If we are going to re-adjust the number of years to
include/exclude,
then let's just scrap the entire concept of a fixed number of years,
and declare that classic computers ran until August 10, 1981 (the
day before the IBM PC announcement).
And thus exclude some true classics, like the HP Integral and PERQ 2T4
Much as I hate to exclude a particalar type of machine, maybe we should
just say that a machine is not classic if a substantially similar machine
is still mainstream, and thus has support available elsewhere. That
would, I think, cut out most Pentium-based machines (but would arguably
still include PC/XTs, etc).
