IIRC, the contents of the ECB while it is "actively" (so to speak) being waited upon ​contains the RB address (in the home address space) of the task which is currently doing the waiting. Which is one reason why multiple tasks cannot wait on a single ECB. It is also one reason why RBs must continue to reside in 24 bit storage. And is yet another reason to "prefer" using "more advanced" facilities. -- The unfacts, did we have them, are too imprecisely few to warrant our certitude.
