Ok, since I intend to use this thing to work on computer related gear older
than 10 years old (my 083 card sorter for example), I'm proclaiming this
inquiry off-limits for random flamage! B^}
Does anyone out there have info (like the tube/switch charts) for an EICO
Model 635 portable tube tester? I've picked up one that is in very good
shape, but is otherwise useless without the charts for switch settings.

I'll be having fun friday...
I get to go argue with a professional junk guy over a KS-10. The company that
owns it wanted it melted down, to protect some confidential data they had on it.
SO, I'm gonna say "None of your data is on the CPU, just the disk packs,
so he can have the packs. There." The drives are 2 RP06es. (Yes, I know I
need 3-phase. Mark says he knows where to get an RM80 or two. Is there
any way around having to have 3-phase for the RPs? I was told they fail every
other 10 minutes, is it even worth it?) It did run TOPS-20, but I'm chasing
after ITS tapes for it. Even if I don't end up getting it, I may get the CPU
cards and backpanels, and then I know someone who has the rest of a KS.
Failing that, if the junk guy gets everything, I know someone else who has
a whole KS, but no operating system. So, one way or another, we're gonna get
a running ITS installation out of this...
Am I supposed to be this nervous?
I've never had to actually argue with a junk guy over a machine, in front of
a buncha suits... (Division heads or something. The actual company is QUITE
large... *hint* *hint*...)

THIS WAS A GOOD ONE. ROFL...
thanks,
emanuel
P.S. Where you got it ? Or you typed it in ?

You can't have mine.
MINDSET was about as you recall. It built in 1984 as a super-multimedia
80186-based PC-compatible (well, mostly-compatible, anyway.) For 1984,
the graphics were superb and it had (IIRC) a video-in connection so you
can use the computer as a character generator/paintbox. I think it was
packed with a low-end cousin to the Time Arts Lumena paint program and
was THE machine for graphic artists. Remember, this was a year and a half
before the Amiga - which, whene IT came out, pretty much took over
Mindset's market.
The Mindset has a unique and quite beautiful white bi-level case design.
So pretty in fact that the Museum of Modern Art put one in their design
collection - the first computer placed in their collections.
Much of the hardware was proprietary - weird memory modules and it also
accepted plug in progrram cartridges.
Mindset didn't last too long as a company. They DID build a second model,
an AT-based machine in charcoal gray. I've seen it once and never read
anything about it
I found my original Mindset last year, complete with a couple of
expansion RAM modules, the boot disks and the paint cartridge.
Like I said, it's gorgeous and you can't have it. Nyah. But - I might
make you a deal on the stereo module!

Sure. The DIL switches are small rectangular objects about 0.4" x 0.7"
and the jumpers... (Sorry, I can rarely resist that :-))
I think this is what you want:
There are 2 layouts, Revision A and Revision C.

Questions:
Does anyone haveSolddering For an idiot projects... something to do with
electronics and soldering
Or for that matter PCB Projects, for an idiot (as above) such as me.
Wanted:
PC-DOS 1.x or MS DOS 1.x/2.x for and XT, with a failing HDD.
Anyone?
Thanks,

Anyone interested in this? I know the guy and he's a very decent person
so you don't have to worry about "getting the wrong thing" I think it's
free anyway. Contact Jeff by driect email at either jarrod95(a)juno.com or

I saw a CDC demo of that once circa 1974, as I recall it was
called "Plato", used a nice orange plasma display, limited
animation, astronomical price. CDC had grandiose plans it would
be used in schools, like every high school in the country could
afford a $2 million CDC 6600 to support it. Kinda sad actually,
once Cray left CDC they didn't have a clue as to what to do
afterwards, the big iron Cyber 6000s went nowhere, the company
wound up running payroll services (the remnants of CDC are now
known as Ceridian, a batch payroll services company).

Time to clean out at least part of my garage, especially in light of the
new arrivals. All offerings are freebies, though it would be nice if I
could get -something- in trade. ;-)
Please bear in mind two things.
1). I cannot ship anything other than the books. The disk and tape drives
are too darn big and heavy, and would require specialized packaging in any
case.
2). Dave Jenner has first pick since he E-mailed me this morning before I
posted the list. I'll post an update if he wants any of the stuff.
With that in mind, I have the following to offer:
1). HP 7974 9-track vertical tape drive, with all mounting hardware. 1600
BPI, Pertec interface, supplied with the hardware to convert it (if
desired) to a GPIB interface. Excellent condition, powers up and loads
fine, have not actually tested it with a working system.
2). (Definitely a freebie!) 83-84 vintage System Industries SMD disk
drive. Spins up, makes lots of noise, don't know if it works. Comes with
mounting rails.
3). Cipher 880 tape drive, dual-density (1600/3200). Condition: Who knows?
Freebie.
4). Books! I've got spare copies of:
DEC's 'Microsystems Handbook' for 1985
DEC's 'Introduction to Minicomputer Networks' vintage 1974
Everex 'Step 386' owner's manual
DEC PDP11 'Programming Card' quick-reference, vintage July 1975
DEC DHV11 Technical Manual.
Any takers?
