Probably only about 5% unless runb has been recoded.

Recoded can do some integer ops much much faster, only about 60 clocks to load 
the registers and do a 16 bit into 32 bit divide with a 16 bit answer and 
remainder put back in memory.  The 6809 will be 1500+ clocks to do that.  
16x16 mulls with 32 bit products in 40 or so counting the store back into 
memory time.

But I don't believe runb has been recoded.  A 1 byte patch is all I've heard 
of.

Robert or Boisy?  Clarify?
