I downloaded the Apple Mac OS 7.1 (Performa 200) (3.5-1.44mb) release. These are "image" files without extension. I am on a Win10 machine, I do not have access to any apple except the Performa 200. How do I install this?
@Planetdune You may find it easier to install Apple Mac OS 7.1 on Windows 10 using an emulator. The Basilisk ii emulator and Mini vMac emulator will both run 7.1 on Windows 10.
Do you have a specific need to install this on the Performa 200?
If so, use WinImage to write the 1.44mb images to 1.44mb floppy disks.
You may use a USB floppy drive to do this. Note that WinImage will not show you files inside Macintosh disk images. Also note that 400k/800k Macintosh floppy disks are not supported by WinImage or PC floppy drives.
