 * DL #1: This is the original English released Macintosh System
   Software 7.1.2 for the Macintosh LC 630 and Quadra 630 as it was
   first shipped in 1994.

 * DL #2: CD as ".iso" image in StuffIt 5.5 ".sit" archive, It's the
   same English version as the Top DL, but size corrected, as the
   original 650MB CD dump is approx. 500MB after compression, even
   tho' it contains only 50MB data inside.

 * DL #3: This is the original French released Macintosh System
   Software 7.1.2 for the Macintosh LC 630 and Quadra 630 as it was
   first shipped in 1994. As ISO image in a zip archive.

 * DL #4: CD as ".iso" image in StuffIt 3.0 ".sit" archive, It's the
   same French version as the 3rd DL, but size corrected, with the
   empty disk space removed.

Compatibility
Architecture: 68k

As it is machine specific, if installing this to Basilisk II, you need
to start up from a bootable disk or Disk Tools floppy image, known to
be able to boot up OK into Basilisk. Then you can run the installer to
install the system from the mounted 7.1.2 image, to a hard drive image
(and not the disk image you booted up on).

On Basilisk II, for me this installs as System 7.1.1, not 7.1.2 ?
don't know why it does this. YMMV
