/***************************************************************************
Route 16/Stratovox memory map (preliminary)
Notes: Route 16 and Stratovox use identical hardware with the following
exceptions: Stratovox has a DAC for voice.
Route 16 has the added ability to turn off each bitplane indiviaually.
This looks like an afterthought, as one of the same bits that control
the palette selection is doubly utilized as the bitmap enable bit.
