Thank you, Robert. This is actually what got me asking about the floppy controller working with the KenTon. I looked at my HDB-DOS, and did not find those utilities, but I did find this RGB-DOS image that I had previously managed to transfer to a .DSK image for CoCoSDC.

My problem was that the tools don’t run without RGB-DOS, so I needed a way to boot in to RGB-DOS and load the file from a DSK. I was just going to take the easy way out and boot to SDC-DOS, copy it to a floppy, then boot in to RGB-DOS and run it from the floppy. I finally managed to do that and used HD-UTIL (I think) which gave me the specs of my SyQuest SCSI.

I wondered about the FORMAT utilities but wasn’t sure how to use them. A few of these take inputs similar to what the HD-UTILS output gave me, but I did not get too fare with it.

I needed to identify the bad sectors, anyway, so I did that through B09, writing bad sectors in to a .txt file.

I will revisit these now that I understand what was going on with my MPI slot select. I should be able to use some code from Darren to mount a CoCoSDC drive while running RGB-DOS, so it thinks it is a physical floppy. At least, I think that’s what I did to end up getting all 255+ of my RGB-DOS disk images copied ;-)
