[Coco] CoCoSDC and Extended ADOS3

[Brett Gordon]

Ron,

I would start eliminating hardware.  Something's amiss.  Try flashing with
nothing more than the SDC in the cart. Maybe try different coco's too. I
started getting weird ROM errors and various glitches, during last
CocoFest(C) - I half pulled out the CLPD, reseated and everything worked
again.
