Anyone have docs/jumper settings for Tecmar "PC 500K/1MEG FLOPPY CONTROLLER" ISA card ?

I have one of these, it has 2 jumper blocks, JPR2 (4 3 pin jumper
'settings'... looks to probably latch each of the 4 high or low) and
JPR3 (12 on/off jumper positions).
It also has a JPR1 which would be a 3 pin header and it is strapped by
wire to position 1-2.
Would love to figure out how the IO port and IRQs are configured. Card
has no BIOS, so unlike a WD1002A-FOX there won't likely be any jumpers
to set drive type. (I'm not having much luck with that card in a Tandy
2500 SX... but that's a completely different issue).
Hopefully someone has or knows where there are some docs on the jumper
I'd imagine I could figure out some by probing which ISA pins various
jumpers connect to..... but any jumper settings that control chips for
decoding logic will be far more difficult to determine.
