One of the dangers (to bring things around to being
on-topic for this
list) is that people will start running Linux or a BSD exclusively on
their vintage hardware. A lot of the character of the vintage system is
lost when it has the same BASH prompt as any old PC Clone someone bought
at a garage sale.
For much te same reason I am actively against running PNX (PERQ Unix,
basically a V7 derrivative) on classic PERQs.
If you want a unix box, then get a unix box (e.g. a PC running linux or
*BSD). IMHO a PERQ should run POS (the original PERQ operating system,
written mostly in a very extended Pascal). POS is better for running
user-written microcode too...
