You guys must have a different Google than I have! 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!
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

Smith-Corona Daisywheel printer (was used with Kaypro II)

miscellaneous Apple software

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.

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:
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".
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
Any ideas? I still have the original server on standby for this
verification before I wipe it clean for sale.

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.

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

Many do, but a lot have AUI connectors. 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.

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.

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).

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).
