This drive it could replace punchcard, you could just have one of these hard discs. Of cards is you have to sort through them, compared to a disk drive you can go right to the information you need. It is much faster. Wellmade its so still functions. We have a team of volunteers who demonstrated once a week. There is 70yearold data still on the drive.
