alt Hacker NewsNot sure if you saw it, but before doing the TDS7104, I refurbished two Agilent 54831 scopes: https://tomverbeure.github.io/2026/03/28/Repair-of-Two-Agile.... For the one that still had a HD, copying the image from to an SSD worked without any issues. However, I also had a 54825A where it didn't work (I sold it, no blog post about that one.) So it's clearly hit-and-miss.
I found the 32 screws of the TDS7104 less of a pain than the dismantling the Agilents which had less screws.

Yeah sliding the whole thing out of the shell and the (curses) front panel ribbon that gets in the way, and the best part is that if it pops out on the front panel end, the tab is held in place by a metal prong that you have to bend (break away) to undo the tab to secure the ribbon. The prong is not screwed down, it's riveted. Breaking that thing away was the best thing I could do without ruining the panel. I ended up also gluing that ribbon to the chassis so that it doesn't get caught again.
Edit: I also bought mine to use it, hence all the extra bits around it.
