Cool, Thanks all

Much better than those illegible paragraphs in the archives. I guess i will learn both the 8051 and Z80, cant hurt to learn more, eh?

Actually, one reason is my calculator is a Z80 chip and it has an assembler add on feature, and just wondering where the Z80 can and should go.

Thanks again, I will start of with that calculator thing and hopefully will understand the differences later on when i try to make my own Z80 SBC.

Oh, and this is not really a thread close, but a thanks for all the information so far.
