Galaxy Games
----
This is a multi-game coctail cabinet released in 1998. Namco seems to have
made some cartridges for it (or at least licensed their IP).
Trackball-based. 'BIOS' has 7 built-in games. There are two LEDs on the PCB.
More information here : http://www.cesgames.com/museum/galaxy/index.html
----
Board silkscreend 237-0211-00
REV.-D
Cartridge based mother board
Holds up to 4 cartridges
Chips labeled
GALAXY U1 V1.90 12/1/98
GALAXY U2 V1.90 12/1/98
NAMCO 307 Cartridge has surface mount Flash chips in it (not dumped?).
Looks like it requires a medium resolution monitor
Motorola MC68HC000FN12
24 MHz oscillator
Xilinx XC5206
Xilinx XC5202
BT481AKPJ110
NKK N341024SJ-15 x8 (128kb RAM)
OKI M6295 8092352-2
PAL16V8H-15 @ U24 Blue dot on it
PAL16V8H-15 @ U25 Yellow dot on it
PAL16V8H-15 @ U26 Red dot on it
PAL16V8H-15 @ U27 Green dot on it
PAL16V8H-15 @ U45 red dot on it
----
There are a few built-in games on the hardware, so the driver can grow mature without carts dumped.
TODO : This is a skeleton driver. Just about everything.
