[Coco] MPI Update

[Joe Grubbs]

Hi Jim,

I assume you're talking about hearing noise through the CoCo's RF or Composite output to the TV/Monitor, correct? If so, I just tried my Orchestra 90/CC through my stock MPI on a CoCo2 and heard no abnormal noise, even with the volume on the TV cranked all the way.
