Fluke and space invaders input ports

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!
