PowerWare 6000 UPS

by pete＠dunnington.u-net.com

Probably off-topic due to (lack of) age, but... I have inherited a PowerWare Prestige 6000 UPS. Anyone have any experience of these? It doesn't seem to like my mains supply. It trips the 16A (240V supply) breaker as soon as I turn it on, whether I have two, one, or no battery packs connected, and with or without any load. I've followed the procedures in the manual. It's rated for 19A at 240V, so I'm going to try a larger breaker; I'm told it always did have a large switch-on surge. Any other clues? -- Pete Peter Turnbull Network Manager University of York

Are office people really that, umm shall we say...slow?

In many cases, including the situation Russ is referring to, it's a matter of a manufacturers warranty. If I do *anything* to the monitor, and two weeks later the tube dies, the customer has no warranty rights. It's in the customer's best interest for us to send the monitor back to the maker for repair. Glen 0/0

email problems

by dittman＠dittman.net

Those of you I've been communicating with, my email is having problems due to my new ISP (GTE/Verizon) having messed up my DNS entries and not having any weekend DNS support (that sure surprised me!). If you need to contact me and mail to my usual email fails, try dittman(a)directlink.net. Thanks. -- Eric Dittman dittman(a)dittman.net Check out the DEC Enthusiasts Club at http://www.dittman.net/

Quite possibly a substantial charge... to verify this, perform a case study: convince a clueless office PeeCee "expert", or some random Micro$oft-brained IT manager, to wet their fingers and touch the right places. Figuring out a suitable explanation to make this agreeable to them shouldn't be too difficult - after all, the unit is safely unplugged from the mains socket, right? ;-) This will also demonstrate the correlation between failures of evolution and modern hiring practices.

anyone in the greater KC area interested in classic computers

by ghldbrd＠ccp.com

Just wondering you any of you guys know other in the KC Missouri/Kansas area interested in starting an informal classic computer group/club? Within a convenient radius is Omaha, NE, Des Moines, IA, and Topeka KS as well. As the usual sources of older equipment seems to be drying up, maybe those of us with an educated eye can network a bit more efficiently around here. Spread the word and have those parties e-mail me.

Are office people really that, umm shall we say...slow?

by Lee.Davison＠merlincommunications.com

Speaking of which, I'm planning to replace a CRT this weekend and naturally don't want to get a big shock. I've read that one way to discharge a CRT is to use a well insultated screw driver with an alligator clip/wire on the shaft of the driver comnnected to ground, and then insert the end of the driver under the suction cup where the anode meets the tube. Any thoughts on this approach? Don't connect to ground, connect directly to the wires that rest on the coating on the back of the tube. This will ensure that you discharge the tube. Also, if neither CRT has been on for a week, how much charge likely remains? Up to all of it. Also be aware that a tube that has been disconnected for any length of time may self charge due to electrolyte stresses. Not enough to harm you but enough to make you drop the tube in surprise.

NCR X-Station?

by donm＠cts.com

At swap today I picked up a neat little package made by AT&T/NCR in the early '90s. The package is 9.75W x 9D x 1.25H and looks rather like a book. The front carries only a push switch and an LED, while the rear has DB25F Parallel, RJ? and DB25F EIA, RJ? AUX, HDE15 VIDEO, and RJ? and OS/2 KEYBOARD connectors plus a concentric power input connector. There is an Intel 80C32 microcontroller, various static RAM chips, and a specialized NCR/ADDS SMD chip that pointed to X-Station information via Google. Anyone ever run across one of these critters and have any information on it? Also picked up a dual port SGX full length network card using DA15M connectors. I was intrigued by it carrying an NEC V50 PLCC chip. First I had seen. - don

Computer collectors meeting in The Netherlands 27 oct.

by kees.stravers＠iae.nl

Hi, I don't know if it has been mentioned here already, sorry for the dupe if it has been. The members of the Dutch computer collectors mailing list CVML are having a computer swap meeting for the third time this year. The focus will be on trading, where the members will bring machines they don't want anymore (and of course a few to show off with :) ). The list members mostly collect 8 bit micros from the 80's. Last time the meeting was a great success for me, I arrived there with a van filled with computers, and I left with only one :) The meeting will be held on october the 27th in the TwinType building at the Valkenierslaan 47 in Breda from 10.00 to 20.00 hours. There is a (Dutch language) web site at http://www.xs4all.nl/~rimmer/cvml/ For more information you can mail ton.brands(a)xs4all.nl Grtz, Kees. -- kees.stravers(a)iae.nl http://home.iae.nl/users/pb0aia/ http://www.vaxarchive.org Net-Tamer V 1.08.1 - Registered

>> expect a regular office person (and in some cases, even a regular IT >> person) to be able to do it. > >Office person, sure. But an IT person who couldn't solder a connector >gets no respect from me at all.... I don't disagree, but unfortuantly, Windows Crap OS and sleep thru "certifications" have bread countless morons that are now employed as IT managers. My company did a survey a number of years ago... college students, Computer majors and professors only... The LACK of knowledge, or simply WRONG knowledge coming out of these people was frightening, frightening to the core that these people were going to graduate and get jobs running the IT infrastructure of the US corportations. The only good thing that came of it, it finally convinced my boss that a college education didn't mean jack... which got me a raise (being a college drop out myself) -chris <http://www.mythtech.net>
