Twilight Zone Pinball		Software Revision Information

U6:	Version 9.2
	Checksum: 9392
	Date: April 28, 1995

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.

	Number of buy-in balls allowed is now adjustable.  Enter initials
	is not allowed if more than one buy-in was purchased.


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

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.


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

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).


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

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.

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

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.)

	Checksum: E0D4
	Date: April 16, 1993

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.
