I have been trying to find good homes for some of my stuff, seems most people prefer to
recycle for the metal and plastic. Classiccmp has been a place I watch from time to time,
seems I'm always in the background.. So.. I would like to offer the following to the collectors
who subscribe to this list.
1. Compaq portable, model 1, dual floppies, software and manuals. Excellent condition.
2. Apple PowerMac, I have to check the model, but has a DOS compatibility card.
3. Original IBM EGA monitor, needs repaired, but is in excellent condition.
4. Two IBM PS/2 Model 25's, fully functional, used at a local college.
5. One IBM PS/2 Model 30, fully functional.
6. Original IBM 83 key AT keyboard.
I have other PS/2's 80's, 65, 70. I have to see which ones I have to find a new home for.
PS/2 motherboards and hard drives.
This is the tip of the iceberg as I really need to clear ALOT of stuff out, but do not want to see
it scrapped when I do believe I can find some in the Classic Computer list who may need parts/systems.
I am more of a user / collector of DEC stuff, microvax's, alpha station and servers.
Send any questions / requests, I will try to answer all

I have limited email connectivity right now, which is why I haven't been
commenting
on the recent archiving discussions. Apple development tools are easily
found in CD
form, staring with "Phil and Dave's Excellent CD"
I probably have a complete set, and I'm pretty sure CHM has one as well.
Apple
Developers CD's also show up on eBay.
re: deposition of collections when you're gone
contact the CHM registrar (allision akbay, akbay at computerhistory.org)
and she can
help setting up something if you would like to donate your collection to
the Computer
History Museum. I'm obviously biased, since I am responsible for their
software
collection, but I think that artifacts will be taken care of there.
I forgot to include three Centronics printers, models 779, 761 and 781. All
are complete and I believe they powerup. I have the service manuals for
the 779 and 761. These have been kept indoors in a clean environment since
I retired them in the early 80's. I am located in Butler, PA 16001

I was holding off comment on this, but today I found out
that both of the Orange County Goodwill operations have
been "reorganized" and new people are managing them.
Luckily, it looks like the people who are in charge won't
do anything out front, but there is no telling what the
back operation is doing.
I think one thing that is stressing goodwill and other
thrift stores out here is the "recycling" operations that
are picking up at the waste disposal centers here.
about 15 or 20 years ago, a friend in Kansas City
was a pioneer in the recycling of commercial equipment
with the Surplus Exchange. Bruce Holland recognized
that a lot of this was just stuff a bean counter wanted
off the floor that he was renting and would give it
to someone who carted it off.
He began taking not just computers but everything
not nailed down that an operation didn't want and
distributed it to a network of charities for free inKC.
In return most of their donations went to the Surplus
exchange rather than being turned away.
ANyway, now I see that the prices at goodwill for
such as 500 to 700 to 1ghz systems is still at the
$250 to $350 level, which is just too high. Also
a lot of stuff is going to these recyclers, so they are
loosing donations, I suspect.
Anyway, as to collecting old computers there is
probably not that much going to goodwill these
days. I suspect most of what comes out are old
pentiums, and P2's etc, and it would be pretty
hard to get upset with them for loosing the odd
old pile in all the stuff they have to deal with.
As far as the original posting, from Jim Battle about
Austin Goodwill. These operations are not set up
to handle a lot of variety in their input. They have to
move tons of excess every week, and simply don't
have either the trained or sheltered workshop manpower
to handle the odd stuff.
They are primarily taking the profit the get from
any sold donations to hire people with serious
life issues, and they will not be spending any
money to change their handling of anything, whether
computers, antiques or whatever of any kind,
but rather keep the basic flow of material
going. Wish they could operate in a different
way.
Even worse, in a town which is the home town
it is sad that there is no used computer or electronic
surplus store with sufficient business and expertise
to take your collectible and sell it, rather than a
Goodwill thrift store. These operations are way
more endangered now days than used book stores,
my other favorite place to get lost in and browse.
Ebay for all its flaws is pretty much where you
get rid of strange junk these days, or recycle it,
unless you are near some operation such as
Gateway Electronics in St. Louis, Mo, or
whatever similar operation may be around.

More spring cleaning.
Item #1
------------
For the past eight years I've been keeping a box that supposedly has a
B&W CRT in it; it was given to me by a retiring engineer and TRS-80
enthusiast. I finally opened the box and confirmed there is a CRT of
some kind it it, although whether or not it is for a trs-80 I haven't
checked.
I have no need for it; anybody willing to pay shipping on it can have
it. It is in great shape and in fact, might be unused. It looks to be
about 12" diagonal.
There are a lot of different markings on the tube, and I'm not sure
which is the most important; in fact, the layout of the markings is such
that I can't always tell what goes with what, but I'll try my best:
RCA Electron Tube
12VCLP4
Model No. 6
EIA 274
KTR131B
Elsewhere it says EIA 1240.
Item #2
---------------
I have a heathkit h89 carcas -- it has been stripped of most valuables,
but it might have a few parts that someone needs to get their h89 going.
Probably the two things that might be of most interest are the CRT and
they keycaps. If you want either of those, or want me to check for any
other bits on it (mounting brackets or whatever), let me know.
It has no floppies and I was told that the electronics had been smoked
via an unfortunate application of the wrong voltages. Still, if you
want to take a chance, I could pull the cards and let you sort out what
might have escaped unharmed.
I think the keyboards were made up by putting keyswitches into a metal
plate then wiring them up in row and column form. A ttl system scanned
the rows and columns until it found a closed switch. The count was then
equal to the value of the character.

FWIW, Newbury terminals were common at Cambridge University in the 1980s
(but were being replaced by BBC micros running a terminal emoulator). I
think they were around at other UK universities too.

When I needed a replacement CRT for a Volker-Craig terminal (it has an
APL cahracter set, which is why I was repairing it), the only way to get
one was to buy a cheap protable TV and remove the CRT from it. Nobody
stocked the CRT on its own.

I have a Newbury terminal somwehre. I forget the model, but it's a later
one with a separate keyboard linked up by a wide ribbon cable (I think
the connections are just the row and column lines of a switch matrix,
there's not much, if any, electronics in the keyboard).
I've not been inside it for 20 years, but I thought there was a
microproceossor in there. I do rememeber a board of TTL incluing some
'181 ALUs, though.

If you don't have web or file server, how do you "give back"?
What's your ratio of upload to download?
