Excuse me... but the way I understand it, it goes like this:  UCLA has
an ancient box that connects a 360/370/etc channel to an IMP.  This is
the box that the UCLA ACP was written to support.  ACC designed their
box to emulate an IMP (i.e., it speaks 1822) because that's the TCP/IP
software that was available.  I think the UCLA ACP is older than
Ethernet.  When the ACP was first written, it spoke NCP, not TCP/IP.
My first experience with it was in 1973 when there were 43 Arpanet
hosts worldwide.
