But yeah, I have no definitive evidence, just stuff pointing towards it being related to Topre keyboards.
My current theory is that Topre hired away the guy that did the original design for this particular keyboard switch.
Well, before I think about selling mine, gotta build a USB converter. Maybe after that though.
I will keep my eyes open though, as they pop up from time to time.

to indicate that clock is generated
