So we have a customer who is currently running PCK2000 emulator on their MK1200s which they purchased 5 years ago to replace their old MK1000 price checkers.  now the MK1200 is EOS, we are trying to help them with a smooth transition into an MK500 and had hoped to keep using the PCK2000 software but it does not appear to run on MK500. has anyone else gone down this road, is there some tweak that might get it going on the new device and new OS? thanks, Afshin
