It reminds me an experimental compuer called Setun, you can read about it here https://en.wikipedia.org/wiki/Setun

Have any one any info on computers based on not bits (0,1) but on trits (-1,0,1)?
Could you answer in any characters (could translate from any).

Current computers all use bit which could be in state of 1 or 0.
But there was idea of a tritr based computer with states of -1, 0 and 1. This will change all logic from ground up (even operations like AND, OR, XOR, IF and others).

Current computers could have IF-then-else because they check for =1 or =0.
But with tritr based logic you could write IF-more-eq-less and get 3 program path selection.
Also it could change how arrays are implemented. Instead of start, index and length any array could point to the middle of selected memory and grow both in +length and -length from staring point (so you could save not only data (+length) but metadata (-length) inside).

It is possible to create emulator of tritr based computer. But there was hardware devices also
(both as "2 bits for 1 tritr" with ordinary transistors and tri-state gates).

There could be totally new "open source" platform for tritr based anything which is completely independent from current bit-based "open source".
Even it could get rid from anything connected to printers (especially "matrix printers" and "contol flows"). No function with name "print", no "\n" (printer new line command), no "\r" (printer carriage return command), no "LPT" port (printer ports), no "COM" ports (some printers use them), no ASCII "control characters" and even no "strings" in any forms (which are also were just a way to use "matrix printers"). Instead there could be "tree of tokens".
