Thanks for the great tips I will have give it a try next week. On the dip
clamp is the name Continental Specialties but the unit itself has the name
Global on it. Serial number 224030

Now here's a Funny Thing: I have a Continental Specialties LM-2 logic
monitor with exactly the same features... you have the big 14-pin DIP
clamp with the LEDs and the designator strips, as well?
Mine came from a long-ago swap meet, and most likely both our manuals
are hiding in the same place... but it's pretty intuitive how it works..
you dial up the family, attach the red and black leads to GND and +V,
attach the clamp to the DUT, and watch Das Blinkenlights. I've used
several times to repair vintage Stuff.
