SUBJECT:
Switchcaps
DESCRIPTION:
MODEL:
r X 7 8 M I
If a t power-up two switches a r e activated a t t h e s a m e t i m e (indicated by both the
Joystick and Paddle, or Novice and Expert LED'S "on" at t h e s a m e time), you must
shorten t h e switchcap hand ends with sand paper,
to
eliminate binding.
DATE:
If t h e switchcaps
seem
to b e binding when 'activated on Rev. 4 PCBs, tilt t h e
momentary switches (S2-S9) toward t h e player port side of t h e board so t h a t t h e r e is a
.030 inch gap between t h e board and t h e leading edge of t h e switch bottom (a manual
approximation is usually successful). Some Rev. 4 PCB's
have
a shim glued t o t h e PCB
t o c o r r e c t this problem.
