 ## Architecture
 
 1. Are registers N, P, Q, K, F, FA memory-mapped?
+   (I have found no evidene of this being the case so far)
 2. If a program manually raises the flag for sequence 0, from where
    does sequence 0 begin executing?  (See also the question about the
    TSP and index register 0, below).
