In the list I posted, I included anything that was vaguely a computer, like
the Psion and the AgendA, and the Torch, which is really a second processor
for a BBC B. I didn't include terminals, such as my VT131, a couple of
Cifer terminals, and some Wyse terminals. If the WP-2 runs software, even
just a dedicated word processor, I'd probably count it.

he did have a website called retrocomputing.com but i am unable to establish a

had made.

A friend has an RP06, an alignment pack, and the alignment tool, but
lacks the instructions to do the deed.
Anyone got the manual that describes the procedure, or know how?

The old Beige cases are made with Borg-Warner's ABS Cyclolac using the
color PMS 453.

In the old days, I used to work for a company that made hard disk
subsystems for the mac. When Apple changed to the "Platinum" color
scheme, they sent out a paint sample with a pantone color #. Someone
MUST know what it is...

Hmmm. I would probably go with a really fine sandpaper to give the paint
something to stick to, then if I wanted, clear coat the finished product
for a good seal against possible flaking. I painted a 14" SVGA monitor
once. Flat black, straight out of a cheap spraypaint can. It never flaked,
but some did rub off when I moved the monitor. I touched it up with black
magic marker.
I have this weird idea that one day custom paint jobs on computers might
make me some extra money. Am I crazy? Do you think there would ever be a
market for it?
I've seen one guy on the net that has built custom mahogany and marble
cases for his Mac cx and others. Was cool to see a more recent Apple in
wood. :)
Is this off-topic?

Actually, there is a little known difference on the power supply board
between a beige Mac plus and a Platinum Mac Plus. Just a diode but boy
oh boy did it cause havoc when installing a certain CPU accelerator
board made by now defunct MacMemory.
Mommy! I let the magic smoke out!

I've been tempted to do that too. :-) What kind of paint would be best
for this? And how would you go about cleaning the unit before hand?

Yes there is a device used to count particles in the air. But you may not
like the cost of them.
My job involves work in our Class 10,000 cleanroom at my place of
employment. A few of you others out there either once had or now work in
such a company that has cleanroom(s), or possibly had spent time in a
cleanroom as a service person.
I can give a brief primer on how a cleanroom is built and short definition
of the federal standard of cleanroom classes if some of you are interested.
That would give a picture of the environment within which the drives had
been manufactured and what one would do to make a simple one for his/her use.
We make linear encoders of which the finest line size of the ronchi ruling
on the encoder substrate is 4 microns (157.48 millionths of an inch.)
Figure one micron = 39.37 millionths of an inch (0.00003937"). Most dust
particles in 'free air' (the air we normally live in and breathe everyday)
are in the 0.5 to 10 micron range. Therefore, keeping the air _clean_
during the manufacturing process has benefited us extremely well. Of
course, semiconductor manufacturers fabricate microprocessors, transistors,
all other IC's in cleanroom environments. Those hokey Intel TV
advertisements with cleanroom workers in full body suits are actually not
far off the mark with regard to the actual need to keep a class 10 or 100
cleanroom clean when making chips with sub-micron features.
I had purchased a particle counter at work to check the "cleanness" of the
air in various zones in the cleanroom. These machines are somewhat
complicated though the basic concept used for counting particles is not.
Most particle counters are sensitive. The one I bought is able to "see",
therefore count, a *single* particle as small as 0.5 micron. Our unit has
similar specifications as other typical brands of particle counters but it
still cost us a little over US$10,000. Used equipment dealers have them for
less but it's still not reasonable for the hobbyist or even a very small
business. Maintenace parts and calibration is also a bit high.
BTW, the air quality in most areas of our cleanroom stays at less than 100
particles per cubic foot. Very clean when considering that outside air
which is relatively clean (say, the proverbial fresh mountain air) has
100,000 to 500,000 particles per cu. foot -more with forest fires, etc.
nearby.
If I do decide to tinker with some of my dead hard drives, I plan to bring
them to the plant some weekend and have at it :-) I'll just slip on a
boufont (sp.?) cap as a hair cover, special gloves, my lab coat and maybe a
face mask of some sort, setup at an empty table and away I go!

This is an extremely simplified version of a particle counter. I can
envision it as having a simple LED emitter, probably IR, on one side of the
hose and a photodetector on the opposite side. The detector and the analog
front end may be rather sensitive to differentiate minute changes in light
intensity. When significant amounts of dust and crap are sucked thru the
hose the light is slightly occluded whichs lowers the output of the
photodetector which then trips the circuit driving the red LED on your
Panasonic vac. This is much too coarse of a device to measure air quality
in any home-built glovebox/cleanroom any of us may build. It serves to show
the homeowner that the Panasonic company's wonderful Model Such-and-Such is
doing a great job at cleaning their house. Pure marketing gimmick but kinda
neat on a home vac anyway IMO.

Thanks for starting the discussion Sam, as a few of us who have the
resources will need to get into it in the future -if not now. I can offer
additional ideas and advice from my own cleanroom experience to the group
on setting up a work area using either homemade or used commercial "clean
benches", etc.
