Lesson to be learned (besides being civil in court), always claim the most worthless item in the collection is the most valuable. That way she runs off with easily replaced junk and leaves all the real good stuff behind. -chris <http://www.mythtech.net>

Removing duct tape residue.

For use as a plastic cement, it's usually thickened by dissolving ABS or PVC in it. Pure MEK is a very light colourless liquid. -- Pete Peter Turnbull Network Manager University of York

Infotek Info RE: HP 9000 300 data acquisition card - Infotek AD200

by rigdonj＠cfl.rr.com

Peter, Did you ever find out anything about this card, other than the technical description that someone posted? I THOUGHT I might have a manual for it and I went looking for it today but didn't find it. (I'm still looking). However I did find an Infotek manual for a 2Mb memory board for the 9000 200s. It says that Infotek is a division of ALS Corporation and their address was 1400 N Baxter St, Anaheim, California. This manual is dated 1985 so they may or may not still be around but it might help in your search. I think there are several list members in that area, maybe you can get one of them to search locally. I have several Infotech devices including ROMs for the 9825, 9845, a memory card for the HP IPC and a couple of these 2Mb cards for the 9000 200 computers so I'd like to try and track them down too. One thing that prompted me to look for the manual is that I'm working with Bob Shannon on HP 1000s and he has a card for the 1000 that sounds like it's exactly the same thing in a different form factor. Even the specs look the same. We're trying to figure out how to program, trigger and read it and I'm guessing that that will be the same for both HP cards and your Infotek card. Joe > >Peter, > > What kind of terminal(s) does it have? It sounds like it might be a A/D or perhaps a D/A card. HP made some A/Ds I think I have some docs on it somewhere. I used to have one the cards I never got around doing anything with it. I never even pulled it out of the machine so I don't know if it was made by HP or if it was made by someone else. IIRC it had a row of screw terminal on the back side of it. I looked through the manual for the HP A/D card at one time and I don't think it took any special software. The system treated it somewhat like a GPIO card but the digital value that was input was converted from the analog input. If you output a digital value to the card it selected the channel number (12 channels as I recall) and range. If you think your card may be a A/D, I'll try to find the docs that I have. > > I forgot to ask, is this a DIO card? > > Joe > >At 09:47 PM 5/3/03 +0000, you wrote: >>Hi All, >> >>I've just acquired an HP 9000 series R332.

Leaving the hobby

[spoken very matter of factly and calmly, >then just let any arguments, shouting, screeching, etc. go in one ear >and out the other] My first wife called this bluff and left, leaving me with the son and all the bills. She filed property settlement papers that placed the value of my collection at over $10,000, including my Kaypro 10 at $2,500, a PS2 at $1,500 and a 9 pin Epson at $160. The current wife is an electrician with a case of "Pack rat syndrome" equal to mine. The only classic related disagreements we have are over whose turn it is to use the ancient ones and how nice it would be to get 1/2 of the spare room for her stuff, I tell her that she can have the bottom 1/2.

Running PCs on 12v

by rcini＠optonline.net

Joe: >> >> Any chance of using 48VDC? There's plenty of surplus industrial PCs (and >>PSUs) that run off of that. I've often wondered if you couldn't run a PC >>directly off of 12VDC (with a regulator to drop one line to 5VDC). I saw a lot of these in my usual surplus catalogs but producing 48v from batteries of a sufficient amperage is a bulky proposition. I envision a small cordura camera bag filled with two surplus 12v 7ah lead acid batteries (in parallel) and some switching gear for the scope and the PC. I also looked at some of the mobile MP3 projects but the most suitable solution was $150 and didn't have the right amperage ratings. I don't know...maybe I'm looking for something that really doesn't exist. I really wanted to avoid building my own supply, though.

ISA Expansion Box

by RCini＠congressfinancial.com

I have one of these boxes. It appears that IBM took another PC case off the assembly line, stuck in a power supply and a passive backplane. There are two interface cards, one for the PC and one for the expansion box, connected by a very stiff cable -- don't recall what's on them but probably buffering ICs and the like. The cable is about 3/4" in diameter. It terminates in D-shell connectors but I don't recall the pin count (probably D50). The stiffness of the cable borders on inflexible and mine pops-out of the metal shell constantly.

They are a box with a passive ISA back plane and a pair of ISA cards that are connected with a single round cable about as big around as your thumb. The box itself is styled like an XT (down to the sloping front). -ethan The New Yahoo! Search - Faster. Easier. Bingo http://search.yahoo.com

VCFe Munich report

by Paul.HILLS＠landisgyr.com

Although the storage medium transferred to may have a shorter life, the information itself may have a longer life. As the previous poster said, he can store all his old 8-bit stuff in a tiny corner of his hard disk. That can get stored to CD. Now write-able DVD has arrived, it can be copied to an even smaller corner of a DVD. When the next, even more dense, medium arrives, it may be copied to an increasingly smaller corner of that. As long as this copying process occurs more often than the life-length of each medium, there's no problem. Keeping a copy of each intervening storage media gives you your backups too. There is a danger of leaving the information on the original only, as exemplified by the problems with the BBC's (UK) doomsday project (http://www.si.umich.edu/CAMILEON/domesday/press.html), which fortunately were solved. Even though it may be theoretically possible to resurrect the data, it might be very difficult. paul -----Original Message----- From: ard(a)p850ug1.demon.co.uk [mailto:ard@p850ug1.demon.co.uk] Sent: 12 May 2003 20:53 To: cctalk(a)classiccmp.org Subject: Re: VCFe Munich report > Hans' presentation on storing vintage computer data as XML made me > realise that the most important thing is to get everything preserved, > and then work out what to do with it.

I can assure you those paper tapes will still be readable long after your hard disk had headcrashed!. Why do people insist on transfering reliable storage media onto modern, unreliable stuff? It's the same with photographs and cine films -- people transfer them to CDs and DVDs. The originals have a much longer life... -tony

WTB: expanded memory cards (and more)

by xtguy＠mindspring.com

I noticed back in March that numerous people had Intel Aboveboard expanded memory cards for PC's which were offered on this list. I'm looking for at least several of the Intel that would work in an 8 bit slot (XT class) and several 16 bit ones that would work in a 286 or higher. I've been on this list for several months now (and I hope this isn't poor form) but I am looking for the following items as well: WordPerfect 2x or 3x for DOS Word for DOS 1x Morrow MDT-20, ADM-20 or MDT-50 video serial terminal IBM 5150 (case only) IBM 5170 (case only, power supply optional) Please contact me off the list. Thank you.
