z386: An Open-Source 80386 Built Around Original Microcode | Hacker News

Hacker News highlighted z386, an open-source recreation of Intel’s 80386 built from original microcode.

The project drew interest from retrocomputing fans and people preserving legacy x86 architecture.

Discussion then turned to whether real 386 machines still run low-frequency industrial or controller workloads.

The topic underscores how older hardware can remain relevant in specialized production environments.
