* ToDo:
- slows down while making sound
- MZ800:
- Port CF not done.
- Dips not connected.
- MZ800-mode display not working /Hi-res not coded.
- The CRTC is a very complex custom device, mostly unemulated.
- MZ1500:
- Various ports not done.
- Floppy disk and quick disk not done.
- F4 display is blank.
- Need manuals.
Note: MZ800 hardware starts in memory map (mode A), but switches to MZ700
compatibility mode (mode B) as soon as it starts up. We start in Mode B
because it helps MZ1500 get started and it doesn't break anything.
