Floppy Disk Drive Controller
The 686IPK system board is equipped with a shrouded floppy disk
header that supports two standard floppy disk drives. You can install
any 360KB, 720KB, 1.2MB, 1.44MB, or 2.88MB floppy disk drive. To
prevent improper floppy cable installation, the shrouded floppy disk
header has a keying mechanism. The 34-pin connector on the floppy
cable can be placed into the header only if pin 1 of the connector is
aligned with pin 1 of the header.
Connecting the Floppy Disk Cable
1. Install the 34-pin header connector into
the shrouded floppy disk header (J5) on
the system board. The colored edge of
the ribbon should be aligned with pin 1
of connector J5.
