I converted the vast majority of my Amiga disks into 1.76Mbyte SuperMagicom compatible disks by drilling a HD hole on the opposite side to where the write protect is.
Each weekend I'd be there in the garage with my dad's electric hand drill doing another 10 or so.
It wasn't until I got a HD for my Amiga and the tools to send the files over a parallel cable to the Magicom that the rest of my collection was saved.
What is unfortunate is that I mainly drilled Demo's and demo collections and kept the games. Today the games can be found as ADF files everywhere but the demo collections are rare
Like the entire EoC 1999 collection, all drilled and overwritten
