Hello,
First, thanks to Jay West et al for bringing the list back to life.
I'm looking for a source for the data cable that connects a Commodore
PET, CBM 8032 to a Commodore 4040 dual disk drive. The cable has an
IEEE-488 connector on one end and a female PCB connector on the other.
Any leads would be appreciated. Thanks!
Cheers,

I assume the pun ('leads') is unintentional :-)
I needed such a able about 190years ago, and I couldn't; find oen
anywhere (I suspect they do turn up on E-bay). I ended up making an
adaptor with a 12*2 0.156" pitch edge connector at one and and a 24 pin
microribbon connector at the other. It was only a couple of inches long,
so normal ribbon cable worked fine. In fact the hardest part was making
the jckposts for the microribbon connector, the right ones seem to be
unobtainable over here, so I had to machnin them myself.
And then plug a noraml HPIB cable into that (those I assume you have
plenty of...)
At least the Commodore cable is just a cable. The disk interface 'cable'
that I'm sort-of looking for is the one from an HP9830 to an HP11305
controller. I have the 2 units, but the cable has a significant amount of
electronics (20 ICs or so) at each end.... Unfortunately, due I susepct
in aprt of an idiot who's been writing articles extolling the virtues of
the HP9800s andexplaining how to fix broken ones, the price of such
machines has skyrocketed recently, the point where I know I'll not be
able to afford them. If I ever meet that idiot....

Might I borrow a variant
of that design? I have 12/24 edge connectors
here, and I have proper Centronics 24 pin IEEE connectors. I was
thinking a little PCB with the edge connector on one side and the IEEE
socket on the other.

Sure.
I don;t think I can lay any claim to a 'design' which is electrically
identical to the Commodore cable and which simply consists of matchign up
signal names on the 2 conenctors. So feel free to make it on a PCB, sell
it commerically (I won't care, maybe whoever nowe owns the rights to
Commodore stuff will), etc.
If you decide to sell them, I do urge you to make it abaialbe as a bare
PCB or kit. Solderign that up is very easy, and if the purchaser does it
themselves, they can use whatever solder they like....
Another way to make such an adapter cable is to cut a normal HPIB cable
in half and to wire the cut endes ot edge connectors. You then have 2
Commoodre disk unit cables.

Mirror, mirror on the wall...there were just about 34 readers of the
article, (I know it from the source (the *****)) .
Just wait and the price will go down, it always does..
Do you know if the interface is based on a standard interface like the TTL
or BCD interface ?
I just acquired a book called "the designers guide to interfacing" from HP
written for the HP9800 series.
It describes the 11202A and 11203A interfaces incl. diagrams.

It's potentially rather more than that... And the number of people who
know such repair information exists is consiterably higher...
Just wait and the price will go down, it always does..
Let's hope...

I am almsot sure it is, but it's complicated. It uses the 'DMA' feature
of the 9830 (whcih si not what we'd now call DMA, it's not independant of
the PCU, it's more a way of bringing the memory bus out -- serially -- on
the I/O connecotr).
The 'cable' -- an HP11273 -- has a PCB at each end in a housing that
looks like the normal HP9800 I/O module. One plugs into the back of the
9830, the other plugs into a slot on the front of the 11305 disck
controller. The HP9830 end contains the shift registers to handle the
memory bus, the controlelr end has a 356 word I think it's actually 1K*4)
RAM t oact as a sector buffer.
I think it will all be stnadard ICs. After all, both the 9830 and 11305
are (well, apart from programmed ROMs). The only power line on the 11305
connecotr is +5V, all signals are TTL level.
I hace a pinout of the 11305 conenctor, but that's not really enough to
recreate it.
I just acquired a book called "the designers
guide to interfacing" from HP
written for the HP9800 series.

Yes, I found that in a clearout pile at a place I was studying (the pile
was labelled 'Please take any of this you are interested in', I took about
3/4 of it). I had it long before I had any 9800 machines. In fact that
was a major clue in figuring out the hardware of the 9810 (the 9800 I got
fitst) -- I had much of the I/O slot pinout from that book. Given that, I
could find things like the I/O register, that led to the serial signals
between the CPU sections, and so on.
AFIAK there are no official scheamtics for the disk system though. I have
an 'unofficial set' for the main 11305 unit, and a microcode lisitng for
that. But nothing on the cable (for obvious reasons).

The Toronto Pet User's Group has NOS cables:
http://www.tpug.ca/index.php?option=com_content&view=article&id=73&…
It's under 'Accessories', Item 21 $30 + shipping.
I just picked one up last fall for my SuperPET.

But, in those days, onwe merely needed "able". ?Cables were unnecessary.
