OK, so I revert to a backup BlueSCSI image and that's the same. My SCSI disks are present, but not booting from disk, only ROM. I replace the CMOS batttery, do a reset and add the drives back, That's a nope. I shift the boot files to the IDE drive and tell that to be the boot drive. Doesn't work from my physical SCSI drive either. That's a nope too. WTF...
OK, so I stop work on the Archie and head over the the BBC B and install the 1770 FDD adapter kit:

Instructions followed to the letter and the machine boots fine and the DFS rom shows up, and I attempt to format a disk in both 40 and 80 track mode since the drive I have supports both via a switch at the back and I now have access to the FORM40 and FORM80 commands that I was missing before from the Cumana disk.
But I get this:

I tried both drives, both track settings and a different drive cable, but the answer is nope. Whilst I'm scratching my head, I hear screeching from the Archie, like it's in pain and I see this on screen:

And it's totally unresponsive. Bloody Acorns.
I don't think it's CMOS thats bad on the Archie, but I am wondering if it's bad RAM, so I may pull the RAM expansion and see what it does then. Need to swap some jumpers for that IIRC.
So the Cumana drives don't seem to be working, I get disk spin, and depending on the disk sometimes head step. I think I need to pull out a Gotek and try that with some BBC disk images, see if it's the drive.
Meh!
