/*
Sega 834-12846 PCB (stickered 970729 0259 II)
The main components are:
MC68EC000FN16 CPU
32.000 MHz XTAL
Sega 315_5296 custom (I/O)
Battery
2x LH52B256N SRAM 32k x 8
2x Lattice pLSI 2032 High Density Programmable Logic
Lattice pLSI 1016 High Density Programmable Logic
NEC D71054GB programmable timer / counter
NEC D71055GB parallel interface unit
2x MB3771 power supply monitor
SLA7026M unipolar stepper motor
YM3438
NEC D7759GC
2x 8-dip banks
3-dip bank
Currently unknown which game this is. The M68K ROM contains several puck-related strings,
so it's supposed to be some kind of air hockey game.
epr codes point to 1996-97 timeframe. Possibly Hockey Stadium (1997)?
