See the ENIAC in person - well, part of it anyway.

by gilcarrick＠gmail.com

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.

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
