Mac User Group celebrates its 40th birthday this year: I'll be bringing a few old Macs to a meeting venue: Mac Classic II; Pismo G3 PowerBook; Titanium G4 PowerBook; 15-inch G4 PowerBook & the pride of the fleet, the 12-inch G4 PowerBook. I know the PowerBooks all work, not so sure about the Classic, though. I'll have to check that one.
