The following sections tell how to make each connection. In most
cases, you will simply need to connect a standard cable. All of the
connector pin assignments are shown in Appendix C.

Floppy Drive Connector (CN1)
You can attach up to two floppy disk drives to the
PCA-6751/6751V's on-board controller. You can use any combina-
tion of 5.25" (360 KB/1.2 MB) and/or 3.5" (720 KB/1.44/2.88 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.
your chassis whenever you are working on it. Do not
make connections while the power is on. Sensitive
electronic components can be damaged by a
sudden rush of power. Only experienced electronics
personnel should open the PC chassis.
before touching the CPU card. Modern electronic
devices are very sensitive to static electric charges.
Use a grounding wrist strap at all times. Place all
electronic components on a static-dissipative
surface or in a static-shielded bag when they are not
in the chassis.
