The rack in this image appears to house a Texas Instruments minicomputer of some model, not sure exactly which. 980 maybe? Might be fun to play with, but not for $20K. https://images.squarespace-cdn.com/content/v1/5e52f79c0260e6... Note the 8" floppy disk drives also.
Even if it was free, it sounds like it’s going to cost more than that to move and house these things
At the minimum you’d need a telehandler or forklift capable of lifting 20,000 lbs (according to the listing) which is probably $1,500 for one day with delivery and pickup, a flatbed semi trailer to load it on, and labor to load it. If the equipment isn’t on skids you can lift with a forklift, then you need riggers and a crane truck. Either way sounds fairly expensive, and that’s without having a place to move it to.
