If you are talking about ARPANET in the sense of 1822 or X.25 IMP (or
"PSN"; they're the same thing) interfaces, then there are a couple of
products that will satisfy your requirement. I suggest that you contact:

	Proteon, Inc.
	Natick, MA

	Communication Machinery Corp.
	Santa Barbara, CA

	SUN Microsystems, Inc.
	Mountain View, CA

	Advanced Computer Communications
	Santa Barbara, CA

The first two companies make gateway products for connecting one or
more ethernets to the DDN (ARPANET or MILNET), and a SUN can also be
used as a gateway between DDN and an ethernet. ACC makes 1822 and X.25
host interfaces for lots of different equipment, and you can
concievably "roll-your-own-gateway" with their interfaces in
combination with some computer manufacturer's CPU (you mentioned DEC,
and either PDP-11s or VAX-11s can be used for this).

There is a file available for public FTP from the Network Information
Center (NIC.SRI.COM) called NETINFO:IMPLEMENTATIONS.TXT which contains
the names, addresses and points of contact for all known TCP/IP
implementations. It is large, but very useful.
