PicoZ80 Is a Drop-In Replacement for Everyone's Favorite Zilog CPU
hackaday.comThe underlying project page is extremely long:
It refers to other projects by the same author (?) without explaining them, such as "tranZPUter". That's a very long page too.
It also keeps on about the Sharp MZ range. It never explains why that relatively obscure kit. It barely touches on multi-million selling Z80 machines like the ZX Spectrum.
It is very odd, very long, very unreadable, and put together with passing mentions of LLM-bot assisted coding, I think it might be bot slop.
