HAS ANY ONE USED MOTORS RATED OVER 1 AMP WITH THE HANDY BOARD?

Yes.

IF SO, HOW DID YOU GO ABOUT INTERFACING WITH THE HB?

Built my own H-bridge.

DID ANYONE USE THE L293 D/B, OR THE SNJ74 ?

No, they would burn up.

IS IT A BAD IDEA TO PIGGY-BACK MORE THAN TWO OF THESE CHIPS IN PARALLEL,
SAY 3 OR 4?

Yes, it would burn them up. It is much easier to build and H-bridge.

THIS IS MY PROBLEM
MY MOTORS RATE 1AMP CONTINUOUS AND 3.5 PEAK
I'M USING A NICD BATTERY 9.6 VOLTS 950 mAh

A simple common collector H-bridge made out of TIP120 and TIP125 power
transistors will handle this easily.

HOW DO I GO ABOUT DOING THIS????

Build the H-bridge and then hook it up.
