Actually, it is NOT a Massbus controller; it plugs directly into the SBI and EMULATES a massbus. Herein lies the gist of DEC's suit; does this constitute infringement of the MASSbus patent? I don't know anything of the legalities involved, but I'd bet that SI is saying that the specs are public and emulators are not infringement, etc. Anyway, the guy from SI told me that they have two 780's and a 750 out in california; one 780 for internal DP and the other two machines for development. The 750 Massbus emulator should be out in the spring. I believe it's safe to say there are no other foreign massbus controllers on the market right now.
