I've created a new thread so I don't distract from JP!'s fine thread "IBM 3741 Data Station / System 3 Barn Find" (keyboards-f2/ibm-system-3-barn-find-t16698.html)
See his thread for a whole bunch of history. The tl;dr for mine is that the original capacitive pcb and electronics:
[*] Used freaky voltages, values, and protocols which I was not sure I was able to build a circuit to support correctly first time.
[*] There was no guarantee that the PCB I had was actually functional when it was pulled from the warehouse. It wasn't labelled as either a new module or an RMA.
Given the uncertainty, I built a thing:
It should arrive sometime around Wednesday of this week - I'll keep you up to date on how successful it was
Assuming 100% success, anyone who wants to can just order it directly from pcbway, I'll add it as a shareable and downloadable project there.

Hi __red__, watching progress in this thread with great interest. I hope to follow your tracks with my own project, eventually, in due course, when time permits, etc...__red__ wrote: ↑Well, it all physically fits together, that that's the first part. Now to flash a new controller and take some measurements!

Oh, do you have pictures of the pcb? I was told that there would be cats.

Very Kubrik 2001 Space Odyssey... Hearing György Ligeti's Lux Aeterna right now...__red__ wrote: ↑
It's a black PCB so hard to see the tracks / pads.

So, I do electronic badges for conferences on off-years and the con organizer asked me last year if we could put a keyboard on it.__red__ wrote: ↑Boogie! All keys are functioning perfectly and have sufficient 'swing'. I have something special for this board... more to come!
So, I showed him the prototype 2018 badge
... and yes, the keyboard was functional.
