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 settings. 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.
