How do you do this?

Using the TRANSFORM command. See the HP-75 Owner's Manual and p.8 of the HP-75 I/O ROM Programming Techniques Manual.

http://www.series80.org/Misc/HPILCMD.bin

The file is in HP LIFUTIL format (DFS to LIF file type preserved xfer type), which means that the first 256 bytes of the file is the LIF header.

Translation: The file is a standard LIF disc image compatible with ILPer. The issue with the image is that the filename is WS_FILE, not HPILCMDS and typically .bin is used for ROM images. ILPer defaults to .LIF and .DAT for LIF disc images. The file has also been recently added to the HP Computer Museum, courtesy of Bob Prosperi. http://www.hpmuseum.net/display_item.php?sw=489
