demand for small-batch yarn is facilitating a resurgence of tiny mills which often use salvaged machinery. (the industry largely collapsed in the nineties due to globalization).

i've been contemplating the potential for a parallel in chip manufacturing: if there's sufficient interest in 8 bit to merit the design and local fabrication of something 6502-like, using salvaged semiconductor equipment.

(this would of course rely on being an ideological project since there's no competing financially)
