The 3rd annual Vintage Computer Festival Southwest http://vintage.org/2012/southwest/ is this August 4th-5th. We will feature a tour of the Ross Perot collection http://mit-a.com/perotcollection.shtml of vintage computing, including several sections of the original ENIAC computer. ? We will also be adding a special tour of the Cowboy Stadium IT infrastructure. http://mit-a.com/CowboyStadiumTour.shtml The regular tour lasts an hour and a half - this one will run slightly longer. The group tours cost $20 and everyone says it is definitely worth it. We will need to have at least 15 or so people for this tour, and will need to sign up (and pay) in advance.? ? The VCF SW 3.0 will be at UT Arlington. http://www.uta.edu/uta/ More exhibitors, vendors, and speakers are registering frequently, so check the website. We are still looking for exhibitors, vendors, and volunteers (who get to attend free.) Gil -- A. G.

Microsoft licensing

by saquinn624＠aol.com

Richard writes: Wrong. As long as you have the certificate of authenticity for copies of MS-DOS, you can continue to ship product using that operating system. Medical device manufacturers are doing this because if they change the operating system, they have to requalify their devices which is a very expensive process. So they continue to buy NOS copies of MS-DOS, as long as they have the certificate of authenticity, and use those to ship their products. They will continue to do this as long as the cost of obtaining NOS MS-DOS product is less than the recertification process. Given the number of NOS copies still in the marketplace, they won't need to upgrade the OS for some time. There is a local guy who mostly deals in C=64 equipment that has been making quite a nice side business of finding NOS copies of MS-DOS for some time now. You would think so, wouldn't you, but as I said before Microsoft is being very creative. The software that you're talking about is unused, possibly retail or possibly OEM, but in any case the license has not been attached so it can be used on any device (for OEM, provided that the equipment is new). You would think that an OEM license, since it is attached permanently to the hardware, would transfer with the hardware, right? You would think that presenting the certificate of authenticity or other evidence that the hardware was licensed would be enough to show a license, right? Not so fast. A couple of years ago MS, upon a closer reading of the license agreement, noted the part that says that all copies must be transferred when the license transfers. Most people understood (and probably understand) this to mean that you can't keep any copies because there's only one license, but MS reinterpreted it to mean that if all copies are not transferred then it is not a valid license transfer and the license is invalidated, requiring a new license transfer. They set up a new "Refurbisher Program," whereby people selling used computers can give Microsoft more money to make sure nothing bad happens to their nice business. In an interesting twist, the now "meaningless" original "Certificate of Authenticity" must still be present, otherwise you need to cough up the full retail price should you want Windows - thus, per MS, the computer product the license is tied to is the mainboard (which cannot be replaced unless in cases of failure, when MS may choose to make an exemption if they really feel like it), the COA, and any manufacturer provided backup media, including the "recovery partition" of a disk which, if it is damaged, now appears to nuke your license for Windows. At this point they only seem to be targeting used computer stores selling machines with Windows, but until someone takes them to court and wins it could be anyone they want to squeeze. As noted, one copy of MS-DOS is probably not going to be a big deal, but MS appears to not be taking the "live and let live -after all we've already been paid" attitude and it might get worse. I found all of this out because of the good part of the program - MS will give really cheap upgrade licenses to qualifying nonprofits using used computers through the same program. Want to check it out? Search MS for "refurbisher program"

emulating /dev/nrmt

by spectre＠floodgap.com

Since I'm getting more into early 90s workstations (the workstations of my undergraduate years), I'm finding a need to emulate a network tape device for installs and restores. It seems like there should be such a tool already that can mimic /dev/nrmt (TMSCP?). Is there? Some cursory Googling didn't turn up anything obvious, unless I'm looking in the wrong place. -- ------------------------------------ personal: http://www.cameronkaiser.com/ -- Cameron Kaiser * Floodgap Systems * www.floodgap.com * ckaiser at floodgap.com -- Friends don't let friends use Windows. -------------------------------------

Does anyone know anything about this? The owner is completely ignorant about this sort of thing and wonders if he should just scrap the whole thing. Hmmm, the TIROS system was WAY before Multibus and M68K, the first one went up in 1960. I have a few bits of the TIROS sun angle computer, and looked at some of the gear that recorded the slow-scan images to film. Alden was the big maker of weather fax machines in the 1970-1980 range. The date on the plate indicates it was a 1984 NOAA contract and the unit was built in 1987. I can't believe there was any TIROS system operational at that time, I suspect the TIROS label was a historical artifact in Alden's documentation, and that this system was actually used to receive and print out GOES images. The GOES satellite sent high bit rate data while the mirror swept the image of the earth, then received a processed image from a ground station during the time the mirror was sweeping space and relayed that to ground receiving stations for printout. Ships at sea could print out weather maps in near real time, for instance. Jon

IBM model 71 printer

by quapla＠xs4all.nl

During some cleaning of the attic I found an old (and forgotten) project of mine. It is a sort of printer, build around the back half of a IBM model 71 typewriter. >From what I remember, I got this from a thrift shop a long time ago, I guess I was a little intrigued about it. It looks like it was modified by a company of some sort (not IBM), and what they did basically was to cut off the keyboard section of the typewriter about half an inch from the cover which can be lifted. To be able to use the mechanism, they added a bar with solenoids which pull the little levers as well as to operate the clutch, advance one position and do a mechanical CR/LF. Also an paper roll holder (for teletype paper rolls) was added as well as a electrical switch & cover plate for being able to close the front. When I got it, it missed 3 solenoid for some of the little levers, finding a replacement should be possible, although they will be different I guess it should be possible to make some sort of interface for it to let is work as a simple printer. I was just wondering which company did these modifications. Any idea's? Ed BTW it runs a little slow, nothing a careful lube job will fix :) -- Dit is een HTML vrije email / This is an HTML free email. Zeg NEE tegen de 'slimme' meter.

PDP11/05 front panel switch

by iamcamiel＠gmail.com

Hi Again, While I'm still struggling with the powers supply in the /84, I decided to also take a good look at the /05. Amazingly, the power supplies on this one (1972) are 13 years older than those on the /84 (1985), yet their outputs look absolutely perfect. Plugged in the cards, and it seems to work, apart from one annoying little thing: one of the front panel switches is bad. I noticed it when I was depositing, then reading back some data, then took a multimeter to determine that it's the switch itself that's broken. Cosmetically it looks ok, but it doesn't work. It's just one of the address/data switches, all other switches work fine. Are there any replacements for these switches to be found? Camiel.

I personally would have pronounced these MS-DOS version numbers variously as "three point three," "three three," "three point three oh," "three three oh," "three point three one," or "three three one." As to the earlier part of this thread, on which systems had these various versions of MS-DOS: Yes, indeed Zenith provided/used 3.31.

Wow, I think any of this gear would be very unlikely to have been saved. I know Washington University had some SAGE pieces in a warehouse, but I haven't seen any 7090-vintage stuff in ANY museum collection. It is kind of a big hole in their collections. The tube stuff all went in the dumpster as soon as transistor and core memory came in, and the early transistor machines had an even shorter life than most computer generations. Hmmmm, now that I think of it, I think WU also had a 7094 memory unit - all tubes, kind of in the transition between tube and transistor. I remember it because an address wire had burned up and somebody had threaded a wire through all the burned places to get it running again. A horrible kluge job, too. Hmm, that one was not oil-cooled, but maybe the damage I saw was WHY they went to oil cooling. Jon

IBM 7090 mainframe!

7090 and 7094 are discrete transistors, not tubes. 709 is tubes. All three exist in collections, I think, though maybe not in running condition Google will help out find them.

Looking for Data I/O "calibration extender" 910-1521

by chrise＠pobox.com

After removing the PROMs from my RX02 controller and attempting to extract their contents, I've discovered that the Unipak for my Data I/O System 19 has a failure. It's returning Error 70 whenever socket 6 is accessed. Of course socket 6 is the one the 7643 PROMs need to go in. Error 70 means something's wrong with the "bit supply". Data I/O built a "calibration extender", P/N 910-1521 that was used to enable probing of the Unipak while it was raised up and out of the main chassis. It would sure make it easier to work on this thing if I had access to said extender. Does anyone have one they would be open to loaning out for a short while while I attempt repair of this unit? Or, better yet, does anyone have one they want to sell/trade? Chris St. Paul, MN USA -- Chris Elmquist

PDP11/05 front panel switch

Does anybody have the CD for this book

by microcode＠zoho.com

I just bought a copy of Computer Organization and Design, Third Edition: The Hardware/Software Interface, Third Edition (The Morgan Kaufmann Series in Computer Architecture and Design) Quality: Used - Very Good And it is in nice condition but missing the CD which is a bummer since the Appendices are not printed in the book itself but are all contained in the CD. Does anybody happen to have a copy of this I could ftp or download somehow? Thank you.

I'm not saying they will, but based on their current logic the conversation could go along these lines: "OK, you have a machine that shipped with a valid OEM license for DOS 3.30. Did you get the original media with that? No? Well, for a valid license transfer to occur you need to get the original media. If they were destroyed, unreadable or not given to you then the license was not validly transferred, and you would need to reacquire a license. We no longer sell these licenses, but you may be able to find someone with validly licensed Retail MS-DOS software for sale." My guess is that they probably won't care unless you ask them (most companies wouldn't care in this circumstance), but then again sometimes they do - or somebody in legal decides they need to justify their job's existence. MS is getting very creative with limiting the newer-not-relevant copies of Windows, though my guess is that this is to give them an out if someone calls complaining that their copy won't activate.

I'm pretty sure that they have a department tasked with inventing "license issues" whenever possible to increase revenue based on some of the things that have come out of there - they're pretty creative.

VAX/VMS object file format?

by legalize＠xmission.com

I was reading this article on Microsoft PE file format, <http://msdn.microsoft.com/en-us/magazine/bb985992.aspx>, and it mentions that the PE file format is a derivative of COFF from VAX/VMS. Wikipedia's entry for COFF mentions a System V unix heritage along with Windows, but doesn't mention VAX/VMS anywhere: <http://en.wikipedia.org/wiki/COFF> Given that NT is heavily influenced by VMS via Dave Cutler, it doesn't surprise me that COFF also has a VMS heritage. Can anyone comment on this? A little quick googling for "VMS executable file format" didn't yield any enlightenment. -- "The Direct3D Graphics Pipeline" free book <http://tinyurl.com/d3d-pipeline> The Computer Graphics Museum <http://computergraphicsmuseum.org> The Terminals Wiki <http://terminals.classiccmp.org> Legalize Adulthood!

To get work from torque you have to multiply by radians, the angle of rotation over which the torque is applied. Similarly, power, being work per unit of time, from a motor-car engine is proportional to torque * rpm. Not very clearly expressed :-( but you get the idea I hope. /Jonas

H7202KA power supply

by iamcamiel＠gmail.com

Hi Guys, I managed to get the two DEC cabinets into the attic. Turned out I could just handle them by myself, without removing any rivets (emphasis on "just" as in "barely"). I've now got some of the Unibus PDP's in my hobby room (a /05, a /24 and a /84), so I figured I'd start with the latest model of the three.The 11/84 has a H7202KA power supply (H7200 + H7211 + H7213). All voltages look ok with a multimeter, but on my scope, the +5V VBB supply looks like a sick puppy. It looks like a sawtooth, with a period of 170 msec (ca. 6 Hz), and an amplitude of about 400 mV. Add to this a peak of 300 mV for 30 msec at the beginning, and a spike of -500 mV at the end, and there's a peak-to-peak difference of 1.2 volts. There's also some random spikes. In the end, the waveform looks like this: 5.5v -> |-_ |-_ | | | | | |__ | |__ | --__ | | --_| 5.0v -> | --|_ | --__ | | --__ | --__ | | --__ | | --__ | | || | || 4.5v -> / |/ |/ | | |----------------------| 170 msec The measurements were taken with the power distribution board and minimum load module plugged in; I don't want to plug any other modules in while the power looks like this. Is there any documentation available on this power supply? Or, does anyone have an idea as to what's going on here? The 6 Hz frequency strikes me as odd... Cheers, Camiel.

Hi All, I know this issue well. ?We are getting ready to sell the house and move so the collection is being readied for local sales. I've personally been collecting since 1982 when the IBM PC started replacing earlier computers in shops and homes. ?I found I could now pick up the systems that before I could not afford. ?I never tried to get them all, just the ones I really liked and some are even NOS. These are a lot heavier than I remembered! ? ? Regards, --Bill ________________________________ For Spammers:?Fight Spam! Click Here!

TU58 emulator

by cube1＠charter.net

I agree, but only because RL's and an 11/23 are pretty light. Change that to an 11/34 in a 10.5 inch box and a couple of rk05's and, over the years, things might sag over time - the posited fat people would not be sitting there day after day all day long. The analogy I usually think of is a water bed in an older house. The extra plywood helps, and is may also be helpful to have heavy systems along a side, rather than in the middle of the floor. Since I am not a structural engineer or anything like that, I guess it might depend on the spacing of the joists and the subfloor construction, and, on the sides, what kind of loads the walls are designed to bear. (In my case, my collection is on my basement concrete floor, and most of it is along the sides.) mcguire at neurotica.com wrote: > > You are not even remotely in dangerous territory here. > > For some perspective, think of a sofa with "feet", with two or three fat people on it. > > -Dave > >-- >Dave McGuire, AK4HZ >New Kensington, PA > > >On Jul 28, 2012, at 4:51 PM, Earl Evans <earl at retrobits.com> wrote: > >>> This conversation has started to worry me about the PDP-11/23 system in my >> daylight basement/family room.

One thing you should also consider is the weight loading you are going to put on your attic, and how it is distributed, less your ceiling sag over time.

Commodore C286-LT

by reiche＠ls-al.eu

Hi guys, Wanting to run the older Unices, I hunted around for a working 286. I sort of succeeded, except for the part that the sealant from the original Connor harddisk probably didn't get enough air where the laptop was situated for the past ten years and had gone fluid. Messy. Got me another harddisk, also an old Connor, not sure if it works but can't seem to find anything like a working DOS floppy with a FDISK.EXE which allows the removal of non-DOS partitions. A guy at work had a working copy of Partition Magic on floppy, but it seems to have a heavy case of floppy rot so it won't boot. So I was wondering, anyone have a floppy .img which I can rawrite or dd to a floppy to see if I can partition the old Conner or another 2,5" disk proper, so I can at least install MS-DOS onto it and maybe some old Unices later on? Thanks in advance and re, Sander

I've got it up and running. The problem is in trying to run fortran. There's a FOR.OLB in db0:[11,41]. When I try to run for, I get TASK NOT FOUND. When I run ins $for to load it, it reports not being to find the file. Being a total newbie at this, I'm not sure how to get it to run. Any ideas? As Jay says, .olb is the object library, which gets linked in with your compiled code to supply the fortran-specific library functions. There should be a FOR.EXE, I think, for the compiler. It's been a while since I ran RSX11/M. A LONG while, like 30 years! Jon
