I recall programming a Univac 1108 at the Univ of Wisconsin in the late 1960s and early 1970s. It was run by the statistics department.

IIRC the 6 bit character set may have been called 'SDF', but I don't recall what that stood for. However, 6 of them would fit perfectly in the 36 bit word that the 1108 had. There were some instructions (or addressing modes) that would pick apart such a character 'string'.

(we also had a PDP-8, a Datacraft machine, and a Burroughs 5500 or 6500 (stack oriented architecture on Burroughs)
