(like firing a gun) the car goes faster. If the trigger is pushed forward the car
slows down. The controller looks a lot like the old Scalextric controllers (remember those? :-)
The controller is connected to the ZN2 main board to the 10 pin connector labelled
'ANALOG'. Using two 5k-Ohm potentiometers, power (+5V) and ground are taken from the JAMMA
edge connector or directly from the power supply. The output of the steering pot is
connected to pin 2 and the output of the acceleration pot is connected to pin 3.
The ANALOG connector output pins are tied directly to a chip next to the connector marked
'NEC 78081G503 9810KX189'. This is a NEC 8-bit 78K0-family microcontroller with on-chip 8k ROM,
256 bytes RAM, 33 I/O ports, 8-bit resolution 8-channel A/D converter, 3-channel timer, 1-channel
3-wire serial interface interrupt control (USART) and other peripheral hardware.

Notes:
U* - TOSHIBA TC58V32FT 4M x8 (32MBit) CMOS NAND Flash EEPROM 3.3Volt (TSOP44)
The ROMs use a non-standard format and can not be read by conventional methods.
U7 not populated in Nightraid card, but may be populated in other cards.
U8 not populated in Nightraid card, but may be populated in other cards.
Note: All ROMs have no markings (except part number) and no labels. There are PCB
location marks. The actual cards have been dumped as a single storage device.
