Anyway to add memory to a Boss RC-20?

[davesisk@ipass.net]

Hey comrades:

I recently picked up an older Boss RC-20 (roughly 5 minutes of sample 
time). 
I'm just curious if there's any way to add more memory to it.  I'd imagine 
the
storage is some flavor of flash memory on a chip or card, although I 
haven't
opened the pedal up to see.  Does anyone have any ideas if there's any way 
to
do this?

Thanks and best regards,
Dave
