Age cutoff, was: Recommendations for operating system

[Evan Koblentz]

>>> At the risk of being overly buzzword compliant, how about something
along the lines of "computing that differs materially from the current
computing paradigm"? That would allow limited discussion of interesting O/S
and other software on currentish computers or "heavily microcoded"
implementations of classic machines, whilst excluding Windows 95 and
modernish hardware discussions.

Or how about just "No beige boxes!"   ;)
