Are all HHKBs Topre?

[blondie]

I just discovered that HHKBs are Topre. I have had, if I remember correctly, an HHKB lite 2 USB for probably over 20 years. Now it seems that people have strong emotions towards Topre keyboards. But,I don't remember any particular feeling when first starting to type on this keyboard, nor none now. So, I am wondering if this one is a Topre keyboard or not. Or, maybe I just don't have sufficient sensitivity in my fingers (more likely).

IIRC, the early PS/2 HHKBs and the Lite/Lite 2 models all used standard rubber domes. Everything else (with the sole exception of the Studio) is Topre.
