SM Lite P11's speed = 2 MB !?

  1. Does anybody have some description of the platform P11?
    2. We think that the devices SM Lite platforms P11 have the speed 2 MB and not 512 KB – is it really so?
    Can the old SM Lite be upgraded to 2 MB without using the Prizm?
    We tried to do it with the Soft 9.5, but it didn’t help.

I thought they discontinued sm lites? You do need prizim to use the feature keys to allow for faster speeds and can not be permanently changed the a regular unit.
