I noticed that too. The datasheet clearly states that you can't switch 
directly from FAST to SLOW other than by a hardware RESET.  It says you need 
to first set R0 and clear R1 to switch to the Address Dependent mode, then 
clear R0 to switch to SLOW.  However on my CoCo 1 (also an F-board), I can 
just clear R1 to switch directly without any problems.
