/* Experimental exelvision driver Raphael Nabet, 2004 Exelvision was a French company that designed and sold two computers: * EXL 100 (1984) * EXELTEL (1986), which is mostly compatible with EXL 100, but has an integrated V23b modem and 5 built-in programs. Two custom variants of the EXELTEL were designed for chemist's shops and car dealers: they were bundled with application-specific business software, bar code reader, etc. These computer were mostly sold in France and in Europe (Spain); there was an Arabic version, too. Exelvision was founded by former TI employees, which is why their designs use TI components and have architectural reminiscences of the primitive TI-99/4 design (both computers are built around a microcontroller, have little CPU RAM and must therefore store program data in VRAM, and feature I/R keyboard and joysticks) Specs: * main CPU is a variant of tms7020 (exl100) or tms7040 (exeltel). AFAIK, the only difference compared to a stock tms7020/7040 is the SWAP R0 instruction is replaced by a custom microcoded LVDP instruction that reads a byte from the VDP VRAM read port; it seems that the first 6 bytes of internal ROM (0xF000-0xF005 on an exeltel) are missing, too. * in addition to the internal 128-byte RAM and 2kb (exl100) or 4kb (exeltel) ROM, there are 2kb of CPU RAM and 64(?)kb (exeltel only?) of CPU ROM. * I/O is controlled by a tms7041 (exl100) or tms7042 (exeltel) or a variant thereof. Communication with the main CPU is done through some custom interface (I think), details are still to be worked out. * video: tms3556 VDP with 32kb of VRAM (expandable to 64kb), attached to the main CPU. * sound: tms5220 speech synthesizer with speech ROM, attached to the I/O CPU * keyboard and joystick: an I/R interface controlled by the I/O CPU enables to use a keyboard and two joysticks * mass storage: tape interface controlled by the I/O CPU STATUS: * EXL 100 cannot be emulated because the ROMs are not dumped * EXELTEL stops early in the boot process and displays a red error screen, presumably because the I/O processor is not emulated TODO: * dump exeltel tms7042 I/O CPU ROM * everything */ #include "emu.h" #include "cpu/tms7000/tms7000.h" #include "video/tms3556.h" #include "sound/tms5220.h" #include "machine/spchrom.h" //#include "imagedev/cartslot.h" //#include "imagedev/cassette.h" class exelv_state : public driver_device { public: exelv_state(const machine_config &mconfig, device_type type, const char *tag) : driver_device(mconfig, type, tag), m_maincpu(*this, "maincpu"), m_tms3556(*this, "tms3556"), m_tms5220c(*this, "tms5220c") { } required_device m_maincpu; required_device m_tms3556; required_device m_tms5220c; virtual void machine_start(); DECLARE_READ8_MEMBER( mailbox_wx319_r ); DECLARE_WRITE8_MEMBER( mailbox_wx318_w ); DECLARE_READ8_MEMBER( tms7020_porta_r ); DECLARE_WRITE8_MEMBER( tms7020_porta_w ); DECLARE_READ8_MEMBER( tms7020_portb_r ); DECLARE_WRITE8_MEMBER( tms7020_portb_w ); DECLARE_READ8_MEMBER( tms7041_porta_r ); DECLARE_WRITE8_MEMBER( tms7041_porta_w ); DECLARE_READ8_MEMBER( tms7041_portb_r ); DECLARE_WRITE8_MEMBER( tms7041_portb_w ); DECLARE_READ8_MEMBER( tms7041_portc_r ); DECLARE_WRITE8_MEMBER( tms7041_portc_w ); DECLARE_READ8_MEMBER( tms7041_portd_r ); DECLARE_WRITE8_MEMBER( tms7041_portd_w ); /* tms7020 i/o ports */ UINT8 m_tms7020_porta; UINT8 m_tms7020_portb; /* tms7041 i/o ports */ UINT8 m_tms7041_porta; UINT8 m_tms7041_portb; UINT8 m_tms7041_portc; UINT8 m_tms7041_portd; /* mailbox data */ UINT8 m_wx318; /* data of 74ls374 labeled wx318 */ UINT8 m_wx319; /* data of 74sl374 labeled wx319 */ DECLARE_PALETTE_INIT(exelv); TIMER_DEVICE_CALLBACK_MEMBER(exelv_hblank_interrupt); }; TIMER_DEVICE_CALLBACK_MEMBER(exelv_state::exelv_hblank_interrupt) { m_tms3556->interrupt(machine()); } #ifdef UNUSED_FUNCTION static DEVICE_IMAGE_LOAD(exelv_cart) { return IMAGE_INIT_PASS; } static DEVICE_IMAGE_UNLOAD( exelv_cart ) { } #endif /* I/O CPU protocol (WIP): I do not have a dump of the I/O CPU ROMs. The I/O CPU CRC command should enable to dump them, but don't take my word for it. * port B bit >01 is asserted on reset and after a byte is sent to the I/O CPU. * port B bit >02 is asserted after a byte is read from the I/O CPU.
