No, the IIc, and naturally it was removed when the
expansion ram card went in. didn't you save it?

I never took one out when I first put the expansion card in. Even the installation manual from Applied Engineering never mentioned anything about a keyboard brace. Hmm...

If there was one, perhaps the technician at Upstate Computer Shop removed it when s/he did the motherboard swap out back in 1986 (replacing the non-UniDisk-ified board with a UniDisk-ified one).

What I do have is a keyboard assembly made thusly:
- the keys are individually mounted in holes stamped into a full-size piece steel plate of about 1/16" thick, with half of the body of the keys protruding through the plate, - the keys' contacts are soldered into a circuit board, which acts as the "bottom" of the assembly.

The thickness of this entire assembly is almost 3/4". It is quite hefty, and if I say so, quite sturdy. I cannot flex it.

The information etched onto the board is: "ALPS 12KC538A" (located near the ribbon connector) and "Apple Computer Inc. SP-2194V-0" (located underneath but across the board from the ALPS etching). There is a label affixed to the board with "P/N:699-0065 59R 09971" printed on it.

Like I said, unless the Upstate Computer technician removed and kept it, I don't have a keyboard brace. But I wouldn't think a part manufactured with heavy gauge steel would need one. :)
