Bally Goldball had a very dull attract mode in the original version.
After the Field kit upgrade nothing better happened.
It only made getting the Golden Ball a skill rather than a random feature.
Together with Oliver Okaegi I worked on a new attract mode lights sequence.
While were at it I decided to change some sounds too.
Some were not used, others seem inappropriate.
There some other chages too.

Here is a copy of the readme.txt file:

add 7-digit displays for player 1 - 4 (optional), add version nummber, recalculate checksum.
installation notes (optional):
Replace the four player 6-digit displays with 7-digit displays.
Add an additional wire fom A4 (mpu) J1 Pin 7 to every player display pin 12 (don't connect the credit display !)
installation note:
Burn the U6 amd U2 files on 2732 eproms.
After power on you will see the version number in the one player display.
You can leave the 6 digit displays in place no dip switch is needed, because goldball internally works with 7 digit scoring.
New with version 10:
Improved attract modus (based on ideas from inkochnito).
Enable freegame when dip 25 and dip 26 = on (credit not lower then 01).
This version is based on the Bally Gold Ball service kit, this means when
if dip14 = 0 and dip15 = 0 and dip16 = 0
the "Goldball" is reached when you complete the Goldball letters.
Also dip24 = 1 means:
Top Rollover Button, Goldball special when flashing, comes on at the start of "Goldball" play, and every subsequent ball-in-play if not collected.
Also dip24 = 0 means:
Top Rollover Button, Goldball special when flashing, comes on at the sort of "Goldball" play.
For the following events the sound had changed:
special award, 10 point rebound, Goldball complete, 30 points rebound, PLAY lanes miss letter center (left and right target), spot goldball letter, left return lane, top right star, right star, extra ball awarded, tilt, PLAY already lit, right and inner left outlane, target 1, 2, 3 already lit, target 1, 2, 3, 1-2-3 complete.
Play lanes (50k, extra ball, special) always reset if dip switch 7 is off.
New version 12:
Correct GI problem, Golball complete only played once.

I don't know if it is a bug or not, but there is something with F-14 Tomcat.

When you set the game to award no extra balls, the Flight Insurance (ball saver) still gets activated.
You get the sound, but not the ball.
Just like the extra ball you don't get when awarded.
It would be nice to get Flight Insurance as ball saver, but not the extra ball (tournament setting).
I think the game sees both the Extra Ball and the Flight Insurance as Extra Ball and doesn't award them both.

I hope this makes sence to you....

Get those DARN Duracell batteries off your board!!!!!
They are the worst in batteries.
If it rots like hell, it's Duracell....

I would have thought Altek may have learned from the past Bally boards (or Williams).

This also happens in Pinmame.
Maybe a small oversight from Oliver....
Did you try contacting him?
