From memory, there are 3 versions of the logic board
used in the RL01.  
The first oen is RL01-only, the other 2 can be used either in an
RL01 or
an RL02 with a jumper change. The last of those has many more testpoints
than the earlier one.  
 
 yup.  I was just looking at this today.
   54-12175 RL01
   54-13531 v2 (RL01 or RL02)
   54-14025 v3
 I don't know about the v3 board.  It may do them both also.
