I was going thru my OS 4.2 Box and saw it contained a 4.2 Patch 4 Update CD.
I looked online and didn't see it archived anywhere so I uploaded it to the Internet Archive.

See it also has Next Step 3.3 Patches and Drivers on the CD as well.
What's the code on the inside of the CD?
CDs are retro technology now, Pretty hard to find blank ones in a store in New Zealand.
the letters stamped into the clear ring in the middle (as read from the bottom) is "IFPI2SO1"
