+
+Notes:
+ H8/3044 - Subsino re-badged Hitachi H8/3044 HD6433044A22F Microcontroller (QFP100)
+ The H8/3044 is a H8/3002 with 24bit address bus and has 32k MASKROM and 2k RAM, clock input is 16.000MHz [32/2]
+ MD0,MD1 & MD2 are configured to MODE 6 16M-Byte Expanded Mode with the on-chip 32k MASKROM enabled.
+ EPM7032 - Altera EPM7032LC44-15T CPLD (PLCC44)
+ CXK58257 - Sony CXK58257 32k x8 SRAM (SOP28)
+ KM428C256 - Samsung Semiconductor KM428C256 256k x8 Dual Port DRAM (SOJ40)
+ ULKN2003 - Toshiba ULN2003 High Voltage High Current Darlington Transistor Array comprising 7 NPN Darlinton pairs (DIP16)
+ HM86171 - Hualon Microelectronics HMC HM86171 VGA 256 colour RAMDAC (DIP28)
+ 3V_BATT - 3 Volt Coin Battery. This is tied to the CXK58257 SRAM. It appears to be used as an EEPROM, as the game
+ has on-board settings in test mode and there's no DIPs and no EEPROM.
+ S-1 - ?? Probably some kind of audio OP AMP or DAC? (DIP8)
+ TDA1519A - Philips TDA1519A 22W BTL/Dual 11W Audio Power Amplifier IC (SIL9)
+ CN2 - 70 pin connector for connection of ROM board
+ SW1 - Push Button Test Switch
+ HSync - 15.75kHz
+ VSync - 60Hz
+ ROM BOARD - Small Daughterboard containing positions for 8x 16MBit SOP44 MASKROMs. Only positions 1-4 are populated.
+ Custom ICs -
+ U19 - SUBSINO 9623EX008 (QFP208)
+ H8/3044 - SUBSINO SS9689 6433044A22F, rebadged Hitachi H8/3044 MCU (QFP100)
+ U1 - SUBSINO SS9802 9933 (QFP100)
+ U6 - SUBSINO SS9804 0001 (QFP100)
+ ROMs -
+ V106.U16 - MX27C4000 4MBit DIP32 EPROM; Main Program
+ V100.U7 - ST M27C801 8MBit DIP32 EPROM; Audio Samples?
