I have one of these, it has 2 jumper blocks, JPR2 (4 3 pin jumper

It also has a JPR1 which would be a 3 pin header and it is strapped by
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

I have manuals for the Tecmar PC-Mate Floppy 5/8 and also the SASI
adapter that was part of the PC-Mate system. Not sure if this is the
same Tecmar floppy adapter it is a full length 8 bit ISA card with a 50
pin connector at the rear of the card and two 34 pin edge connectors at
the top near the back for 5.25 drives. The floppy controller chip on it
is a UPD 765.
There is also a manual for the Xebec S1410 SASI to ST-406 controller.
