They're like kittens. You can't rescue them all. I've seen units worth more than $50,000 literally thrown
into the dump. I salvage what I can. In that case it was just the lenses and vac easel that I rescued.
And I know about doomed stuff worth way more than that. I've turned down all kinds of free enlargers. But ya gotta have space and need. Get the gear while you can, because it won't take long before the whole planet is buried beneath hundreds of feet obsolete electronics waste, and you'll have to dig way down thru all the crushed inkjet machines and last-year's techie toys to get to the good stuff.
