Ran out of fuse clips last night so parked the rebuild of the rectifier board for the night and moved onto the M-200 MPU

Board powered up in the Machine gave a solid LED light, so i've pulled it out and powered it up on the bench with a modified PC-PSU to run some diagnostics.
Preliminary tests on the CPU pinouts suggest the VMA voltage is too high and is an issue.
CPU
Pin40: Rest - 5.28V
Pin03: Clock - 2.52V
Pin36: Clock - 2.60v
Pin37: Clock - 2.60v
Pin05: VMA - 3.68v ..... should be 2.8v

I dont have a logic probe so am limited to what i can test - so any advice or pointers would be helpful
Thanks all !
