It looks like there is a three axis servo indexer that accepts step & direction inputs and three matching servo amps with motors. And the first two boxes look like a power supply and frequency drive for the spindle. I think you could make them work, if you can get specs for them. Also rack & pinion, ball (or lead) screws, linear guides, etc....
Better get them out of the weather. Pull everything off and inventory. Sell what you dont need on eBay. Looks like it may be a good start to me.
