Picked up a second hand SUR40 surface table and managed to (somehow) get the factory image from Samsung. Right now ive just deployed the image and am playing around with the base functions.
The main goal is to try modernise the unit, with some basics. ie ram, hdd and OS. When I cracked it open the mobo, gfx, screen and input "visualiser" are all hardwired to each other so im going to be looking into either reworking the guts to accept newer hardware OR sending the touch inputs to a beefier remote machine and send the display back to the surface.
