I don't have one of these (yet!), but from a thread a few months ago
(message no. 8819 etc.), I believe it is a CEM3379 chip, as also used
in the 109. I was disappointed in the week not to be able to pick one
of these up (the UK distributor had run out), otherwise I would be able
to give you a more definitive answer!
