Tecmar made a PC floppy controller that also supported 8" MFM.
There were jumpers for that, including the 500K data transfer rate.
Tecmar's 8" MFM format was not the same as the IBM 1.2M, nor the same as 
"Vista" nor "Maynard".

I don't remember the cabling.  It may have had a 50 pin dual row header, 
rather than cabling the 8" from the DC37
