Yes. You can still obtain System 6.0.x on 800K disks through any authorized
dealer. Macintosh System Software 6.0.8 is the latest version of System 6.0.x,
and it is available on either 800K or 1.4 MB (high-density) floppy disks.
Remember that the files on these disks are organized in a special manner. You
cannot simply take the two high-density disks containing 6.0.8 and spread the
files randomly to four 800K disks. This will not work. You must have the
System Software version 6.0.8 disks that are intended for the 800K format.
These are labeled "System Tools," "Printing Tools," "Utilities 1" and
"Utilities 2."
