Revision as of 15:12, 3 August 2021
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. 141.101.99.119 00:08, 3 August 2021 (UTC)
(Also, surprised there was no direct "GONDOR" reference. Or maybe that's because it was too obvious?) 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. 172.70.126.174 03:49, 3 August 2021 (UTC)
...So, who's ready to draw up some truth tables? 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... 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 op-amp. Given the subtraction that an op-amp does, the xand gort's truth table probably resembles that of the "implies" operator. Tepples (talk) 04:23, 3 August 2021 (UTC)
the "NORG XORT" is not equivalent to an XOR, as the symbol is round on the right. --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 ? 162.158.129.43 15:12, 3 August 2021 (UTC)
