HP 54845A Oscilloscope Repair - Part 1

I’ve been tryign to egt a working, in calibration 1GHz scope for some time. I recently bought several scopes in various states from an online auction working on the theory that I have to be able to get one of them to work. This video is the first part of the repair journey with the HP 54845A scope - In it I get the drive fixed and the device booting into the scope software. Part 2 is here - Hybrid Cleaning here - Note: The basically unedited video is located here -
