Pah, I was installing the quaintly named Transmission Control Protocol/Internet Protocol on IBM MVS mainframes back in 1991 before it was even an official IBM product for MVS.
Oh, and we used IBM-compatible PCs (remember them?) running Attachmate 3270 emulator, so arguably we had a graphical display too.
