MasterCATZ 0 Posted February 8, 2016 my dad now has quite a collection of now dead units that all seem to run the same software they just sit at the firmware loading screen I am assuming it's possible to TTL into them I can see a 4 pin header under the metal shield and have observed these markings on the board ( sorry no pics did not think about that before re assembling) RS-DM-202D was written externally on the board there was a chip on underside of PCB microwx vc0715sppv and through the holes of metal sheild I could read DAB SU 202D 1501 forgive me if i typed anything wrong my handwriting is terrible Share this post Link to post Share on other sites
