Hi,
I'm interested in getting a MOS Technologies KIM-1, Synertek SYM-1
or a Rockwell AIM-65. Has anyone got one for sale (preferably in the
UK)?
Thanks.

Thread drift and someone elses comment in there that was not quoted.

Why? ;)

I would agree. The mains switch on a Compact is only single pole. While
it will normally do the job, it might provide an unpleasant surprise for
someone in the future.

I'm pretty sure it can; the Compact uses a standard SMPSU in the disk box.
There should be a 110/220 link on it.
To open it up, you need to remove the front and rear trims. These are
clipped into the side trims, but also have two (or three?) bumps on top and
bottom edges which fit into small slots in the metal case. They're a bit
fiddly, and often very stiff the first time, but they will come off without
tools. Then you can remove the side trims, and if I remember correctly,
there are a few obvious screws to remove before sliding the cover off.
(Caveat: it's a long time since I've taken a Compact or an Acorn Filestore
(same case) apart).

I came upon a supply of brand new Consolidated RG-71/U 90 Ohm coaxial jumper
cables. They are 3 feet long and are terminated with a Kings PL-259 on one
end and a Kings BNC on the other. I don't know what they were intended for
.... although the connectors are very common RF items 90 Ohm impedance
isn't. Someone told me that RG-71/U might have been used in the computer
industry....... I don't know ???... but they are high quality factory
cables. I'm not sure but I think they were used with some type of
scientific equipment or sensor ????
If you can use these cables let me know ...... reimburse my shipping costs
and you can have them. Mailing should be between $3.20 and $6.00.........

[more about the computer rescue mentioned in my last message]
Unloading in Milpitas, CA will be even more fun since we don't have a
loading dock at this end, the ramp isn't wide enough, and the truck
companies won't rent trucks with lift gates for one-way moves.
Apparently they don't think that people move large heavy awkward items
one-way. It's a shame since I know from personal experience that a
VAX-11/780 (or 785) will just fit on the lift gate of Budget's 15-foot
trucks. (For safety, I recommend having at least three people to
stabilize a VAX while a fourth operates the lift. However, in an
amazing display of sheer stupidity, a friend and I unloaded a 785 by
ourselves.)
Has anyone had experience with forklift rental? I did a web search
and turned up *zero* hits. From a different rescue operation, it
is known that a forklift is a excellent way to move a PDP-11/60,
which is almost as big as the 11/780. However, that time there was a
lumber yard across the street that was willing to send the forklift
and operator over to help; this time there's no lumber yard nearby. :-(

Dammit, I was talking about new build. I know about the upgrades.

Ok, go to the old catalogs and try and buy a MicrovaxIII system as new
build.
The upgrade programs was a Field Circus project, successful but often
off the usual track.

Then it was an upgrade. My MVIII comments was ment to be reserved
for new built systems.

Maybe if you hold down the keys: RSHIFT+Leftshift+CTRL-YPBQZXHRT+SPACE
while switch in back whilst holding these keys. I've tried, it is
possible. You will have to put the system unit on the floor so you can
operate the power and toggle switches with your big toe or use your nose.

The ends of the wires connected to the switch are twisted together and
taped to the side of the case with a note saying "gotcha". One wire only
is attached to Rom disable pin.

Giggle. You seem to be very familiar with this device. Thanks for the info. ;)

This sounded very likely, however I flipped it back and forth while the machine was booted and nothing noticeable happened. Hmmm.

As to the design of the Sol case, did you know that it "inspired" Steve
Jobs' design of the Apple II case? In Michael Moritz' "The Little Kingdom"
it was written:
"Jobs thought the cigar boxes [housing the home-made computers]
that sat on the ... desk tops during Homebrew meetings were as
elegant as fly traps. The angular, blue and black sheet-metal
case that housed Processor Technology's Sol struck him as clumsy
and industrial ...
