[Micko] 2015-09-27 Added devices & inputs based entirely on guesswork [Robbbert] There seems to be 15 buttons (according to images, I just have board) also there are 8 dips currently set at 00011100 (1 is on) Looks like a LCD display? I think ports 8 & 9 write to it. Also looks like the display should say 8641 when machine is turned on. ToDo: - Need manuals, schematics, etc. - Artwork - Everything ****************************************************************************/ #include "emu.h" #include "cpu/z80/z80.h" #include "machine/z80daisy.h" #include "machine/z80ctc.h" #include "machine/z80pio.h" #include "machine/z80sio.h" #include "sound/beep.h" #include "speaker.h" class brandt8641_state : public driver_device { public: brandt8641_state(const machine_config &mconfig, device_type type, const char *tag) : driver_device(mconfig, type, tag) , m_maincpu(*this, "maincpu") , m_pio1(*this, "pio1") , m_pio2(*this, "pio2") , m_pio3(*this, "pio3") , m_ctc(*this, "ctc") , m_sio(*this, "sio") , m_io_keyboard(*this, "KEY.%u", 0U) , m_beep(*this, "beeper") { } void brandt8641(machine_config &config);
