Digital Patch Cords

The RI Computer Museum has been looking for some of these for quite a while. This unopened bag was donated today. Now we know what they should look like, so maybe we can find a source for more.

If you're not stuck on OEM parts, banana-jack cables are very common in the modular-synthesizer world and can be had quite cheaply in a variety of lengths/colors.

All of the patch cords that I have found so far were too big to fit in the sockets in the boards. I will measure the sockets and the patch cords and see if there is a modern match.

Yes indeed but the problem is that those are Analog Patch Cords. The computer museum is clearly in need of Digital Patch Cords.

Is this the size needed? https://www.pomonaelectronics.com/products/hardware/miniature-banana-plug-do-it-yourself

And I think they work for BOTH Analog and Digital to boot!

I'm calling a penalty on this post XD

Ouch! These are US$3.41 each at Digikey.

The sockets for the banana jacks measure 0.1 inches, and the jack measures about 0.11 uncompressed. They have "dec" molded into the plastic.

I can easily find 2mm and 4mm jacks, but it looks like I need 2.54mm. I think that the Pomona 2945 that is designed for a 0.104" jack might work, but they cost about $6 each.
