Z80 – The 1970s Microprocessor Still Alive (2021)

The thread is overwhelmingly a retrocomputing discussion, not an AI/ML debate. Commenters compare transistor counts and clock rates across eras, trade notes on modern Z80 hobby machines, and argue over whether the Z80’s instruction set deserves to be called simple. The one clear AI-related thread treats hands-on Z80 assembly as a welcome antidote to an era dominated by highly abstracted LLM tooling. That view is less a claim that old processors beat AI than a preference for systems where a programmer can see the whole machine, its memory limits, and its instruction behavior. No one evaluates model quality, training methods, safety, benchmarks, or AI products. There is a passing reference to the Z80 inventor’s consciousness-focused ideas, but it attracts no substantive discussion and supplies no usable sentiment about AI. The only relevant mood is mild fatigue with LLM-era abstraction, paired with enthusiasm for programming environments that feel concrete and comprehensible. Since the community does not actually argue over AI, there is no meaningful AI-specific split to extract; most of its energy is nostalgic technical appreciation for old hardware.
