Floppy Drive Considerations

Nearly any type of soft-sectored, single or double-sided, 40 or 80 track, 5-1/4 inch or 3-1/2 inch floppy disk drive is usable with this interface. Using higher quality drives improves system reliability. Here are some considerations about the selection, configuration, and connection of floppy drives to the Little Board P6d module.

Drive Interface—The drives must be compatible with the board’s floppy disk signal interface, as described below. Ampro recommends any standard PC-or AT-compatible 5-1/4 inch or 3-1/2 inch floppy drive.

Drive Quality—Use high quality, DC servo, direct drive motor floppy disk drives. Drive Select Jumpering—Both drives must be jumpered to the second drive select.

Floppy Cable—For systems with two drives, use a floppy cable with conductors 10-16 twisted between the two drives. This is standard practice for PC-compatible systems.

Head Load Jumpering—When using drives with a Head Load option, jumper the drive for head load with motor on rather than head load with drive select. This is the default for PC-compatible drives.

Drive Mounting—If you mount a floppy drive very close to the Little Board or another source of EMI, you may need to place a thin metal shield between the disk drive and the device to reduce the possibility of electromagnetic interference.

Floppy Interface Configuration

The floppy interface is configured using Setup to set the number and type of floppy drives connected to the system. Refer to the Setup section starting on page 2–48 for details.
