Hi!

Well, neither of these posts really answers the question. So the cartridge
may be useless, what about the ROM chips?

And yes, the MacOS is pretty well a useless operating system. OS X is only
worse. (No flames thank you, I own and use plenty of Apple equipment
alongside Windows (NT/9x), OS/2, Linux, CE, and DOS...) It's too bad Apple
can't come up with something vastly better and faster.
