When I left CA for NV in 2019 I sold the bulk of my IBM related stuff to the CMoA. It was a heavy Apple place at the time. My stuff moved Lonnie into the IBM world. The stuff filled the floor of a 26 ft truck. He paid for shipping. I then put together a half pallet of stragglers that he arranged for pickup. I went to the grand opening.
He had an archivist that was not an I.T. geek. Did many emails explaining what stuff was.
