Subject: Mindset Computer Corp Collection for sale

Hi,

  Not sure if Evan posted to the list or not, so just posting:

    Been having some health issues as of late and bills are pouring in faster than money is coming in so I have to make a tough decision and sell my Mindset Computer Corporation Collection.

   I am only selling as a whole as I don't want this collection broken up.  I'm gauging interest, please email at: curt(at)atarimuseum(dot)com

Many have seen quite a lot of my collection as it was on display at a recent VCF East show and one an award.

I have over a 1/2 dozen CPU units, expansion modules, plug in peripheral modules, keyboards, joysticks, mice, tons of software, applications, and games, many are in original boxes and are original disks, I have a huge developers manual, marketing materials, units in boxes, a keyboard in a box, peripheral accessories in boxes (many in never opened/sealed boxes), I have one of the only Mindset software carrying case bags, and much more.   Need to put together a more detailed inventory, but it is extensive.

Mindset was created by the former head of Atari's Home Computer Division who left Atari in 1982 and decided to do a modular, expandable PC-compatible computer system with high end graphics capabilities that Atari wasn't willing to pursue itself.   So he left with a bunch of former Atari marketing and engineers to create the Mindset M1001.

Here are some photo's of a good bit of the collection (monitors are not included):

VCF East is held on the main campus. Last year, on the first day of VCF, we
filled the main campus parking lot and had to send a few people down to the
TIROS lot. But that was due to the inventor of BASIC keynoting our show. :) I
don't expect any speakers quite so impressive this time around. Also there are
other backup lots we could use. There aren't any other shared resources. Perhaps
a few tables/chairs might be in contention but we can easily get more of simple
material goods if needed.

I pasted Evan's reply above as it looks like it went to me personally & not to
the list.

Hi Evan,  OK, I am glad there are no conflicts with the OMARC hamfest. I just
wanted to point it out in case something would be overlooked.  I have never
attended the OMARC hamfest so I was not sure when they set it up.  Since last
year's VCF East was my first, I only had that end of the campus as a reference.

> Welcome to our list. Several MARCHins are hams too. Please introduce yourself.

   To introduce myself, my name is Jeff Galinat and I have been involved with
microcomputers & mainframe computers since 1977. I built an IMSAI 8080 during
IBM basic training in Chicago.  I bought it to & from home a few boards at a
time until all the soldering was done. I soldered 1600 of the 2200 pin backplane
(22 slot version)in one night & was amazed that it worked.  I purchased the
NorthStar floppy disk system shortly after and had a good deal of fun with it
until I sold it in the early 80's.
  I was an IBM customer engineer for 17 years, starting with S/360 I/O link 2540
reader/punches, 1403 printers and similar equipment.  I became CPU trained with
the 4300 line and was then trained on the large water cooled machines like the
308x, 3090, and 9021 CPUs.  I left in 1994 as I was tired of weekend work & call
outs from home.
   I have recently rekindled my interest in vintage microcomputers and plan on
putting together an S-100 system or 2, with one being mostly home-brewed.  This
may be a pipe dream but I think I can do it.  I am still hashing out details in
my head.  In the interest of getting reacquainted with some 8 bit hardware, Last
year I built Briel Altair 8800 Micro and MicroKIM kits to play with and then
purchased an 1802 Membership card kit at VCF East from Herb Johnson.  I met Herb
& Bill Degnan at the Trenton Computer Fest last March so I have met at least 2
members. As a final note, I have been selling in the TCF flea market for 36
years so I may have met other member along the way.
Sorry, I am l not usually so long winded but I wanted to give you a complete
history.
Jeff

ekoblentz
Send Email Send Email
 
Here's the latest on the museum power situation, based on Fred's report at the
InfoAge staff meeting tonight. (For list newbs: Fred is the director of InfoAge,
where our computer museum co-resides along with several other groups' museums.)

He expects the transformer that we need to cost around 40-50K installed. More
assessments are still arriving.

This might be covered under the town's insurance because they own the facility.

InfoAge's board may have other ways to get the money quickly.

FEMA, the power company, and local pols (and possibly our state/federal-level
pols) may be involved.

A major NJ university is seeing if it has an appropriate transformer that it
could just give to InfoAge.

The actual work would only take a week or two by licensed professionals.

While we're at it, InfoAge will eliminate some of obsolete electrical
infrastructure on campus that's been sucking money.

So that is all that I know. There is no timeline. Some people are expressing
confidence that it'll be solved and back to normal within a few weeks or maybe a
month or two. Others are more pessimistic, or realistic, depending on who's
asked.  :)  Nobody truly knows.

Someone suggested InfoAge build a windmill, or get wave/tidal power from the
adjacent river, so that we'd have a compelling energy exhibit and be more
self-sufficient......

Meanwhile we in MARCH will continue spending most Sundays working in our storage
area. We're making good use of the downtime.

Other groups such as IXR are lucky because they're in standalone buildings that
are easily powered by small generators. MARCH's museum is in a large building
that cannot be simply converted.

Oh, that reminds me of another thing. A suggestion was made that while InfoAge
is changing transformers anyhow, it might as well invest in switches (I forget
the technical term for what kind of switches) which would allow easy conversion
to generators during any future power outages. Everyone liked that idea.

MARCH officers are considering VCF East backup plans, because we don't know if
the power situation will impact us at that time. We will probably make an
announcement about that in the next few days. Stay tuned....

    Wow.  I cannot even quantify the suckage. :-(

    These are called "transfer switches".  They are expensive.

    My generator is still available here, should you want more wattage.

Debut is Jan. 30 in primetime. I think 10pm. Google it.

It has MARCH terminals for the KGB office, Jeff B.'s PET (among other PETs) in
the spy's travel agency (that's their disguise), and InfoAge desks but I don't
know where. They bought computers elsewhere for the FBI set.

I would err on the pessimistic side, and plan on moving VCFeast
further into the year (just keep in mind other major events, like MIT
Flea, the Sussex hamfest, various other big days).

It may take a long time to get a new transformer. I was just at a
storage place in Changebridge, next to a utility storage yard - and
the place has been raped of every transformer and gizmo, and is now a
big parking lot. I bet this is a common site all over the Northeast,
probably well into the Midwest. I would also bet that the companies
that make transformers are completely slammed with backorders. A small
museum probably does not have the pull that a power-sucking warehouse
or factory has, and they may make Infoage wait. Keep in ming that
transformers will continue to fail over the next year or so, as the
ones weakened by the storm give up.

You may want to call up some of the transformer companies and ask what
a realistic leadtime might be for the product Infoage needs.

FWIW, the transformer outside my home which blew up during Sandy has not
yet been replaced as well as others in the area.  I think we are all run-

Send Email Send Email
 
I'm soliciting opinions from the group about my choice of exhibit for this
year's VCF-E.  I had initially been talking to Dave McGuire and some others
about bringing a VAX 4000/300 and participating in a VAX cluster, but I'm
considering other options.  For instance, I've had at least two people request
that I bring my HP mini again.  While I dislike the idea of rehashing an
exhibit, the HP 2109E system is now more fully configured, with a second 264x
terminal and a 9-track tape drive and cabinet.  Maybe I can get the 8" floppy
drives working.

    The real reason I'm leaning away from the VAX is that I'm not very familiar
with it, and I'm not sure I have enough time between now and VCF to get up to
speed.  At least with the HP, most of the work is done.  Yes, I realize the
amount of DEC brainpower that will be present to assist, but I like to feel
useful, too. :-)

    Of course, there are always the Kaypros, TRS-80s, Morrow and NorthStar
systems yet to be exhibited.  I like to be different, though.

    So, what do you think?

   Then I'll bring an additional VAX, similar to yours, and set it up in
your exhibit area.  That way, you can have the best of both worlds and
won't miss out on any of the fun.  I'll be in a truck anyway.  What do

   I'd welcome the 2109E, and wouldn't consider it a rehash due to its
recent expansion.  Multiple terminals and the 9-track drive make it a
VERY different system, exhibit-wise, and I think showing the evolution
of the system as you build it up is also good.

We'll have to collaborate with Dan Lieb for that:
the shipwreck museum collabortes with the
Pine Creek Railroad, so a steam locomotive is POSSIBLE
but we'd have to put it on a treadmill to generate electricity.

I'm unusure if we can get samples from the

I have three.

MOS integrated circuits 7/76
linear integrated circuits 1973
TTL Databook 1976

Most National chips start with LM or DM (AH, AM, MM, ... etc)

Not one chip in the three databooks (mid 70's) has any chips that start
with "NCR".  What else is on the chips?

NCR is National Cash Register. The purple chips look very mid-1970s
Motorola. They probably made them for NCR.

Replying to myself.  I could not find anything in the Motorola books, but I
am guessing now that these are equivalent part numbers, not original
Motorola part numbers.  Sorry I can't help.
