Needs proper emulation of the 8155 on the sound board. Missing implementation of the low-pass filters on the DAC output. The purpose of the sound PROM is unclear. From the schematics, it seems it should influence the MSM5232 clock. However, even removing it from the board doesn't seem to affect the sound.

The Sound NMI and/or Interrupts aren't likely to be right.
