Coors Light Bowling/Bowl-O-Rama memory map
driver by Zsolt Vasvari
CPU Board:
0000-3fff 3 Graphics ROMS mapped in using 0x4800 (Coors Light Bowling only)
0000-001f Turbo board area (Bowl-O-Rama only) See Below.
4000 Display row selected
4800 Graphics ROM select
5000-57ff Battery backed up RAM (Saves machine state after shut off)
Enter setup menu by holding down the F2 key on the
high score screen
5800-5fff TMS34061 area
First 0x20 bytes of each row provide a 16 color palette for this
row. 2 bytes per color: 0000RRRR GGGGBBBB.
Remaining 0xe0 bytes contain 2 pixels each for a total of
448 pixels, but only 360 seem to be displayed.
(Each row appears vertically because the monitor is rotated)
6000 Sound command
6800 Trackball Reset. Double duties as a watchdog.
7000 Input port 1 Bit 0-3 Trackball Vertical Position
Bit 4 Player 2 Hook Left
Bit 5 Player 2 Hook Right
Bit 6 Upright/Cocktail DIP Switch
Bit 7 Coin 2
7800 Input port 2 Bit 0-3 Trackball Horizontal Positon
Bit 4 Player 1 Hook Left
Bit 5 Player 1 Hook Right
Bit 6 Start
Bit 7 Coin 1
8000-ffff ROM
Sound Board:
0000-07ff RAM
1000-1001 YM2203
Port A D7 Read is ticket sensor
Port B D7 Write is ticket dispenser enable
Port B D6 looks like a diagnostics LED to indicate that
the PCB is operating. It's pulsated by the
sound CPU. It is kind of pointless to emulate it.
2000 Not hooked up according to the schematics
6000 DAC write
7000 Sound command read (0x34 is used to dispense a ticket)
8000-ffff ROM
Turbo Board Layout (Plugs in place of GR0):
Bowl-O-Rama Copyright 1991 P&P Marketing
Marquee says "EXIT Entertainment"
This portion: Mike Appolo with the help of Andrew Pines.
Andrew was one of the game designers for Capcom Bowling,
Coors Light Bowling, Strata Bowling, and Bowl-O-Rama.
This game was an upgrade for Capcom Bowling and included a
"Turbo PCB" that had a GAL address decoder / data mask
Memory Map for turbo board (where GR0 is on Capcom Bowling PCBs:
0000 Read Mask
0001-0003 Unused
0004 Read Data
0005-0007 Unused
0008 GR Address High Byte (GR17-16)
0009-0016 Unused
0017 GR Address Middle Byte (GR15-0 written as a word to 0017-0018)
0018 GR address Low byte
0019-001f Unused
