Just a suggestion. Up to about 1960, most (all?)

vacuum tubes. You might want to use that for the initial separation
and specify a different set of parameters for vacuum tubes vs
transistors.
...except when they weren't. (e.g. Univac SS80/SS90--only the clock
generator used tubes--all of the computation was magnetic logic,
diodes and transistors). NEAC 1101/1102 (parametrons). There were
certainly others.
