Therefore we only show black and white. Unknown how to produce sound - there's no commands. MON: (Guesswork by trying things) - A0 : display addresses A0 to A7 - 0,FFF : display addresses 0 to FFE (yes it leaves one out) - G,R : displays registers (R B=3 : set B register to 3) - M,N,Q,T : display or set a specific "register"? (Q : display Q ; Q=6 : set Q to 6) - SP : display or set SP (SP=3B00 : set SP) - PC : display or set PC - L : disassembler (L 0,FF : disassemble range 0 to FF) - K : single-step? (address set by G) (K 99 : single-step at 99) Control Keys - A : display gets a little corrupted - G : back to normal - C : break? (only does a newline) - L : clear screen - M : same as pressing Enter TO DO - How to use the sound? - Does it have colour? - Do the AY ports do anything? - What is Ctrl-A for? - Need software - Need manuals & schematics ****************************************************************************/ #include "emu.h" #include "cpu/i8085/i8085.h" #include "imagedev/cassette.h" #include "sound/ay8910.h" #include "video/mc6845.h" #include "emupal.h" #include "screen.h" #include "speaker.h" #define AY8910_TAG "g12" #define HD46505SP_TAG "h45" class lola8a_state : public driver_device { public: lola8a_state(const machine_config &mconfig, device_type type, const char *tag) : driver_device(mconfig, type, tag) , m_maincpu(*this, "maincpu") , m_rom(*this, "maincpu") , m_ram(*this, "mainram") , m_cass(*this, "cassette") , m_palette(*this, "palette") , m_p_videoram(*this, "videoram") , m_io_keyboard(*this, "KEY.%u", 0U) { } void lola8a(machine_config &config);
