- Atari Fire Fox hardware
-
- driver by smf, Aaron Giles, Chris Hardy & Scott Waye
-
-short term:
- split driver/vidhrdw/sndhrdw/machine
- add option to centre joystick to enter test menu
-
-it uses a quad pokey package 137323-1221-406???
-the laser disc is a philips lvp 22vp931
-( but maybe this works too... Special Drive: Laser Disc Player - Philips VP-832A )
-
-
-AV# 60626
-Atari "Firefox" V
-
-Laser Disc - 30 minutes - Color - 1983
-
-An interactive CAV laserdisc designed for use in the Atari video arcade game machine.
-Contains over 100 visual and sound segments that include all of the branching possibilities of this game.
-Each segment is two to five seconds long. This disc will play on any player,
-but requires a special level III player for proper control. Video: CAV. Audio: Analog.
