I was going through a box of old floppies after getting a floppy drive for my Kanga and in it was this old 1984 copyright Macintosh System Disk which I believe was from a family member’s old 128 or 512K. I didn’t want to try to read it in the Kanga since I’ve heard of newer drives causing issues for 400K disks. It’s a cool find, maybe I’ll give it to someone with a machine that can use it.
