The SEGA Naomi Game kits are actually ‘JAMMA Dependent’. What this means exactly is they will only
install into existing JAMMA Cabinets. If an operator tries to install these kits into a Non-JAMMA cabinet,
they will rst have to bring the wiring up to JAMMA Standards.
° Step 1 Disconnect the games original DC Power Supply. You may only use the power supply
provided
with your kit. Be sure to set the voltages going to your Game BD to 5.1 and 3.3 volts DC to assure proper
operation ( Measure on Square Connector at Game BD. Yellow = 5vdc / Brown = 3.3vdc / White = Gnd )
° Step 2 You MUST USE THE COIN METER SUPPLIED WITH YOUR KIT to assure proper Coin ac-
ceptance. A minimum 18 Gauge wire should be used from the Coin Meter 1 output line on your JAMMA
Harness. The 5vdc ( Yellow ) wire found in the wiring bag of your kit MUST BE USED for the supply
voltage to the meter.

ALL SEGA NAOMI KITS
