I got lucky - the "broken, unknown state" oscilloscope I got off eBay that cost US $80,000 new only needed a $16 part replaced.
Feast your eyes on some pretty awesome screenshots. 
to the first person who knows and can explain the physics behind the first 2 pictures.

@wohali wow this looks much nicer than the (apparently better and newer) xp based lecroy we have at work
@wohali ohhh they used VxWorks?? This is such a step backwards 🤦♂️
@MightyPork wait! i was wrong. mine is actually a proprietary OS. the next 2 revisions ran on VxWorks, then they switched to the Windows XP/7 embedded PCs they use now.
@wohali how responsive is it? The xp one likes to randomly pause and think things over and crap like that, as you'd expect on old widows
@wohali (thanks autocorrect lol)
@MightyPork Haha, after changing specific settings it'll click a couple of relays and pause for ~1-1.5s or so. The user group jokingly calls this the "Walter LeCroy Memorial Second" :D
It's pretty good as long as you aren't crossing one of those boundaries.
FYI the story of them moving from the original custom OS to VxWorks (before moving to Windows): https://www.researchgate.net/publication/220220764_Re-engineering_at_LeCroy_Corporation_The_move_to_component-based_systems
@MightyPork thanks! this was the ~last generation of VxWorks based scopes. ~96MHz PowerPC 603e. It's a joy to use so far.
