Dataflyer SCSI+ 4000 jumpers

[Motormouth]

What are the two jumpers on the dataflyer scsi+ 4000 do?

I am guessing that one has something to do with on board termination.
Is this correct?

I know this controller is as slow as molasses in January (July for you in the southern hemisphere), an is non-autobooting, but could come in handy in a pinch.

Hi.
If you want to trade it for another SCSI card i have a couple.

Thanks for the offer, however I do have several other SCSI cards around.  Even though the SCSI+ 4000 is sllllooooww, limited to PIO of the IDE controller,  it makes up for in convenience.  It is small and unassuming in an a4000, doesn't take up a Zorro slot and can be made to work (with adapters) with the a1200 and a600 even.  If you need data from a SCSI device, it can get the job done albeit with limitations.

Still I wonder what the jumpers on this card actually do.
