Stingray pinball by Stern 1977 24-Apr-2022 Version: 14 U2 file CRC32# 3084977E U6 file CRC32# 68D18413 Program each file into 2716 EPROMs and jumper/modify the MPU board appropriately. Key features of this update are: 01. Freeplay support. 02. Ability to disable Extra Balls, or set Extra Ball to score Novelty points. 03. Option to advance Saucer potential on entry rather than from 10 point scores. 04. Reset Saucer potential value to 5,000 points at the start of a ball. 05. Option for Drop Target Special to score Novelty points. 06. Option for Outlane/Standup Target Special to award once per Drop Target bank reset. 07. Show *every* closed switch in switch test mode. 08. Include basic playfield attract mode lamp animation. Update is as follows: 01. Freeplay: enabled when maximum credits DIP switch settings are set to absolute maximum which is now '99' credits: See DIP switch settings below. 02. Drop Target switches now score once only when fallen and are remembered as having dropped. Previously, fallen drop targets could potentially score again and/or the bank fails to reset due to playfield vibrations from poorly adjusted drop target switches. 03. When two Drop Targets are knocked down simultaneously, score is now awarded for both Drop Targets - factory only scored for one Drop Target. 04. Service active switches in reverse order - now the outhole is serviced last so pending playfield switches are dealt with first. 05. Centre rollover button advance bonus lamp extinguishes when maximum bonus is reached; the advance bonus chime then stops erroneously activating. 06. Fixed games fitted with LEDs in switched feature lamp locations from intermittently flickering during Display Test mode. 07. The two Standup Target 1,000 lamps are factory wired in series across the spinner 1,000/10X lamps. This series wiring results in these two lamps illuminating dimly. Now we mirror the lamp driver boards spinner lamp output to J1 pin 11 allowing users to fully drive the spinner/10X and standup target lamps in parallel. 08. DIP switch 28 and 29 now provide master feature options for Extra Ball. Any Specials configured for Extra Ball are awarded based on DIP switch 28 and 29. 09. Added extra Drop Target Special options awarding Novelty points based on DIP switches 23 and 24. 10. Outlane Specials set to 'open ended' or 'once per Drop Target bank reset' via DIP switch 30. 11. In switch test mode, cycle through showing *every* closed switch, not just the first closed switch found. 12. Add a basic playfield attract mode lamp animation so playfield does something during game over. 13. Made the reaction time between quickly pressing the self test button a little more responsive. 14. Sped up the score threshold award setting counter in audit mode. 15. When serving an Extra Ball, don't extinguish the Same Player Shoots Again lamp until a score occurs. 16. If Specials is set to award an Extra Ball and Extra Ball has already been achieved, award 25,000 points instead. 17. If Specials/Score threshold awards are set to award an Extra Ball and it's achieved, now switch off the Extra Ball lane lamp if it was lit without Novelties. 18. Show the code version number at the Ball in Play/Match display on power-up. 19. Play an alarm tune when the Slam switch is activated. 20. Play a descending chime tune when tilting the ball in play. 21. Only activate player displays when they're in the game - no more "00" shown in player displays not playing. 22. If Match feature is disabled, reset Ball in Play to '0' at game over instead of leaving the last ball number shown. 23. Fixed from version 13, flippers incorrectly being enabled at the start of attract mode on power-up. Freeplay: Freeplay is enabled when MPU board DIP switches 18 and 19 are on. Maximum Credits in freeplay is '99'. When DIP Switch 17 is then Off, credits are normally subtracted by 1 at the start of new games / addition of new players (Credit Count mode). When DIP Switch 17 is then On , credits are reset to none at the start of a new game (Credit Reset mode). When credits are none, the credit display is blanked out ('00' is never displayed). Players can still be added while credits are none. When credits are '01' or higher, the credits value will be displayed. If on power-up previous credits were none, credits will be set to '09'. The functions of some dip switches were changed to allow the new features to be optioned as listed below: DSW19,DSW18,DSW17 Maximum Credits Off Off Off 05 Off Off On 10 Off On Off 15 Off On On 20 On Off Off 25 On Off On 30 On On Off 99 (enables Freeplay) Subtract 1 credit at start of new game / addition of new players On On On 99 (enables Freeplay) Reset credits to none at start of new game DSW24,DSW23 Drop Target Special Award Off Off Novelty 50,000 points Off On Novelty 100,000 points On Off Extra Ball (feature based on DSW29 and DSW28 setting) On On Credit DSW27,DSW26 Saucer Award Off Off 10 points scores step through Saucer awards (Factory mode) Off On 10 points scores step through Saucer awards, resets to 5,000 at the start of a ball On Off Saucer entry steps through Saucer awards with 5,000 between each award (long route) On On Saucer entry steps through Saucer awards (short route) On --> DSW27 On setting resets Saucer award to 5,000 at the start of a ball DSW29,DSW28 Extra Ball feature Off Off Extra Balls are disabled.
