DS89C450 Interfacing

HI..... Currently I am making a CNC Routing Machine and I was planning to use a DS89C450 Microcontroller and UC3770 as my stepper motor driver.... But unfortunately I was not able to make programming(Currently I don't know programming IC's and Microcontoller)..... How could I possibly Interface this two IC's forming a 3 axis machine engraver..... What are needed.....

Interfacing a stepper motor with 8051 core is not difficult . But i don't get what machine you are planning to build and what are your requirement.please specify them!

I'm working on an interrupt-driven monitor for the DS89C450. This makes it possible to run a task and monitor/ change variables etc..
I recomend ad 22.1184 crystal in combination with the in the mcu build in clock-doubler. 44 MIPS makes it a superfast MCU.
For the steppermotors you need for at least 3 x 4 = 12 pins, the 89c450 has only 10 direct i/o-pins, I prefer memorymapped i/o, this makes programming very easy, because all the port can be accessed like normal memmory location. I'm very interested in a 3 axis engraver to use it for the prototyping prints and experiments

Thanks bytebuster... I finally manage to make the 3-axis controls using uc3770 motor driver by editing the codes from arduino exported to mcu ....22.1184 crystal is much better and faster.
but now the problem is how am I gonna make it more like a cnc.. I've read some references about cnc and it has some kind of "home" and "end" for each axis any idea about this?
any idea how to make it simplier.. like using limit switch because the one i read was using IR... also another 1 making me troubled... any reference about this? and addition do you have any reference
about how to make the driver software for computer... i've heared something like OOC...
