I got BMOW's floppy emulator and have been pulling a bunch of files from 30 year old floppies (which have a miraculously low rate of failure) onto my SD card. One of the things I wanted to copy was a piece of software a friend and I made in high school. I was unable to copy it in Finder, which says "that cannot be duplicated or copied." When I did get a copy of the application off the disk, it wouldn't run without the original floppy disk inserted! I'm sure we thought we were very clever. Anyway, next attempt was going to be a disk image that I can run in an emulator.
But I'm having trouble creating disk image on my Mac Plus with 1 MB of memory. Disk Copy 4.2 tells me "there is not enough available memory" to image an 800 kB disk. I've been unable to find any other software that will run on the Plus, let alone make a successful image.
Are there any tools for imaging a floppy that will run on a 1 MB Mac Plus with System 6?
