You can enter commands. - If you have a floppy mounted, it will boot from the disk. - - The system could support 1 or 2 5.25 or 3.5 floppy drives, although 3.5 - was the recommended hardware. Format is similar to the PC 720kb, except - it has 5 sectors of 1024 bytes, giving 800kb total. We only support the - 3.5-sized disks. - - TODO: - - Cassette interface (coded but not working) - - Use kbtro device (tried and failed) - - Optional SCSI controller NCR5380 and hard drive (max 40mb) - - Joystick - - Audio: it could be better - - DAC output is used to compare against analog inputs; core doesn't permit - audio outputs to be used for non-speaker purposes. - - Bios 5 crashes MAME after scrolling about half a screen - -****************************************************************************/ - -#include "emu.h" - -#include "bus/centronics/ctronics.h" -#include "bus/rs232/rs232.h" -#include "cpu/m68000/m68000.h" -#include "cpu/mcs51/mcs51.h" -#include "cpu/z80/z80.h" -#include "imagedev/cassette.h" -#include "imagedev/floppy.h" -#include "machine/6522via.h" -#include "machine/timer.h" -#include "machine/wd_fdc.h" -#include "machine/z80scc.h" -#include "sound/dac.h" -#include "sound/volt_reg.h" -#include "video/mc6845.h" - -#include "emupal.h" -#include "screen.h" -#include "speaker.h" - -#include "formats/applix_dsk.h" - - - -class applix_state : public driver_device -{ -public: - applix_state(const machine_config &mconfig, device_type type, const char *tag) - : driver_device(mconfig, type, tag) - , m_base(*this, "base") - , m_maincpu(*this, "maincpu") - , m_crtc(*this, "crtc") - , m_via(*this, "via6522") - , m_centronics(*this, "centronics") - , m_cent_data_out(*this, "cent_data_out") - , m_fdc(*this, "fdc") - , m_floppy0(*this, "fdc:0") - , m_floppy1(*this, "fdc:1") - , m_ldac(*this, "ldac") - , m_rdac(*this, "rdac") - , m_cass(*this, "cassette") - , m_io_dsw(*this, "DSW") - , m_io_fdc(*this, "FDC") - , m_io_k0f(*this, "K0f") - , m_io_k300(*this, "K30_0") - , m_io_k301(*this, "K30_1") - , m_io_k310(*this, "K31_0") - , m_io_k311(*this, "K31_1") - , m_io_k320(*this, "K32_0") - , m_io_k321(*this, "K32_1") - , m_io_k330(*this, "K33_0") - , m_io_k331(*this, "K33_1") - , m_io_k340(*this, "K34_0") - , m_io_k341(*this, "K34_1") - , m_io_k350(*this, "K35_0") - , m_io_k351(*this, "K35_1") - , m_io_k360(*this, "K36_0") - , m_io_k361(*this, "K36_1") - , m_io_k370(*this, "K37_0") - , m_io_k371(*this, "K37_1") - , m_io_k380(*this, "K38_0") - , m_io_k390(*this, "K39_0") - , m_io_k3a0(*this, "K3a_0") - , m_io_k3b0(*this, "K3b_0") - , m_io_k0b(*this, "K0b") - , m_expansion(*this, "expansion") - , m_palette(*this, "palette") - { } - - void applix(machine_config &config);
