I am trying to help a friend adjust the settings on a Williams World Cup. They must have had some great drugs in the 70s!

Near as I can figure you press a button, change 2 banks of switches to encoded values and then press another button. Simple as pie right?

I'd like to validate a setting to make sure I have it right: Set Setting 01 "Replay 1" to 100000.

The number entered for function 01 is multiplied by 10k to set the replay value so I should set this data to 10.

Here are my instructions:
Press the "Diagnostic" bottom button

Set the "Data" top bank to "10" from Chart 2
0
0
0
0
1
0
0
0

Set the "Function" bottom bank to 1 from Chart 1
1
0
0
0
0
0
0
0

Press the "Enter" top button
LEDs should blink

Is this correct?

HOT DAMN! I've been updated to friend Ok, so here's where I set everything (see picture).

Powered on game.
Pushed bottom button, "Diagnostic"
Set FUNCTION dip switches to #8 on, all other off (chart 1 indicates this for function 01, Replay 1)
Set DATA dips as per Chart 2, 10 (4 on, all other off)
Push DATA button...

LED's on MPU flash indicating the data was saved....but, it's still not set on a FREE game at 100,000 points.

Setting 6 sets the replay award. It can be:
08 Match On-Credit
09 Match On-Extra Ball
12 Match Off-Credit
13 Match Off-Extra Ball

"Match On"....isn't that referring to the Match feature at the end of a game? MATCHING the last 2 numbers of your score to some random number generated?

I am not sure but I think 08 sets the match on AND sets credit for a replay score. I think this is correct because a match would never give you an extra ball.

What happens with the leds when you press diagnostic button the first time? The self test needs to pass before you can enter data. Have you verified the data in test 4 after setting it?

this seems like a vital clue. So you can verify the values in test 04 like later MPU versions you just can't set them that way?

That's what the manual says. It's been a while since I had stock software in my system 3 hot tip so I can't remember precisely, just that it was a giant pain

The manual on IPDB does not contain this information

"What happens with the leds when you press diagnostic button the first time?"

The 2 LED's on the board flash twice, very quickly.

"Have you verified the data in test 4 after setting it? "
No clue on how to do this

Refer to the hot tip manual, I think it should work the same

Ok, I might be making progress I'm seem to be able to set everything....EXCEPT I can't set the Play Adjustment (this setting includes the number of balls per game....#18), For some reason, the setting I put in doesn't "stick". And when I push the LOAD DATA button the LED's kind of "twinkle", rather than the quick flash they do for the other setting.

TEST 04 show it to be set at 13, and I've been trying to set it to 05

Going to try replacing IC 19 (with NVRAM) and see if that fixes it.

NVRAM seems to have fixed the problem...that, and going through the correct programming procedure
