PDN Android Tablet- Specs confusion

[jamsit]

recently received a Pandigital Android Multimedia Tablet... box calls out R70E200 & 2GB memory.... however, tablet sticker calls out Mdl# PRD7T40WBL1, no 'R70.. number; tablet also shows Firmware v S64N_SLSB_OP15_PD_2011-03-01; kERNAL 2.6.27 & rdu V 2.8.1.5; Can someone explain what these items are(kernal;RDU...) & what the specs really are for this tablet?
