Clock 3.579545MHz HM86171 - Hualon Microelectronics HMC HM86171 VGA 256 colour RAMDAC (DIP28) 6264 - UT6264PC-70LL 8k x8 SRAM (DIP28) * - QFP120 IC marked 55102602-12. Logo on the chip is of two 5 1/4 inch floppy discs standing upright and next to each other, with the corner facing up, like 2 pyramids. The middle hole and head access slot are visible too. Chip was manufactured 50th week of 1993 AR17961 - == Oki M6295 (QFP44). Clock = 1.500MHz [12/8]. pin 7 = high VSync - 60Hz HSync - 15.28kHz *********************************************************************************************************************/ #include "emu.h" #include "cpu/z80/z80.h" #include "sound/ay8910.h" #include "sound/okim6295.h" #include "sound/2413intf.h" #define DUNHUANG_DEBUG 0 class dunhuang_state : public driver_device { public: dunhuang_state(const machine_config &mconfig, device_type type, const char *tag) : driver_device(mconfig, type, tag) { } /* video-related */ tilemap_t *m_tmap;
