Install British Macintosh System 7.0.1 on a blank disk image, and then add the utilities ImportFl, binUnpk, and ExportFl.
This is useful for opening images in ".smi.bin" format (Self Mounting Images encoded in Macbinary). For some reason these images work in British 7.0.1, but not in North American 7.0.1, at least on a Macintosh Plus.
The 7 images from the "British System 7.0.1 install images recipe". (Actually only four are used: Install 1, Install 2, Tidbits, and Fonts.)
The "Blanks" collection.
The "Sys6Util.dsk" disk image file, from the "System 6 utility disk recipe". (For a quick way to get a copy of ImportFl, binUnpk, and ExportFl.)
Launch Mini vMac
Mount the image file "Install 1", such as by dragging the icon of the image onto the Mini vMac window.
Click the "OK" button.
Mount the image file "Install 2", such as by dragging the icon of the image onto the Mini vMac window.
Mount the image file "Tidbits".

Unzip the file "004M.zip" (in the "M" folder) from the Blanks collection.
Mount the resulting "004M.dsk" image in Mini vMac.
Click the "Customize" button.
