Would a Greaseweazle :
https://github.com/keirf/greaseweazle
do what you want? It links to a standard 5.25", 3.5" or 3" drive with
a plain cable and with a simple wiring adapter to an 8" drive. Plugs
into a USB port which powers the Greasweazle microicontroller but not
the drive (of course)
It works at the flux transition level and can produce 'raw' files of
the timings of said transitions. The standard software will also
encode/decode FM, MFM, some GCR, etc disks.
I second the recommendation (and the caution). I have not found a disk format
it will not read, but you may have to do a little work in advance to write a
diskdef if you want something sane. I have successfully used one with a regular
PC Teac 3.5" and 5.25" mechs, but also a DEC RX50 and a CDC 5.25" drive
from a 3B2.
