ALTERA PL-ASAP2 MPU - LP6 Vintage ISA Card Question ??

Hi Folks,

I've recently acquired a Vintage Altera LP6 Logic Programming card and the PL-ASAP2 MPU setup with the Adapter Base and a series of different adapters.



I have successfully interfaced it to an old computer and got the unit to function with the MAXPLUS2 Stand Alone Programmer software....
so all is well.

My question lies on a set of Jumper pins on the LP6 card and I am curious to their function.

The Manual makes no reference to them but I would like to know what their purpose is. I'm hoping someone here may have used one of these LP6 cards in the past and could shed some light on the subject.

The Image Below shows the Jumpers in Question. They are located beside the ISA BUS address Dip switch box. The Jumpers are Highlighted in Light Blue.

So if anyone by chance has any information on these Jumpers, please let me know.
