I think this was continued into the Lisp-machines, at least the space-cadet kbd had lots of extra qualifiers: the "normal" ctrl, the META which set the 8th bit, another CTRL which set the 9th bit, and a HYPER and SUPER which I can't remember what they set.

And 6-bit bytes (SIXBIT) were used for e.g., file names.
