Oohhh.. which Altos would this be ?  I'm looking for Xenix
for my Altos 886.

As I understand it Altos Xenix (for the 886) at least was quad
density disks.  80 tracks, double density.  Should be able to
image them using a 1.2M 5.25" PC floppy as long as software
can understand the format (I'd think it should do it anyway).
