Redemption meters. I have a
couple of questions about the at-
tachment of a meter to a DL-1275
ticket dispenser (see S*TJMarch
'94, V16/Nl).
I have attached a 12V meter to a
Deltronic's DL-1275 board with-
out replacing the 2N2222 and
have had no problems.
Our
My first question is, what hap-
pens when (not if) the dispenser
runs out of tickets? The dispenser
would see a continuous "notch"
and your TIP 120 would be on all
the time providing a continuous
12V to a SV meter.
RUN
HI VOLTS
Secondly, what if the game sup-
plies TTL level SV on the notch
line. (The game supplies the high
signal and the dispenser pulls it
low when it sees a notch.) A
meter attached to 12V will pull
this 5Vup to 12V possibly dam-
aging the game board.
XSISTORS
It certainly doesn't hurt to replace
the 2N2222 with a TIP120 tran-
sistor. But If you would look at a
schematic for Deltronic's DL-4,
you would see that they use a
2N2222 fqr a ticket meter output.
And it drives a 12V meter.

I used a couple of diodes to iso-
late the meter pull-up voltage
from the game board pull-up
voltage and visa versa.
PROCEDURE
• First, cut the notch output
wire.
• On the side going to the
. ticket dispenser board, at-
tach the cathodes of two di-
odes (1N4001, 1N4002, etc.).
• Connect the anode of one
of the diodes to the notch
wire going to the game.
• Connect the anode of the
other diode to one lead of a
12Vmeter.
• The other lead goes to 12V
( or if you want use a SV
meter, connect the other
lead toSV).
• Finally put a third diode
across the meter for fly-back
protection ( cathode to 12V
or SV).

Remember to turn off the
game before attempting
to clear the Ram.

NAMCO HALTS PROJECT
SEGA, MICROSOFf TO DEVELOP 32-BIT PLATFORM
Sega announced early this year a tie-up with
Microsoft, the leading computer software manu-
facturer, for the development of Sega's next gen-
eration 32-bit game machine.
Under terms of the agreement, Microsoft will pro-
vide and develop a new operating system for
Sega's new Saturn hardware. In return, Sega will
adapt their consumer game software for the
Microsoft Windows format so it can be used with
the PC. The Saturn comes with a 32-bit MPU and
64-bit microcomputer.

Competition in the hardware market has grown
increasingly complicated and intense over the past
year, with the entry of a number of companies not
traditionally a part of the game industry, includ-
ing Sony, Matsushita and Sanyo. Nintendo, Sega
and bit market player NEC (the DUO platform)
stand as the major players with Atari, SNK and
newcomer 3DO hoping to gain a share of the
market.

Given the importance of software, Namco has de-
cided to concentrate on developing good software.
The focus of their efforts will be on exploiting the
cababilities of advanced computer graphics tech-
nology employed on their commercial equipment.

Namco also plans to develop interactive movie
software by using the assets of Nikkatsu, a softcore
pornography and action film production company
that Namco acquired when it went bankrupt last
summer.
