Were there ever plans published, or kits, or a machine made, for a noughts-and-crosses computer game which did not use electronics – using only wire, an electricity source, and light bulbs ?
- . A Playing against the computer game .
- . I'm looking for the most optimal solid-state designs
- . Machines containing things like electromagnetic relays / solenoids, are not accepted as answers, since I'm looking for alternate computer logic .
- . Machines containing multi-contact-switches would qualify, although, of course I'm also looking for the most optimal solid-state designs, which would decrease these to minimal amounts, perhaps at the cost of containing more wiring.
- . Machines containing a rotating component, like How to build a working digital computer, are not preferred answers, but they would be interesting to know about, if they only use wire, an electricity source, and light bulbs ?
Why I think one may have existed, and how it could have functioned .
It would use memory-boards, to compare the situation on the playing-board, to match it to one of the memory-boards, so when a memory-board is matched, it lights up a new square on the playing-board as the computer's next move.
Each memory-board would just be a length of wire, with gaps at certain positions to represent noughts or crosses (it may require separate memory-boards, one for noughts, one for crosses), and both sides of the gap wired up to a square on the playing-board, so when the human plugs in a piece, it closes/completes that part of the wire to allow electricity to flow. (so each square on the playing-board, would be wired up to lots of memory-boards).
- Maybe, to significantly reduce the amount of memory-boards, some sort of board rotation for matching), could be used, simply using wiring.
- NOTE - An innovation ( a computing / logic / circuit innovation ) would be, that for the human player , each plug-in-piece, would be numbered from 1st move to last move, each one of these plug-in-pieces would be of a different length to reach down to activate a different move-number/platform/circuit of the game.
( Or, of course, the plug-in-piece could have multi-contact-switches, varying for the move number ).
I wonder if theories used in Multiway switching / Switching circuit theory may be helpful. - I don't know if such a machine could work, I have not fully thought through all the details.
- Anyone trying to visualize if this would work, use a 2x2 board.
(Note – for a computer, where a person simply plays against another person, it would be very simple for a machine not using any electronics, just using wire, electricity-source, and light-bulbs, to simply detect a win, when an entire row has noughts or crosses. I assume the original computer battleships game worked like that, so that's not the question in this post.)
Also, my other question, which they erased / closed Could you make a calculator without electronics ( using only, wire, electricity-source, and light-bulbs )? , had a useful innovation regarding the 'carry' in a binary calculation, it could be relevant for this question also.
( Quote "An innovation, could be plug-in-pieces/electrical-contact-pieces ( acting like switches ) that would be of a different length ( depending on what part of a number they are ) to reach down to activate a different circuit of the calculation ( useful for the 'carry' of a binary calculation ). ( Or, of course, the plug-in-piece could have multi-contact-switches, depending on what part of a number they are )."
- NOTE. - What if this innovation, detailed above, regarding the 'carry' of a binary calculation, could lead to making an arithmetic-logic-unit which contains no transistors ( or even to other integrated-circuits not containing transistors ), by erasing that question there is no proof that I may have invented it.
