Thanks again Craig. And yes this is a school assignment. I've spent the last two days on google.com and have found HEAPS of information but the more i read the more i confuse myself.

In this case you're saying that the 8051 is a derivative of the 8052 right? So all the tutorials for the 8052 should apply to the 8051 then?

And what do you mean by datasheet?We have not covered this in class? How do i read one of these sheets?! Are those .pdf files on the chips page the datasheets? I had a look at those a few days ago and it just scared and confused me even more! Is there an easy way to interpret these datasheets?

Cheers...
