* I also picked up an HP-IB looking cable with a
Commodore
logo on it. If I remember correctly, these were used to connect
peripherals to some old Commodore systems (I don't really follow
them). It looks like it is totally unused in original bag. If anyone
wants it, let me know. I pretty much grabbed it with the express
purpose of offering it to the list, as old micros aren't really my
thing. It's free as well for the price of shipping, I guess.
Well, a very kind soul has informed me that this cable is a quasi
rare item used to connect peripherals to Commodore PET systems, and
apparently that they are worth a bit of money ($50-80).
So, before I just end up giving this thing away to the person
lucky enough to nail me on a "first come, first serve" basis, does
anyone have any ideas on how to make this part available to anyone
who may be interested in it in an at least marginally equitable
fashion (if multiple people are interested)?
If nobody's interested, then I'll just hang onto the thing -- I'm
sure somebody might run into the need for one sometime in the
future. Otherwise, if you want it, just shoot me an e-mail and let
me know -- i'll wait a little while and see how many people are
interested, and we can go from there...
I don't mean to offend anyone by kind of retracting my original
offer -- I just want to give everyone who may be interested in
the part an equal chance at grabbing it irrespective of "luck of
getting to me first". I'm still not looking for a fortune here --
if anyone wants to cover my costs on the cable (I paid $5), that
would be cool, if not, and you're the only person interested,
well, I still wouldn't be adverse to just handing the thing
out.
Kind regards,
Sean

It _is_ an HP-IB cable. The "some old Commodore systems" were called
PETs. The printers and disks, etc., were GPIB devices (General Purpose
Interface Bus - the non-HP name for IEEE-488). I even have an external
serial port from a third-party - there's a UART and some logic inside
to convert back and forth. To me, at least, slowness aside, it's one
of the coolest features of the PET - you can hook up HP plotters
and laboratory equipment, etc. The only problem was back in the day
when PETs roamed the earth, the instruments that also had HP-IB interfaces
cost as much as the PET itself. It was fun to play with the expensive
toys in Physics Lab, though.
Well, a very kind soul has informed me that this cable
is a quasi
rare item used to connect peripherals to Commodore PET systems, and
apparently that they are worth a bit of money ($50-80).
I would dispute the quasi-rare label. You can still buy as many as
you want, not from Commodore, but recently manufactured, for, as you
say, the $50 range from catalogs, or, as I do, at hamfests, etc.
if anyone wants to cover my costs on the cable (I paid
$5), that

I'll say this... you did not overpay for it. Personally, my limit
at hamfests is about $15. If I see a $10 cable, I might buy it. If
it's $20, it sits where I found it.

The same seems to apply to the "genuine" HPIB (from HP) cables. They cost
$50-$80 when you want to buy one right now, but if you buy them at swap meets,
surplus, etc, you can get them for MUCH less.
I once bought a pair of 2-meter and a 3-meter cable, genuine HP stock, for
$3.95 for the lot at a local thrift store.

So you need a specical cable -- edge connector to Blue
Ribbon male/female
thingy to link the first peripheral to the PET. And then conventional
GPIB cables (Blue Ribbon male/femaly thingies on each end) to link the
other peripherals up.
Tony,
Thanks for that bit of info...I didn't know that the cable
going from the PET to the peripheral was different than the standard.
Thankfully I've got the Commodore cable to go from the PET to the
4040 disk drive and a generic cable to daisychain on to whatever else.

Damn Jeff, you got a Commodore PET 2001?? I used to sell those beasts back in
'79. Right along with Sol-20s.

It was stashed out of sight when you were over here....I need
to take it apart as it seems to have gotten shaken up a little during
the move and is no longer displaying correctly. It's one of the
later ones with the plastic case.

I've got a couple of cables with the heads broken off the strain relief
screws. I guess one of these days I'll have to replicate them.. Would you do
that in stainless or in (after=the-fact) blued 4320, Tony?

There are 2 types of Commodore GPIB cable. The PETs didn't have the
conventional 24 pin Blue Ribbon connector, they had a card edge (OK, the
8032SK is the exception, it does have the Blue Ribbon connector). The
peripherals all have the Blue Ribbon connector.
So you need a specical cable -- edge connector to Blue Ribbon male/female
thingy to link the first peripheral to the PET. And then conventional
GPIB cables (Blue Ribbon male/femaly thingies on each end) to link the
other peripherals up.
The 'conventional GPIB' cables are AFAIK still being made. I still see
new test equipment with that interface, so I assume somebody is still
making cables for it.
The special 'first cable' is not that easy to find. I needed one for my
P500, and I ended up having to make an adapter with an edge connector on
one end and a 24 pin Blue Ribbon socket [1] on the other. I can then link
normal GPIB cables up to that.
[1] Have you tried getting the screwdown posts for GPIB sockets? Nobody
seems to sell them. After a lot of looking, I ended up buyingf some
stainless steel rod and an M3.5 tap....

Blued screw jacks indicate a metric thread, while the (rare) crome finished
screws have an english thread, don't mix and match! You'll strip the threads
baddly.

True... I wasn't thinking of the System cable.
