We have a similar problem. We want to get all of our machines on campus to talk. Fortunately, except for our IBM-compatible system (an AS-9000, roughly a Hitachi version of a 3081), the rest can handle TCP on Ethernet. So the obvious solution is to put TCP up on the AS-9000. We believe that this is possible. It appears that IBM is now selling U. of Wisconsin's TCP/IP implementation for VM. Last time we checked, it used a Unibus Ethernet interface, hooked into the IBM machine using an IBM channel to Unibus adapter that somehow involved an IBM PC. We had some hints that this might be slightly slow. For MVS, the UCLA computer center has a TCP/IP implementation. As far as I know, it currently supports only a real Arpanet (i.e. 1822) interface. ACC is currently under contract to us to build an Ethernet interface for an IBM channel. It will look like their 1822 interface to the IBM system, so that it can use the UCLA software unchanged. We found one or two other vendors who were about to come up with suitable interfaces also. The original due date for the ACC interface was January, 1985. It seems to have slipped to February now. -------
