Onderwerp: Re: Wanted: Commodore CBM disk drive cable
(I
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!
I assume the pun ('leads') is unintentional :-)
I needed such a able about 190years ago, and I couldn't; find oen anywhere 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....

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.
