The ROM = read only memory = stuff hardcoded into a memory chip which allows the Mac to start up. These ROMs are the reason that only Apple manufactures Macs. I dunno the specifics about the differences between old world and new world ROMs. > 4MB rom based macs ? This is another type of rom. > B&W G3 300 Blue and White G3, 300MHz. Blue and White is used to distinguish these from the Beige G3s. The distinction is based on the color of the case, but there are some differences in the guts. > AGP G4 AGP is a way for driving a display (I think). An AGP G4 is a kind of G4, tho' I cannot remember the other G4s. For instance, I have an AGP G4 at home which was bought in March, 2000. Apple has ways of referring to their machines which typically are rather obscure. At one point in the past this was not the case - every new machine had a new number or name (like quadra 650 or quadra 610 or SE/II or IIci etc.). This was Bad Thing when dealing with the govt. or other folks who like bids on contracts, because bids often need to specify a model number, so if the model numbers change all the time, then the contract is hard to fulfil. If the model numbers stay the same (Powerbook) then things are easier, except there are then strange submodels (Lombard, Bronze, Wallstreet etc.) Bill | The next meeting of the Louisville Computer Society will | be September 23.
