A Mac without an OS, when it is capable of working, is only a trip to the seaside short of being a boat-anchor. The idea that a recipient should put up with having no OS for 'legal reasons' is as patently ridiculous as the idea that a motor-vehicle without an engine is a functional acquisition. Whomever you got your G4 from did the reasonable thing by equipping the Mac, if only by leaving an OS rather than installing one, with what it cannot do without and still be a computer.
