I know of no gateway that one can plug in and run between
a TCP/IP network and a Hyperchannel.  If you can obtain
TCP/IP for the IBM and/or the Sperry (they do exist), then
you could make one minicomputer a gateway by giving it an
interface on both the Hyperchannel and the other TCP/IP
networks.  Here at BRL, we have a Hyperchannel connecting our
CRAY to a Gould PN6000 which is in turn connected to the
building Ethernet.  The Gould runs UTX2.0 (4.3BSD) and acts
as the IP gateway between the Hyperchannel and the Ether.
The key is getting the same protocol suite on both machines.
