Plug : I did put one of my intergrals on ebay item 370112051894
It works fine, only the printheadcable is damaged by corrosion.

No, I am not going top bid on it, I already have a pair...

Argh!. Let me guess... Somebody lefet a cartridge in the printer.
The printhead flexipring in an IPC is longer than that in a normal
Thinkjet due to the layout of the case/PCBs. So you can't just repalce it
with a part from a THinkjet. Probably the easiest thing to do is to use
the Thinkjet cable, then extend it with normal ribbon cable to connect to
the PCB. The power part, between the printer chassis and the PCB,
doesn'tmove during printing, so doesn't need to be flexible.

It wasn't ment for you in the first place ;-) Jos maybe..
You just bought that beautiful HB-IB clock witch I was following until I
could free the money for it :-(
Well I hope the nex one is mine..
I have one working thinkjet the others are having bad cables too, the blody
ink of the cardridges is almost as bad as leaking batteries.
So I'm not going to canabalize that one for the integral.
But if you got spare cables...

You mean that little (and it is smaller than I expected) HP59309A that
arrived here yersterday. You're right, it's beautiful. 4 boards of chips
that I mostly understnad (no microprocessor or anything like that, there
are 3 programemd ROMs on the HPIB interface) plugged into a backplane.
One PCB, of course, is right at the front and carries the user setting
swtiches and display.
This is somewhat OT, but I think several people here have said clock.
Does anyone have the _official_ HP stnadby battery box for it, and can
tell me (a) how many D cells it takes and (b) if there's anything in it
other than D cells.
Well I hope the nex one is mine..
Unless one turns up near here at a very silly BIN price, I am not going
to bit on another one. Of course I am looking for other HP5930xA
insturments at sensivle prices (not found any yet).

I have a fair number of Thinkjets (I think I have at least one of every
model -- -A, -B, -C, -D , -C+ and -P). Some of them, alas, have
flexiprint problmes.
ink of the cardridges is almost as bad as leaking
batteries.
So I'm not going to canabalize that one for the integral.
Sure. The reason for my comment is that Thinkjets are a lot more common
that Integrals, and that all models of THinkjet use the same flexiprint.
So if the new owner of your Integral wants to restore it, it's probably
possible to get any model of Thinkjet with a good flexiprint, transplant
the carriage (or just the flexiprint) into the Integral and then make up
some kludge to connect it to the Logic B PCB. WHat I would probably do is
desolder the flexiprint conenctor from the Logic B PCB and replace it
with an SIL header plug (Molex KK range or similar). Then use normal
ribbon cable to link the socket for that to the original Flexiprint
conenctor, prprboably soldering the latter to a little bit of stripboard.
I'd have to find some way to stop it shorting on the Logic B PCB, the
back of the display module, or the scrrening plate over the Logic B PCB,
but I am sure something could be worked out.
But if you got spare cables...
Alas not.

Inclusive of manual, carrying case, extra memory, RS232 board.
I just need to find a way to recover the MFM disk in the accompaning HP9133D for more
pressing needs, which is the system disk for a Lilith.
I am in fact looking to reducd my herd : altough by classiccmp standards I have few
machines (around 30), I just lack the time for them.
And it is more rewarding to concentrate on very few machines, but then do it properly.
Among the stuff to go :
VT340 ( free ).
Amigo screen 1084 (free).
IBM5155, full loaded, with HD.
The HP Integral.
HP9826 ( lack of useful software ).
HP85 ( just got it, but already tired of it ).
Intel Intellec dual 8" floppy ( would love the Intellec itself, small chance..).
A VT103 / ST412 combo running RT11 ( homemade version, previous owner hacked an 11/23 into
a VT100 ).
a SGI O2 & SW1600 ( nice machine, if slow ).
All located in Switzerland

You can get HP BASIC (which is quite a nice version) and Pascal (looks to
be UCSD-based) from the Australian museum.
I don't know what boot ROM you have. If it's 2.0, then it won't boot from
external drives, but only from the internal 5.25" one. This could be a
problem in getting software. Unfortunately the 3.0 boot ROM is a larger
device and can't (easily) be used on the early version of CPU board.
HP85 ( just got it, but already tired of it ).
Now that I can understand :-). I've never found the HP 80 series of
desktops to be particularly interesting.

But it is very easy to use as instrument controller, or CS/SS80 exerciser..
If you got a 9121 as external drive, tapes are not a real option.
Small OT question do you know how the wires on the HP-65 cardreader head are
soldered (not the ones on the reader pcb)

I am not sure what you are asking. I have (unofficial) schematics of the
HP65, along with almost all other (repairable) HP handhelds. The card
reader had has 5 wires which are soldered to the card reader PCB, but you
say it's not that end you're interested in. Every head I've seen has been
potted in epoxy, so you can't see how the wires are connected at that
end, or indeed resolder them.
What are you trying to do? I might well be able to help.
Incidentally, why is this OT? The HP65 is certainly a classic (pun
intended). It's also, IMHO, a computer (the internal architecture is that
of procrssor + RAM + ROM (albeit the ROM and RAM are on different
(serial) buses; it is user programmable). I can't think of a sensible
definition of computer which includes things like the KIM-1 and excludes
the HP65.

exerciser..
Sue, but I believe CS/80 exerciser software is available for the HP9000/200
machines (which includes the 9826), and that it has much the same
functionality as the HP85 version.
The HP9000/200 machines have (to me) many advantages over the HP85 series,
including an easier-to-use system bus (the HP85 bus is just strange, the
HP9000/200 bus is the 68000 bus with a few more signals), easier to repair
(about the only stnadard chips in an HP85 are the DRAMs, the 9000/200
machines are almost all standard, with a few PALs and ROMs) and a nicer
selection of I/O cards.

I'm repairing/restoring a HP-65 with severe oxidation-damage on the
cardreader pcb and a lose headwire.
This head was filled with white siliconkit so I was able to remove it and
resolder the wire (yellow one). After resoldering,I refilled it with 2k
epoxy glue, terminal resistance seems to be allright for both coils and I'm
now restoring the PCB traces. The head connection explained it self.

Thanks, but it's fixed and working, and I bought 'your' CD a while ago due
time that was very helpfull.
Had to wire all the conductor paths on the cardreader pcb.
But I made notes about the head connections for who wants to dig.
Serial is 1509S07*** but I have another one with the serial 1506S05*** witch
has the head filled with epoxy.

IIRC, the Red and Yellow wires are one head winding (presumably a track
nearer the display end of the calculator), Blue and Orange are the other
winding, and black is a grounded screen.
I think the data format is that a pulse on one track is a '0' bit and a
pulse on the other track is a '1' bit.
