These
are disk images of very old original Macintosh software that worked on
Macintosh computers that were in use many years ago. I've provided
three disk images. Two of them are 400 K disk images and one of them
is an 800 K disk image. The picture is taken from the 800 K disk
image. That's why it shows 441 K of space remaining even though the
software was originally provided on a 400 K diskette.
It takes a very old computer to mount a 400 K disk image. I was able to mount both of the 400 K disk images using an old Mac Classic, running System 7.0.1. Each of the disk images required a different version of Disk Copy. Here are the versions of Disk Copy that I used for each of the versions of the 400 K disk images. I encountered occasional error messages during the processes but the processes worked and the images were mounted successfully.
Backup Disk.image (400 K disk image)
I mounted this disk image using MountImage 1.1b3, which came with Disk
Copy 4.2.
Backup Disk 1985 400k.img (400 K disk image)
I mounted this disk image using Disk Copy 6.1.3.
You should be able to mount the 800 K disk image using whatever version of Disk Copy will run on your computer .
When you download the stuffed archive, you'll probably get error messages regarding the 400 K image files. Send the stuffed archive through your local network, or transfer it on a diskette, to a computer that's old enough to recognize Macintosh File Structure (MFS) and unstuff it there.
