Those old ones I am talking about are these:
not only does it have a metal wire, but the 2 side stems are one piece linked together with a plastic bar too. They are actually pretty nice but couldn't work well with the cylindrical keycaps we are most used to. They basically cause it to bottom out on the stabilizer on actuation and quite harshly. But the very early MX boards still had the M8 style lower profile sphericals so it wasn't a problem.
Oh, INTERESTING. Those, I have not seen. I don't know if they'd count though, since they're M8 rather than MX, truly. They're really nice stabilizers with low profile keycaps, oh gods yes, except for that plastic bar. Remove the plastic bar and yeah you've basically got the early through 1986ish (1987? Later?) PCB mount-clip (5 types! Ha ha ha...)
Recessed nut? The bolt on PCB mounts I have bolt goes through the bottom of the PCB and threads into the supporting clip. I am using some of these type on my GH60. They also lack the dampener on the bottom of the inserts and are probably the most natural feeling type of Cherry stabilizers I have. Though it could just be they are ultra smooth since they were taken from keyboard about 27 years old I am sure they were well broken in.
Proooobably the wrong term for it. Embedded nut? I don't know the right term. The one that had the nut molded into the plastic of the housing though. I've actually never seen straight through bolt-ons, to tell the truth. Didn't think Cherry even made such a thing since the rattle and shake of a keyboard would tend to work a non-embedded nut loose over time, even with threadlocker. Can't remember if it was a Compaq or DEC keyboard I ran into that used the embedded nuts, but they felt incredibly solid and were even more stable than the plate mounts.
The interesting thing about the embedded nut versions I've seen is that they're like the Wyse PC286 ET in that there are multiple lubrication points within the stabilizer itself. Sliding assembly, anchor pivot at wire, and wire retaining clip. Makes them just ridiculously smooth actuating and incredibly stable. Zero walk effect.
Through board clip in style, like costaresque PCB version? I came across some of this once, and they were quite terrible. It wasn't on MX keyboard but something like mei switches maybe.
I wish I could find a picture of them now.. Cherry used to, long ago, offer a through-hole clip-in that's basically the same as the current PCB mounts. But without solder. So instead of the locating pins, you had expansion clips in the same place. The theory of course being that hey, these are easier to install because you just snap them in. Which is not an inaccurate statement. However, yeah, expansion clip style does NOT work so good. They like to break and rattle loose. I've only seen them maybe twice, ever.
But we digress quite a bit, though this would be really,
really fantastic stuff to put in the Wiki. (Who wants to create the page? I can't.) Still wondering though, whether the Duckys are PCB under or Plate over for the stabilizing wire.
