The first TWO hits that I got are for Dial Electronics. They have the part listed but don't say what it is, who made it or how much they want for it. The next two hits are for HKinventory and they give the same lack of information. Then USBid, Doom, and others. NONE of them give any information about the part at all. Thre are pages and pages of the same kind of useless hits. That's why I'm dumping Google! Joe >Peter Wallace >Mesa Electronics > >

Time to purge!

by nerdware＠ctgonline.org

I'm officially giving up collecting. When I started, I didn't realize the amount of space it would take, and I also didn't realize that there were people out there with 1000 times more stuff, who actually had time to use it.... I've gotten rid of most of it a couple years ago, but it's time to get rid of everything except my original Vic20 and C=64, and my 2 Amigas. Here's what has to go: 2 Apple IIGs cpu's, one 5-1/4" floppy, one 3-1/2" floppy, modem and monitor 3 Apple Disk ]['s Apple ][e Apple ][ Monitor for ][ (monochrome) Macintosh Performa 400 Imagewriter ][ Smith-Corona Daisywheel printer (was used with Kaypro II) Commodore Plus 4 IBM PCjr box of Kaypro software miscellaneous Apple software other crap as I come across it I just want this to go to someone who has time to play with it. You pay shipping -- it's yours. Or, if you're in the Chicago/NW Indiana area, I can arrange for pickup. I want this out of here by the end of next week. If nobody wants it, it will unfortunately go to the recycler. Email me. Thanks.

Looking for TC08 Wire List

by vrs＠msn.com

Hi, Does anyone out there have a TC08 wire list? I am thinking of creating a replica TC08 and need a way to check my work. ECO information would be good to have, too. Thanks! Vince

Matrix 3U CPU card?

by mpokorni2000＠yahoo.com

Matrix might have been a maker of VME CPU boards, but video board maker from Montreal was named Matrox and they are still in existence, web address is: http://www.matrox.com/ . You might want to try VITA's web site: http://www.vita.com/jun96vj/toc.html for some information on Matrix' CPU boards; VITA is VME maker's association and they might have information on legacy products. Additionally, you can try search on Google for all three words: "matrix cpu vme". Regards Miroslav Pokorni

Comparing existence of massive number of files

by rcini＠optonline.net

Hello, all: I just moved most of my collection of on-line data to a new server here at home. I want to verify that all files have been copied and I didn't miss any directories/subdirectories. Basically I did it through a drag-and-drop across the network. What's the best way to do this? The OS is Windows NT (Server) and I'm looking at about 22gb of files of various types -- from music to source code. Any ideas? I still have the original server on standby for this verification before I wipe it clean for sale. Thanks again.

anybody know of GOOD serach engine?

by rigdonj＠cfl.rr.com

Does anyone know of a good internet search engine? I've been using Google but they have gotten LOUSY in the last couple of months since they've decided to sell the "right" to companies to be first in their search results. It's gotten so bad that I can no longer find anything with their searchs except ads for totally unrelated items. Joe

X-Tree Gold 2.5

by Lee.Davison＠merlincommunications.com

As above, boxed with the manual and, I think, both sets of disks (3.5" and 5.25"). Available for postage but hurry 'cos the binman comes in the morning.

running 3 phase motors from single phase...

by julesrichardsonuk＠yahoo.co.uk

Rats, I just found out the museum's dead Sperry drum store uses a 3 phase motor - is there any way I can run this from a single phase supply (UK mains, ~240V, 50Hz) without things blowing up? Or am I resigned to replacing the motor with a single phase equivalent? I just want to get the thing spinning so that people can hear it running - it's way beyond actually being able to restore it to working condition again :-( cheers Jules

However, 10baseT transceivers and microtransceivers are cheap and easy to come by. Well, for me anyway :-) Structured wiring is also useful for serial connections, a phone line, ISDN, and all sorts of other things. > If possible, have a good isolating transformer.

Also think about having both 110 and 220V outlets -- the > ability to plug in just anything from either side of the Pond, at least > for testing is very useful. I have an isolating transformer, which lives under the bench. I've almost never needed 110V, but one day I'll find a cheap transformer. > My iron is normally on my bench, but I do move it around for work on > minicomputers, etc As an aside here, if you're in the UK and work on DEC > machines, make up adapter cables for 13A mains plug to US 234V socket and > US 234V plug to 13A mains socket so you can (a) plug a DEC unit in on > your bench for testing and (b) can run your soldering iron, 'scope, etc > off the power distribution unit at the back of your DEC rack. I've got an adaptor but since there's a DEC rack right behind me as I sit at the bench, and the room is small, I rarely need to plug anything in at the back of a DEC rack. Anyway, the adjacent rack has a 13A rackmount power on it, and there are several 13A sockets on the wall behind the other racks (three racks in total). > Although I don't do much heavy metalwork on my electronics bench, I agree > a small vice is very useful.

The vice in question is too small and light for crimping connectors. I just use it for holding D-connectors, or holding multicore cables when I tin the ends. But the adjacent bench has a proper engineer's vice (a Record No.3), and there's a 3" vice on a Workmate at the other end of the room (all of 4 metres away). -- Peter Turnbull <postmaster(a)dunnington.u-net.com>
