Before you two motherboards: RevoPlus, you can see above, and Revo Classic (below). They look like, is not it?
Motherboard Revo Classic, an image that you see - one of the earliest versions, she uses to reflash the flash-memory (suddenly employees Psion mistake :-)). Later, when production has reached full capacity, flash-memory chip has been replaced nepereproshivaemym (Masked Rom). Normal motherboard Revo Classic is more like a Revo Plus, thanks to this change. The most obvious difference is the Revo Plus another 8 MB EDO RAM.

(Now, when my hands hit model Revo Classic, I can make a more accurate comparison.) At two locations on the motherboard used Revo-mounting, it is made to overwrite the Flash-ROM'a, or my Revo was a test device.
Contact dynamics have also been small upgrades. In principle, they have remained the same, but one of them on the board Revo Plus added two extra "pads." It's funny, but they are not used, is likely to have added to prepare for the modernization of the speaker.
Physically, the two models Revos do not differ from each other, the improvement is to integrate the software WAP-browser and Opera.
