defining 'vintage'

Hmm, have people on here ever found a *sensible* way of defining our interests such that it's obvious we're *not* interested in that x86 clone PC running Windows that you bought in 2002 and have just unearthed in your garage? I've been trying to put the word about a bit locally that I'm interested in rescuing vintage machines, but boy is it ever a struggle - sifting through offers of "very big, old computers" that turn out to just be PCs running a decade-old version of MS Windows is getting a little tiring (that's when the "very big, old computer" doesn't turn out to be just a CRT monitor, of course, which happened to me twice last week) Maybe someone's cracked this particular nut and got the wording down just right - or maybe everyone just lives with it. Setting a cut-off date of 1990 (say) wouldn't work, I think, because a) it might cut out a few interesting non-PC/non-Apple items, and b) a lot of people out there really seem to have no idea how *new* the item that they have is. Idle thoughts for an afternoon, anyway... cheers Jules
