Graphics ROM board: 86612-B-2
Program ROM board: 86612-C-2
Main CPU: 68000CP10
Sound CPU: Z80A
MCU: Intel C8751H-88
Main CPU: 68000CP10 @ 24MHz / 2 = 12MHz
Sound CPU: Z80A @ 14.31818 / 4 = 3.579545MHz
MCU: Intel C8751H-88 @ 24MHz / 4 = 6MHz
Sound Chip: YM2151 & YM3012
OSC: 24.000 MHz (on the 86612-B-2 PCB)
Custom: CAPCOM DL-010D-103 (on the 86612-B-2 PCB)
Horizontal scan rate: 15.625kHz
Vertical scan rate: 60.093Hz
Clocks and timings verified on 86612-A-2 board, serial no. 39646
by scope measurement at clock pins
Note; Protection MCU is labelled "TS" without a number and without a coloured
stripe. Maybe its code is not region dependant.
Note: Euro rom labels (IE: "TSE") had a blue stripe, while those labeled
as USA (TSU) had an red stripe on the sticker. The intermixing
of TSE and TSU roms in the parent set is correct and verified.
