Another nice little find today, and in very nice condition despite it's 25 years, the shop that it came from had another 2 Atari STE's along with another drive that I'm planning on going back for.
I have a few other Atari's that have/had problematic drives and have found a few guides to modify the motherboard to enable booting from an external drive.

So out with the solder station in the next few days, I think I'll choose one of the older spare machines first, just incase....
