I need to control two 40-50 Amp motors (from an old electric wheel chair)
using PWM.  Reading the recent postings on the Miniboard, I notice that 
it's capable of controlling four DC motors up to only 600 mA of current.
Does anyone have an idea for a fix, like maybe driving four hexfets in the
familiar H-pattern?  Any ideas will be appreciated.

Thanx,
Jim Disbrow
