Hi, and thanks everyone for the welcome,,,
I've had the firepower for only a few weeks, and its proving to be a bigger project than expected.
A lot of issues with the MPU and driver board that need attention, so waiting for components to arrive.
Besides that the old girl has done a million miles, and I have worked under the play field bringing it upto standard.
The cabinet is in top condition and why I feel its worth spending time ironing out the bugs. I think.???

 I have been reading a lot in the technical section here trying to understand the common circuit issues, and it sure is overwhelming to say the least.
Will keep reading and studying the circuit diagrams until it all clicks.
Just can't wait to get it working right as it will bring back a lot of good memories.

Regards Phil...
