Now we're going back. I can't recall if it was a SCSI or MFM interface, but you may find an old PC that still has a ISA (16?) bus. If so, it should be pretty easy,
especially with a disk recovery program. ie RSTUDIO r-tools tech
In cases where the hardware had failed, we used to use a chemical to "stain" the magnetic material, then high res photograph it. Someone had a program
that just re-encoded the headers etc, Most / all of the professional data recovery companies use that technique. On those large platters and such low data
density, it is quite easy.
