+ 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

+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.
