Reviving old thread...
I just purchased a used but nice Fathom -35 MPU to use as a replacement for my Space Invaders project. I know I have to rework the jumpers, but I noticed resistors at C8 C11 and C81 on the Fathom board where the SI board had small caps. Weird. Any ideas? Haven’t got to the point where I am ready to power it, but looking to avoid issues.
