Twilight Zone 9.2


Version 9.2 Date: February 28, 1995 U6: Checksum: 9392
Changes from revision L-4:

         Bonus X lamp is now ensured to be off at the end of Lost in the Zone.

         Extended ball recycling time at end of Lost in the Zone.

         Fixed the multiball jackpot display effect.  It would incorrectly
         report the score awarded if the jackpot was over 127 million and
         the jackpot was doubled by the powerball.

         The game can now hold scores up to 1 trillion, even though scores
         will be truncated when they are above 9.9 billion.  (High scores
         in the 10 billions are now displayed.)

         Added a new adjustment to allow ball savers beyond ball one.
         FREE RIDE TIME (A.2 27) must be set to non-zero for this to
         be enabled.

         Despite what the note in P-1 says, the game would not play multiball
         correctly with only one ball installed.  It now does.


       Version L-4
       Date: June 14, 1993
U6:    Checksum: 3204

Changes from revision L-3:

         Added "EX. EASY" settings for piano and slot.
         When set to extra easy, they are always lit, and
         do not need to be requalified.

         Added Italy 3 pricing of 2 coins per play with
         no Bonus.

         Added logic to allow the 1-coin buy-in on the
         new Italy 3 pricing.  Selecting Italy 3 pricing also
         auto-sets the 1/coin for buy-in adjustment.


       Version L-3
       Date: May 24, 1993
U6:    Checksum: 6403

Changes from revision L-2:

         When either ITALY 2 or SWISS 2 pricing is selected, the game
         will automatically switch to the CREDIT OR COIN setting
         for the A.2 01 Buy-in adjustment.

         If the ball popper pops, but a gumball is not dispensed,
         the game will dispense a gumball (1 only) on any ball search
         before the ball ends (if the ball ends, there obviously isn't
         an extra ball in the gumball machine).


       Version L-2
       Date: May 7, 1993
U6:    Checksum: B902

Changes from revision L-1:

         Enhanced logic on the gumball entry opto.  Spurious switch hits
         after a popper pop no longer dispenses an extra ball.

         Fixed the difficulty presets.  They were causing German and Euro
         jumpered games to change the pricing incorrectly.

         Gumball test now kicks balls out of the lockup.

         The logic for loading "extra" balls into the gumball machine has
         been enhanced to check for a stuck 4th trough switch.

         Added an adjustment for the number of balls in the gumball machine.

         Camera award equalized during tournament play.


       Version L-1
       Date: April 23, 1993
U6:    Checksum: E801

Changes from revision P-4:

         Initial release to production.

         Gumball machine no longer empties during Lost in the Zone if it
         is not working.

         Powerball detection can no longer be faked out during multiball.

         Equalized the slot machine door award in tournament.

         If the powerball is detected out during rematch, the game will
         go into powerball mode when rematch expires.

         Enhanced broken switch logic for the left ramp.

         Center magnet names (switch and coil) changed to "NOT USED".

         Pressing both flippers will speed up the bonus countdown.

         Enhanced the broken switch logic on the powerfield enter switch.

         Added Super Robot award at 99 robots.  (Left ramp or lock.)

         Fixed rematch effect.

         Side kicker (rocket) no longer makes sounds in tilt and game over.

         Fixed a bunch of sound/music effect priority clashes.

         Clock now keeps time in attract mode after 2 minutes of idle time.

         Enhanced the autofire logic for Lost in the Zone.


       Version P-4
       Date: April 16, 1993
U6:    Checksum: E0D4

Changes from revision P-3:

         Enhanced gumball test.

         Added magnet test.

         Implemented "Disable Gumball" adjustment.  Gumballs are simulated
         in this case, or when the right magnet opto or gumball diverter
         are broken.

         Game now detects if the powerball is missing.  When it is missing,
         disabled by adjustment, or the gumball machine is not working,
         then the powerball is simulated.

         Clock errors are now detected and reported.

         Added French translations.

         The powerball is now tracked through the gumball machine to count
         the number of balls stored there.  An error is reported if the
         count is incorrect.

         Once it is verified that there is at least one ball in the gumball
         machine, then gumball dispensing is sped up.  (It is started on
         the ball popper.)

         Added buy-in cancel display messages.

         Added broken ramp switch compensation logic.


       Version P-3
       Date: April 2, 1993
U6:    Checksum: 47D3

Changes from revision P-1:

         Added German translations.

         Added new extra ball effects for 2nd and 3rd extra balls.

         Dead End bonus added for 8 and 20 dead ends.

         Clock Millions damage bonus added for 6 hits on the clock.

         Changed buy-in pricing for Italy to 1 coin/1 credit.

         Added GUM-BALL combo award.

         Multiball modes now work properly with only 1 ball installed in
         the game.

         Added Lost in the Zone champ.
