It is disabled but if you enable it (by renaming 'digitx' to 'digit9'), it will display things. Perhaps it connected to discrete LEDs or output lines. ****************************************************************************/ #include "emu.h" #include "cpu/i8085/i8085.h" #include "pmi80.lh" class pmi80_state : public driver_device { public: pmi80_state(const machine_config &mconfig, device_type type, const char *tag) : driver_device(mconfig, type, tag) , m_ledready(0) , m_maincpu(*this, "maincpu") { } DECLARE_READ8_MEMBER(keyboard_r); DECLARE_WRITE8_MEMBER(keyboard_w); DECLARE_WRITE8_MEMBER(leds_w); private: UINT8 m_keyrow; bool m_ledready; virtual void machine_reset() override; required_device m_maincpu; }; READ8_MEMBER( pmi80_state::keyboard_r) { char kbdrow[6]; sprintf(kbdrow,"%X",m_keyrow); return ioport(kbdrow)->read(); } WRITE8_MEMBER( pmi80_state::keyboard_w ) { m_keyrow = data; m_ledready = TRUE; } WRITE8_MEMBER( pmi80_state::leds_w ) { if (m_ledready) { m_ledready = FALSE; output().set_digit_value(m_keyrow^0xff, data^0xff); } } static ADDRESS_MAP_START(pmi80_mem, AS_PROGRAM, 8, pmi80_state) ADDRESS_MAP_UNMAP_HIGH AM_RANGE( 0x0000, 0x03ff ) AM_ROM AM_RANGE( 0x0400, 0x1fff ) AM_RAM ADDRESS_MAP_END static ADDRESS_MAP_START(pmi80_io, AS_IO, 8, pmi80_state) ADDRESS_MAP_UNMAP_HIGH ADDRESS_MAP_GLOBAL_MASK(0xff) AM_RANGE(0xf8, 0xf8) AM_WRITE(leds_w) AM_RANGE(0xfa, 0xfa) AM_READWRITE(keyboard_r,keyboard_w) ADDRESS_MAP_END /* Input ports */ static INPUT_PORTS_START( pmi80 ) PORT_START("F6") PORT_BIT(0x10, IP_ACTIVE_LOW, IPT_UNUSED) // does nothing PORT_BIT(0x20, IP_ACTIVE_LOW, IPT_KEYBOARD) PORT_NAME("??")
