I've always been worried about aging magnetic media. Late last year, my faithful oscilloscope didn't boot up. Fortunately, I had multiple copies of the system discs (the OS lets you make copies of a disc), so I was able to get it back up, and I made a new copy. But I was worried. I finally got a Gotek to replace the aging Sony MP-F52W-30 drive, made an adapter to interface the HP's Sony-compatible cable with the Gotek (there are some instructions here and more details here). Getting the disc change connection working was the hardest. It turns out that while my SFRKC30.AT3 Gotek looks from a distance like an SFRKC30.AT2 Gotek, it exposes the PA14 pin in the same place as the older SFRC922, and so on the AT3 one should follow the older unit's instructions.

I was now able to use HFE files (which are a complicated file format that handles all sorts of non-standard discs) on a flash drive to boot the oscilloscope. Yay! To this day (January 17, 2027), I still haven't been able to get direct image files to work, though.
