I am trying to get a system image for my Mac128k onto a disk but have now way to format to 400k. Any suggestions, alternate routes, etc.?

I did some searching around last night after I wrote the thread and discovered that only an SE or older with system 6 will be able to do it. I have system 7.5 on my SE so I will have to come up with something. Maybe put the old 40 meg drive in and put system 6 on it, then swap back later, or I may be possible to boot into 6 with diskcopy 4.2 on the boot floppy.
Thanks for the replies guys.
If my tandy arrives soon, it may be longer.

Yes that was same page I got my info from, and I only need to write the image. Sadly I have no 400k floppies to do this, and my mac 128k is sleeping over at a friends house, so I'll have to shelve the project for a week or so.If my tandy arrives soon, it may be longer.

800k floppies (aka "DS, DD", or "Double Sided", "Low Density", "1.0 MB", or any other similar variation,) that are relatively common are 100% usable as 400k (or "Single Sided", or "SS, DD",) disks. This is because a 400k floppy is just an 800k floppy that you're only using one side of. There are no repercussions whatsoever to using an 800k floppy as a 400k floppy, as there are with using a High Density floppy as a Low Density floppy. You can safely format between 400k and 800k back and forth as much as you want.
I can't convince the Mac 8500 to do that, I put in an 800k disk and it just spits it out and says to use a single sided floppy. I have yet to try with the SE though
Druid--- I snagged a Model 100 with tpd off of fleabay.
I had some success last night writing the image on the SE. I still need to retrieve the mac128 to try out the image.
