Hey Bernie!

According to http://www.ietf.org/rfc/rfc801.txt (NCP/TCP Transition 
Plan) - dated 1981
- Gary Grossman @ DTI had a VAX/VMS implementation
- Bob Braden had UCLA's "360 or 370" talking TCP/IP under OS/MVS and OS/MVT

In theory, there is no difference between theory and practice.
In practice, there is.   .... Yogi Berra
