The G-Net system uses a custom PCMCIA card for game software storage. The card is
|
||||
locked with a password and can't be read by conventional means.
|
||||
Some of the cards are made in separate pieces and can be opened. However some
|
||||
are encased in a single-piece steel shell and opening it up destroys the card.

The game uses an analog wheel (5k potentiometer) in the shape of a hand-held
|
||||
control unit and a trigger (another 5k potentiometer) used for acceleration
|
||||
and brake. The trigger and wheel are self centering. If the trigger is pulled back

(like firing a gun) the car goes faster. If the trigger is pushed forward the car

and brake. The trigger and wheel are self centering. If the trigger is pulled back
|
||||
(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.
