Software C47

ZIP archive containing the C47 distributions for the SwissMicros DM42 and DM42n calculators and Windows & Mac & Linux (simulator). (Note that the C47 on DM42 (Not DM42n) software should not be used from the gitLab distribution as that compile is restricted. This is the correct version on this site.)
