I recall trying to find information on these when doing research into the most infamous bad keyboard of all time abour 2-3 years ago. I only found one detailed description of its internals which described it as a rubber dome keyboard with carbon contacts over a PCB, and this is the first time I've seen pictures of the insides. The pictures also confirm what I read about how the "improved" keyboard was the same as the original, but with more conventional keys instead of the 'chiclets'

The latter picture sort of reminds me of the underside of the top part of the IBM M4.
