One reason I prefer the term "Alps Bigfoot" over "AT102-102" is that the latter, just like with the NMB RT101, is ambiguous. It's used both for the Alps SKCL/SKCM standard platform ("Bigfoot") as well as for the rubber dome equivalent.
The one depicted (FCC ID LPZCLARA 101-102) looks like GYIMIDAS101-102, which is a rubber dome keyboard with sliders:

I can't prove that it's not mechanical, only that it's not the expected shape of an
Alps Bigfoot keyboard (Dell AT101, SGI Granite, AX systems etc)
