Driver by Tomasz Slanina dox@space.pl
***************************************************************************
RAM :
1 x GM76c28-10 (6116) 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
Sound :
AY 3 8910
sound_control :
bit 0 - BC1
bit 1 - BC2
bit 2 - BDIR
bits 3-7 - not connected
