warning about dealing with Government Liquidation

by Billy.Pettit＠wdc.com

William Maddox wrote: Some years ago, an old decomissioned Cobalt-60 radiation therapy machine that had been sold to a Mexican hospital ended up in a lot of scrap metal. The problem was detected when a truckload of "hot" steel rebar set off the radiation detectors when coming *into* one of the weapons labs. It turned out some of the metal had ended up in the cast-iron stands for restaurant tables (McDonald's, I think). I wonder how much of this radiactive metal was never located... --Bill ------------------------------------------- There was an old Nova special about a very similar case except that a lot children were playing with bits and pieces from the machine in the scrap yard. Several came down with radiation poisoning and/or leukemia. By time it was discovered there were dozens of people exposed to it. If I remember correctly, though it was Cesium 137 packaged in nice bright coloured packages, very attractive to children. Most of the material was never recovered. Billy

Simulated CP/M-68K?

by aek＠bitsavers.org

Someone on comp.os.cpm wanted to fiddle with the Alcyon C compiler and asked if there is a simulation of CP/M-68K running under Unix. After a bit of digging, I couldn't find one, which was surprising. Does one exist? There are a few simulated 68K systems in MESS, but none of them ran CP/M. It looks like a SAGE II simulation could be added since the software and docs appear to be out there (doesn't look like the SAGE IV boot prom has been dumped)

You apparently already have the image, so get cdrecord, available for Unix and Windows. I do find myself wondering how you created the disk image in the first place, and if it's actually usable; you can't just copy a ODS-2 hard disk block-for-block onto a CD and end up with anything usable. Why not just get yourself a copy of the Hobbyist CD and avoid the pantomime? -Rick

I have heard of success using BurnAtOnce. It seems to be free and is based around known-good UNIX tools (runs on Windows), and so it should handle odd filesystems just fine (you may need to rename your image >from .odsimg or whatever you call it to .iso for the burning run).

VCF East 4 was nostalgia writ large. Chuck Peddle entertained all. A true pioneer. And other presenters - collecting and CP/M history -> warmed the cockels of my heart; the historian in me. Kudos to all who put VCF East 4 on -> a computer faire that celebrates old computers. May they never die. [ Have to add this.

networked games 1972 to 1988

by akb+lists.cctech＠imap1.mirror.to

Hi all-- I'm doing some work on promoting Netrek, and it's gotton me interested in the following qualities: graphical (incl. ascii graphics) action (real-time-ish) multiplayer, by which I mean 3 or more wide area on the internet teams leagues and guilds If anyone can help with the following questions or add material, that'd be great... I've got the following timeline points: 1972 - Alto Trek probably first networked game multiplayer 1973 (Fall) - Empire II on the PLATO system not networked, but a wide-area multiplayer action game from graphic terminals did not clock like a modern game; players called for their own screen updates manually 1974 - MazeWar, probably second networked game ? XNS/PUP, right? first First Person Shooter first use of Avatars (enemy players appeared as walking eyeballs. I don't count ships as Avatars) first level mapping first or second rendered 3D perspective graphics (Spasim may have been first on this) ? In 1993, SGI did a Mazewar demo at Interop, with workstations placed around the show, So at some point, MazeWar became playable on a routed TCP/IP network. When? 1981 - Empire tournament play starts 1983 Jan - flag day; NCP turned off, net goes TCP/IP 1983 - SGI Dogfight (aka fight) ? I think the first game with its own Internet client-server protocol? ? Did Mazewar get there first? It was client-server and not peer- to-peer, right? ? I also think it was LAN-only, using broadcast UDP? I've also heard it was originally XNS, but there's a well-known UDP port for it, so when did it switch? I believe that while it was possible to choose to play in ? cooperation, the game itself did not have teams per se? 1985 - X Window System 10 ships 1986 - Xtrek, descendant of PLATO Empire ? first X-Windows thrown-display game? 1988 - Xtrek II: Netrek ? second client-server game? ? first client-server team game? ? first client-server game with routeable protocol? 1991 - Netrek league play starts So, what am I missing? 1974 to 1983 seems like too long a gap for there to have been no ARPAnet graphic action games... there were many PLATO games during that timeframe, and an IBM space battle game of some sort. Also probably military simulators. Thanks all!

The longer answer is that an ISO image isn't really the right term as it is an ODS-2 or ODS-5 format disk, but most people will understand what you're asking. I recently created a logical disk on my VMS system, copied data to it, and then FTP'd it to my Mac where I burned it to CD and was able to access it on my VMS box. I'm not sure if you're asking about being able to burn CD's on VMS, but that is also possible, at least on Alpha and Itanium, and I believe that as of 8.3 it is part of the OS. I've not done this, as it would be more trouble to set this up than to simply FTP the file to my Mac. :^) Zane

The rest of the board (glass fibre) is bare, so no power rails etc, so you have to drill and fit sockets or components and wire-wrap them together. Please mention 'classiccmp' when replying.

Strange VT50 Decscope

by RodSmallwood＠mail.ediconsulting.co.uk

Having racked my ancient brain I think the white one might have been a "Burn in test model". DEC used to rate reliability on terminals as "XXXX Hours MTBF YY% Confidence factor". To establish a baseline they would take several hundred terminals and run them noting the failures. What this meant was that if you burned in terminals for XXXX Hours in test then you could estimate the in service MTBF to a confidence level of YY%. This was also used to estimate field service spares requirements. If the actual failure rate differed then they would alter the burn in time on the production testing. As the test models were never intended for sale they never bothered to get them silk screened. What do with a lot of unsaleable VDU's? Answer give them to your employees. Rod Smallwood DEC Terminals Product Line 1973. -----Original Message----- From: cctech-bounces at classiccmp.org [mailto:cctech-bounces at classiccmp.org] On Behalf Of Ashley Carder Sent: 12 June 2007 14:57 To: cctalk at classiccmp.org Cc: wacarder at usit.net Subject: Strange VT50 Decscope A couple of months ago I acquired a strange looking terminal that was said to be a VT50 Decscope. A picture of it can be found on my web site at: http://www.woffordwitch.com/VT50.asp The case looks like it was cast in pieces from a rough mold of a standard VT50. Many of the key caps are not the usual color, and look more like the key caps on the earlier VT05. I have not opened it up and studied the inside yet to see if it has the proper "guts" of a VT50. The previous owner said that he worked for DEC back in the 1970s, and they gave this "VT50" to him to use at home so that he could remotely connect to a system at work. Are there any former DEC employees (or anyone else) here who have ever seen or heard of anything like this? Thanks, Ashley Carder http://www.woffordwitch.com

classic computer rescue squad

Hi-- I'm seeing posts here about systems to be rescued, but often no replies. The classic computer rescue squad pages have no listings later than 2005. This is a high-bandwidth list that people interested in old systems can't neccessarily keep up with. Could we get a seperate list going just for rescue listings, and have either cctech or cctalk as a subscriber? That way, folks interested only in seeing systems listings could see them and maybe rescue systems. Thoughts? --akb

dream on: equip in NORAD bunker in North Bay, Ont

by hilpert＠cs.ubc.ca

Last night on the CBC TV news there was an item about a decommissioned underground NORAD bunker in North Bay, Ont. and how the Cdn gov/DoD is trying to figure out what to do with it. The control room is still filled with equipment, including SAGE-style-or-era video consoles (not sure that they were SAGE, the camera went by too quickly). There was also a camera shot of what appeared to be some other desk-style computer console. The reporter referred to the place as being 'filled with obsolete equipment', the rest of the systems are presumably still there too. .. now that would be a rescue .. one can dream, but it'll probably all end up in the scrap bins. Perhaps somebody nearby should start making inquiries. Does anybody with a background in SAGE know whether that bunker was part of SAGE, or what systems would be in there? I've never been really clear on how the SAGE / DEW line / other NORAD systems related to each other or overlapped/interconnected in operations or equipment.

Nanocomputer Training System

by steven.hatch＠hp.com

Hi, I just read your note that you just got a NBZ80 Nanocomputer. Where did you get it and how can I get one? I will give you a really good hint about what you can do about documentation. I have two books that are based entirely upon that nanocomputer. Here are the titles of those books. Actually it is Book 1 and Book 2. Name: Z-80 Microprocessor Programming and Interfacing. Authors: Elizabeth A. NIchols, Joseph C. NIchols, and Peter R. Rony Go to www.abebooks.com This is a used bookstore and they have thousands and thousands of new, used and out of print books. I know that they have some listings of these books. I had Book 2, but just got Book 1 from them. good luck. If you know where I can get another nanocomputer, I would appreciate it. steve hatch

PDP11/10 looking for a home

I have received request/permission from Richard Krasnow to post the following request ----------------------------- Hello, I have a PDP11/10 that was working fine the last time it was turned on, back in 1984 or so.

Strange VT50 Decscope

by wacarder＠earthlink.net

A couple of months ago I acquired a strange looking terminal that was said to be a VT50 Decscope. A picture of it can be found on my web site at: http://www.woffordwitch.com/VT50.asp The case looks like it was cast in pieces from a rough mold of a standard VT50. Many of the key caps are not the usual color, and look more like the key caps on the earlier VT05. I have not opened it up and studied the inside yet to see if it has the proper "guts" of a VT50. The previous owner said that he worked for DEC back in the 1970s, and they gave this "VT50" to him to use at home so that he could remotely connect to a system at work. Are there any former DEC employees (or anyone else) here who have ever seen or heard of anything like this? Thanks, Ashley Carder http://www.woffordwitch.com

My sale or swap list (Update)

by RodSmallwood＠mail.ediconsulting.co.uk

Hi We have friends in the mid west (Mason City). They also seem to cover vast distances to get anywhere at all. From their description of the weather, the favored modes of transport are stagecoach in the summer and dog team in the winter. Railroads are apparently ok so long as there are no Indian raids! (sorry about that!). I think the lake ports shut in winter. My rule of thumb used to be if I can't lift it its not airfreight! Its not like the old days at DEC. If you wanted to send something (anything) to DEC Maynard say. You put it in the car took it down to the DEC shipping section at London Heathrow. They would find a box, pack it, label it up and that would be that until next morning when they would ring you to say your package had arrived at Logan and would be by the addresses desk when he got into work. (Around midday UK time). The same thing worked in reverse. One day I asked the shipping manager how things did not get held up in customs. He said "Digital is the largest employer in Massachusetts and a major contributor to the state economy" That reminds me of another story. One day they ran out of parking space at the Mill. So they decided to fill in part of the mill pond to make more space. The Maynard town council said "Heritage site no you can't" Ken Olsen said "don't worry guys I'll call the Mayor". The Mayor said "Heritage site no you can't" Ken said "ok Mr Mayor if you look out of your window in about two hours you will see the first of the moving trucks relocating every DEC site in the town elsewhere. The Mayor said "OK if you look out of your window in one hours time you will see a fleet of council trucks loaded with dirt coming to fill the pond in for you!" -----Original Message----- From: cctech-bounces at classiccmp.org [mailto:cctech-bounces at classiccmp.org] On Behalf Of Ethan Dicks Sent: 12 June 2007 13:33 To: General Discussion: On-Topic and Off-Topic Posts Subject: Re: My sale or swap list (Update) On 6/12/07, Rod Smallwood <RodSmallwood at mail.ediconsulting.co.uk> wrote: > > 'has 1 cubic meter of volume and the first 1000 kilos' > That seems to be a lot of weight in a small space.

Indeed. Being in the mid-west, we don't think about ports much. I can drive to NYC in under 14 hours. Boston is farther. I think the closest Atlantic port, drive time, would be Baltimore at around, IIRC, 9 hours. Lake Erie ports are close (2ish hours), but would almost certainly require a shifting of the load to another vessel at an Atlantic port somewhere. -ethan

DEC CD Drives

by RodSmallwood＠mail.ediconsulting.co.uk

Hi I managed to locate an RRD42-AA (ie real Dec for 14 Pounds UK (27 Dollars US)) I aready have a Yamaha SCSI drive in an external powered case. I also managed to locate the correct cable. (50 Way Centronics male to 50 way D type male double density pins and clip type) This fits the SCSI connector on the back of the external box and the other (big) end goes into the KZQSA So... When the cable arrives try the Yamaha drive. If its no good. Then remove the Yamaha drive from its box and replace with the RRD42. This way I end up with one or maybe two working SCSI drives.

Dry Air Purging on IBM Computers

by marvin＠west.net

I was reading an application note about a Puregas heatless dryer, and one of the applications mentioned that some IBM computers require a dry air purge. Does anyone know which computer(s) this is referring to? The URL of the booklet is http://puregas.com/industrial/pdf/Drying_Compressed_Air_Booklet.pdf These things look like they could be useful when small CFM ratings of dry air are required.

DDC Fixed Head Disks

by jam＠magic.com

> I do recall some computer equipment that had helium in the enclosure. At least > that's what the labels said. I have a DDC 7301 drive (same manufacturer as Guy's, but different model), and it is definitely filled with helium. Well, it was filled with helium 30 years ago ... The DDC maintenance manual says it requires oil-free 99.995% pure helium. The preventive maintenance procedure indicates that the helium tank is good for about 6 months (dropping from 2200psi to 300psi). James Markevitch

There's something just, I don't know, wrong about the complaint that IRIX is a dead end on this list. Discontinued, yes, but so is DOMAIN, TSB, OS/8, CP/M ... and yet those machines are still collected/used/discussed here. At this point, VAX OpenVMS is at roughly the same position as IRIX- no new hardware and no major upgrades to VMS. IRIX will be "unofficially supported" by usergroups for quite a while yet-just look at Nekoware. They're still very well made machines, and IRIX has its quirks, but it is a good, stable UNIX implementation (and Indigo Magic is a pretty good UI). I suppose the collectors will get to them (SGI does have a reputation), but for now I'm happy that it's predominantly hobbyists- machines are cheaper that way. I haven't been able to afford a PDP-11, but I have several IRISes. Just think of yourself as being at the forefront.

DDC Fixed Head Disks

by ggs＠shiresoft.com

Hi, I just received a DDC (Digital Development Corporation) 6200X series fixed head disk. It includes all of the cables, power supplies and controller for a PDP-11. Before I hook it up to one of my 11's, does anyone have any docs on this beast? Here are the specs as I know them: Series: 6200X Speed: 3450rpm bits per track: 72000 access time: 8.7ms tracks: 64 unformatted capacity (MB): 0.58 Supposedly there was no scheduled preventive maintenance, however DDC made other fixed head drives that were helium filled and they needed periodic service. So, my question is do I need to do anything (like purge and refill) before I use it? Does anyone have any additional info? I did get some manuals with it, but they're mostly focused on the controller for the PDP-11. TIA. -- TTFN - Guy

See item # 120128637318 I won an SGI Personal Iris 4D/20 (1988!) workstation. I was the only bidder and I picked it up for $40. The cosmetic condition is excellent. Honestly, I expected someone to come in and snipe me at the last possible minute, so I increased my bid twice. The hard drive will be wipe, so I nee to get an OS package for this, which is probably as hard as finding the hardware. In several years of watching ebay for SGI gear, this is the first time I've seen a Personal Iris offered up, although I admit that I haven't had a specific search for it, so one or two may have slipped through the cracks.

DDC Fixed Head Disks

by Billy.Pettit＠wdc.com

dwight elvey wrote: The only two things I can think of where mentioned by others. One was thermal conductivity and the other was friction. Helium has almost zero friction. Still, the stuff leaks out of things so fast. Even solid surfaces. I find it funny that it is cheaper than argon. There is a lot of argon but I'd guess the extraction from natural gas, where it is undesired for burning, makes helium cheaper than argon that has to be intentionally removed from air. Two percent of air is argon as I recall. Dwight ------------------- Billy writes: Helium was used in a lot of early fixed disk and drum systems. There were several reasons for helium, but the main one is it gives good flying head support. Less dense than air, it allowed the heads to fly closer. It also offered less resistance than air, hence less power. And there was something about it having less boundary layer pressure at high speed, a good thing when you are trying to increase density. It was a bitch to seal in, so most systems sealed the entire assembly with only I/O cable connectors on the outside surface. I worked on a drum system using helium in the late 1960s and we had to change the cylinder about once a month. The cylinder was 20 cubic feet. One other application I heard of was for high altitude airborne systems. The air was too thin so a positive pressure system was used with helium. Since the application was military, not much was written about it. This was also the same application that used a micro drum (roughly 3 inches long, 1 inch in diameter.). Billy

LM309K regulator

by hilpert＠cs.ubc.ca

While conversing with another list member about some old components, I was reminded of hearing somewhere that there was a nasty failure mode of the LM309K 5V regulator (it being the (or one of the) first integrated 5V regs) which might make it somewhat undesirable for current use. I don't want to declare that there is such a problem - it's a vague second-hand rumour to me - so can anyone confirm or elaborate on this? I've never personally run across problems with them.. A 76 Moto databook indicates it has those nice things like short-circuit protection and thermal-overload protection.. ..another device perhaps?

VCF East 4.0 wrap-up

by evan＠snarc.net

Hola, collectors! I just got home from VCF East 4.0 of course I?m biased, but what a great weekend! Around ? of the exhibitors came Friday night afternoon/evening to get ready. This year we expanded the venue from one room to two. But, the second room is still VERY under construction. Some of our volunteers were literally still installing sheetrock that morning. So we had to use some yellow caution tape, but it added character. :-) Friday night was bar trip #1 I drove back to my hotel safely was but very, very tired waking up early Saturday. For Chuck Peddle?s videocon Saturday morning, the weakest part of our internet connection was the wifi or so I thought! Turns out, the wifi worked great, as did Skype. Chuck spoke to us for an hour+ then he got an strong round of applause then we were about to begin audience Q&A. All was fine until that part. Until our videocon server went BSOD!! We couldn?t even get it to reboot in ?safe mode? so we emailed Chuck from my cell phone, who said he had to get going anyway, but that anyone with questions could email him. Okay then! Bil Herb, Bob, Russell, and Dave Haynie took their turns next; lots more great stories and they brought many prototypes to show us, including the famous Commodore LCD. They even hung around out exhibit hall after the panel and after some chocolate chickenhead cake. One of them, Haynie, joined us for the official VCF Dinner that night. Speaking of dinner: the bill was $555.58. If only someone hadn?t drank that last three cents of beer ! Today was just as much fun. We had how-to lectures, we learned the history of CPM, we heard all about Jeri E.?s toy-making experiences and there?s a picture of someone posing next to our museum?s chip collection. Meanwhile the collecting guru Sellam told some secrets which I?m not going to share here except for this one: when pushing an 8-foot-tall rack, be alert for unstable monitors on top. (Hopefully there won?t be a scar.) My LEAST favorite part of any VCF is tearing down at the end of the weekend. But it had to be done. To ease out of the weekend while keeping out good mood, I went to dinner with Hans and Sellam, had a few beers, and well it?s been a while since I drank three nights in a row. Anyway, the show was terrific. Peddle?s unique hour-long lecture, 20-ish exhibits, attendance in the triple figures, and we even gave a few museum tours. Heck, one guy came all the way from New Zealand. Pics and hopefully some video will be posted soon. Patrick: I now pass the baton to you!

Updates to my PDP-11 web site

by wacarder＠earthlink.net

Since my collection has changed in the past couple of years (acquired a good many new items, traded/sold some other items), I decided to update my "PDP-11 Collection" page. I've added lots of new pictures. Take a look if you like "DEC Porn", as Jay calls it. Ashley http://www.woffordwitch.com

Help on HP 82901 drive

by steerex＠mindspring.com

> Hello. > I have a partially defective HP 82901 drive. I don't know this drive by model number, but IIRC it's a daul 5.25" drive with an HPIB interface. I have an HP drive that fits that description, unfortunately I can't get to it quickly, so I can't verify the model number, but I do remember some things about it. Can you post a picture of the controller card somewhere? I may have a spare one laying around here (somewhere). SteveRob

Anyone know the rotation speed of this FDD?

by pludikar＠sympatico.ca

> Go to http://www.hpmuseum.net/ and follow the links for disks and then > the 9114. On the 'product documentation' page you'll find 'my' schematics > for the 9114V. That includes the drive itself. Tony, many thanks - the schematics/circuit diagrams appear to be 100% relevant to my board. I can now start trying to figure out what I zapped. It looks like the -50 and -30 suffixes are little more than cosmetic changes or switch configurations. My FDD is also a half height. I was thinking about the Z0765A FDC and how to make it compatible with a 300rpm FDD. It seems that all that needs to be done (in theory) is to reduce all the FDC clocks by half - the 8MHz clock to 4MHz and the Write Clock to 500KHz. (NEC indicates this in their uPD 765A datasheet). Clearly not as simple to execute as it sounds, but not beyond the realms of possibility. Thanks to everyone else who responded. Peter

PI 4D/20 (WAS: Re: you *can* get a good deal on ebay)

by compoobah＠valleyimplants.com

Nice beast, a bit slow but decent, especially with the Super Turbo option. In talks with other hobbyists (and experience with my 4D/25 Super Turbo), it seems like the Turbo option is a bit delicate, so you might need to remove the turbo card and plug the RE1/RE2 into the slot (if it is a 1988 model, then Turbo wasn't offered and won't be an issue). The symptoms are graphics lockups. I haven't had time to look at my card and se what's up. It will run "IRIX" 4D1-3.2 through IRIX 5.3 just fine, note that to install from a CD-ROM you need to have a SGI-firmware CD-ROM (there is a hack in the firmware that has the drive identify itself to the SGI PROM as a fixed SCSI disk long enough to trick the PROM into booting >from it), and you'll need to ignore the "install system software" menu option and instead go into the PROM monitor, run "boot -f dksc(0,<CD-ROM device ID>, 8)sash.IP6" and then at the sash prompt type "install". IRIX 4.0 and above deal with CD-ROMs just fine, can't remember about 4D1-3.x. For 5.3 you will want 32MB or more, look on the old "SGI FAQ" for information on the endearing features of the PI 4D/2x memory controller.

Local (NY) PDP guy needed

by rcini＠optonline.net

All: I got an unusual phone call this evening from a doctor on Long Island who is doing theoretical biological research that, he hopes, will have a commercial application. Without going into much detail (because it was like drinking from a fire hose and I can?t remember it all), basically he is looking to emulate some biological processes in software. He believes that the ?instructions? that code for the biological processes are based on 6-bit instructions (or multiples thereof), so he?s looking for someone with that kind of architectural background. A PDP-8 has 12-bit instructions and I think the PDP-9 and 15 used 18-bit words. I?m not knowledgeable about any of the other minicomputer architectures to guess word size, but anything that?s a low multiple of 6-bits should work for his purposes. If anyone?s willing to have a conversation with this person, please contact me off list and I?ll pass on his contact information. Thanks.

wang 2200vp available, Vicksburg, MS, USA

by frustum＠pacbell.net

I was contacted a month or so ago by a gentleman with a wang 2200vp system that he would like to find a home for. I don't need another one, and I offered to "advertise" it here, but then it slipped my mind (it can be quite slippery sometimes). Many years ago in my business I had 2200VP set up complete with a Model 2260 disk drive. I think I had a Wang PC or two also. Since then, the components & the manuals (also floppies & disk cartridges) have been in storage in my attic (well, not the disk drive - whew! -- it is in a corner of my enclosed garage). Do you know anyone that might want any of this? I see nothing on ebay. I'm about ready to haul it all to the dump. Sigh. In a later exchange he said: I'm at Vicksburg, MS, right close to the Mississippi river. Yes, please spread the word that I want to move this Wang system out of my attic (and make room for other junk! ), The $12,000 5 meg (each platter?) disk drive I really think will have to go to the dump. I did not see any mention of it on the web and I doubt that anyone could use it. Have you ever seen the platters offered on ebay? I was thinking of trying that. I'm sure he doesn't want his email address in the archives, so please email me and I'll forward on his email address to you. You can learn more about the wang 2200 from my web site: http://www.wang2200.org

Anyone know the rotation speed of this FDD?

by pludikar＠sympatico.ca

Hi, I have a Sony MP-F52W-30 floppy disk drive, which I need to replace - it semi worked until recently (would read but not write) until I zapped it by accident. It comes from an HP 1650B logic analyzer - does anyone know if it's a 600rpm or a standard 300rpm device? If it's a 600rpm then I've found someone who has one but wants a lot for it, otherwise I'm reasonably sure I can modify the cable connections to use a standard/modern drive. On the motherboard side, it has a Zilog Z0765A FDC, and I've successfully created disks on my PC (using HP's LIFUTIL) that worked on the drive. This makes me think that the drive is a standard 300rpm. Any thoughts? Curiously the serial number label indicates the drive as a MFD-52W-10, while the bigger label on the bottom of the unit shows MP-F52W-30. I guess that the MFD is a base which is then modified to HP's specs (MP-F). BTW Does anyone know what the -10, -30 suffixes mean? I've also seen -00D and -01D around as well. Thanks in advance Peter

Databooks: keep or toss?

by RodSmallwood＠mail.ediconsulting.co.uk

Hi I remember about 1971 collecting a PDP-8 I was going to use to use for control/data capture on a experiment at Harwell. It struck me then why supply such cheap manuals with a multi thousand dollar well built computer system? It was obvious that the books would fall apart if used. I had our repographics people take the books apart, blow them up to A4 and loose leaf bind them. They used research report archive paper (rot proof, fire resistant and good for 100+ years) and as a back up microfiched them as well.

Databooks: keep or toss?

I have 25 linear feet of old databooks. I've kept them partly out of sentimentality and partly because I have to fix stuff of that era now and then. The data sheet archives I've seen on the web are woefully incomplete. Does anyone know of anyone/anything that collects these?

TESTFDC usage

by dm561＠torfree.net

--------Original Message: Date: Wed, 6 Jun 2007 08:34:37 -0500 From: "Dave Dunfield" <dave06a at dunfield.com> Subject: Re: TESTFDC usage <snip> To completely test the FDC, you need to check Single, Double and Double/128 at each of 250, 300 and 500 kbps rates. These are represented in a standard PC at: 250 = 5.25 low-density drive only, 3.5" low-density diskette 300 = 5.25 Low-density diskette in high-density drive 500 = 5.25" or 2.5" high-density diskette So to check all possible data rates without a 300/360 modded drive, you need to run two tests - either the 5.25" LD and HD drives, or a 5.25" HD and 3.5" drive. ---------------------- I also wanted to do some testing but, despite our off-list correspondence, I'm still confused: 5.25" drive, 3.5" diskette ??? 2.5" diskette ??? 3.5" drive - LD or HD? Exactly what tests should be run with what size/density disk in what size/ density/speed drive in order to get a complete picture? mike

TESTFDC usage

by arcarlini＠iee.org

I've been checking through the stuff I have around here and I've decided that I have a few surplus PC mobos that I'll be getting rid of (via a certain auction site). Before I do I thought I'd try them out with TESTFDC and see what it says. I have three 5.25" drives (of currently unknown functionality) which I could use. One is a DEC RX33, one is a Tandon TM75-8 and the last one is a Sankyo (or that might just be the motor manufacturer :-)). I also have whatever is sitting in my main machine, but I'm not keen to drag that out just foir fun! I also have a few 1.44MB 3.5" drives, but they've not been used in quite some time, so heaven knows what state they are in. So what do I need to do to extract the maximum useful information about these motherboards (aside, that is, from checking that they are not already on the list :-))? And exactly what media will I need? Should I test both 3.5" and 5.25" (I've not tried the 300/360 mod yet; I may do in the future, but for now I'd just like to get some testing done)? Anything to watch out for? Any particular version of DOS recommended (I have 6.2? kicking around, would FreeDOS do if that is easier to find)? Thanks Antonio

Anyone know anything about old TEC Terminals?

by classiccmp＠memory-alpha.org.uk

Hi, > Well, I don't know whether they're "plasma/LCD" or not, but I >find I get dramatically better picture quality out of flat-screens >as compared to CRTs. Well, the last two CRTs I bought are flat-screen so I'm not sure exactly what you're getting at. The biggest problems with LCD panels are colour registration, black level/contrast and response time. Even with top of the range panels, their comparatively slow response time leads to very noticable blurring when things move around on the screen - and I'm not talking about games here, I find this blurring totally unacceptable even when scrolling text windows, etc. And the colour/contrast/black level problems are a total show stopper when I'm dealing with video.... > I don't know whether this just means every CRT I've used has been crap, >or perhaps I *am* "profoundly blind", but even if so, in my experience >the comparison stands. I wouldn't have thought so, IME even the cheapest/crappest CRT is head and shoulders above even the most expensive LCD panel. It all depends what your expectations are.... TTFN - Pete.

I'm not sure > why - > maybe it's more resistant to absorbing moisture from the air or > something. > Moisture is a problem only if it's really high (mold predominantly, although sizing can soften and stick pages together). The big problem with many paperbacks is the so-called "high acid" paper with appreciable quantities of lignin in it - the lignin changes into acid and causes the paper to self-destruct. Think yellowing, crumbling paperbacks... I'm not sure what the paper of choice for databooks is, generally if a book uses sized bond paper it's not at highest risk, but for the most part wood paper made before the '80s will have some degree of risk (and more modern papers that are not acid-free archival grade). LOC (Library of Congress) has a fairly large group devoted to this problem, and a process fior neutralization that works pretty well (although if you do it wrong or make a mistake stuff bursts into flame). They point out that it is "not recommended for those who are not professionals".

Hi, >....hard to get new CRT monitors now and the cheap LCD ones are >rubbish! Cheap nothing, I've never seen *ANY* LCD monitor (either fabulously expensive or dirt cheap) which I would describe as being anything other than diabolical! The same goes for LCD TVs too - and plasma sets aren't much better in my opinion. The people who buy these things must be profoundly blind if they're satisfied with the picture quality produced by the current generations of plasma/LCD screens, the technology simply isn't anywhere near good enough yet. >....We'll soon be reduced to scouring eBay for real monitors :-) Quite, which is why I recently spend several months tracking down a very nice, 32" wide screen *CRT* TV set; which I got for next to nothing since the market is currently flooded with this LCD rubbish. :-) TTFN - Pete.

DECnet on the 'net

> I seem to remember that there was a group of people bridging their > DECnet over TCP to connect various sites over the Internet. I can't > seem to find them this minute. It's called HECnet (don't blame me - I didn't think of that name :-) We've got several dozen machines at a dozen or so locations around the world connected, and we're happy to have more join. To connect, you'll need either - A VAX running OVMS and Multinet (they have a hobbyist license, and also a DECnet-over-IP implementation). If you have multiple local DECnet machines and your VAX is a DECnet router, then they can all play with this one gateway. Or - A Un*x box of some variety running Johnny's DECNet bridge program. In this case the Un*x box is in addition to whatever other DECnet machines you have on your local network. You'll also need an Internet connection (of course), and a _static_ IP. Contact me off the list if you're interested in connecting and I'll point you in the right direction. Bob Armstrong

DEC H775-BA and H3213-3400 in Kansas

by wulfcub＠gmail.com

While cleaning out a storage area (indoors), I found an H3213-3400 psu and an H775-BA remote battery backup unit. As I recall, these both came out of a Xerox 9700 controller cabinet, and the H3213 worked when we last fired it up. The BBU hasn't had a battery pack on it in at least 11 years (as long as I've been with the company), so I have no idea whether or not it works. They're both free for the taking. Pick them up, or arrange to have them shipped. Both are fairly heavy and the 3213 is rather large. Located in Wichita, Ks. May trade for C= 128 gear.

DEC parts code reference?

Out of interest (and to my shame, without googling first :-), did DEC (or a third party) ever produce a reference listing of DEC "parts codes" against function (e.g. RK05 = removable disk, KL11 = serial interface etc.) I'm trying to sort out our documentation archives, and DEC seem very good at just listing the codes as title ("DZ11-C technical manual" etc.) on a lot of their docs - meaning I have to skim pages to get a handle on what the thing actually is) cheers Jules

That's a copy of stuff rescued from Decwrl after Compaq took over. I'd almost forgotten all the time spent in Runoff. I'd used to say that I produced the last implementation of DECnet Phase IV in PathWORKS for Windows 95. But these guys doing the Linux DECnet have taken that away from me. http://linux-decnet.sourceforge.net/ If you're interested in learning how DECnet works, that implementation is freely accessible. PS: There is a Debian MOP daemon here http://packages.debian.org/unstable/net/mopd I seem to remember that there was a group of people bridging their DECnet over TCP to connect various sites over the Internet. I can't seem to find them this minute. Dave.

More Seattle Spring Cleaning - HP 7980A / M4 9914 9-track tape drives

by glen.slick＠gmail.com

Anyone in the Seattle area looking for a 9-track tape drive project? I have one HP 7980A HPIB and two M4 9914 SCSI/Pertec drives. These are front loading / auto loading units. Unfortunately they need some work to be fully functional. The problem with both M4 units may be limited to the tach rollers not accurately rolling along with the tape motion. I had one of the M4 units working briefly a couple of months ago. If anyone local wants these let me know with a private reply. These are too big and heavy to deal with shipping. -Glen

Apple II

by swtpc6800＠comcast.net

There are various news stories about the 30th anniversary of the Apple II computer. My favorite story is that I had Apple II serial number 2 for evaluation. At the time I was working at a computer store in San Mateo, California. The owner, Chet Harris, when down to the Apple factory one Saturday in June of 1977 and came back with the first two completed units. (This must have been June 4.) He had sold serial number 1 to a friend of his and I got serial number 2. After a few weeks the power supply failed and it was sent back to Apple. Jef Raskin ended up with this unit. You can read about it here: http://www.swtpc.com/mholley/Apple/allied_computer.htm Apple started selling the Apple II boards around April of 1977. They were having problems with the plastic case, the early production units did not have the vents on the side. You can see that in the picture of serial number 2. http://www.swtpc.com/mholley/Apple/Jef_Raskin_Apple.jpg A customer at the store, Bill Kelly, was doing the advertising campaign for Apple and he got a prototype Apple II board. I built a linear power supply for it and traded it to him for an Intel SDK-80 board. Here is his web site: http://www.kelleyad.com/Histry.htm Here is a page that shows the my SDK-80 board. http://www.swtpc.com/mholley/Homebrew/Homebrew.htm Even though I went to the Homebrew Computer club, looked at the Apple I, and I had use of a Apple II; I have never owned an Apple computer.
