Quick Summary
Use the British System 7.0.1 utility disk image to convert the North American Macintosh System 7.0.1 Self Mounting Image into image files that Mini vMac can use.
(Self Mounting Images require System 7 or later, and the System 7 installer from Apple is a Self Mounting Image, which makes things difficult. So the trick here is to use the British System 7, which is available from Apple as Self Extracting Archives that work in System 6.)
Ingredients
The "BrSys7Ut.dsk" disk image file, from the "British System 7.0.1 utility disk recipe".
