IGT Draw 80 Poker Auto-Bet/Deal Mod
Ronnie Belitz
Lark Amusement
Bristol, Tennessee
MODIFICATION
This modification moderi.zes your Draw 80 to
allow the player to Just hold the Bet button
down until the desired amount is reached
instead of repeatedly pushing the bet but-
ton. The cards are also automatically dealt if
the maximum bet of 8 is reached.
PROCEDURE
Modification: Cut the trace from pin 4 of
074. Run a wire from U74 pin 4 to U35 pin
10. Run another wire from U35 pin 9 to U49
pin 6. Run another wire from U35 pin 8 to
~ U23 pin 9 and fmallyrun a wire from U23 pin
'8 to U65 pin 6. This completes the Auto-Bet
portion.
For the Auto-Deal after 8 bet, run a wire from
U56 pin 10 to U72 pin 6.
CIRCUIT CHANGES
What happens is the high output of the Bet
button from U7 4 is logically "anded" at U35
with the output of the vertical clock at U49
and then the signal is inverted at U23 for
proper polarity to simulate the Bet button
being pressed repeatedly. The clock Is slow
enough to allow the player to bet whatever is
desired. If you have any questions about this
mod, call 615/764-8383.

Atari Assault Stereo Speakers Hookup
Jaines Beck
Greater Southern Distributing Co.
Atlanta, Georgia
PROCEDURE
First of all never connect any part of a
speaker system to ground, even through
another speaker. BTL ainps don't take to it
very well! There should always be outputs
marked"+" and"-" for the speakers.
• Each speaker gets its own "+" and .. -".
• Near the audio ainp you will find a set of
Jumpers marked JPl. Make sure the short-
ing block is in the STEREO position, not the
MONO.
• The SP+ and SP- (pins 10 and L on a
JAMMA connector) are the left channel out-
puts.
• Next. to the JAMMA connector. There is a
.10" spaced 48-pin connector. Pin Al is the
right channel "+", and pin B 1 is the right
channel " "
The connector is clearly
marked.
NOTE
standard inputs and outputs for things like
trackballs and stereo audio sections, etc.
Who knows?
PHASING
One last note: Watch the speaker phasing,
i.e. make sure the speakers are wired iden-
tically: "+" going to "+" on the speakers,
connectors, PCBs and so on. This will give
you the maximum bass response.

Although I don't recommend this, if you're
careful you could solder wires directly to the

board removal later.

I guess they never took stereo gaines into
account when they decided on the JAMMA
standard. Maybe we could push for a new
