Test Equipment Porn: Hitachi V-509 Oscilloscope

This scope sat unloved and unused on a shelf at my old job for many years until they gave it to me. It sat on my shelf, then I gave it to my dad and it sat on his shelf. Then I took it back and it’s been basically unused for the last decade. Click on any image to see it much larger!
