You remember correctly. In fact, every CBM machine except the Amiga used
some form of it. (I *think* the Amiga didn't use it, but I could well be
wrong on that point.)

It never left; but CBM was the only company to design computers around it.
Otherwise, it was used pretty much exclusively for laboratory test
equipment. The reason being that, like SCSI, HPIB/GPIB/IEEE-488 requires
"intelligent" peripherals which are more expensive than dumb ones that you
can stick on a ST-506 or IDE or other interface that makes the main CPU do
all the work. (Commodore used a cheapened-down version of IEEE-488; it
wasn't quite compatible with the real thing, and had various problems due to
the cheapening-down.)
