So, I ran more tests and was happy to put back in the machine. The good news is it now boots, I get it to attract mode and it shows 4 default high scores to date as well as other messages. Looks good.
Lamps are coming on and look like they are in attract mode type of patterns - cant tell if they are right or wrong yet.
No sound - just a horrid hum.
The mechanism in the middle opens and closes - seems to be part of the startup of the machine?
Only the top 4 score displays are working - the bottom one - the smaller one is not lit at all.
I tried to start a game - it says its looking for a ball. 3 balls in the trough. Wont start a game, after a few seconds reverts to attract mode. Not looked under the apron, but looks like optos to detect the trough balls. Needs a closer look.
One time I did somehow get a game started. Flippers worked. The left slingshot switches, instead of firing the slingshot solenoid - they fired one of the pop bumpers. the right slingshot fired one of the other pop bumpers!!!
So, something wrong there - any ideas folks?
I am unfamiliar with williams games of this era, this is my first - trying to get into the test menu - 3 switches in the cab to left side just inside coin door. Advance and an Auto/Manual switch, and a third one. I cannot get them to do anything!
Checked the wiring they are wired back into the CPU board ok. Any ideas?
All the jumper plugs are in the right places, all plugged in ok. Wondering if we have yet more batter damage issues.
Pleased I've got it booting up though!
