What you've got here is a copy of a Proxim RangeLAN2 Wireless PC Card driver and the
NE2k wired ethernet driver (works with socket and some others - people may
already have this from the DDK) and the Newton Devices pkg required to run
them (replaces the shipped Newton Devices, users also need to load the
ethernet support pkg shipped with NIE 2.0).  There are a couple of
bugs with the proxim driver - they don't seem to stop it working except sometimes you get a timeout when using
Appletalk.
