	At the moment we have at least 50 PC compatible's, running
	MS-DOS, that are networked together on an ethernet. We have
	three types of ethernet boards that we use on the PC's:

		1 - 3COM 501 and 505 card
		2 - EXCELAN 8051-01
		3 - Western Digital

	This are cards that allow you to hook up the PC directly into
	the ETHERNET using a 15 pin transceiver(ethernet) cable or using
	cheap net (coax or thin-ethernet) wire. 

	These boards can be installed in any of the expansion slots 
	that are available in your PC. 

	The 3COM 501, 505 and Western Digital boards work with the FTP
	Software PC/TCP Network Software. The PC/TCP programs are a set
	of commands that operate under MS-DOS or PC-DOS 2.2 or higher.
	These programs provide a set of facilities that make the PC
	look like a network host rather than just a simulated
	intelligent terminal. 

	EXCELAN has its own software for each of its boards as far as I
	know. 

	Our scenario in our LAB is as follows:

	We have a single logical ETHERNET with gateways
	both to the Defense Data Network and the OSI Network (OSINET).
	The logical LAN is composed of three seperate physical segments
	in each of our three buildings here at the Navy Yard. Each of
	the LAN segments has a SUN workstation running BSD 4.2 UNIX as
	a local server and a bunch of PC's, Zenith 248's, that are
	attached to the LAN. The LAN segments are connected with
	intelligent protocol-transparent ETHERNET bridges. 
	
	We have a MACINTOSH with an EXCELAN card that we use with the
	NCSA Telnet TCP/IP software ($20 per copy).

	We use our PC's regularly to get to our SUN's and we also
	connect to other hosts out in the network. If you have any
	other questions about this give us a call. Hope this helps
	you!!  : - )
