I might hang on to the power supply for a spare as I have a Sinbad as well but you are welcome to the MPU and Solenoid boards.. I am happy if you just cover postage costs or free if you are on the Gold Coast and can pick them up..

The MPU powers up and plays but has issues holding memory etc and behaves as if no batteries are in place to hold the high scores, been tested and it's one of the spider chips apparently.
The solenoid board powers up and works fine as I was able to play the game ok before the resto and all solenoids were working.

PM me if you want to go ahead with it..

Cheers: Brettski... :)
