No, it's a boot loader ROM ("CBL" is Communications Bootstrap Loader) that
will load absolute programs across a DS/1000 link. So it's one of the
small PROMs that mount on the CPU board and that is invoked by the front
panel IBL button. It's used to bring up a memory-based system node by
loading the OS from a disc-based node across the link.
