Connecting Floppy Drives
See the picture below for an example of a floppy cable. Most of the current floppy drives on the
market require that the cable be installed with the colored stripe positioned next to the power
connector. In most cases, there will be a key pin on the cable which will force a proper connection
of the cable.
The first floppy drive (sometimes denoted as A:) is
usually attached to the end of the cable with the twist
in it. Drive B: is usually connected to the second or
third connector in the cable (the second or third
connector after you install Drive A:). Refer to your
floppy drive's installation instructions (if available), or
contact your dealer if you are unsure about how to
attach the floppy drive(s). Remember, you can only
have 2 floppy drives connected at any given time.
