The PCA-6126's floppy disk drive interface supports any combination of two floppy disc drives (5.25 inch, 360 KB and 1.2 MB; and/or 3.5 inch, 720 KB and 1.44MB).
a. Locate the floppy disk drive connector, at J2, on the CPU card.
b. Take the 34-pin daisy-chain cable and make sure that the red or blue strip corresponds with pin 1 of the CPU card's connector (J2).
c. Once you have identified pin 1, connect the cable to the card.
The PCA-6126 also supports the IDE (AT bus), hard disc drive interface, which supports two hard disk drives. The IDE interface connection is located on the CPU card at J1.
a. Take the 40-pin ribbon connector and connect it to the connector at J!, making sure that the red or blue stripe on the connector cable corresponds with pin 1 on J1.
b. Now, connect the other end of the cable to your hard disk drive.
Locate the reset wire on the computer chassis, and connect it to the CPU card's J4 connector.
