Update:
I was using one of those tape drive extender cables so I could easily swap
the cables between my 8" drive and my normal 3.5/5.25 drives and it was
missing pin 2. I connected the 8" cable directly to the controller and
now I'm getting slightly different results.
When I now try to load any sector from debug I am getting a sector not
found error.
I downloaded a utility that shows the RPM of the drive. With the DOS
formatted disk in the drive it shows the RPM at 360. If I put in either
of the NEC CP/M or DOS disks, it errors out.
