Who has an HP 1650B logic analyzer?

[9000 VAX]

After several hours of struggling with three of my HD drives and three
of my computers, I finally made the system disk and the 1650B booted
successfully. Thank you three again. Now I need to make one pad. I
heard that there are terminators in the pads. What value are those
resistors and how they are connected to power and ground? I guess if I
use short wires I would not need them. Am I right? I plan to use some
IDE ribbon cables. Any information is welcome.
