/* 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
some complain about Characterizer (protection)
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?)
