As someone has just Transcripted basically almost all the fine detail I had planned to entable in the Explanation, I shall not now create repetition. Though I had a little more description to the NORXONDOR GOGONAX, in particular, to reference bidirectional (antiparallel) diode pairings (e.g. an LED assembly that glows a different hue depending upon the applied current bias) as probable inspiration, and that latched Flip-Flops surely inspired some part of the Frankensteinian gate-types, too.

(Also, surprised there was no direct "GONDOR" reference. Or maybe that's because it was ''too'' obvious?) [[Special:Contributions/141.101.99.211|141.101.99.211]] 00:12, 3 August 2021 (UTC)

: I was also missing a "GONDOR" reference, and all the X's also made me think XEHANORT. [[Special:Contributions/172.70.126.174|172.70.126.174]] 03:49, 3 August 2021 (UTC)

: Never mind GONDOR, surely "The black GATES of MORDOR" should feature heavily? 11:45, 6 August 2021 (UTC)

...So, who's ready to draw up some truth tables? [[Special:Contributions/172.70.126.211|172.70.126.211]] 01:22, 3 August 2021 (UTC)

I can't get the lines in the bitwise-operation example to align properly; the first one is indented a tad.  Can someone please fix that? Thanks... [[User:BunsenH|BunsenH]] ([[User talk:BunsenH|talk]]) 04:11, 3 August 2021 (UTC)

The symbol for norx gate (1-input OR, two outputs) I'd read as a noninverting buffer to increase another gate's usable fan-out. Xand gort resembles the symbol for an [[wikipedia:Operational amplifier|op-amp]]. Given the subtraction that an op-amp does, the xand gort's truth table probably resembles that of the [[wikipedia:Material conditional|"implies" operator]].

the "NORG XORT" is not equivalent to an XOR, as the symbol is round on the right. --[[Special:Contributions/141.101.69.186|141.101.69.186]] 06:39, 3 August 2021 (UTC)

Right, "NORG XORT" would be a XNAND with inverted inputs, though I don't know what the logic table from a XAND or XNAND gate would look like. If De Morgan applies to XAND/XOR the same way as with AND/OR, would a "NORG XORT" then be equivalent to a XOR ? [[Special:Contributions/162.158.129.43|162.158.129.43]] 15:12, 3 August 2021 (UTC)
:: I think it is specifically a hybrid between XOR and NAND.  The left edge is curved like OR, and the right edge curved like AND.  I did spend some time thinking about XAND, though.  One of my ideas was a >2-input AND that is only true if exactly 2 inputs are true.  I wonder what qubit gates are like.

;Logic Gates
It seems to me that their ought to be 16 possible logic gates.  Although some would ignore one or both inputs.  [[User:Algr|Algr]] ([[User talk:Algr|talk]]) 07:18, 3 August 2021 (UTC)
:Yes. The 74181 4-bit arithmetic logic chip implements all 16 possible binary logic operations. See https://en.m.wikipedia.org/wiki/74181 [[Special:Contributions/162.158.94.253|162.158.94.253]] 07:34, 3 August 2021 (UTC)
:: It doesn't say the names of the various gates.  On my list I made up a few, like "Only B" that only returns true if B is true and A isn't.  Are their real names for this? [[User:Algr|Algr]] ([[User talk:Algr|talk]]) 18:57, 3 August 2021 (UTC)
::: I could suggest "Unless" (as in 'B unless A', or maybe to counterpart 'A unless B' with standard order of operands, 'A disallows B'). Though the partially composite construct '!A && B' would be easier to grasp by those already handling logic statements, I think.

:::: So '''"Only B"''' is called '''"Converse nonimplication"'''?!  Maybe I'm the ''only'' logical person. [[User:Algr|Algr]] ([[User talk:Algr|talk]]) 06:30, 4 August 2021 (UTC)
:As Randall drew gates with two outputs, these would have 256 (16^2) possible functions [[Special:Contributions/162.158.94.252|162.158.94.252]] 15:15, 3 August 2021 (UTC)
:: That couldn't logically be anything but two logic gates sharing the same input. [[User:Algr|Algr]] ([[User talk:Algr|talk]])

there should be a category of comics where it starts out like a normal list and gets weirder and weirder like [[2070:_Trig_Identities|Trig Identities]] [[Special:Contributions/172.70.34.164|172.70.34.164]] 18:53, 3 August 2021 (UTC)Bumpf

What, no IMPLIES gate? I actually used this once to implement a NOT operation in a database see search. [[User:Joem5636|Joem5636]] ([[User talk:Joem5636|talk]]) 11:00, 4 August 2021 (UTC)
: Yeah, neither IMPLY nor NIMPLY, the only asymmetric gates where the inputs can't be arbitrarily swapped. IMPLY: 0,0->1; 0,1->1; 1,0->0, 1,1->1; NIMPLY 0,0->0; 0,1->0; 1,0->1, 1,1->0  [[Special:Contributions/162.158.91.2|162.158.91.2]] 15:25, 16 August 2021 (UTC)


It appears to me that the new gate names are just taken from the letters of the original gate names: NAND, NOR, XOR,and GATE. They're just stuck together in ways that tickled the creator's fancy. OK, tha's already been noted. [[Special:Contributions/172.70.130.108|172.70.130.108]] 11:11, 4 August 2021 (UTC) [[Special:Contributions/108.162.216.239|108.162.216.239]] 11:13, 4 August 2021 (UTC)

Unlike professional devs, I don't have a multiocular O key on my keyboard, so I verbosely write out __norxondor_gorgonax_bitwise everywhere in my code when writing kernel modules :-/ [[Special:Contributions/172.70.110.44|172.70.110.44]] 22:57, 4 August 2021 (UTC)

Is it just me, or did the first four gates sound Seussy to someone else? "AND gate, OR gate, NOT gate, NOR gate." [[User:GreatWyrmGold|GreatWyrmGold]] ([[User talk:GreatWyrmGold|talk]]) 04:10, 5 August 2021 (UTC)

there should be a category of comics that start out with obvious/known things and get weirder and weirder like this. the only other one i can think off the top of my head is [[2070:_Trig_Identities|2070: Trig Identities]] though [[Special:Contributions/172.68.65.221|172.68.65.221]] 01:39, 13 August 2021 (UTC)Bumpf
