Although it shares the name of its predecessor, the "Blue" PowerMac G3 is an altogether different animal. Sporting an all new translucent "easy-open" case design (code named "El-Capitan"), the new G3 was the first Apple model to support FireWire, Apple's new high-speed serial standard. It was also the first professional model to include USB, although it also came with a "legacy" ADB port for backwards compatibility. In a controversial move, Apple chose not to include standard serial ports, a floppy drive, or on-board SCSI (Apple instead chose Ultra ATA). An internal Zip was available, however, as were SCSI expansion cards.
