Well, I finally ordered a BitScope Micro from a local reseller. Unfortunately, the reseller did not offer the probe kit(s), so it looks like I'm going to have to find that part elsewhere. I can get probes from Amazon pretty easily, but the probe adapters from Bitscope will have to be sourced somewhere else.

However, this is a major step in the right direction. The direction where I find out if the LCD display board is totally toast, in which case this work gets a lot harder.

But I'm glad I finally got this piece of kit. It adds a lot of basic functionality to my shack in a small package. Maybe I'll post pics of the signals I capture, assuming I can figure out how to make all this stuff work.

The irony is not lost on me that the device I just bought is orders of magnitude more powerful than the dinosaur I'm trying to resurrect.
