J7 is a 2x17 pin header. It mates with Diamond Systems’ cable no. 698008 or any standard floppy drive interface cable. Up to two floppy drives can be connected. The connector furthest away from the others is used to connect to the board. The connector at the far end of the cable (after the twist) is for Drive A, and the middle connector is for Drive B.

J8 is a 2x22 (44-pin) 2mm-pitch pin header. It mates with Diamond Systems’ cable no. 698004, and may be used to connect up to 2 IDE drives (hard disks, CD-ROMs, or flashdisk modules). The 44-pin connector includes power and mates directly with notebook drives and flashdisk modules. To use a standard format hard disk or CD-ROM drive with a 40-pin connector, an adapter PCB such as Diamond Systems’ ACC-IDEEXT is required.
