If you replace your 741 for a mosfet op-amp you can use drivewire for coco2 on a coco1. I did it.

I still saw the DOS command on the DECB screen.  The clear screen and "nitros9 booting" never took place.  If this runs in an emulator configured as a Coco 1, then something is wrong.  I think I have a Coco 2 that is upgraded to 6309.  I'll try a coco2_6309 dsk file on that machine and let you know.
