3M / A P Products have a couple of versions of DIP test clips - the
headless version and the nailhead version.
For logic analyzer use you generally would want to use the headless
version. The logic analyzer flying lead ends should slip directly on
top of the DIP test clip pins.
The nailhead version as the name implies look somewhat like the head
of a nail on top of the DIP test clip pins. That is to stop a clip
from slipping off the top of the pins, but it is a real pain to have
to try to fit clips on all of the pins in the space available and make
sure none of them pop off.
