    Graphics support was provided by an IBM 5080 graphics system, a
    floor-standing tower. The 5080 was connected to the 7437 through the
    PS/2 via a cable and MCA adapter.[15]

    I had lunch with Jeffery Savit a few years ago. He works at Oracle now,
    long given up on VM. This is one of my favorite Operating System videos https://archive.org/details/AStrategicPointOfViewForVm.. seems IBM
    couldn't keep off the footgun with VM.
