To look at similar things, what about cars: wasn't the
VW Käfer already a classic, _years_ befor the production
in Germany ended (and in fact, he is still in production
in Mexico!).

So, when is a classic car classic ? Basicly there is a
20 year rule (at least over here), that applies on the
date of first usage of this particular unit.

So, lets apply this: My KIM-1 does up to 500 kop/s (or more
realistic a sustained rate of 200 to 300 kop/s). An actual
multi purpouse SBC system might have an SAB 80535 at 12 MHz
that could do up to 3,000 kop/s (or average 1,200 kop/s) -
so my KIM is still 1/6th of an actual comperable system and
not 1/50th ...

Gee - and I always belived it was a classic system, but with
this rule it is definitly not, since you said when _below_
2% it _can_ be a classic.

Or do you think in matters of useable performance ? My Win95
box (K6-366 running at 417) scrolls the text in about the
same speed than my old A2 ...

I guess both definitions are to tight.
