[Coco] SDC's fixed; but not sure why?

That makes sense.    I can't believe I didn't catch that sooner. I spent so much time Re-seating the chips and cleaning the contacts while completely ignoring the jumper settings

That would do it.

No jumper is used for a DOS type ROM.  The autostart jumper would only be used for a ROM cart
style ROM executing in cart space. You don’t want the cart line triggering for ROMs that are an
extension of basic.

These pins are supposed to be jumpered to allow the SDC to run on the coco. I removed the jumper completely and now both SDC'S auto start to SDCX on powerup.
