...finally, when you know your SE/30 and the "toolchain" works,
you can tacke these:
<http://download.info.apple.com/Apple_Support_Area/Apple_Software_Updates/En
glish-North_American/Macintosh/System/Older_System/System_7.5_Version_7.5.3/
>

  as you can see, there are 19 floppy image files: this amount of work is
only
worth doing when you know the infrastructure tho deploy them is ok.

good luck
