We just need 3 valued electronics
- percentcer 1y agoon, off, and the other thing
- tyingq 1y agohi-z is one choice. Though I don't know how well that does past a certain speed.
- duskwuff 1y agoIt 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.
- tyingq 1y agoI wasn't pitching it as a solid commercial idea. Just that you can get (perhaps fiddly) three states out into the real world with something cheap that already exists. Like: https://idle-spark.blogspot.com/2015/04/low-cost-n-ary-dacs-using-digital-io.html https://idle-spark.blogspot.com/2015/04/low-cost-n-ary-dacs-...
- ForOldHack 1y agoUsing 8 way quadrature and high-z, you have 16 values packed into 1 quasi-hexalogic gate. May your hydration prove fruitful.

- skissane 1y agoThe Soviets had ternary computers: https://en.wikipedia.org/wiki/Setun https://en.wikipedia.org/wiki/Setun Then they decided to abandon their indigenous technology in favour of copying Western designs
- jojobas 1y agoThere 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.
- nxobject 1y agoConversely, the Soviet Union took the PDP-11 ISA to its limits... including home computers with framebuffers and programmable calculators.
- dale_glass 1y agoSetun apparently used two bits to represent a ternary value, wasting the 4th state.
- bux93 1y agoWe call that 1.58 bit now..
- pif 1y agoIt already exists: True, False and FileNotFound. If you don't believe me, just ask Paula Bean.

- ForOldHack 1y agoBut 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.
- falcor84 1y agoBut, but, what about Strange?
- magicalhippo 1y agoTechnically e would be best IIRC, but hard to implement, so 3 is the closest.
