/*************************************************************************** Powertran Cortex 20/04/2012 Skeleton driver. ftp://ftp.whtech.com/Powertran Cortex/ http://www.powertrancortex.com/index.html Uses Texas Instruments parts and similar to other TI computers. It was designed by TI engineers, so it may perhaps be a clone of another TI or the Geneve. Video chip is TMS9928 or TMS9929. 64K RAM. I saw somewhere that the roms are copied into ram at startup. ****************************************************************************/ #include "emu.h" #include "cpu/tms9900/tms9900l.h" class cortex_state : public driver_device { public: cortex_state(const machine_config &mconfig, device_type type, const char *tag) : driver_device(mconfig, type, tag) { } virtual void machine_reset(); virtual void video_start(); UINT32 screen_update_cortex(screen_device &screen, bitmap_ind16 &bitmap, const rectangle &cliprect); }; static ADDRESS_MAP_START( cortex_mem, AS_PROGRAM, 8, cortex_state ) ADDRESS_MAP_UNMAP_HIGH AM_RANGE(0x0000, 0x5fff) AM_ROM AM_RANGE(0x6000, 0xffff) AM_RAM ADDRESS_MAP_END static ADDRESS_MAP_START( cortex_io, AS_IO, 8, cortex_state ) ADDRESS_MAP_UNMAP_HIGH ADDRESS_MAP_END /* Input ports */ static INPUT_PORTS_START( cortex ) INPUT_PORTS_END void cortex_state::machine_reset() { } void cortex_state::video_start() { } UINT32 cortex_state::screen_update_cortex(screen_device &screen, bitmap_ind16 &bitmap, const rectangle &cliprect) { return 0; } static const struct tms9995reset_param cortex_processor_config = { 0, /* disable automatic wait state generation */ 0, /* no IDLE callback */ 0 /* no MP9537 mask */ }; static MACHINE_CONFIG_START( cortex, cortex_state ) /* basic machine hardware */ /* TMS9995 CPU @ 12.0 MHz */ MCFG_CPU_ADD("maincpu", TMS9995L, 12000000) MCFG_CPU_CONFIG(cortex_processor_config) MCFG_CPU_PROGRAM_MAP(cortex_mem) MCFG_CPU_IO_MAP(cortex_io) /* video hardware */ MCFG_SCREEN_ADD("screen", RASTER) MCFG_SCREEN_REFRESH_RATE(50) MCFG_SCREEN_VBLANK_TIME(ATTOSECONDS_IN_USEC(2500)) /* not accurate */ MCFG_SCREEN_SIZE(640, 480) MCFG_SCREEN_VISIBLE_AREA(0, 640-1, 0, 480-1) MCFG_SCREEN_UPDATE_DRIVER(cortex_state, screen_update_cortex) MCFG_PALETTE_LENGTH(2) MCFG_PALETTE_INIT(black_and_white) MACHINE_CONFIG_END /* ROM definition */ ROM_START( cortex ) ROM_REGION( 0x10000, "maincpu", ROMREGION_ERASEFF ) ROM_SYSTEM_BIOS(0, "basic", "Cortex Bios") ROMX_LOAD( "cortex_ic47.bin", 0x0000, 0x2000, CRC(bdb8c7bd) SHA1(340829dcb7a65f2e830fd5aff82a312e3ed7918f), ROM_BIOS(1)) ROMX_LOAD( "cortex_ic46.bin", 0x2000, 0x2000, CRC(4de459ea) SHA1(00a42fe556d4ffe1f85b2ce369f544b07fbd06d9), ROM_BIOS(1)) ROMX_LOAD( "cortex_ic45.bin", 0x4000, 0x2000, CRC(b0c9b6e8) SHA1(4e20c3f0b7546b803da4805cd3b8616f96c3d923), ROM_BIOS(1)) ROM_SYSTEM_BIOS(1, "forth", "FIG-Forth") ROMX_LOAD( "forth_ic47.bin", 0x0000, 0x2000, CRC(999034be) SHA1(0dcc7404c38aa0ae913101eb0aa98da82104b5d4), ROM_BIOS(2)) ROMX_LOAD( "forth_ic46.bin", 0x2000, 0x2000, CRC(8eca54cc) SHA1(0f1680e941ef60bb9bde9a4b843b78f30dff3202), ROM_BIOS(2)) ROM_END /* Driver */ /* YEAR NAME PARENT COMPAT MACHINE INPUT INIT COMPANY FULLNAME FLAGS */ COMP( 1982, cortex, 0, 0, cortex, cortex, driver_device, 0, "Powertran Cybernetics", "Cortex", GAME_NOT_WORKING | GAME_NO_SOUND)
