The system offers digital counters for time of play and credits (configurable via dips), and game statistics. The PCB doesn't seem to have any markings. Main components are: Z8400AB1 main CPU 3x 6116 RAMs 8-dip bank 4-dip bank 8 MHz XTAL (near main CPU) 20 MHz XTAL lots of TTL 4x digital counters lots of wires There's a very small riser PCB marked 1B-2001-241 with a couple of TTL and a slightly bigger one marked 1B-2001-238 with 3 TTL. */ #include "emu.h" #include "cpu/z80/z80.h" #include "machine/nvram.h" #include "emupal.h" #include "screen.h" #include "tilemap.h" namespace { class plsonic4_state : public driver_device { public: plsonic4_state(const machine_config &mconfig, device_type type, const char *tag) : driver_device(mconfig, type, tag), m_maincpu(*this, "maincpu"), m_gfxdecode(*this, "gfxdecode"), m_videoram(*this, "videoram") { } void plsonic4(machine_config &config);
