Exchange programs from a "11C" calculator to a Windows or Android emulator is possible

with a single calculator model: the DM11 (DM11L or DM11C)

and with the NutEm/PC emulator on Windows

and with the Touch RPN 11C emulator on Android.

The other HP-11C and the PX11C calculators unfortunately cannot communicate with a PC and exchange data, apart from updating the firmware .

	the interface
		The PH11C interface allows to generate : either dumps from HP-11C source programs saved in *.TXT* or *.11C files* or HP-11C source programs in *.TXT* from DM11L or DM11C dumps saved in file *.D11. The dumps are exchanged with the DM11L* or the DM11C using a *USB* cable and the *PuTTY* program .
