| The Soviets had ternary computers: https://en.wikipedia.org/wiki/Setun Then they decided to abandon their indigenous technology in favour of copying Western designs |
| |
| ▲ | jojobas 6 days ago | parent | next [-] | | There was a very good reasons for it, indigenous designs were obsolete by the time they left the drawing boards and countless design bureaus cost stupid amounts of money while producing dozens of incompatible computers. By the time they decided to adopt ES EVM they lagged by some 5 years and continued to lag further behind. | | |

| It already exists: True, False and FileNotFound. If you don't believe me, just ask Paula Bean. |

| But with 5 valued electronics, Up, down, left, right and charm... You could have the equivalent of 45-bit numbers ( 44 + parity ).
And you could have the operands of two 15 bit numbers and their result encoded in 9 quint-bits or quits. Go pro or go home. |

| ▲ | tyingq 6 days ago | parent | prev | next [-] | | hi-z is one choice. Though I don't know how well that does past a certain speed. | | |
| ▲ | duskwuff 6 days ago | parent | next [-] | | It works poorly at any speed. Hi-Z is an undriven signal, not a specific level, so voltage-driven logic like (C)MOS can't distinguish it from an input that's whatever that signal happens to be floating at. In current-driven logic like TTL or ECL, it's completely equivalent to a lack of current. | | | |
| ▲ | ForOldHack 6 days ago | parent | prev [-] | | Using 8 way quadrature and high-z, you have 16 values packed into 1 quasi-hexalogic gate. May your hydration prove fruitful. |

| Technically e would be best IIRC, but hard to implement, so 3 is the closest. |
