7.5 and 7.6 are still not free from apple. I have 7.6 on cd extra if you want.

The 8600 will only run 7.5.5 (with System Enabler 702) and 7.6.1 - it will NOT run anything earlier and will NOT run 7.6.0
The 7.5.5 CD that shipped with the 200Mhz machine has a P/N of 691-1231-A (international version is prefixed with "Z" ie Z691-1231-A).
I can't recall if you can boot the 200Mhz 7.5.5 CD on a faster CPU card as later 8600s with faster CPUs only shipped with 7.6.1 CDs P/N 691-1623-A.
As previously noted, with 7.6.1 you won't be able to write 400K disks unless you use DiskCopy to write an image file to a floppy.
Can 7.6.1 do 800k disks?
7.6.1, 8.x. 9.x .. have no issues at all with 800K, or HFS.
7.6.1 will not write MFS, and 8 will not even read it.
800K on a 512Ke is going to be HFS. The determination is made when you select "Single Sided" or "Double Sided" at the time of formatting the disk. Single sided would be MFS. This is set in motion by the ROM and supporting operating system.
Useless trivia:
If you install an 800K drive in a non-enhanced Macintosh you get this really cool "rare" 800K MFS formatted volume.
Install Toast and drag the system folder and assorted other things to a disc, make it bootable, and save an image if you don't have a writer on that machine.
That way you can boot a CD from the installed system software if you have to setup another drive.
It may be moot now but a 7.5.5 original install CD has just been relisted on eBay:
