well, from the looks of it, it would cost me some amount of money. as much as possible i would like to stick to what i got right now which is keil.

also, i only have one pc.

ok, this time, never mind the multiprocessor... just a single processor. what i wanted to simulated in particular is the serial io aspect of 8051.

is it possible for me to input values in the serial port during program execution?
