Are there any identifying marks on the barrel plate? My ADAM keyboard's plate had "JFK-4004-A" hidden away on it.

The thing that sticks out about the JFK domes, to me at least, are those 4 notches on the bottom of the dome, as shown in this picture I took of the ADAM domes a while ago: https://pbs.twimg.com/media/EK-r5iwX0AA6_KE?format=jpg&name=4096x4096 I've seen that particular dome design in several other pl...

Usually when I see "made in Thailand" on a rubber-dome board of that vintage, I would think NMB (since practically all of their rubber-dome boards were made there), but this one seems unusually cheap.

That's super weird considering the Jelco switches are a lot taller than these domes, odd choice to pair them with these caps then and doesn't help at all to explain the relation of these caps/switches with previous silver reed stuff. Never heard of those switches before either but I suppose that's ...

I did some looking into this (including buying one of the bare, Archer-branded ADAM keyboard mechanisms that show up on eBay from time to time), and it looks like whoever made the ADAM keyboard also made the TRS-80 Color Computer I keyboard c. 1980.
