Unlike a + real CGA, it is not built around a real MC6845 controller, and so attempts + to get custom video modes out of it may not work as expected. Its 640x200 + CGA mode can be set up to be a 16-color mode rather than mono. + + If you program it with BIOS calls, the PC1512 behaves just like a real CGA, + except: + + - The 'greyscale' text modes (0 and 2) behave just like the 'color' + ones (1 and 3). On a color monitor both are in color; on a mono + monitor both are in greyscale. + - Mode 5 (the 'greyscale' graphics mode) displays in color, using + an alternative color palette: Cyan, Red and White. + - The undocumented 160x100x16 "graphics" mode works correctly. + + (source John Elliott http://www.seasip.info/AmstradXT/pc1512disp.html) + + + Cursor signal handling: + + The alpha dots signal is set when a character pixel should be set. This signal is + also set when the cursor should be displayed. The following formula for alpha + dots is derived from the schematics: + ALPHA DOTS = ( ( CURSOR DLY ) AND ( CURSOR BLINK ) ) OR ( ( ( NOT AT7 ) OR CURSOR DLY OR -BLINK OR NOT ENABLE BLINK ) AND ( CHG DOTS ) ) + + -CURSOR BLINK = VSYNC DLY (LS393) (changes every 8 vsyncs) + -BLINK = -CURSOR BLINK (LS393) (changes every 16 vsyncs) + -CURSOR DLY = -CURSOR signal from mc6845 and LS174 + CHG DOTS = character pixel (from character rom) + + For non-blinking modes this formula reduces to: + ALPHA DOTS = ( ( CURSOR DLY ) AND ( CURSOR BLINK ) ) OR ( CHG DOTS ) + + This means the cursor switches on/off state every 8 vsyncs. + + + For blinking modes this formula reduces to: + ALPHA DOTS = ( ( CURSOR DLY ) AND ( CURSOR BLINK ) ) OR ( ( ( NOT AT7 ) OR CURSOR DLY OR -BLINK ) AND ( CHG DOTS ) ) + + So, at the cursor location the attribute blinking is ignored and only regular + cursor blinking takes place (state switches every 8 vsyncs). On non-cursor + locations with the highest attribute bits set the character will switch + on/off every 16 vsyncs. In all other cases the character is displayed as + usual. + + +TODO: +- Update more drivers in MESS and MAME and unify with src/emu/video/pc_cga.c +- Separate out more cards/implementations +
