This is a prototyping machine, very complex and expensive. It does all i/o via uarts, that is TTY, paper-tape puncher, CRT terminal. It also has proms which can be dynamically programmed to alter the machine architecture, so internal ports change meaning mid-stream. (e.g. port 80). The code below is just a sample; it does not represent any aspect of the real hardware. ****************************************************************************/ #include "emu.h" #include "cpu/i8085/i8085.h" #include "machine/terminal.h" #define TERMINAL_TAG "terminal" class imds_state : public driver_device { public: imds_state(const machine_config &mconfig, device_type type, const char *tag) : driver_device(mconfig, type, tag), m_maincpu(*this, "maincpu"), m_terminal(*this, TERMINAL_TAG) { } required_device m_maincpu; required_device m_terminal; DECLARE_READ8_MEMBER(term_r); DECLARE_READ8_MEMBER(term_status_r); DECLARE_WRITE8_MEMBER(kbd_put); UINT8 m_term_data; virtual void machine_reset(); }; READ8_MEMBER( imds_state::term_status_r ) { UINT8 ret = m_term_data; m_term_data = 0; return ret; } READ8_MEMBER( imds_state::term_r ) { return (m_term_data) ? 0x21 : 0x20; } static ADDRESS_MAP_START(imds_mem, AS_PROGRAM, 8, imds_state) ADDRESS_MAP_UNMAP_HIGH AM_RANGE(0x0000, 0x1fff) AM_ROM AM_RANGE(0x2000, 0xffff) AM_RAM ADDRESS_MAP_END static ADDRESS_MAP_START(imds_io, AS_IO, 8, imds_state) ADDRESS_MAP_UNMAP_HIGH ADDRESS_MAP_GLOBAL_MASK(0xff) ADDRESS_MAP_END /* Input ports */ static INPUT_PORTS_START( imds ) INPUT_PORTS_END WRITE8_MEMBER( imds_state::kbd_put ) { m_term_data = data; } void imds_state::machine_reset() { m_term_data = 0; } //static const ins8250_interface imds_com_interface = //{ // 1843200, // DEVCB_NULL, // NULL, // NULL, // NULL //}; static MACHINE_CONFIG_START( imds, imds_state ) /* basic machine hardware */ MCFG_CPU_ADD("maincpu", I8080, XTAL_4MHz) // no idea of clock.
