I Think ill first build a testboard
with the pre-drilled holes and start
adding wires by hand. That way i can
easely re-route address wires to see if
something didn't work out like i wanted.

maybe then ill buy the LS573 for
the pcb design.
What software do you pro's use for
designing a pcb?

Im using Eagle 3.5 (windows version)

Space is always against me, so i cannot
add to many air-wires.
everything should fit on 3.5" x 2.5"
pcb. (The print will be larger, but
there also will be more electronics)
