Mismatching modes is responsible for the semigraphic modes on the CoCo. Timing: (source Motorola M6847 Manual) Horizontal Sync: Total Period: 227.5 clock cycles @ CLK(0) + DHS_F - falling edge (high to low) @ CLK(16.5) + DHS_R - rising edge (low to high) @ CLK(42) - left border start @ CLK(71.5) - body start @ CLK(199.5) - right border start @ CLK(227.5) + DHS_F - falling edge (high to low) ... Field Sync: Total Period 262*227.5 clock cycles @ CLK(0) + DFS_F - falling edge (high to low) @ CLK(32*227.5) + DFS_R - rising edge (low to high) @ CLK(262*227.5) + DFS_F - falling edge (high to low) (262.5 for the M6847Y) DHS_F: 550ns DHS_R: 740ns DFS_F: 520ns DFS_R: 500ns The M6847T1 is a later variant of the M6847 chip that implements lower case support and some other nifty features. This chip is in the CoCo 2B. I have not been able to find a pinout diagram for this chip so I am assuming that the extra text modes on the CoCo 2B are activated by the GM2-0 pins. This needs to be confirmed. **********************************************************************/ #include "emu.h" #include "video/mc6847.h" //************************************************************************** // CONSTANTS //************************************************************************** #define TOP_BORDER 25 #define USE_HORIZONTAL_CLIP false #define TIMER_HSYNC_PERIOD (227.5) #define TIMER_HSYNC_OFF_TIME (10.0) #define TIMER_HSYNC_ON_TIME (TIMER_HSYNC_OFF_TIME + 16.5) #define TIMER_FSYNC_OFF_TIME (TIMER_HSYNC_PERIOD * TOP_BORDER + TIMER_HSYNC_ON_TIME) #define TIMER_FSYNC_ON_TIME (TIMER_HSYNC_PERIOD * (TOP_BORDER + 192) + TIMER_HSYNC_ON_TIME) #define LOG_SCANLINE 0 #define LOG_HSYNC 0 #define LOG_FSYNC 0 const UINT32 mc6847_base_device::s_palette[mc6847_base_device::PALETTE_LENGTH] = { MAKE_RGB(0x07, 0xff, 0x00), /* GREEN */ MAKE_RGB(0xff, 0xff, 0x00), /* YELLOW */ MAKE_RGB(0x3b, 0x08, 0xff), /* BLUE */ MAKE_RGB(0xcc, 0x00, 0x3b), /* RED */ MAKE_RGB(0xff, 0xff, 0xff), /* BUFF */ MAKE_RGB(0x07, 0xe3, 0x99), /* CYAN */ MAKE_RGB(0xff, 0x1c, 0xff), /* MAGENTA */ MAKE_RGB(0xff, 0x81, 0x00), /* ORANGE */ MAKE_RGB(0x00, 0x00, 0x00), /* BLACK */ MAKE_RGB(0x07, 0xff, 0x00), /* GREEN */ MAKE_RGB(0x00, 0x00, 0x00), /* BLACK */ MAKE_RGB(0xff, 0xff, 0xff), /* BUFF */ MAKE_RGB(0x00, 0x7c, 0x00), /* ALPHANUMERIC DARK GREEN */ MAKE_RGB(0x07, 0xff, 0x00), /* ALPHANUMERIC BRIGHT GREEN */ MAKE_RGB(0x91, 0x00, 0x00), /* ALPHANUMERIC DARK ORANGE */ MAKE_RGB(0xff, 0x81, 0x00) /* ALPHANUMERIC BRIGHT ORANGE */ }; //************************************************************************** // FRIEND DEVICE //************************************************************************** //------------------------------------------------- // ctor //------------------------------------------------- mc6847_friend_device::mc6847_friend_device(const machine_config &mconfig, device_type type, const char *name, const char *tag, device_t *owner, UINT32 clock, const UINT8 *fontdata, bool is_mc6847t1, double tpfs, int field_sync_falling_edge_scanline) : device_t(mconfig, type, name, tag, owner, clock), m_character_map(fontdata, is_mc6847t1) { m_tpfs = tpfs; // The MC6847 and the GIME apply field sync on different scanlines m_field_sync_falling_edge_scanline = field_sync_falling_edge_scanline; } //------------------------------------------------- // setup_timer - sets up a single timer relative // to the clock //------------------------------------------------- ATTR_FORCE_INLINE emu_timer *mc6847_friend_device::setup_timer(device_timer_id id, double offset, double period) { emu_timer *timer = timer_alloc(id); timer->adjust( attotime::from_ticks(offset * 4, m_clock * 4), 0, attotime::from_ticks(period * 4, m_clock * 4)); return timer; } //------------------------------------------------- // device_start - device-specific startup //------------------------------------------------- void mc6847_friend_device::device_start(void) { /* create the timers */ m_frame_timer = setup_timer( TIMER_FRAME, 0, m_tpfs * TIMER_HSYNC_PERIOD); m_hsync_on_timer = setup_timer( TIMER_HSYNC_ON, TIMER_HSYNC_ON_TIME, TIMER_HSYNC_PERIOD); m_hsync_off_timer = setup_timer(TIMER_HSYNC_OFF, TIMER_HSYNC_OFF_TIME, TIMER_HSYNC_PERIOD); m_fsync_timer = timer_alloc(TIMER_FSYNC); m_top_border_scanlines = 0; m_body_scanlines = 0; m_wide = false; set_geometry(25, 192, false); /* save states */ save_item(NAME(m_physical_scanline)); save_item(NAME(m_logical_scanline)); save_item(NAME(m_logical_scanline_zone)); save_item(NAME(m_horizontal_sync)); save_item(NAME(m_field_sync)); /* artifacting */ m_artifacter.setup_config(this); } //------------------------------------------------- // device_start - device-specific reset //------------------------------------------------- void mc6847_friend_device::device_reset(void) { device_t::device_reset(); m_video_changed = true; } //------------------------------------------------- // device_post_load - device-specific post load //------------------------------------------------- void mc6847_friend_device::device_post_load(void) { device_t::device_post_load(); m_video_changed = true; } //------------------------------------------------- // update_field_sync_timer //------------------------------------------------- void mc6847_friend_device::update_field_sync_timer(void) { /* are we expecting field sync?
