PROBLEM
PROBLEM
It's a tough job removing gum from metal and
plastic surfaces. Games attract this kind of
treatment and we have to deal with it.
Game burns up the AC relay and/ or leaves coils
and flash lamps "On".
SOLUTION
Wildcat Tape Remover TR-60 works great to re-
move bubble gum from glass, metal and plastic.
Three procedures are recommended to prevent
failure of the AC select relay (solenoid 12) located
on the Au,x Driver Board.
It makes good sense, but I had not thought of it
until I had to clean gum out of a Rowe DBA I just
scraped the excess off, put a little TR-60 Tape
Remover on a paper towel and rubbed it right offl
When doing number 1), change the ROM's and
replace the AC relay at the same time.

New Cross-
Reference Utility
NOTE
l) ROM UPDATE
A software problem may cause the
AC select relay (Sol. 12) to fail.
Replace the ROM's currently in
positions ·u26 and 027 with
ROM's labeled I.A5.
2) KNOCKER COIL BRACKET SHORTED TO
GROUND

SUBJECT
New Motorola cross-reference program available
on SflJ's bulletin board system (bbs).
The Knocker coil bracket, located
in the upper left corner of the
backbox, should not come in con-
tact with ground. Be sure that the
ground braid does not touch this
bracket.
3) DtVERTER Coll SHORTED TO GROUND
ITEM
Hot off the magnetic presses! The very latest
Motorola electronic cross-reference utility is
available in the IBM file area. More parts and the
data file is smaller! Faster than the old one too.
NOTE
For more information on SflJ's bulletin board
system see page 20.
Check to make sure that the
ground braid that goes between
the backbox and the lower cabinet
has a clear plastic insulator sleeve
and is positioned so that the braid
won't touch the diverter coil (the
diverter coil is located on the very
back of the playfteld).
