John van Bokkelen <jbvb@vax.ftp.com>, who is maintaining the spec.
Karl Auerbach <karl@trwind.trw.com>, who adapted MIT's PC/IP to use the packet
	driver spec and wrote a packet driver for the TRW-2000.
Phil Karn <karn@flash.bellcore.com>, who added a packet driver interface to
	his code, and supplied C code for the 3c501 and SLIP8250 drivers.
Bill Doster <Bill_Doster@um.cc.umich.edu, who wrote a NI5010 driver in C for
	Phil Karn's net.
Russell Nelson <nelson@clutx.clarkson.edu>, who created the packet driver
	skeleton and adapted several existing drivers to it.
Bob Clements <clements@bbn.com>, who wrote the WD8003E and 3c503 drivers.
Brad Clements <bkc@omnigate.clarkson.edu>, who adapted NCSA Telnet to use the
	packet driver spec.
(Bob and Brad are not related.)
The Wollongong Group, in the person of Leo J. McLaughlin <ljm@twg.com>, which
	has committed to supporting the spec.
3Com, in the person of Eric_Siegel@dsd.3mail.3com.com, has been helpful
	in getting 3Com's documention to packet driver authors.
Dan Lanciani <ddl@harvard.edu>, who wrote the 3c523 driver.
Denis DeLaRoca <delaroca@denis.oac.ucla.edu>, who added hardware handshake
	to the SLIP8250 driver.
John Grover <JGROVER@maine.bitnet>, who optimized the SLIP8250 driver to
	work at 38.4 Kbps.
Rainer Toebbicke <RTB@CERNVM.bitnet> who wrote the BICC Isolan driver.
Jan Engvald LDC <xjeldc@gemini.ldc.lu.se>, who improved the wd8003e driver,
	and added MicroChannel support.
Krishnan Gopalan <gkrishn@eng.clemson.edu> and
Gregg Stefancik <wstef@eng.clemson.edu> of Clemson University Engineering
	Computer Operations, who wrote the packet driver for the 3c505 card.
Vance Morrison <morrison@acns.nwu.edu> added starlan support to the wd8003e
	driver.
Brian Fisher <fisherb@qucdn.queensu.ca>, who wrote an "Ethernet" packet driver
	for the IBM Token Ring Adapter card.
Eric Henderson <eric@dcsprod.byu.edu> of Brigham Young University, who wrote
	packet driver for Novell's NE1000.
