Gould CSD went with IPI for its NPL line, expecting IPI to quickly
become popular. Unfortunately for Gould, SCSI came along, and peripheral
manufacturers chose to do SCSI first. For a long time Gould was just
about the only computer vendor that had IPI as the main I/O bus.
I think that Gould's disk controllers may still be the fastest IPI
controllers around (I don't think that it was Gould's intention to
get into the business of making them, but they had to).
    Lately, SCSI has been pooping out, and IPI has been picking up steam
again.
