Is this a tough find or is there a simple solution to pick up one of these cables? I suspect it will be a pain to find.

I need one and I'm happy to pay or trade.
 
Don't own a PET so I don't know for sure, but if the linked item is the correct cable, they're all over eBay. It may help to search for GPIB, HPIB, and/or HP-IB.
 
That is not the cable you need.

But, you can make one if you buy that cable, and the necessary card-edge connector, which is pretty common on eBay. Look for one for a C64 User Port. It's the same connector.

Buy two card edge connectors, cut the cable in half and make two cables. Sell one on eBay.

I was lucky to find a cable on eBay that was for a different machine, but, the same exact cable. I don't recall what that machine was, but it is a moot point because it was rarer than a PET.
 
I wonder why I never thought to make something like that. It makes MUCH more sense than the adapter cable.

I also wonder why he doesn't key them. A drop of glue and a small cutoff of PCB does the trick.

His prices are too good.
 
Well, Jim has limited time, so that's basically why. If someone can direct me to a store of the little plastic inserts they used to use for keys, I'll buy and have one of my kids install :)

I make mine from PCB scraps. I got the idea from a connector I had that clearly had PCB-like material (not plated) glued in for keys.

Granted, it's not the easiest thing to cut the right size piece of unplated PCB. I usually cut them reasonably close with a cutoff wheel in a die grinder (think "Dremel" [mine is not]) and then I finish them to size on a disc sander. Mind you, I could probably do both operations with the die grinder if I didn't have the disc sander ready to go. Being a lot more careful with the cutoff wheel, I could eliminate the second operation, too, but in my case it's quicker to do both operations.

If you thought you could use 100, I'd try to quote a 100 piece order, and see if my tooling costs would be feasible. I could probably rig up a tile cutting saw (or something like one) with some fences for quickly cutting right to size.
 
Wow! $0.47 is a bit steep for a couple of cubic mm of plastic.

I key all my edge connectors with little bits of plastic cut from an old plastic folder. I guess the plastic is about 0.3 mm thick and it's cut into peices about 3 x 7 mm in size which fit into the gap. Sometimes they are a bit loose but i just solve this with a tiny blob of cyanoacrylate glue.

On an off-topic note, having keyed connectors doesn't always help though. A couple of years ago I got a pre-production plus/4 that had the keys in the user port cut the wrong way round, which meant that when I connected a properly keyed diagnostic plug, it sent 9V AC into all sorts of places it shouldn't have been and fried every RAM chip on the board. Thankfully the TED and CPU survived...

I am happy to order 100 if the price can be made reasonable. I see Future Electronics has a version for $.47 a piece:

Hello Jim,

I'll see what I can come up with. I hope you're not in a hurry though, I may not get to it for a while. :(
