Zilog Z80#Bugs we list a bug that I couldn't find mentioned anywhere else. From the description, it would be a bug, as the User's Manual says that the condition bit C is not affected by OTDR
. However, I think that this wouldn't be such a difficult bug for users to run into, and this makes me think that it should be more widely reported around the Internet. Lastly, there's also a slim chance that it may have been a bug in a few chips, not all Z80s.
Pinging Dhrm77 who introduced this section in [1], who claims to have "(...) found the problem described back in 1991 while making extensive use of the OTIR and OTDR instructions (...)": do you remember where you found it described? Did you try and manage to reproduce it? BernardoSulzbach ( talk) 18:22, 6 July 2021 (UTC)

U880 and the Romanian

is not a Z-80 compatible device. This device has all instructions Z-80 have, but instruction binary bit-assigns are completely different, and does not have binary compatibility. 2400:4051:4CE0:C400:922B:34FF:FED6:A16D ( talk) 11:09, 15 August 2021 (UTC)

Quite a few other entries in Category:Zilog microprocessors could use similar consideration. Piotr Konieczny aka Prokonsul Piotrus| reply here 00:44, 11 August 2023 (UTC)
Zilog announced in April 2024 that it will discontinue production of the Z80 CPU after 48 years on the market. The Z80's architecture is unable to compete with 8-bit RISC and low-cost 32-bit embedded processors. The discontinued versions include NMOS with clock speeds from 4 MHz to 8 MHz and CMOS from 8 MHz to 20 MHz 103.21.175.23 ( talk) 04:50, 9 May 2024 (UTC)
