FDC : NEC uPD72065 HDD : HD models have up to an 81MB HDD. HDC : Fujitsu MB89352A (SCSI) SCC : Serial controller - Zilog z85C30 (Dual channel, 1 for RS232, 1 for mouse) PPI : Parallel controller - NEC 8255 (Printer, Joystick) Sound : FM - YM2151, with YM3012 DAC ADPCM - Okidata MSM6258 DMA : Hitachi HD63450, DMA I/O for FDD, HDD, Expansion slots, and ADPCM MFP : Motorola MC68901 - monitor sync, serial port, RTC, soft power, FM synth, IRQs, keyboard RTC : Ricoh RP5C15 ...plus a number of custom chips for video and other stuff... *** Current status (28/12/08) MFP : Largely works, as far as the X68000 goes. PPI : Joystick controls work okay. HDC/HDD : SCSI is not implemented, not a requirement at this point. RTC : Seems to work. (Tested using SX-Window's Timer application) DMA : Works fine. Sound : FM works, ADPCM mostly works (timing(?) issues in a few games). SCC : Works enough to get the mouse running, although only with the IPL v1.0 BIOS Video : Text mode works, but is rather slow, especially scrolling up (uses multple "raster copy" commands). Graphic layers work. BG tiles and sprites work, but many games have the sprites offset by a small amount (some by a lot :)) Still a few minor priority issues around. Other issues: Bus error exceptions are a bit late at times. Currently using a fake bus error for MIDI expansion checks. These are used determine if a piece of expansion hardware is present. Keyboard doesn't work properly (MFP USART). Supervisor area set isn't implemented. Some minor game-specific issues: Salamander: System error when using keys in-game. No error if a joystick is used. Some text is drawn incorrectly. Dragon Buster: Text is black and unreadable. (Text layer actually covers it) Tetris: Black dots over screen (text layer). Parodius Da!: Black squares in areas.
