MVS/AES

  • Graphic multiplexer not shown
  • Graphic, audio and sound buses for data are separated. 68k can't access data.
  • Only difference with AES is I/O for cab stuff, dipswitches, gfx multiplexer onboard and backup RAM.

CD

  • Not sure about GPU organisation, Z80 RAM may be connected directly to Z80 -furrtek
  • LC89515/CD data transfers might be on the 68k bus
  • 68k can upload to DRAM with or without DMA.
