1. Introduction
Speaker Connector The host processor board speaker interface is connected via RPIO connector J5 to internal
speaker connector J6, allowing connection of a PC speaker.
Floppy Drive Interface and Power Connector The host processor board floppy drive controller is connected via RPIO connector J5 to
internal 34-pin floppy drive cable connector J10. The ZT 4807 also provides a 4-pin power
connector (J9) that provides +5V, GND, and +12V when input power connector J8 is
connected to an appropriate power source.
Caution: If power is supplied to J8 from the host processor board and the device connected
to J9 draws more power than the host processor board can provide, a power fault or other
problems may occur.
