TODO:
- VFD display
- Keyboard
- Analog filters and VCA on the back end of the 5503
- SQ-80 support (additional banking, FDC)
SQ-80 is totally broken now, jumping into unmapped memory
] - Analog filters and VCA on the back end of the 5503 (inaccurate)
- duart seems to keep interrupting even after MIDI xmit buffer becomes empty
NOTES:
Commands from KPC are all 2 bytes
