Getting these things up and running is no surprise to me. It seems that they used quality stuff in them days. I have loads of these oldies that haven't been booted for 10+ years and upon plugging them in they start off as if nothing ever happened. Drives with a ST-506 interface in particular seem to be of an indistructible kind of quality-make.
