/***************************************************************************

Jack Rabbit memory map (preliminary)

driver by Nicola Salmoria
thanks to Andrea Babich for the manual.

TODO:

- implement discrete filters for analog signals 1 to 5 and attenuation control
  for signal 5 (74LS156)

- The 8910 outputs go through some analog circuitry to make them sound more like
  real intruments.
  #0 Ch. A = "rullante"/"cassa" (drum roll/bass drum) (selected by bits 3&4 of port A)
  #0 Ch. B = "basso" (bass)
  #0 Ch. C = straight out through an optional filter
  #1 Ch. A = "piano"
  #1 Ch. B = "tromba" (trumpet) (level selected by bit 0 of port A)
  #1 Ch. C = disabled (there's an open jumper, otherwise would go out through a filter)

- some minor color issues (see video)


Notes:
- There is a protection device which I haven't located on the schematics. It
  sits on bits 4-7 of the data bus, and is read from locations where only bits
  0-3 are connected to regular devices (6400-6407 has 4-bit RAM, while 6c00-6c07
  has a 4-bit input port).

- The 6802 driving the TMS5220 has a push button connected to the NMI line. On
  Zaccaria pinballs, when pressed, this causes the speech 6802 and the slave
  sound 6802 to play a few speech effects and sound effects;
  This currently doesn't work in MAME, and tracing the code it seems the code is
  possibly broken, made up of nonfunctional leftovers of some of the pinball test
  mode code.
