I suspect people really care; they just don't have good information on what's going on. EG is the IBM Model Z some random BS printed by some joker? Or is it an unusual and proprietary variant that doesn't work with Soarer converter? (Remember Orihalcon bought a bunch of new Lynx keyboards only to discover that they could only work with one version of Soarer.) It would be very curious if there were some versions of capacitative boards that had some unique properties.
