thanks, Alan, I have thought of using C, but right now and for this project I have already successfully implemented reading the bus, verifying the incomming data, and sending it to the LCD. reading the bus is very time critical and it works perfectly now, so I dont want to change to C now. Also, I think I almost understand addressing the RAM now. have to try it and see if I have further questions Thank you Lembit ----- Original Message ----- From: "Alan B.
