Disco Monitor Sync Lock
Evan Wessel

PROBLEM
with the sync wire going to the monitor. I'm not
sure why this monitor was overloaded by my
conversion board, but it may be a problem in
future conversions that use this brand monitor.
The sync lock is poor. Everytime the scene
changes, the monitor loses sync.
SOLUTION
I have discovered a cure for the poor sync lock on
my converted Atari I-Robot with a "Disco" brand
monitor (named in the 70's?).
NOTE
My conversion board worked fine on a Wells
Gardner monitor, by the way. Keep this tip in
mind if any of you encounter a problem like this
in the future.
PROCEDURE
I was able to get normal lock by adding a lK
resistor in the sync line. Just splice it in series
