"Quick Release" face plate
Dynamic, new design allows the
ticket dispenser to "quickly release"
from it's face plate on your cabinet
or ticket door, no tools needed.
Easily replace one dispenser with
another in just seconds. No tools
necessary! The new face plate
Breakdown by manufacturer, roughly in order of
production, with percentage of points from above:
Wms/Bally (72.0%, avg 9.0%). Sega (12.4%, avg
3.1%). Gottlieb (10.9%, avg 2.7%). Capcom (4.5%,
avg 4.5%).
retrotits any existing Deltronic
Labs machine.
Bottom METAL ticket guide
The extended, durable ticket guide
prevents curled tickets from catching.
Average for manufacturers represents average per-
centage of the points collected by their games. The
total percentages from all manufacturers do not
exactly equal 100% due to roundoff error.
The end results of all this is that games with low
distribution by January, 1996 (WHO dunnit,
Apollo 13, and Waterworld) may have lo~ point
otals not in keeping with general (r.g.p) opinion
of the games. The "Avg" statistic in the rightmost
column of the results is meant to provide a way of
identifying this effect.

Foolproof braking system
Our impressive new braking system
eliminates brake slippage, allowing
foolproof, accurate dispensing.
Optical sensor dust cover
Eliminates dust accumulation and
increases accuracy of the ticket count.

1/0 POWER DRIVER BOARD THEORY OF OPERATION
(PART Two)

I Reset Circuitry U210: I
The 1/0 Power Driver Board will reset in three cases:
1. The CPU Board is in reset The CPU's reset signal is fed into the 1/0 Power Driver Board through
Connector Jl and forces the I/ 0 Power Driver Board into reset.
2. The 5V supply has fallen bellow 4.75V.
3. The watchdog is not being fed by the scanning of the light matrix. More specifically Pin-19 of U6 must
be toggling once every 50ms to prevent the watchdog from resetting.
The scanning of the Light Matrix
is controlled by the CPU through
Connector Jl. LED L204 shows
the reset state of the 1/0 Power
Driver Board.
If this LED is not lit either the
5VDC is below 4.75V or the
CPU Board is holding the 1/0
Power Driver Board in reset.
If the LED is flashing this means
that the watchdog is not being
feed by the CPU Board and the
1/0 Power Driver Board is os-
cillating into and out of reset.
If the LED is continuously on the
board is out of reset and comrnu-
nication from the CPU to the
Lamp Matrix is confirmed.
