The following sections tell how to make each connection. In most
cases you will simply need to connect a standard cable.
Floppy drive connections (CN4)
You can attach up to two floppy disk drives to the SBC-350A's on-
board controller. You can use any combination of 5.25"
(360 KB and 1.2 MB) and/or 3.5" (720 KB, 1.44 MB and 2.88
MB) drives.
The card comes with a 34-pin daisy-chain drive connector cable.
On one end of the cable is a 34-pin flat-cable connector. On the
other end are two sets of floppy disk drive connectors. Each set
consists of a 34-pin flat-cable connector (usually used for 3.5"
drives) and a printed-circuit-board connector (usually used for
5.25" drives). You can use only one connector in each set. The set
on the end (after the twist in the cable) connects to the A: floppy.
The set in the middle connects to the B: floppy.
