 *   8      off (on = disable the DMA sound hardware)
 *
 * Switch 1 is represented by the lowest bit in the $FF9200 register,
 * and switch 8 is represented by the highest bit. Logic is inverted,
 * i.e. when the switch is "on", the bit is 0.

 * (earliest MegaSTE produced had a DD floppy drive, but later
