I have a question how do I set the address (HP-IB) of it?

You use the switches on the back see page 3-6 in the manual. Switches 1-5 set the address and 6&7 set the operating mode. You will likely want to set it up for addressable mode 6&7 = 1, in talk only mode it send out the date and time string 40 times a second and can only be set from the front panel.

Switches 1-5 set the address in a straight binary progression with switch 1 being the least significant bit, for instance mine is set to address 18 so switches 2 & 5 are in the 1 position. The ASCII talk and listen addresses are not relevant for using it with a 85. Both of my 59309s have a label on the bottom showing how to set the address.
