Just finished rebuilding (i.e. take apart, clean, cut new foam, reassemble-- I'm getting good at this!) a Model F AT keyboard from eBay.

I didn't notice until I reassembled it that instead of a "Num Lock" key by the Esc key, it has a "/" key instead. And now that I look more closely, I see the up arrow glyph on the numpad "8" key is smaller, and grayer, than the other three numpad arrows.
I dunno where the weird "/" key could have come from. The color and shape are a perfect match and even the XT version doesn't have this key. Perhaps it's from another Mod F variant?

It could pretty well be from a model M, caps are interchangeable!

If the key on the 8 key is two piece, I bet you its from a model M.

Model F's were used on terminals, with special functions. So that explains no numlock.

Yep, the numpad 8 key is a two-piece. I've contacted the seller to see if the might have the original keys, but it's not really a big deal.
