I recently(-ish) caught a video on the Setun computer – a Soviet era ternary computer (using three-valued ternary logic instead of two-valued binary) – the whole computer worked on balanced ternary (-1, 0, +1) except for its slow “RAM” – the fast “RAM” was ferrite core, but, in the interests of cost, the slow “RAM” was magnetic drum (or two magnetic tapes wired in tandem) that stored each trit using two bits in binary-coded-ternary (BCT) – for all the advantages of ternary, the catch seems to be that math operations run faster using BCT than pure ternary
