Good - That is the only one I have info on that is handy. Both jumpers out (A&B) it will respond at CSR174420 vec164 The alternate add is CSR 174400 CSR 160 with Jumper A installed. I have had one for some time but have not taken the time to play with it. It is SCSI but it responds at an RL add.

I found an HP150 (model 45851A?)--how do I make it work?

Hi Kevin, >....I picked up a lot of cool stuff, but the real prize was an >HP model 45851A (I think) 'Touchscreen II,' a.k.a HP 150C. Nice find. >....But I don't think anyone in the company still has the disk >media. I can't imagine there being any other options besides >the HP version of MS-DOS that it shipped with.... I can send you a Teledisk image of the DOS disc if you need one. Other than that I have no software for the machine. Hardware options included several different RAM boards, one with built in HP-IL interface, various floppy/hard drive units and the touch screen itself (I've NEVER seen a machine with the touch screen BTW). Do you have some form of drive unit for the machine? Without one all you have is a dumb terminal.... TTFN - Pete. -- Hardware & Software Engineer. Sound Engineer.

Sams Photofacts (Was: Re: Rejuvenating VT320 monitors?)

But the only real electronics shop in the area can't get > Photofacts any more... I honestly don't know it they do exist anymore, haven't had a need in years. The last time I saw a current Photofact, it was nothing more than a reprint of the manufacturer's material. It was not the Photofacts of old so I just sort of forgot about them. I think I bought my last one aroung 1976. It so happens that my first electronics job was with Sams PhotoFacts. That was about 30 years ago. At that time they actually acquired one of each model and tore it down to produce the photos and schematics. My job consisted of unpacking the TV, then setting it up with a mess of sensors attached to critical components to measure various parameters. I also disassembled the TV and wrote the disassembly instructions, did the chassis overview drawing, and chassis overview photos calling out the major controls and components. After that the cabinet and CRT were stored and the chassis sent down the 'line' for schematics to be drawn and parts lists produced. That process took 6-8 weeks. The fun part was after that, the set had to be reassembled and restored to working order. During the time on the line, the chassis would be handled by dozens, dropped, kicked, spilled on, and who knows what else. It was a nightmare sometimes to get a set working again, but I learned a lot. Fortunately, it was not my job to reassemble all of them, just something we all did when lacking for something to do or in need of a change. Some of the perks were nice, like a free subscription to Photofact of the Month. The was a file room where 50 or so copies of each individual Photofact were archived. You were free to go there and pull anything you needed. If it was not there, then tell the secretary and she would order it from other archives. One time I needed a Photofact for what at the time was considered an antique radio. I told the secretary and the next day she brought the complete folder, #47 as I recall. I have long since forgot the original issue date on that one. The other neat thing was the quarterly employee book sale. Needless to say, I have my share of Sams books, the paperbacks all bought for a quarter each. It pained me in later years to have to pay full price. I remember even back then that they were cutting back there 'coverage' of things like clock radios and the less expensive TV's. I guess you can call it the dawn of the age of 'discarding'. So I have to wonder what kind of coverage they provided for VCR's. Forgive me, John (et al), for not really answering your question. I had not even though about Sams in years and your posting prompted me to share. Excuse the rambling about old times. Mike

HP9114B battery pack

IBM 3363 optical drive Technical Reference Manual wanted

by Philip.Belben＠powertech.co.uk

> As the subject says, I would like to get hold of a Technical Reference Manual > for the IBM 3363 WORM drive. > > Any ideas where I might find one? (And an ISA adapter card for the 3363 too.) I thought I had this manual, but alas, no luck. What I have is the Guide to Operations. A pretty lusing manual, all told, but there is some useful info to be gleaned, like the switch settings for the ISA card. (I don't have the card - sorry). The manual also comes with about half a dozen disks of drivers and software - I think it's Drivers for ISA on 5.25 in; drivers for ISA on 3.5 in; and drivers for microchannel on 3.5in - two disks each or thereabouts. Details of the utility programs can be found in the manual. I haven't read it in detail, so I don't know how good an API you get with this. If you want this, shipping to USA is between 8 and 9 dollars (haven't got an exact figure - I just shoved the manual and one Jiffy bag on the scales in the post room), so I'll send it for $10 US. If you are not as far away from the UK as that, or want me to send it without the binder (a shame, since this is original and in good condition), the price can come down. Please e-mail me privately if you want this, and we can exchange addresses, etc. Philip. ********************************************************************** This email and any files transmitted with it are confidential and intended solely for the use of the individual or entity to whom they are addressed.

VCF 1.0e - VCF Europa in Munich, Germany!

by dastar＠siconic.com

I'm very proud to announce the first version of the Vintage Computer Festival in Europe! VCF 1.0e is scheduled for April 29-30 in Munich, Germany. Our beloved Hans Franke is the primary organizer of the event. I will be attending the event as well so I look forward to (hopefully) meeting a lot of you European computer collectors. The initial web site for VCF 1.0e is up but is currently only implemented in German. Complain to Hans. http://www.vintage.org/europa I hope Hans will find the time in his busy schedule to translate the site to about 7 other languages, but maybe someone can help him out. I think you silly Europeans should just adopt English already but I guess that's a flame war waiting to explode so I won't say anything (ooops :) Please send all flames and offers of assistance to Hans Franke at <hans.franke(a)mch20.sbs.de>. Unfortunately I know little about the event with regards to location, admission, etc. Hans has been doing all of the organization and we haven't been coordinating very well. All that information is on the website but I can't read much German yet unfortunately. My end of the bargain is to learn German fluently enough to give a 45 minute talk at the event. So at some point I should be able to read the pages. For now I remain an Ugly American. Oh well. I hope to see you there! It will be a BLAST! Sellam International Man of Intrigue and Danger ------------------------------------------------------------------------------- Looking for a six in a pile of nines... VCF Europe: April 29th & 30th, Munich, Germany VCF Los Angeles: Summer 2000 (*TENTATIVE*) VCF East: Planning in Progress See http://www.vintage.org for details!

IBM 4381 Avbl in South Australia

by geoffrob＠stmarks.pp.catholic.edu.au

Anyone able to tell me something about this type of system? It's about 300 miles north of me, and I'm considering submitting a tender for it. Some idea of it's value, probably as scrap (since that's who I'd probably be bidding against) would be good. FWIW, I personally feel it is historically significant in view of the job it did and worthy of preservation. The system is from the (now closed) Joint US/Australian Space Defense facility at Nurrungar, near Woomera. ('Way out in the desert of northern South Australia.) The entire place is up for sale by tender, houses, buildings, radomes, dishes, power & AC plant etc - plus the IBM Mainframe that did all the data processing. Quote: "The Data Reduction Centre used the IBM 4381 Computer System to process and record infrared data detected by satellite and transmitted by the Satellite Tracking Station (SRS). The raw Satellite data was relayed through a variety of computers and electronic equipment and finally to the DRC's IBM 4381 mainframe computers. The mainframe computers each had dual processors: a support processor and an instruction processor. The processors filtered out any spurious data by comparing the data against pre programmed event criteria. Data that were not needed were discardedwhile data that met certain criteria were formatted and sent to the SOC for further evaluation, this time by human beings." End quote. There are numerous pics of the the system at:- http://www.evansclarke.com.au/megatender/usaf_ibm_4381/index.htm If you click on one of the thumbnails it will show a large version of the pic with a next button to go through all of them. If you want to see the other stuff that's on offer take a look at :- http://www.evansclarke.com.au/megatender/index.html Cheers Geoff Roberts Computer Systems Manager Saint Mark's College Port Pirie, South Australia.
