Interesting. Pre MX Cherry, probably late 70's from the UK plant before they moved to Germany. Went for a decentish price. Nice collector piece.
I missed something similar that was actually made in the original Cherry plant in Chicago not too long ago.

So clean. Think the instuctions/legend is a sticker or some kind of lasered or engraved plate?
My wife I a also push her button . But now she have her button push by a different men. So I buy a keyboard a mechanicale, she a reliable like a Fiat.

Looks like some engraved infill to me, like an award plaque.

so I received this keyboard today and it's pretty much identical to the pictures on http://www.pcwaishe.cn/thread-36933-1-1.html

the caps are all the same profile, smaller than modern cherry caps -- the keyboard is a lot smaller than it looks in some of those photos, not even as wide as the average laptop.

the caps seem like they'd fit on MX switches if the round/stem portion were smaller, or if they were somehow mounted on the switch stems prior to the stems being placed within the switch housing.  in short, they can't simply be pushed onto existing mx switches.  i mounted one on an MY switch by pushing something into the back of the switch to keep the stem in place.

the keyboard housing itself is kind of nice, but it's small and generally incompatible and the switches are terrible, so if anyone is interested in that, feel free to send me a pm.  i've been using the PBT keys from the typewriter i recently purchased, the letters replaced with dyesub PBT and the rest of the board as white on black doubleshots, so i figure a similar setup wouldn't be too bad if i could get these keys onto a modern board.

I wouldn't have expected it to be so compact. I have seen that switch only once before in some portable microsystem like the trs-80/100. Still an intresting collection piece.

wow, so the keyspacing is closer than the normal .75 inch. I notice on the 'site you linked that it's the same size as a Cherry G84-410* very interesting.

Any idea what sort of switch that is, tactile? linear? Looks like a precursor to the M7

they feel like linear switches, but kind of gritty despite not looking that dirty
