These disks are from the archives of GUFIH, a French user group for Heath and
Zenith computers. All of them are 8" backups and not originals, hence why I
didn't scan the labels.

Disk attributes:
* 3000/5000/8000:
  * 2 heads
  * 77 tracks per side
  * 5 sectors per track
  * 1024 bytes per sector
  * MFM encoding
  * HDOS disks
* 1200 and CPM85:
  * 2 heads
  * 77 tracks per side
  * Side 0 track 0 has 26 sectors of 128 bytes each (FM)
  * Every other track has 5 sectors of 1024 bytes each (MFM)
  * CP/M disks
* CPM86
  * 2 heads
  * 77 tracks per side
  * Side 0 track 0 has 26 sectors of 128 bytes each (FM)
  * Every other track has 26 sectors of 256 bytes each (MFM)

Images were done with a Greaseweazle, and exported as such:
* .hfe = HxCFloppyEmulator format, contains flux info
* .img = raw sector contents, CHS
* .imd = ImageDisk
* raw.zip = raw flux dumps per track
* label.txt = what was written on the label

You can convert from .hfe to any format of your liking through the HxC software.
