Was supposed to be a regular mailbag with multiple items, but this Haasoscope Pro was a 1.5hrs of raw footage adventure I have edited down to 45min, warts and all. So no other items, just this.
TLDR; This open source 2GHz 3.2GS/s USB Oscilloscope needs a lot of work...
This is not a full review, it's Mailbag, and is basically me documenting trying to sort out all sorts of issues.

The world's first desktop personal computer wasn't the Apple 1 or the Altair 8800. It wasn't even the HP 9100A, it was the Olivetti Programma 101 from 1965! Computer Teardowns don't get much more vintage than this.
