/* Notes 17/07/11 DH
 added most other MPU3 sets

 most fail to boot, giving the CPU a 'WAIT' instruction then sitting there
 some complain about Characterizer (protection) and then do the same
 a few boot to show light displays with no LED text
 some display misaligned LED text
 many run VERY slowly, even when the CPU is inactive (inefficient MAME timer system overhead?)

/***********************************************************************************************************
  Barcrest MPU3 highly preliminary driver
  based on MPU4 driver (see mpu4.cpp for credits)

  Thanks to Chris Wren and MFME for documentation, particularly of meters and characteriser.

--- Board Setup ---

This original board uses a ~1.Mhz 6808 CPU, and a number of PIA6821 chips for multiplexing inputs and the like.

A 6840PTM is used for internal timing
A GAME CARD (cartridge) plugs into the board containing the game, and a protection PAL (the 'characteriser').

NOTES:
A number of different modifications exist to the main board, essentially all are compatible with one another aside from RAM sizes.

MOD0- 3 - early boards with small RAM allocations
MOD4- Some modifications on the PCB that didnt work, so field engineers reverted them to MOD3.
MOD5- board revision with bigger RAM and reset sensitivity circuit added on the PCB.

MOD6- adaptation of the PCB to use small daughter card with 6116 RAM

Collectors have gone further with zero power RAM and the like, but these are the ones out in the wild.

TODO: - Distinguish door switches using manual
      - Add discrete sound functionality (same as MPU4 alarm)
      - Is pulse timer ic11 right?
      - 12V meter alarm on hyper viper - how are meters sensed?
