Do anyone have copies of this.

I've never seen an 800K version.  That's pretty unusual.  I do not have a copy, even on my MacOS Anthology CD.

i must have a copy somewhere as i have it on my plus'es HD20 (floppy port version) and did not have another mac when i did it years ago.  Ill look, may take a while.

I've never seen this either, but if you want to make your own set, it's really not that hard.

You'll need a Mac that can accept high density floppies with a hard drive, the disk images from Apple's site, or a CD-ROM...and can also write to 800K disks.

You'll also need a ton of 800K disks, likely around 30 of them. (Always have a few extras in case one winds up being bad).

There is one last thing to get: a file compression program such as Stuffit or Compact Pro which can segment archives.

First, wipe the drive of the Mac that can accept the high density floppies. You'll want a clean install.

Install System 7.5 to that Mac. Try to install any option you think you'd want on an 800K Mac.

Now, use segment and join to create an archive of the install, set to 800K floppy size. To play it safe, customize the size to 700K.

You'll also need a boot disk for your 800K Mac. Use a minimal install of System 6. If you have only one floppy drive, find a copy of RAMDisk+ and copy your active system to a RAM Disk to free up the drive. (Don't worry about this if you have two floppy drives).

You now have a set of System 7.5 floppies you can use. 

Feel free to wipe the drive of the Mac with the high density drive now that you've made your set and return it to whatever system version it normally runs.
