Nice picture Henrik,

I have seen this as RAM (magnetic cores) and as ROM (wire pattern) Both used in computers of the 60's and early 70's

Kees, actually this is a wired ROM from an Nixdorf Wanderer build in the mid 60's. Developed by MIT this technique stored the apollo board computer code 🙂

I am stumped Henrik so guessing time.

Was it a clip on device to hold a coffee cup ... before they were built into PCs?

Spoiler

Old joke: Customer calls for repair because they can't get the cup holder to pop-out.

It's definitely a clip-on holder of some sort.

I've seen something similar used to hold grinding tools, where the head is larger than the shaft. The head sits in the cradle, but once you lift up, the shaft can slide through the gap. Writing that made me feel dirty.

So my guess would be tool holder. It's a clip-on so you can move your tool to where you need it when you're working.

Ok got it now.

But rather than just blast out the answer, I will reference and old "You know you have been programming in LV too long when..."

Eliminates the need for ctrl-z.

Ohhhhhhhh... so it clips on to a plate. I was stumped as to why it was at an angle.

Is this an ancient version of the BNC-9920?

No. I am surprised since I thought that would be an easy one.

HInts:

1) The numeric labels for the all of the lights knobs and switches should be a clue.

2) Not shown in the picture is an nine pine D-connector.
