Welcome to the forums.

It's good to start a new thread for your question, especially as you placed it in a three year old thread - http://forum.allaboutcircuits.com/showthread.php?t=5099

I suspect the ADC804 may be commanded to convert and then send data to the 8051. It's probably not too hard.

the ADC 0804 may or maynot be your best choice. There are many I2C devices that will make both hard and software easier to implement.

Will the data be requested from the PC, or will the embedded continously transmit it's data?

Expdient aquisition of an operating system can best be had by purchasing a complete unit, of which many exsist.
