Almost on-topic, except it had zero computing technology -- I rode a
'69 Triumph T100C (single-carb 500cc twin) for several years that had a
combination of metric, SAE, and Whitworth fasteners. IIRC, all the body
parts were metric, the external engine components - covers, jets, etc -
were SAE, and the engine internals were Whitworth. I may have that
swapped around.
I dunno if Whitworth was always _coarse_, but it was always
_irritating_!
