Three variations of this terminal were introduced in 1986. Falco 5220 primarily emulates the DEC VT220; Falco 542 primarily emulates the LSI ADM 42; and Falco 5550 primarily emulates the Wyse WY-50. All three of these terminals have the same video characteristics, with 9x12 characters rendered in a 10x16 cell, displayed in up to 2 screen windows on 24 or 44 lines (not counting the status line). They also likely share the gate array which is thus labeled on the Falco 5220 PCB: LIA3417 041500-001 FALCO TAE8379Δ The Falco 500 is also supposed to be part of the series, though it was introduced earlier and has definitely different video capabilities. ****************************************************************************/ #include "emu.h" //#include "bus/rs232/rs232.h" #include "cpu/z80/z80.h" #include "machine/nvram.h" #include "machine/z80ctc.h" #include "machine/z80sio.h" #include "screen.h" class falco5220_state : public driver_device { public: falco5220_state(const machine_config &mconfig, device_type type, const char *tag) : driver_device(mconfig, type, tag) , m_maincpu(*this, "maincpu") , m_screen(*this, "screen") , m_rombank(*this, "rombank") { } void falco5220(machine_config &config); protected: virtual void machine_start() override; virtual void machine_reset() override; private: u32 screen_update(screen_device &screen, bitmap_rgb32 &bitmap, const rectangle &cliprect); void rombank_w(u8 data); void mem_map(address_map &map); void io_map(address_map &map); required_device m_maincpu; required_device m_screen; required_memory_bank m_rombank; //required_shared_ptr m_cram; // 1x or 2x NEC D43256C-10L //required_shared_ptr m_aram; // 1x or 2x NEC D43256C-10L }; u32 falco5220_state::screen_update(screen_device &screen, bitmap_rgb32 &bitmap, const rectangle &cliprect) { return 0; } void falco5220_state::rombank_w(u8 data) { m_rombank->set_entry(data & 3); } void falco5220_state::mem_map(address_map &map) { map(0x0000, 0x7fff).rom().region("roms", 0); map(0x8000, 0xbfff).bankr("rombank"); map(0xc000, 0xdfff).ram().share("nvram"); map(0xe000, 0xffff).ram(); } void falco5220_state::io_map(address_map &map) { map.global_mask(0xff); map(0x00, 0x00).w(FUNC(falco5220_state::rombank_w)); map(0x60, 0x63).rw("sio", FUNC(z80sio_device::ba_cd_r), FUNC(z80sio_device::ba_cd_w)); map(0x70, 0x73).rw("ctc", FUNC(z80ctc_device::read), FUNC(z80ctc_device::write)); map(0x88, 0x8b).nopw(); // second SIO? map(0x90, 0x93).nopw(); // second CTC? } void falco5220_state::machine_start() { m_rombank->configure_entries(0, 4, memregion("roms")->base(), 0x4000); } void falco5220_state::machine_reset() { m_rombank->set_entry(0); } static INPUT_PORTS_START(falco5220) INPUT_PORTS_END static const z80_daisy_config daisy_chain[] = { { "ctc" }, { "sio" }, { nullptr } }; void falco5220_state::falco5220(machine_config &config) { Z80(config, m_maincpu, 12.288_MHz_XTAL / 2); // Z0840006PSC m_maincpu->set_addrmap(AS_PROGRAM, &falco5220_state::mem_map); m_maincpu->set_addrmap(AS_IO, &falco5220_state::io_map); m_maincpu->set_daisy_config(daisy_chain); NVRAM(config, "nvram", nvram_device::DEFAULT_ALL_0); // CXK5864AP-10L + battery z80ctc_device &ctc(Z80CTC(config, "ctc", 12.288_MHz_XTAL / 2)); // Z0843006PSC ctc.set_clk<0>(12.288_MHz_XTAL / 10); ctc.set_clk<1>(12.288_MHz_XTAL / 10); ctc.intr_callback().set_inputline(m_maincpu, INPUT_LINE_IRQ0); z80sio_device &sio(Z80SIO(config, "sio", 12.288_MHz_XTAL / 2)); // Z0844006PSC sio.out_int_callback().set_inputline(m_maincpu, INPUT_LINE_IRQ0); screen_device &screen(SCREEN(config, "screen", SCREEN_TYPE_RASTER)); screen.set_raw(37.98_MHz_XTAL, 1500, 0, 1320, 422, 0, 400); // 25.32 kHz/60 Hz confirmed screen.set_screen_update(FUNC(falco5220_state::screen_update)); } ROM_START(falco5220e) ROM_REGION(0x10000, "roms", 0) // (c) 1987 FDP, Inc 2321 ROM_LOAD("152321-000.bin", 0x0000, 0x8000, CRC(45ef4a68) SHA1(71e12dce710f9b66290618e299b2382834845057)) ROM_LOAD("152321-001.bin", 0x8000, 0x8000, CRC(91056626) SHA1(217ca3de76d5e9861284f5b64f8eff8e541fad3d)) ROM_END ROM_START(falco5220s) ROM_REGION(0x10000, "roms", 0) // (c) 1989 FDP, Inc 0412 ROM_LOAD("168412-00.bin", 0x0000, 0x8000, CRC(de34b149) SHA1(6a4824eb5941f4c6475949011e64b28ab185ba59)) ROM_LOAD("168412-01.bin", 0x8000, 0x8000, CRC(e6facd5b) SHA1(2b9bf3ca18e3e30032dcb6faf0809b6cf6f467ac)) ROM_END COMP(1987, falco5220e, 0, 0, falco5220, falco5220, falco5220_state, empty_init, "Falco Data Products", "Falco 5220e", MACHINE_IS_SKELETON) COMP(1989, falco5220s, falco5220e, 0, falco5220, falco5220, falco5220_state, empty_init, "Falco Data Products", "Falco 5220s", MACHINE_IS_SKELETON)
