Diskette-Drive Controller
2.3.7 Diskette-Drive Controller
The diskette-drive controller is on the system board. The controller
connects to the diskette drives through a 34-pin cable connector (the
connector on the system board is a 40-pin cable-connector). Signals and
voltages are supplied through the diskette-drive cable that plugs into the
connector. On the Model 90, these signals and voltages can operate a
maximum of three devices (one can be a 5.25-inch device). On the Model
95, these signals and voltages also can operate a maximum of three devices
(one can be a 5.25-inch device).
