Yeah, nought but stone tablets back in those days. We had to engrave the code onto the bare silicon with a rusty nail as our only tool. Tell that to young folk these days an' they jus' don't believe you. Still, splendid times, eh Steve ;o)

Fan, since your are in college: Perhaps your college's library has books on the 8051? You have already explored the Tutorials and FAQ on this site, of course. Is there anything in particular why you don't feel confident to write the code? With a background in C and assembly you seem 3/4 of the way already :o)
