Hi,
Yesterday I recived Thomson To7-70 computer, which is totally dead.
When it's working, on display there are only horizontal color lines,
each of them has witdh of one character. Is ther anybody who can say me
whots's bad. I suppose this can be demaged processor (it's incredibly
hot after 2-3 minuters of working), but I am not sure.
Thanks,
Krzysztof Strzecha

You are right, that is not a Pivot. Unfortunately I am not sure what
it is.
> I got mine for free.
Like I said, "bogus price". I didn't buy it. I didn't even inquire
at the counter. IBM-compatibles (and I think these were fairly so)
aren't real interesting to me even if George Morrow did let his name
get put on 'em. (Though I do have one of the Osborne 3 flavor...a
moment of weakness I guess.)
BTW, speaking of Morrow stuff, I met a guy at the Foothill swap meet
today who was selling a Micro Decision (claimed to be an MD-11 but two
floppies, no hard disk) for $30. I'm not interested -- got two of 'em
that I haven't touched for a while -- but thought someone here might
be. Has software and manuals but I did not see the big stack of
paper-bound manuals that I might expect; the seller said he got it
>from an ex-Morrow employee and it may have been assembled from excess
parts but is functional.
Other stuff found at the Foothill swap:
Sinclair ZX-80. Well, it's in pieces, but board, case top, case bottom,
wall wart...yep, looks like they're all there. $5. First one I've seen
in years so I snagged it.
A couple of S-100 bits. Some HP employees were perturbed by the
prices of quality S-100 gear and so set about designing their own, and
it looks like they got to use HP's printed-circuit production
facilities. Apparently I missed the chassis but got the junk box for
another $5. Included are a pristine blank CPU board of their design,
as well as a couple of S-100 bus terminators. S-100 bus terminators
with the HP logo, whodathunkit? Part number on the board is
7373-60003, and the board comes with helpful instructions in the
traces (no solder mask or silkscreen):
TERMINATOR
THE LAST
BOARD
I think there is a story here, and I want to know more of it than
I got today.
Convergent Tech Workslate, plus printer and serial/parallel box,
condition uncertain. $26. Pricey but if I get it cleaned up and
working it could make a nice desk toy at the office. What sort of
power input do these things want?
Xerox 820 board, socketed but ICs not plugged in. Another project
that the owner lost interest in. $2.
-Frank McConnell
I have the oportunity to aquire an IBM System 36 model 5364 with manuals
and operating disks, all in working condition. My question is, I have never
heard of this system (the 360/370, yes). What can I expect?
Secondly, from the same source, I can get a Compac Portable I XT with
harddrive and memory upgrade, ethernet 3/comm and AST 5250 emulation (some
mainframe terminal?), again all in working condition, but from what I hear,
it's portable in the term that yes, you can lug the entire setup.
Third, for anyone that is interested (you pay shipping, plus maybe a few
extra bucks - whatever you think it's worth) the following are also
available:
10M HD for an IBM 360
Monroe (possible) "bookkeeping machine"
Underwood typewriter (manual)
(unknown) manual adding machine
I'll be hearing more about this stuff on Monday.

I can't tell you much about it, although if it's the machine I am thinking
of, the monitor is actually a separate box that locks in place. It's a
68000-based machine, and has GPIB as standard. SOme of them have a ROM board
containing (I think) HP-basic, while others boot from floppy.

The HP86 is basically an HP85 without the built-in monitor,tape drive,
or printer, but with GPIB as standard. The 9121 is a single-sided version of
the 9122 if that's any help.

Depends on the HDD. Some (such as the ST-225) were el cheapo products
(cheap at the time, compared with more expensive ones -- I have a 1984
adv't, listing ST-225's at $400; ST-251 at $600!)...IBM's Xybec controllers
were slow, tho' I don't know how reliable.
Some ST-506/412 -- e.g., the ST-225 -- drives lacked autopark heads, thus
inviting problems.
This advert appeared in an Australian newsgroup, obviously in error. It
turns out the guy is in Milwaukee, WI.
Perhaps some of you USA people are interested.

There are two flavors of HP 86, the 86A and the 86B.
The 86A does not have the built-in GPIB (aka IEEE-488 aka HP-IB).
Instead it has three connectors on the back. All three look the same,
like Centronics printer connectors but maybe with screw-downs instead
of ears. One is for a cable to a Centronics-ish printer. The other
two are for cables to external 5.25" floppy drives.
The 86B does away with all this and instead has an HP-IB connector.
Re: the 9121: yep, single-sided Sony stiffy drives that hold about
300KB I think. It's been too long and I have forgotten just about
everything except that the single-sided ones never seemed to hold
quite enough (this on HP 150s).
HP was an early adopter of the Sony 3.5" stiffies, back when it was
not clear that the 3.5" format was going to be the winner from the
several sub-5.25" media.
You know how 3.5" drives open the metal slider so they can get at the
medium? The very earliest drives didn't, and the stiffies didn't
spring-load the slider -- it was up to the user to slide the slider
before insertion into and after removal from the drive.
For a while there were goes-either-way stiffies: slider spring-loaded
so that they would close on eject from an auto-open drive, but also
with a catch so you could slide the slider over to the left before
insertion into a non-auto-open drive, then pinch the corner after
removal to release the catch and let the spring pull the slider
closed. That is why those stiffies have the legend "PINCH" near that
corner.
I don't know how pervasive these early drives were. The place where I
worked at the time had a few 1983-dated pieces of equipment (a 9121,
some 9133XVs) that were the auto-open variety.
