/**********************************************************************
Bellfruit Black Box (1979)
Bellfruit's first CPU-based fruit machine platform. The CPU
is a MC6802, with a PIA and extension bus for I/O. Games are
stored on ROM cards up to 8K in size, the CPU board also has a
socket for a 64 nibble NVRAM board. The base system consists
of the CPU board and output board, extension boards provide
more functionality such as reel drive, sound and displays.
The exact set of boards used differs for each game. There were
3 distinct types of reel systems used. Early games had plain
electromechanical reels, which were quickly upgraded to a EM
reel system using opto sensors for positioning, presumably
to prevent cheating. The first games with stepper reels were
introduced in late 1981. Later versions of the CPU board have
an ACIA used for communicating with the LPE DRS 35 datalogger
system, which was introduced in 1982.
TODO:
- Add stepper games
- ACIA datalogger, currently no games use it
- Layouts
- Sound could be more accurate with more circuit information
