Hi
Silicon oil is not conductive. In fact, silicon grease is used
to keep moisture out of high power ( high voltage ) RF connectors
in many applications. It does have a higher dialectic constant than
air but then most things do.
The reason it works well for sockets and connectors is that it has
almost zero film strength ( unlike petroleum based oils ). It keep
air from degrading the contact surface as well as keeping moisture
out.

And it's easy to get to from LI and NYC -- only 45 minutes (or less) from
the Throgs Neck Bridge (from the south) and right off of I95.
Stamford is also an option -- great rail links (Amtrak and Metro North) and
lots of hotels.

Danbury is also a superb area, you've got the Danbury Mall, there is also
the airport there, lots of hotels with convention centers connected, I think
also Metro North rail isn't too far either.

Yes, proper contact cleaner has oil in it. Not much, but some.

Hi
Many contact cleaners contain silicon oils. Contrary
to popular opinion, these oils actually improve contact in
sockets and edge connectors. Petroleum oils do just
the opposite.
I have used silicon based greases to improve the contact
of high current connectors when other methods have failed.
( DON'T use heat sink grease )

Hi
Don't spary it. Just put it in the oven at between 125 and
130F for a couple of hours. They will all die soon without
the bug spary.

Dwight's right, you don't need the spray. Apart from that, I would be
very wary of a "high pressure wash" -- high pressure anything can
damage tracks and plated holes by stressing them where components are
fitted.
If you do wash it, beware of any switches, relays, transformers, etc --
and *don't* dry it in an oven. You'll evaporate the water, leaving
behind any minerals (hardness in the water etc), some of which will be
hygroscopic and/or corrosive. Excessive heat can be a bad thing too.
It's better to give it a final rinse in water with a *small* amount of
wetting agent (so most of the water drains off), and blow away as much
as possible with *low-pressure* compressed air. Or rinse in iso-propyl
alcohol, which will remove most of the remaining water.

Marvin, glad to hear you were able to snag all
that stuff in LA!
While continuing to scour Ebay for an an obscure
minicomputer or a misplaced listing, I keep running
across interesting stuff that I have no interest
in buying myself, but I'm sure someone here on the
list would love to have. Here's what I came across
during this weekend's search:
1961 RCA 601 Mainframe Computer Antique
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2573945853&category=361
This is a set of cute little plastic miniatures of
an RCA 601 and its various components, along with
a fitted carrying case. Used by salesmen. A really
nice museum piece with an asking price to match.
Ouch!
antique computer sales book pamphlet c 1910
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2573607526&category=361
antique computer sales book pamphlet 1908
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2573612402&category=361
A couple of brochures for the British licensee of
the Powers tabulating machine. This was the
competitor to Hollerith who got the Census Bureau
business after they got fed up with Hollerith's high
prices. Powers sold out to Remington-Rand, I believe.
antique computer Hollerith census book 1891
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2573617998&category=361
A period reprint of an article on the use of
Hollerith equipment for the 1890 census.
RAF Tornado Computer with Core Store Memory
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2202934131&category=4238…
A small airborne computer. From what look like
date codes on the components, it looks like it was
made in the early 80's, which seems a bit late for
this technology.
Computer Space Ball by Nutting Associates
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=3253199680&category=1371…
The listing describes this as "computer space
*ball*", but I believe that Nutting Associates
was the maker of Nolan Bushnell's very first
video game, "Computer Space". This is just a
troubleshooting manual, though someone else had
the game itself offered on EBay in the last
few days.
VINTAGE 1970S SLASH 7 HARRIS COMPUTER MANUALS
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=3566572833&category=1107
Here are manuals for a machine I've never heard
of. Al, are you reading this? ;)

Hi all !
Check out this auktion at Ebay-Germany :
http://cgi.ebay.de/ws/eBayISAPI.dll?ViewItem&item=2764603836&category=8101&…
The best thing is, that the drive is untested...
The seller said that the drive spins up but no more tests. I suppose that the necessary equipment was missing.

Hi,
I wasted a few minutes making a picture of the DEC M750 module available at
http://mysite.verizon.net/res1ac3j. I doubt it will jog anyone's memory,
but what the heck :-).
It looks just like a DEC M-series module, to me :-).
