Again I am wanting to design a PCB BOARD. for the above circuit NOT CHANGE CHIPS TO COMPLICATE EVERYTHING worser than already is. notice i am useing lots of repetion so that maybe the point will get across.
What are you so upset about?. I warned you against 8255 based designs and the one you want to use is not, so what is the big deal?. Now, for another warning, the schematic calls for a 8052 BASIC i.e. a preprogrammed device, make sure you know where to get it before you start.
If it upset you that I tell you the above, no need to tell me.
