might have to make a blank Zac MPU after the Bally one..... 
LOL!!! Go for it Mike.
Ive got no choice but to tackle this corrosion... my problem now is if i do all this work and the CPU still does not boot then i cannot be sure that its still not a corrosion fault...

But!!! Had i spare blank Zac board.. then guess what my next job would be?... and made with confidence that all is complete.
