Atari Night Driver Driver :)
Memory Map:
0000-01FF R/W SCRAM (Scratchpad RAM)
0200-03FF W PFW (Playfield Write)
0400-05FF W HVC (Horiz/Vert/Char for Roadway)
0600-07FF R IN0
0800-09FF R IN1
0A00-0BFF W OUT0
0C00-0DFF W OUT1
0E00-0FFF - OUT2 (Not used)
8000-83FF R PFR (Playfield Read)
8400-87FF Steering Reset
8800-8FFF - Spare (Not used)
9000-97FF R Program ROM1
9800-9FFF R Program ROM2
(F800-FFFF) R Program ROM2 - only needed for the 6502 vectors
If you have any questions about how this driver works, don't hesitate to
ask. - Mike Balfour (mab22@po.cwru.edu)
