Images of floppy disks [mirrored from the Internet Archive][1].
Original page description reproduced below:
These are two distinct floppies that both contain the same version of
an Ethernet Driver for the Apple Macintosh.
Both disks have exactly the same content but I still uploaded both
because I think they are probably broken (the KryoFlux log files
reported multiple errors and the resulting image files look very
empty).
Maybe some usable data can be salvaged from them.
Also from inside the image files:
\- "Sonic Systems, Inc. Ethernet Series Release Notes. January
20,1995"
\- "This installs EtherTalk Phase 2 (version 2.5.4) and the Ethernet
driver for the Nubus/LC/IIsi ethernet card. If you are doing a custom
install, be sure to install AppleTalk version 58.1 as well."
\- "This installs EtherTalk Phase 2 (version 2.5) and the Ethernet
driver for the SE ethernet card. If you are doing a custom install, be
sure to install AppleTalk version 58.0 as well."
Compatibility
Architecture: 68k
From the image files I think it's supposed to be a driver for the
following devices:
\- the Centris 650, Centris 610 or Quadra 800 Built-in Ethernet driver
\- the Quadra 840AV Built-in Ethernet driver
\- the Centris 660AV Built-in Ethernet driver
