CDC-114/Altos 8600 Xenix recovered files
In case anyone here is interested, I have finished reading and recovery of some 8" disks used with a CDC-114/Altos 8600 Xenix system.
I have posted the end results here: http://s000.tinyupload.com/?file_id=276 ... 1708425889
This includes two possible boot disks in ImageDisk format, (They require a FDC that can handle 128 byte MFM sectors), and four unix tar files. These mostly contain Xenix 2.2 8086 development binaries.

The TAR files were created by concatenating the data sections of an 8" floppy disk backup set.
Cdc114dg.imd "Diagnostics for CDC-114 20M":
This disk was archived using a Kryoflux, decoded with the PCE tools, and converted to IMD.
This disk image uses 128 byte HD MFM sectors, which requires a special floppy controller to write.
x22root.imd "Xenix 2.2b Root - for CDC-114 Altos 8600"
This disk was archived using a Kryoflux, decoded with the PCE tools, and converted to IMD.
This disk image uses 128 byte HD MFM sectors, which requires a special floppy controller to write.
Xenix full dump (7-10-1984).tar:
This appears to be a full backup of a CDC-114/Altos 8600 system.
There were a few bad sectors on disk 4 of the backup set, so a few files will be corrupt.
According to the label, archiving at disk 6 was "restarted" for some reason.
There are also some file names that can not be extracted on a Windows system.
Damaged files appear to include:
/bbqa/cdbc/io2.bb
/bbqa/cdbc/pf1.bb
/bbqa/src/kadd3.bb
/bbqa/src/lkadd2.bb
These are all business basic source code text files.
spar (5-7-86).tar
This appears to be an archive of a "sparse file archiver"
