74LS47

@Spitzak and 9291Sam: The revert (diff) does not seem desirable to me. Is there some text in the reference (a long pdf spec of the 74LS47) which verifies that the chip was designed to only produce 0–9 correctly? It's WP:BLUESKY obvious that a 7-segment display cannot show A–F other than with made-up symbols. What is the problem with the new text? Johnuniq (talk) 03:41, 18 June 2022 (UTC)

Lots of decoder chips show A-F in 7-segment displays (abCdEF). Yea you have to use both lower and upper case so that solution is dealing with "the limitations of 7-segment displays" and doing much better than this chip. The referenced documentation is not giving any reason behind the results shown, the fact that they are showing them just means they are documenting the behavior, not that it was "designed".

In any case my main complaint was the claim that these patterns are "due to the limitations of 7-segments" when it is quite obvious that much better results are possible within these limitations. Unless there is a reference it is pretty much impossible to say anything about the patterns, perhaps "seemingly random, it is unknown if the chip designers purposely modified the circuit to produce these patterns, or if they are just the random result of a circuit designed to produce the digits 0-9 correctly".Spitzak (talk) 17:22, 20 June 2022 (UTC)

Excellent article

In my opinion, this article is of extremely high quality. I am a software developer, and I could not do better. Thank you everyone for your work on this. 38.158.133.244 (talk) 04:34, 10 August 2023 (UTC)

Sexadecimal section needed

I recently learned about a variant on hexadecimal called sexadecimal from Dave's Garage on YouTube. It uses the symbols K S N J F L instead of the usual A B C D E F for the digits 10–15. Sexadecimal redirects to Hexadecimal, but the former isn't really discussed on the latter. The unusual K S N J F L sequence is also mentioned on the pages for ORDVAC AND BRLESC, but without much discussion. More info — or perhaps even a new section on this page — would be nice. Dave's Garage managed to fill 22 minutes on this obscure topic. Elert (talk) 21:43, 10 August 2023 (UTC)

From what I can tell, from Dave's video, he just made up the term "sexadecimal" as a cute alternative to "hexadecimal", and the word "sexadecimal" is not actually the word that was officially used for KSNJFL. -- leuce (talk) 15:05, 22 August 2023 (UTC)

Decimal value of the first and last Chinese character

Please, could anyone tells me what ares the decimal value of the first and the last Chinese character, the last being the one which has the higher value ? ThanksValp (talk) 10:33, 9 September 2023 (UTC)
