[Coco] Nitros9 boot disk

[rietveld rietveld]

I am hoping one of eds mini mpi,s will  solve the 'y' cable issue by letting me select the controller (disto or SDc) ‎. I hope the MPI will let Nitros9 see only the SDC at bootup

If I remember correctly, a Y cable doesn’t like having two pieces of hardware at the same address (which a floppy controller and the CocoSDC, since it emulates one, would be), so they will argue with each other as to who is supposed to respond. Y cables were more meant for hardware at completely different addresses (and fully decoded).
