated circuits using it) and the resulting failed compilation cost £80 ($140) - quite a lot of cash in 1972! The username and password from those days is so burned into my brain that I still frequently use them today! As recently as 1981 I was managing a multi-terminal IC design department time-sharing over a muxed 2400b line to a CDC supercomputer for Spice analyses with the output on the noisiest drum printer I've ever sat beside! Thankfully an in-house Vax then appeared. Bob Adamson >-----Original Message----- >From: Richard A.

HP 7200A plotter

by wacarder＠usit.net

Ok, I'm going to surprise everyone and ask a question about a non-DEC item. Does anyone here have an HP 7200A plotter that they would like to get rid of? These were used in the 1970s. Ashley P.S. Even though it's a non-DEC thing, we used to have one connected to our PDP-11/40. I can't seem to find many references to these on Google or anywhere else.

My VCF trip (long)

by jwest＠classiccmp.org

The Burlington VCF trip was my first VCF. I enjoyed myself immensely. Three cheers for Sellam for putting in the work to organize the thing. I did talk to Sellam a bit about possibly having a VCF central in St. Louis - I want to bring my cherished HP2000/Access system. I refuse to cart that system across the country to either coast, or even to KC :) Sellam, I'll be in touch to discuss some stuff about seeing if we can have a VCF in St. Louis sometime. The hotel (mariott) was wonderful, and it was so great to put a face with the email address on so many of the people I've been talking to here over the years. I will definitely make it to a few more VCF's, but hopefully with less travel problems. Ah yes, so many have asked about "The Great Trailer Incident(tm)". Here's a synopsis of my trip to VCF and what all went wrong - presented here entirely for your amusement and as a lesson so that others (including myself) may avoid my screwball missteps. I left St. Louis on Wednesday the 14th, about 8am. Drove non-stop to Washington PA, about 600 miles and spent the night in the Red Roof. My van was loaded with two HP racks, and in tow was a 5x8 flatbed trailer with two more racks and a few 7906 disc drives. The van and trailer were handling wonderfully. I checked the tires on the van before leaving Saint Louis, but neglected to do that on the trailer. The trailer I had just gotten about 6 or 7 months ago for $500 (because it included a PDP-11/45 on it at no cost). It had driven back to St. Louis from TN just fine then. So anyways... I left Washington PA thursday morning to drive the remaining 600 miles to burlington. I was about an hour or so from burlington, headed east on I-84, just 4 miles from the massachusetts border when the tire blew and disintegrated. I got out an looked and there was a few shreds of rubber on the wheel, the majority of my tire being about 30 feet behind the trailer. Pulled off the highway and pondered if a normal car jack would lift a trailer that was pretty heavily loaded, or how I was going to possibly get to the spare van tire with the van fully loaded, and if that tire might fit the trailer, etc. etc. My adventure had begun. I called AAA and said "I'm not a member, but I'd like to be". They laughed and said they wouldn't sign me up for membership AND place a help call at the same time. How helpful. But they at least said they'd get me the phone number for a service station in my area. I had virtually no cellphone battery left. After getting transferred around to quite a few different service stations, one finally had a human voice instead of an "I'm sorry, we're closed" recording. Cool. Told them I needed someone to come out with a certain tire, and where I was located. They said that because of the location/highway I was on, I HAD to have police come out before they could get out there. Huh? I told the guy I had no cellphone left, and would he please call the police for me. He said sure. Almost two hours later, still no police. What fun. It was around 11pm by then and I was getting pretty testy. So I called information, got the police phone number. They said they weren't located in the area I was in, and would transfer my call to another police station. Click... dead line. This happened about 3 or 4 times. Apparently police stations can't transfer calls without hanging up on people. So next call I got the original police station to give me the phone number for the right police station. Wrote it down and asked him to transfer me... click... hung up on again. So I dialed the other police station directly. Fast busy. Waited a while, fast busy again. This cycle repeats a few times. Finally called the original police station, he transferred me and joy of joys this time it went through. The police officer at the new station politely got all my information, location, etc... then told me that I was talking to the Danbury police, which were on the entire opposite side of the state of connecticut from where I was. They offered to transfer me (ARGH!) to Troop A, who were in my area. The kind people at Troop A said they didn't handle the area I was in, and transfered me to some other Troop (F-Troop I suspect). When the transfer went through, I received a recording "I'm sorry, but our offices are closed. Our normal business hours are..." ARGH!!! So I called the original police station, again told the guy where I was, that I had no battery left, and needed him to get someone out there, then hung up. About an hour later, an officer pulled up behind me and asked what the problem was. I suspect it was too DARK for him to see the SHREDDED TIRE at his feet. I told him I wanted someplace to come out with a tire and replace mine, or tow to a 24 hour service station, etc. He then politely asked why I called the police, that I should have called a towing service. ARGH! That IS how I started out, and the towing service told me to call the police first. What fun. The officer informed me I had two choices. Leave the trailer, and come back in the morning and get it with a new tire, or call for towing. I wasn't going to pay towing to burlington, over an hour away. I couldn't get a close hotel, because I had prepayed with late checkin for the mariott at burlington. I didn't want to leave the trailer on the side of the road. But not because of what the officer said... he asked what was on it (no, I didn't jokingly say 'cocaine'). When I told him "antique computer gear" his eyes got wide and he cautioned me about theives going up and down the highway picking stuff off vehicles/trailers left behind. Of course I told him that I wasn't concerned about general theives... I was concerned about my fellow collectors who may also be driving into burlington along I-84 that night, THEY would certainly stop and pick the trailer clean *GRIN* (just kidding). I decided to leave the trailer, chain it with padlock to the guard rail on the side of the highway, and drive the rest of the way into burlington and deal with it tomorrow. I finally got to the mariott at about 1am or so and the bed never felt so good. The next morning I got up, and drove the van to VCF so I could empty it out and not haul that weight back to the trailer. As I was pushing gear in the front door, I met Sellam and asked him if he could make sure the stuff made it in the rest of the way, that I had a flat tire on 84, and had to go retrieve it - so I'd be late to the show but would be there. Then I went to sears just up the street from the service center, bought a tire, and headed out an hour away on 84 in search of my trailer. Found the trailer, jacked it up, grabbed the rim, and spent about 1/2 hour looking for a service station that would put the new tire on the rim for me. Pulled in to something in studbury? and the mechanic said no problem, fired up his tire machine, and... *POOF*. Showers of sparks everywhere. His machine was not going to be putting tires on rims anytime soon. So, he directed me to another garage a few miles away. They got the tire on the rim just fine. As the mechanic put the tire in the van, I asked "how much do I owe ya?" fully expecting the guy would do it as a freebie, or maybe 5 bucks. No... he wanted 20 bucks - cash only. At this point, money was no object, I was 100 miles away, missing a computer show I drove 1200 miles (one way) to go to. GRRR. Drove back to the trailer, put the tire on and thankfully pulled away. Of course, when I put the tire on I got the bright idea that perhaps I should check the other tire on the trailer too. It was in really bad shape, probably would have gone anytime soon. So I limped back to burlington, van in tow, never exceeding 40 mph cause I didn't want the other tire to blow. A few fellow highway drivers weren't particularly happy with me driving at that speed, and made that point quite clear with various hand gestures wild gesticulations. So when I got to VCF I unloaded the trailer, then dropped the trailer off at sears so they could replace the other tire. Went to VCF and had a total blast!! When I got into VCF, apparently the story of "The Trailer Incident(tm)" had spread like wildfire and grown substantially. I think I overheard one incarnation that involved my trailer being on fire and me being put in jail. Hehee... amazing how a story grows through retelling. Then much of the VCF folks went to Victoria's Station for dinner - where the portions were huge and quite good! I had to leave during dinner to pick up the trailer (Sears closed at 8), but then came back for some good conversation and story swapping with my fellow classiccmp'ers. After dinner I met in the lower parking lot of the marriott with Dan Cohoe, William Donzelli, and Evan Koblentz. Was rather funny to see three vans pull up into an empty parking lot, starting moving a bunch of "big boxes" between them, then all go speeding off. Hummm. I got alot of really great DEC and DG stuff. You would THINK this would be the end of the story. NOT! I had taken four empty HP racks to the show... and confirmed with all four collectors before I left st. louis. Of course, at the show, one of the collectors didn't show up at the show at all, and the other one apparently left before I got there late friday (due to the above). So, I was stuck with two large HP racks, sitting in Sun's building. I couldn't load them back to my van, which was already full (and scheduled to get more at bobs and bills). So I was scurrying around asking Sellam for any ideas for disposal, etc. Finally Dan Cohoe stepped forward to help me out and took both racks. One is still destined to go to the person who wanted it as they aren't too far from Dan C. The other... well... haven't heard from that collector yet :) Dan Cohoe - THANK YOU! I had to leave VCF a little early, because I had gear to pick up from Bob Shannon in Leominster, then more gear to pick up from Bill Dawson in Washington PA on the way back. Stopped at Bobs and loaded up, then headed for Washington PA. After about 120 miles, I noticed I itched. I was getting bug bites. I looked across the dash of the van, and there were flying ants (or something like that) crawling over the entire dash, the seats, my legs, etc. Apparently some of the gear I picked up at VCF or later had a low rent housing project for these bugs going on inside of it. Opening all the windows while going down the highway, and then (later) closing the van up tight at night, seemed to get rid of them. It was pouring down BUCKETS of rain, and I had to pull off the highway several times as visibility approached 10 feet. When I got to Washington we loaded the Reality into the trailer, and inbetween breaks in the rain got it all tied down and ready to roll. As I was laying on the ground underneath the trailer hooking bungee cords up, Bill mentioned to me as an aside "Um, you do realize you're laying in a bed of poisin ivy don't you?". I now have the rashes to prove I did NOT have any idea. I got perhaps 2 miles from Bills house before the trailer started fishtailing wildly. Cool! More fun! So I pulled over again but this time couldn't see anything at all amiss. So, I called Bill, and trouper that he was... he drove up to help. After scratching his head a bit, he stood on the tongue of the trailer and found the problem. A seriously negative amount of tongue weight. We were pretty sure we had distributed the weight well (especially with the 11/34 up front), but, apparently not as the power supply for the reality is built into the bottom of the rack, and it is VERY heavy. So, I turned on the emergency flashers and followed Bill to a nearby closed gas station that had a large covered area. We spent the next hour and a half taking everything off the trailer, re-organizing how it would go back on, retarping, tie-down, and re-bungee'ing everything. Finally I was ready to continue home. The thing drove great on the highway now and I settled in for a long, relaxing drive back towards home - st. louis. There was really heavy fog around PA, and just as I was settling down into "watching the miles tick by" mode..... Suddenly I see a large piece of scrap metal on the road in front of me. It came out of the fog, was no way to avoid it. I patiently braced for the dragging of metal, and my patience was rewarded with a wonderful shower of red sparks going up both sides of the van, from the piece of metal being drug under the van. Cool! All this fun, and a fireworks show for free to boot! The metal looked like a piece of aluminum siding all crunched up, or maybe part of a corrugated tin roof... something like that. I continued to drive for about 500 feet, because the metal piece looked pretty small/flexible and I figured it would work it's way out from under the van in just a few feet. It didn't. So I pulled over on the shoulder and sat there for a minute, contemplating what egregious sin I had comitted in a different life that merited this amount of trouble. I was trying to figure out just how (un)safe it was going to be, crawling under a van in the dark, on a fast highway, trying to unwedge a piece of metal debris from under the van. To my suprise, when I got under the van, there was no metal, and no damage, in sight. Apparently the metal HAD come out just when I pulled over to the shoulder of the road. The rest of the trip home to St. Louis was, in fact, totally uneventful :) Again, it was really great to meet the folks there at the show. Everyone was most friendly, helpful, and it was just a plain blast to put a face with the name, and just sit and chat with people about this hobby. Hopefully, people won't hold my grumpy attitude the first day at the show against me, now that they see just what my thursday night/friday morning was like! Well, I'm off to sort through old email, the business cards I collected at the show... and try to somehow get back to restoring some more of the machines in my collection. VCF St. Louis anyone? Oh - by the way - if I had to do it all over again, with the same problems as above, I would. VCF was THAT fun. However, next time I will be taking along a spare tire for the trailer :> Regards, Jay West --- [This E-mail scanned for viruses by Declude Virus]

B800 vs B1800, etc

by stevew＠ka6s.com

Well - to answer a series of questions ;-) There were two separate operating systems available for the B1000 series. There was the standard MCP (that was similar in operational characteristics between the B1000 and B2000 series at least) It didn't have a common code base, but things worked in a similar manner from the console (SPO in Burroughs speak.) The other OS was "CMS" and ran on the B800/B1000 series. CMS was from the Liege plant if I recall (Hans - is this right??) and I remember them showing up in Santa Barbara where we were bringing up the B1965 at the time. We had our MCP up with a couple of issues when the guys came in >from Liege to bring up CMS. It had one issue which was a new instruction we'd added on the B1965 if I remember, other than that it came right up! So from my understanding you could run the same applications on the B1000 and B800 series. Now - difference between B18XX and B19XX. Mostly cost reduction and reimplementation in TTL. The B19XX may have been faster (a blistering 6Mhz ;-), likely had a larger memory sub-system, and I think they had the same size instruction cache. The B19XX machines had a 4Kbyte instruction cache. The difference between B1955 & B1965. Well you've all seen how BIG the B1955 was. The B1965 with soft console (which I LOVED working on...) is about the size of a group of desk drawers on a standard desk! Maybe 2.5 feet tall, 20 inches wide, and 24 inches deep. (Real guess on that -but it was a VERY small box.) It was every bit as capable as the B19XX chassis. The Disc Controller was reimplemented as 5 cards using an 8086. There were two data com options, the single line and Multi-line controller. The Multi-line controller was the only "DMA" device in the system and was also a 8086 based design. The soft console was an 8080 implementation. All this stuff had to be field testable/repairable so the soft console designer (Dick Mogia) went to considerable effort in having two paths to do everything. If the UART was dead, he had some 8255 parallel port bits that he could bang out the serial code needed by the console to show the problem through independent transistor drivers if the RS422 drivers were dead! It also controlled the the tape drive used by the system to IPL - the UART did double duty here. With the addition of the UART and a uP driving it, we found out just how bad the tape drives REALLY were. Up until then it was done with a state machine! There were really BAD parity error and tape errors that occured. The tape didn't last long! We had the same kind of issues as the B80's floppy! This was all revealed when we had something on there that could categorize the types of errors we were seeing! I had ALOT of fun working on the machine, and learned alot too! Steve Wilson

DECmate III with a serial console?

by dbetz＠xlisper.mv.com

Well, I had four DECmate III computers when I went to VCF East and now I'm left with only two. Unfortunately, I don't have keyboards or monitors for either and that makes them unusable. Rather than trying to acquire a keyboard and monitor I'm wondering if anyone has tried to replace the boot ROMs to allow either OS/8 or OS/278 to boot using a serial terminal connected to the serial port. Is that even possible? It would be nice to be able to use these machines without a monitor or keyboard. Thanks, David Betz

Register your exhibit for VCF 7.0!

by vcf＠siconic.com

It's time to register as an exhibitor for VCF 7.0! The dates have been changed from October 30-31 to October 2-3. I wanted to have a Halloween VCF, but it wouldn't work out for too many people, so that idea unfortunately had to be scrapped (though you're still welcome to come dressed up if you'd like). This is less than 3 months away, so get your exhibit figured out and register ASAP! http://www.vintage.org/2004/main/exhibit.php The exhibit categories are going to be re-vamped this year, and all registered exhibitors will receive an update once the new rules and regulations are posted (in another 2 weeks or so). In the meantime, select an appropriate class from the existing ones. Please e-mail me directly if you have any questions. I hope to see at least 50 exhibitors at VCF 7.0 so please sign up!! -- Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org [ Old computing resources for business || Buy/Sell/Trade Vintage Computers ] [ and academia at www.VintageTech.com || at http://marketplace.vintage.org ]

CADAC Motherboard

by marvin＠rain.org

Is anyone familiar with the CADAC Motherboard? I couldn't find any information using Google. It looks like it might be an Apple clone with one slot for the ROM board, and 7 slots for other cards. There is an RCA video output as well as two 1/8" jacks labeled "IN" and "OUT". It has both a Z-80 and a 6502 microprocessor.

Amigas strike back!

by huw.davies＠kerberos.davies.net.au

I was watching the test match from the UK on my local cable provider (Optus) earlier this evening when suddenly the screen went black (loss of sync) to be replaced with an Amiga desktop (in black and white). Looked like a much later release than the version I ran about 15 years ago but still recognizable. I wonder if this was a local Amiga or perhaps (more likely) a desktop in the UK.

B700 vs B1700

by aek＠spies.com

Indeed, I worked on the development of the B80 and the 8 in floppy was the system disk for some configurations. It held 1 M byte -- Was there any common code developed between the 700 and 1700 series? One of the things I had wondered about was on the front panel of the 1700 the '1' in 1700 was smaller than the rest of the digits, like it was somehow related to the 700, which seems strange since they aren't at all alike archetecturally. I'll have some more info on the 700 series going up soon. May be of use if they ever try to get the B800 running again (though I'm not sure if they got any software with it)

VCF East 2.0 report...

by wh.sudbrink＠verizon.net

Take two days off work and it takes a week to recover... Anyway, here is a brief summary of my experience of VCF East 2.0. For those that want to look at some pictures (quality not guaranteed, my camera sucks) with no captions or anything: http://wsudbrink.dyndns.org:8080/vcfe2004/ Thursday, 7/15 Left Washington, DC at 6:20am. The drive was uneventful but long. Ten hours including gas and lunch stops. Couldn't find any other VCF'rs right away, so I settled into my room, posted to classiccmp and surfed a bit. The in room high speed internet at the hotel was nice, easy to set up and well firewalled. Later, went back out to my car for a couple of things and saw Hans Franke in the lobby. He had some stuff to do, so we agreed to meet in the hotel bar later. I drove over to recon the Sun site. Getting there was as easy as it looked on the map and the visitor parking was right next to the main entrance which included a ramp. Met Hans at the bar and after a little while, Lawrence Wilkinson joined us. Learned that Sellam was on his way from Japan and would be arriving the following morning. Suggested new classiccmp motto: "Collect vintage computers and see the world!" Had a beer (Thanks Hans!) some pleasant conversation and called it a night. Friday Arrived at Sun around 8am. I wasn't the first one there. Curt Vendel and Evan Koblentz were already there and several others arrived soon after. There was some waiting around while the Sun employees figured out what needed to be done, then we were registered with Sun security and started setting up. The area for the exhibits was a nice atrium adjacent to the employee cafeteria. I started setting up my machines, fully expecting the OSI to be a pain, due to the less than reliable "fatherboard" bus system it uses. It surprised me however, coming right up on the first try. I should have suspected something right then! I finished getting set up and started wandering around taking pictures, waiting for the speakers to start. After about an hour, I noticed that the display on the OSI had gone blank. "Ha! Got me after all, didn't you, you silly box?" So I broke out the toolbox, expecting to have to reseat the cards. A little thought went through the back of my mind that usually, when its bus is compromised, it displays garbage and I didn't remember it ever going blank before. A few people noticed me getting out my tools and wandered over to watch. As I picked it up to turn it over (you have to put the integrated keyboard style OSI boxes on their backs to work on them... great engineering) an embarrassing rattling was heard by all, eliciting a chorus of "Hey, you've got something loose in there!". Now I knew that there was nothing loose in that box when I brought it in >from the car and there are no moving parts in it other than the fan, which had been humming along just fine when I powered it down, so what gives? I proceeded to open the case and there were two button style diodes loose in there. A quick look around showed that they came from the power supply and seem to have simply dropped off their leads. They must have heated up to the point that they melted the solder and fell. Well, nothing to do for it but put them back. Another testimony to OSI design is that you have to pretty much completely disassemble the box to get the PS out. Part of the PS frame supports the fatherboard. Repairs killed the whole speaker time and extended into the actual exhibit time, but I was able to give my spiel and make conversation with the people looking at my exhibit. Got it all up and working again and those diodes heated right up. I reached in with a toothpick and the solder was clearly molten so I powered it down and declared the OSI a non-functional exhibit, sigh. The rest of the exhibit time went well, with my Sol and Northstar both running like champs. The Sol running _Space_Raiders_ and the Northstar running _Zork_. We closed up for the day and a large group went to Victoria Station restaurant for dinner. It is a neat looking restaurant, with real train cars incorporated into the building. The food was good and I sat next to Art Hill and his wife and got a little bit of a preview of his Saturday talk. Saturday I attended all of the speaker sessions on Saturday. They were all great! Art Hill has had a remarkable career with computers, starting back in the tube days. He shared some of the experiences he has had along the way. Lawrence Wilkinson told us about bringing an IBM 360 back to life along with all of the logistics involved (like, where are you going to put it?). Evan Koblentz shared the results of his research into the history of PDAs, which goes back a good bit further than you might think. Finally, Jon Titus told us about the Mark-8, both in technical terms and about the process of getting it (the article) published. The exhibits were pretty well attended on Saturday. Several Sun employees came back and brought children with them which was fun. Showing them _Zork_ in particular... "Wow, you can have a game without pictures?" Things finished up. Oh yea, I won first place in "Manufactured personal computer - Pre 1981" and third place "Best of Show". Got everything packed up and went with Hans, Lawrence, Evan, Bob Maxwell and William Donzelli to Chili's for dinner. Hans would have preferred to go back to Victoria Station (with its large portions) but he made do by ordering two entrees! We got a call from Sellam and, after dinner, Hans and I went back to Sun and rescued a VCF sign that had been forgotten out by the entrance. Sunday Before the trip home, I went over to MIT for the swapfest. I got there at 7am, thinking that I would just pay the sellers fee to get in for a while before I hit the road. I discovered that, while it's not mentioned on their flyer, they do have a $15 "early bird" admission that gets you in at 7:15. No $1 discount on the early bird admission however. The $15 was worth it as I made a great find, a blue, 9 inch Ball monitor, manufactured in 1979, in great shape. For $10, an almost perfect match for my Sol, down to the PL59 cable that came with it! I found Hans at the swapfest and gave him the VCF sign (that had been left in my car the night before) and hit the road for home at about 9:15am. Thanks to everyone whose efforts went into this event! I had a really great time and will make every effort to attend next year. Bill Sudbrink

I have also found a couple of pdp11 peripherals handbooks, but none of them go into any real detail on the differences in memory and what is useable in which system. If you want, I can mail you the handbooks. Joe Heck

B1955

by stevew＠ka6s.com

Well - my wife says I can't bid on it :-( I helped bring the machine into manufacturing! (Hi Hans...) It was the first TTL machine Burroughs made, and is built out of basic 74S series stuff and proms. I joined the company as they were bringing up the etch card version of this machine. My first job was to get all the etch cards debugged. If anyone buys the beast here in San Jose - I would love to help get it working. Al has my notebook on the follow-up machine, the B1965 that was the basis for the Field service manual for the B1965. Some of the cards are common! P.S. Al - is the Computer History Museum ever going to be interested in resurecting the B1955 they have?? Steve Wilson

Hi, Does anyone have a copy of Pagemaker for the MAC (68k not PPC) which I can, ahem, borrow? I want to convert some documents that I have over to PS/PDF but I only have the PC version of Pagemaker and the documents were created on the MAC. They are only cross-platform compatible across the same version of Pagemaker :-( I believe the documents were either created in Pagemaker 3.0 or 4.0... Thanks, Ram

Connector question...

by dholland＠woh.rr.com

Hi, I'm getting around to doing something w/ that RS/6000 59H (finally) - Backup server for my network. So I Epay for a 10/100 MCA NIC, (No, 10Mbs won't do for the amounts of storage involved). I've had a Sun Storage Library in the basement for a while, get AIX re-installed, and the box on the LAN.. And then I go to plug the library into the SCSI connector. Wots this.. Hmm, not HD50 like I thought.. Hmmm Google..Google..Google... And an hour later Google has told me very little. Anyways, the SCSI card is a IBM's SCSI-2 Fast/Wide card # 71G2589. The connector itself has 68 'pins' (says so on the connector) Looks more like a Centronics connector but is smaller, and has more than 50 pins. (Or you could say it looks like a SCA connector, but is missing 12 pins.) Its also to "big" to be VHDCI. Hopefully I'll be able to re-ID the harddrives in the system, and connect the library onto the other end of the SCSI chain, and get it connected that ways. (Otherwise, I'll be looking at interfacing the library to a SGI Indy (or Octane). The RS/6000 is at least more impressive looking.) Anyways, I'm annoyed now, and would at least like to know what that connector is, and where I can get an adapter/cable for it. (whatever this is to HPDB50) Anyone out there own a "Mallet-O-Understanding", and feel like beating me about the head and shoulders w/ it? :-) Thanks, David

B1700 -> B1800 -> B1900 (B1000) It's cool because there wasn't a single macroinstruction set. The operating system and every language had its own pagable microcode. Was saying on nerdnite last monday that Burroughs managed to come up with some really interesting architectures for a really boring segment of the computer industry (banking)

PS William: still haven't forgotten your LINC-8 hulk, still interested in pursuing that, would like to come and have a look some time. PPS anyone reading this: my pdp-12 is missing one vital feature, the tall, narrow green door that covers the I/O terminals etc. Anyone by any miracle got a spare? And, sorry for missing VCF-East; I screwed-up my dates, we only got back from vacation in Scotland on Sunday. I had planned to get back the weekend *before* VCF. Corestore will be out in force next year! PPPS Al: are we missing any important pdp-12 software or docs for bitsavers?

Burroughs B1955

by aek＠spies.com

If people are curious about the details, I've been scanning a LOT of 19xx material lately. The 1955 was the last of the 1000 series to have a control panel with lights and switches, too (it is under the right front door in the main cpu cabinet) and has the classic panel layout of the earier models which were visible on the front. d

Hi Morgan. This is very unfortunate! The best thing to do is immediately transfer the wet documents to a freezer. This will effectively freeze-dry the documents and give you a chance to recover them. There have been numerous discussions on the Classic Computers mailing list about this in the past, and so I've copied this reply to that list. I would ask that anyone posting replies please also post a reply to Morgan directly (see his e-mail address in the header please).

Lost a radio at VCF East?

by vcf＠siconic.com

I'm missing a radio (walkie-talkie) and two wall warts that were at VCF East. I'm pretty sure they got stolen from my luggage by some fucker at either the TSA or JetBlue, but on the off-chance that I somehow left them behind and they did not get noticed, did someone else pick these up by accident? The radio is made by Maxon...all black, two channel. Just covering all my bases before I file a larceny report.

Burroughs B1955

by aek＠spies.com

It may have been a different model but it was the same vintage. I've got some 5.25" floppies from it if anyone cares or wants copies, I think it's most of the OS. - That would have been a B1965 or later with the 'soft' console, which replaced the front panel and cassettes. I'm VERY interested in any tapes, floppies or docs for these systems and if anyone turns up a B1965 CPU or later PLEASE contact me, as a friend of mine who designed the 1965 CPU would like to have one.

Burroughs B1955

by aw288＠osfn.org

There is a B1955 mainframe system on Ebay right now, with just about a day left: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&rd=1&item=5109222569 This is a circa 1980 system - it is sort of large. It looks complete, but it really is hard to tell. I really don't think I can go save* this beast, so I am passing this on. Anyone in the South (Louisiana, I think) interested? Old B machines are very rare, and very much worth saving (it has an interesting architecture, too!). Only if all of the moons line up will I bid on this, so if someone else is pretty sure they will move on it, please let me know. I would rather have a coordinated effort here. *The high bidder (at one buck) is a scrapper - check out the auctions he has won inthe past. William Donzelli aw288(a)osfn.org

printing pdf manuals

by jwest＠classiccmp.org

I recently got an upgrade for my Laserjet 4+ printer. It included a duplexer, 64mb ram upgrade, envelope feeder, and extended paper tray. I've printed off a few manuals on 3 hole punched paper from Al's bitsavers site and I've been really happy with the setup & results. However I have a question perhaps some here can answer... If one has a separate paper tray on their printer for, say... 11x17 (schematics), will adobe pdf reader software print all the pages on regular paper, and as it's going along, notice which pages in the PDF file are bigger (11x17, or legal, etc.) and print those pages "in-line" from the other paper tray? My thought is... after printing, I could take the stack of printout and fold in the long schematic pages before dropping it in a binder. I have no idea if adobe acrobat reader does this "sensing of paper size on each page" or not. Anyone have any thoughts on this? Lots of the manuals I want to print have fold-out schematics pages sprinkled throughout normal 8x11. If this cant be done, I was thinking I could print all pages except the big size ones (by looking at each page :\), then print those separately but thats a pain and I don't know if I can say to exclude certain pages. Thanks for any thoughts/advice! Jay West --- [This E-mail scanned for viruses by Declude Virus]

Xerox Sigma VII --- big IRON

by ghldbrd＠ccp.com

Just reminiscing over my first encounter with computers back in 1970 ----- It was a Xerox Sigma VII in the basement of the Montana State University. REAL batch programming, with stacks of punchcards, and a really crappy compiler that burped when it hit the first error. APL was done via dialup terminal and Teletype machine --- dial the number and plug in the handset (Ma Bell wouldn't allow direct connection of modems to their phonelines back then). Does anyone have a picture of said critter? I'd like to get one just for memory's sake. Sigma VII was a computer one loved to hate. Gary Hildebrand St. Joseph, MO

IBM RISC System/6000 58H available

by vcf＠siconic.com

I've got an IBM RISC System/6000 model 58H available for sale. According to the spec sheet on this page: http://www.s6000.com/modelpr.html ...it's a 55Mhz Power2 system with 32K I cache and 256K D cache (no, I don't know what any of this means). I don't want much for it. I'll be willing to ship it if you really want it that bad (it's not heavy but it is large). Make a reasonable offer and it's yours. Local pickup will get preference. -- Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org [ Old computing resources for business || Buy/Sell/Trade Vintage Computers ] [ and academia at www.VintageTech.com || at http://marketplace.vintage.org ]

This looks far too complex inside to be for a hobbiest. BTW :these don't seem to be too rare. I searched the net and found several for :sale but no one has any info on them. We're actually Bowe Bell and Howell, because of Bowe Systec AG merger. It seems that anything that's not document printing and mail inserting and handling (which is what BBH is known for) is all but forgotten about. I'll have to ask my boss about the old skool days.

IRIX 5.3 and 'configure' utility...

by julesrichardsonuk＠yahoo.co.uk

Ok, I'm starting to get a nice little Indy system together now :-) Any ideas where I can get the 'configure' utility from? (hopefully there's a version that can be made to work with 5.3). Not sure where it is, or if it's buried in some random collection of stuff. cheers, Jules

Commodore Pet ROM trouble... EPROM Substitutes...

by RMaxwell＠atlantissi.com

Oops. Error! Correction: The 2532 Vpp is always +5V when reading, and would keep 2732 outputs always OFF. The 2532 has just one enable pin, while the 2732 has two. Better to tie 2732-20 to ***2532-20*** (or to GND - outputs would be always enabled when the chip is selected). Sorry 'bout that. Best of luck, Bob
