  PINBALL
  Spinball (previously Inder)

  Hardware is much the same as Inder, except the digital display is replaced by a DMD controlled by
  a i8031. You need to pick "Pixel Aspect (4:1)" video option in the tab menu.

  There are mistakes in the sound board schematic: IC14 pin12 goes to IC5 pin13 only. IC16 pin 22
  is the CS0 line only. So, they are not joined but are separate tracks. Also, according to PinMAME,
  the outputs of IC11 are all wrong. They should be (from top to bottom): A16, A17, A18, NC, NC,
  CS2, CS1, CS0.

  Also, very unobvious is the fact that PIA ports A and B are swapped around compared to the Inder
  soundcard.

Status
- Bushido: Displays Bushido logo. If you quickly press 5 you get a sound.
- Mach 2: Displays Mach2 logo. Makes a sound if 5 pressed
- Jolly Park: Displays the Spinball logo. After a few moments it plays music
- Verne's World: Display flashes for a second then goes blank. After a few moments music plays.

ToDo:
- Inputs and outputs (currently a copy of inder.c)
- DMD doesn't act on commands
- Electronic volume control on the music card
