"The NetPICT Disk" is the companion disk to the book "Live Wired",
which you can read here:
[https://archive.org/details/mac_Live_Wired_Networking_Made_Simple_1993/m...][1]

It comes with a whole bunch of PICT files showing off stacks for
various Mac networking hardware, software, and protocols.

It also comes with a HyperCard stack that supposedly lets you view the
PICTs, but I couldn't get the stack to work properly, so instead I
used MacDrawPro to capture a screenshot with some of the PICTs open.

Compatibility

The HyperCard stack requires any Mac that can run HyperCard 2.1 or
better. The PICTs themselves can be opened directly using any Mac.
