Simulation for Computer Science - inside the CPU. ** Either download or run in Turbo - otherwise it is too 'laggy' ** The keyboard input is converted to binary ASCII and stored in a memory cell. The binary code is read from memory and displayed on the screen. The memory and screen are both limited to 16 bytes. They will wrap-round if further input is received. It may be possible to type too quickly, in which case certain keys will become inoperative, (pretend it is like the old mechanical typewriters when the keys got stuck) ;-) If this happens you will have to stop, then restart the simulation. Enjoy! P.S. I AM aware that starting with 'empty' memory is unrealistic. YOU sort it out!!
