I don't have the exact instructions, but I figure I'd paraphrase what I
remember about the procedure.

The speed-up is possible by copying the ROM console routines into RAM and
then changing the routine vector table to point to the RAM copy.  Since
RAM is faster to read than ROM, you notice a slight improvement.  The
tradeoff is that it ties down 256K of memory which could be used for other
purposes.
