Hi,
Having studied digital electronics as a young'un, I've been programming in high level languages most of my career and now in my (almost) retirement I'm delving into the electronics a little more. I was just looking for a way to diagnose an old Dell laptop and came across your site quite by hazard.
What an Aladdins cave, I've stumbled into.

So thank you for having me, and thank you for the treasure!
