Good question! I'm a little curious about that too. I also remember (very
vaguely) seeing some 24" rack panels and such in some catalog, ages ago,
but I don't recall ever running into any hardware that used it.
Lots of big IBM hardware (and some other manufacturers - I think Sun's E10k
systems) use the 24" rack, like my S/390 gear, and these IBM SP racks I'm
working on...
I can't think of anything older than S/390s that uses the 24" rack though.
