+RAM :

+ 3 x 2114 - VRAM (only 10 bits are used )

+ROM:
+ 27256 + 27128 for code/data
+ 3x2764 for gfx
+
+PROM:
+ 82S123 32x8
+ Used for system control
+ (d0 - connected to ROM5 /CS , d1 - ROM4 /CS, d2 - RAM /CS , d3 - to some logic(gfx control), and Z80 WAIT )
+
+Memory Map :
+ 0x0000 - 0xbfff - ROM
+ 0xc000 - 0xcfff - RAM
+ 0xd000 - 0xdfff - VRAM mirrored write,
+ tilemap offset = address & 0x3ff
+ tile number = bits 0-7 = data, bits 8,9 = address bits 10,11
+
+Video :
+ No scrolling , no sprites.
+ 32x32 Tilemap stored in VRAM (10 bits/tile (tile numebr 0-1023))
+
+ 3 gfx ROMS
+ ROM1 - R component (ROM ->(parallel in) shift register 74166 (serial out) -> jamma output
+ ROM2 - B component
+ ROM3 - G component
+
+ Default MAME color palette is used

+ bit 0 - BC1
