Someone wrote on the diagram: Nixon | FET. Economic Drain. Water Gate, Unimpeachable Source. | jsjddbbwj wrote: | Thank you, very valuable comment. | throwanem wrote: | Yes, it is.

They had their own | nonstandard symbol for bipolar transistors too, three stacked | boxes labeled N, P, N, with a triangle on the emitter. (See | page 1-4 of the document above.) IBM also had their own logic | gate symbols: an OR gate looked like an AND gate, and an AND | gate looked like an op amp. | | I came across the FET joke while looking up IBM transistor | symbols in response to TubeTime's thread on the history of | transistor symbols (which is an interesting thread you should | read): | https://twitter.com/TubeTimeUS/status/1249023089528078337 | my_usernam3 wrote: | Why is that? | | My "IBM is evil" bias leads me to guess they wanted to make | their own standard that people started using.

The standards didn't exist at the beginning, so | different companies used different things. IBM also had | historical baggage, wanting to stay consistent over time. | In some ways IBM's symbols were better, for instance | making NPN vs PNP obvious. Finally, IBM was big enough | that they could do their own thing and train their own | people. | amelius wrote: | Indeed an interestng thread, thanks! | DanBC wrote: | I think it's a logic diagram, not an electrical symbol. | | For anyone looking for an explanation of the newer symbol, | this is a nice source: https://www.petervis.com/electronics/M | OSFET_Symbol/MOSFET_Sy... | | Arrows were used in 1975, see page 57: https://www.noao.edu/e | ts/Mechanical/Policies/ANSI%20Y32.2-19... | pachico wrote: | Who knows the amount of jokes being written now given the current | political landscape... | CalChris wrote: | I found an obscure dirty joke on p. 46 of the _Mac OS X Assembler | Guide._ [1] .fill 69,4,0xfeadface | put out 69 | 0xfeadface's | | [1] | http://personal.denison.edu/~bressoud/cs281-s07/Assembler.pd... | Zenst wrote: | AIX used to (probably still does) use DEADBEEF as a hex value | to clear memory out. ___________________________________________________________________ (page generated 2020-04-12 23:00 UTC)
