Sega Model 1 Hardware Overview
------------------------------

Note! This document is a Work-In-Progress and covers all the dumped Sega Model 1 games, including....

Star Wars Arcade (C) Sega, 1994
Virtua Fighter   (C) Sega, 1993
Virtua Racing    (C) Sega, 1992
Wing War         (C) Sega, 1994
Tecwar/Netmerc   (C) Sega and Virtuality, 1993

The Sega Model 1 system comprises several PCB's....
CPU PCB   - This is the main PCB. It holds the main CPU, some surface-mounted ROMs and the 3D co-processors
            (manufactured by Fujitsu and known as 'TGP'). There are three different PCB variants, with
            different internal 3D co-processor programs depending on game.
Video PCB - There is only one known revision of this PCB so any game can use this PCB. It contains a very large
            quantity of RAM, some surface-mounted ROMs and some custom Sega video chips. The RGB and Sync is also
            outputted from this PCB. The horizontal sync is 24kHz and requires a medium resolution (24kHz) monitor.
            The video PCB is plugged in below the CPU PCB.
ROM PCB   - This PCB is the same for all games, only the type and number of ROMs differ per game. The ROM PCB is
            plugged in above the CPU PCB.
I/O PCB   - This PCB connects the CPU PCB to the input and output controls via some multi-wire connectors.
Comm PCB  - This PCB is used for communication when linking 2 PCBs together (generally for Virtua Racing only).
            It plugs in below the Video PCB.
Sound PCB - This PCB generates the sound for the game. There is no amplification of the sound here, that is done
            via the Amp PCB.
Motor PCB - This PCB is used to control the motors and steering column clutch used for the force feedback steering.
Amp PCB   - This PCB amplifies the sound generated by the sound PCB.
