Wire a HP-41 handheld computer with IL-Module to the HP-IL/PC Interface Card, switch ON the handheld, SF 15, AUTOIO and execute DIR = CAT 7 (CCD-Module). Now the handheld is scanning the virtual Interface Loop of EMU41, finds the HDRIVE1 and lists the files. During the ON mode of HP-41 the calculator mode of Emu41 is deactivated (because only one loop controller is possible). Transfer some program files from HP-41 main memory to HDRIVE1 with WRTP command. Switch OFF the handheld. Load the programs to EMU41 main memory by executing READP. Now CAT 1 lists the uploaded routines in EMU41....
