Per the previously referenced page in the 71 Owner's Manual, TEXT files "are formatted to be read by other Hewlett-Packard computers, such as the HP-75", which would imply they are LIF1.

So don't do that. I use HPDir to copy DOS text files to/from LIF images with the -c option to perform the conversion. I also use HPDir to copy binary files to/from LIF images (see Post #2). You can experiment with this technique without a PIL-Box by using Emu71 and ILPer. Dave |
