So, I'm planning out a Mimeo build, and need to decide how much grounding to do, and where to connect everything up.
It looks like most people just use a 2-prong AC connector and mount everything on wood or plexi, so there's just a signal ground, no chassis ground to speak of, and no earth ground.
However, I'm thinking that's not the best bet, and proper grounding would be a good idea.
There's a few possibilities here, which could be combined as needed:
Connect motherboard power pin 6 directly to earth ground
Ground transformer cores
Mount everything on a conductive surface (with standoffs, obviously) - could set up ground loops, though, which would be Bad News(tm)
