Willia111s Black Night 2000 Plexi Fix
Eric Wittenzellner
Kemp Enterprises, Inc.
South Windsor, Connecticut
PROBLEM
Cut Plexi With Ends Bent Upwards
U-tum ball contact with underside of upper
playfield.
SYMPTOM
Action in this game is high, and this causes the
ball to jump up to the underside of the playfield,
in turn hitting the solder connections on the "A"
and the "R" on the spell "WAR" rollovers on the
upper playfield.
SOLUTION
We have cut plexi to guard against this problem.
Mount to lower playfield (See Illustrations).

• Shape a slight bend
(1/ 4" - 1/2") in the en-
trance ends of the plexis
