Ray, look at the schematic page that has the Line Counter on it. This page
also has the signals 'bright' and 'drawing'. You'll see that there is an
RC circuit and a transistor near the middle of the schematic, these are
used to prevent the beam from turning on immediately when a line starts.
Perhaps the problem lies there. Other possibilities are that the line
counter is somehow messed up as this controls when the beam shuts off at
the other end (it never makes it as far as the D/As would have you think).
Or the RC stuff in the monitor cound be hurting, but that would affect ALL
your games. It's hard to say without more info. Do the lines point the right
direction? are they too long? too short? bent?!?! Running the Star Castle
test pattern on it might be helpfull, that way you could (or I could) tell
which end of the line is broke.
BTW we will probably move the 'puter over to the new house this weekend
and I can get back to that CineMenu thing...
