Re: A86: 102 t-state findpixel routine
what happens when c is something like $73?
$73 and $d7 = $53
you'd have to start the table someplace like $d7d0 or $d7f8 where all the
bits set in the first digit are also set in the third
your other one seems to be even worse because you'd have to have multiple
copies of the table
