A few years ago I found a RocHard A500 ram & HD expansion unit, in the original box, at a thrift store.
When I got it home and running I found the first -working- install of WordPerfect 4.1 for the Amiga I'd ever seen. After looking around in the WP directory for a bit I called the original owner on the other side of town.
He definately was surprised to hear from me. He had given it to a co-worker two or three years before. The fellow never told him he'd gotten rid of it. I assured him that I had no interest in his personal data. The phone call ended friendly.
