Re: Major Havoc

Are the quad pokeys on firefox and ROTJ as the one on MH? I have a weird looking
quad pokey. Instead of the board socket being in the middle, this one is off in
the corner. The 4 chips are all in a row.

on the front it says
a041774
atari 83

on the back it says
041775-01
pct f 084

any ideas?
