yes. It supports like 60 different cpu architecture all back to 1979 VAX 790 INCLUDED.

Its also one of few OSes where 32-bit 386 is still tier 1 release.

All from single code source code tree.

Does running NetBSD on VAX from 1979 help to reduce e-waste, though?

[iberator]

Yes if you still run it. 0 metal wasted.
