/* Taito Wolf System
Driver by Ville Linde
Three board system consisting of a P5TX-LA PC motherboard, a Taito main board and a rom board.
Hardware configuration:
P5TX-LA Motherboard:
-CPU: Intel SL27J Pentium MMX @ 200 MHz
-Onboard sound: Crystal CS4237B ISA Audio
-Onboard VGA: ATI Rage II 3D Graph (removed from motherboard)
Chipsets (430TX PCIset):
-82439TX Northbridge
-82371EB PIIX4 PCI-ISA Southbridge
Taito W Main Board:
-AMD M4-128N/64 CPLD stamped 'E58-01'
-AMD MACH231 CPLD stamped 'E58-02'
-AMD MACH211 CPLD stamped 'E58-03'
-Panasonic MN1020019 (MN10200 based) Sound CPU
-Zoom ZFX-2 DSP (TMS57002 DSP)
-Zoom ZSG-2 Sound PCM chip
-Taito TC0510NIO I/O chip
-1x RAM NEC 42S4260
-1x RAM GM71C4400
-12x RAM Alliance AS4C256K16E0-35 (256k x 16)
-Mitsubishi M66220 256 x 8-bit CMOS memory
-Fujitsu MB87078 6-bit, 4-channel Electronic Volume Controller
-Atmel 93C66 EEPROM (4kb probably for high scores, test mode settings etc)
-ICS5342-3 GENDAC 16-Bit Integrated Clock-LUT-DAC
-3DFX 500-0003-03 F805281.1 FBI
-3DFX 500-0004-02 F804701.1 TMU
-Rom: E58-04 (bootscreen)
-XTALs 50MHz (near 3DFX) and 14.31818MHz (near RAMDAC)
Taito W Rom Board:
-AMD M4-128N/64 CPLD stamped 'E58-05'
-Program, Sound roms
TODO:
- program ROM is read via parallel port (for offset write, encrypted) and game port!?
- Emulation of the entire Taito Wolf main board which plugs into the PC motherboard's only PCI slot.
- PCI comms between both boards have yet to be understood.
