Re: Fluke and space invaders input ports

just to answer my own post here.. a friend helped me see the error of my ways :) Andy

hi all..

i have a weird board here... withotu going into details, i want to read the input ports, i can't figure out the darn mame source driver to find where the input ports are, but i gather they are on actual ports, not in addresses..

i'm not entirely familiar with the 8080 and how it works, and this is the first time i have had wanted to read the ports... on other cpus (z80 for example,) i just read and interperet an address... hwo do i do this with the 8080 in space invaders??

BTW i'm using a 9100 :)

thanks!

andy
