The Circuit shown below can be used to drive 2 high power stepper motors simultaneously, The 89C51 will generate the appropriate signals for this circuit, while 74LS244 has been used to isolate the micro controller from high voltage portion of the circuit, very soon i will provide the software for this circuit both in assembly and C Language. The signals required for this circuit can also be generated from the PC Parallel port, All the Transistors are 2SD313, and all the Diode are 1N4001,
