GNET Motherboard
Taito, 1998

The Taito GNET System comprises the following main parts....
- Sony ZN-2 Motherboard (Main CPU/GPU/SPU, RAM, BIOS, EEPROM & peripheral interfaces)
- Taito FC PCB (Sound hardware & FLASHROMs for storage of PCMCIA cart contents)
- Taito CD PCB (PCMCIA cart interface)

Also available are...
- Optional Communication Interface PCB
- Optional Save PCB

On power-up, the system checks for a PCMCIA cart. If the cart matches the contents of the flashROMs,
the game boots immediately with no delay. If the cart doesn't match, it re-flashes the flashROMs with _some_
of the information contained in the cart, which takes approximately 2-3 minutes. The game then resets
and boots up.

If no cart is present on power-up, the Taito GNET logo is displayed, then a message 'SYSTEM ERROR'
Since the logo is shown on boot even without a cart, there must be another sub-BIOS for the initial booting,
which I suspect is one of the flashROMs that is acting like a standard ROM and is not flashed at all.
Upon inspecting the GNET top board, it appears flash.u30 is the sub-BIOS and perhaps U27 is something sound related.
The flashROMs at U55, U56 & U29 appear to be the ones that are re-flashed when swapping game carts.

Taito G-Net card info
---------------------

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.
Some of the later games came packaged as a Compact Flash card and a PCMCIA to CF
adapter, however these cards were also locked the same as the older type.
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
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.

       (can be opened if done 'carefully'. But be careful the edges of the top lid are SHARP!)
