Operation Wolf uses similar hardware to Rainbow Islands and Rastan.
The screen layout and registers and sprites appear to be identical.
Taito TC0030CMD chip labeled B20-18 (at least for the US boards)
Taito PC060HA likes like it might be a DIP28 Fujitsu MB884x chip
There are 4 socketted PALs (DIP20 type PAL16L8ACN) labeled B20-09
through B20-12 (not read)
OSC: Main board: 16MHz, 12MHz & 26.686MHz
Sound board: 8MHz (Next to Z80 & YM2151)
CPU: TS68000CP8 (Rated for 8MHz)
