I don't even have an APC anymore. But since this thing is eyeing me menacingly I figured I'd put the request out. Butler Flats Associates dual external 5 1/4" accoutrement, has it's own controller card (based on wd1771/1772 iirc). Contact me off list if you have these. Much appreciated.

A quick note on ADM3a screen rot... my vintage collection resides in a cool
(60-72 degrees F) dry basement. My "pride and joy" ADM3a (I have several)
was just starting to show a few bubbles at the corners last September. I
was pulling out some parts units on Friday and noticed that one had a much
better screen than I remembered. Thinking that I might swap screens, I took
a close look at "PnJ" and discovered to my horror that most of the lower
half of the screen had "melted". "PnJ" was on a shelf, below eye level,
nowhere near a vent or other source of heat. I was so annoyed that I
immediately started cleaning/repair without taking any pictures (sorry).
Fortunately, there does not appear to be any corrosion from the "goo". I
completely desoldered and removed the keyboard assembly to get all of the
crud out of (and out from under) it. The mainboard is a fully socketed
example and the crud is down in several of the sockets. I'm still working
on that. Anyway, the take away is don't assume (like I did) that the ruined
ADM3as you see are the result of temperature extremes. It can happen
anywhere. Keep a close eye on yours if you have one.

I am working on a deal which includes several PDP11/15 or 20s. I will be
looking at them next week and hope to get more details. I will look for
exact model numbers and configuration.At least 2 of them have non DEC
silkscreens on the front panel.
Also a selection of 11/05 and 11/10 including 5 1/4 box, BA11-D, and BA11-K
units.
If you are interested in a box or parts please email me off list.
Thanks, Paul
The Apple Mac, 40 years old, came from Xerox PARC’s GUI and Apple’s LISA.
Not sure that it really changed computing though! Financially it didn't
help Apple until after 1997 and Gate's investment.
Happy computing!

I've been hunting for a while now for OAK PCB mount keyboard switches
that I can't find a part number for. I've attached a product listing for
the switch that shows it pretty well. DPST-NO preferred.
Only $0.40 in the early '70s!
Any quantity considered...
Thanks!

It's not been near a computer since 1979. It's currently in Fred van
Kempen's storage.

In 1979, the Dutch team of Harry Whitfield's students writing the
Groningen University Time Sharing O/S called GUTS sent an RK05 to Edinburgh
for us to try out on a PDP11/60 we had access to in Steven Salter's
Wavepower project lab. Ian Young spun it up and learned how to use it.
After some years of being out on loan, we hope to have the disk pack
returned to us this year, so I'm now looking for someone reliable who can
recover very old disk packs, preferably in the USA where we can ship the
pack to them, without having to go through customs and risk damage in an
inspection (I remember those scary 1970's diagrams showing the
comparative size of a smoke particle next to the gap between the heads and
the disk surface!). To minimize the risk of damage during shipping, I'm
hoping that the person who currently has it can ship it directly to
whomever we can find who can read it for us, rather than to me and then to
that person.
I'll be happy with a raw disk read, but the GUTS file format should be
backwards compatible with RT11 files so if the disk is readable I don't
think we'll have trouble getting the data off, especially if the person
with a pdp11 runs RT11 on it. If we can get a disk image however I think we
could get it running again under emulation.
Please contact me at gtoal(a)gtoal.com if you know of anyone in the US who
might be able to read this disk pack, or contact them and ask them to
contact me if they're interested.
Thanks,
Graham <gtoal(a)gtoal.com>
PS We have the 3 GUTS manuals in pdf format, but that's the only GUTS
documentation that we know of which survived:

FASTBACK bak up ptogrsm...Help how to recover files stored in this backup format,?
Back when the museum was next to computer exchange Inc. Pre '94. We put out a journal once a year Over 100 pages tightly leaded would like to access files and reprint. Would need Pagemaker 3 orveoukd data files be upward compatible with indesign by adob?
