There are two utilities, one is called LIFUTIL and was initially
There are actually at least 3 :-)
sold by HP. This runs under MSDOS and allows floppies
to be read
(and even written).
You can get a copy at:
ftp://ftp.math.jyu.fi/pub/hpil/lifutil
The second utility runs under Unix and allows access to disk images
(i.e. the contents of the floppies after you have dd'd them to a
Unix system). I have written this utility myself to help me xfer stuff
from my HP-85 to my OpenBSD web server (
www.series80.org).
The third is my 'LIF Utilites for Linux'. They're still very much under
developemnt (at the moment, you can read files from a LIF disk on the
linux box, but I've not written a program to write individual files back
to a LIF disk yet, for example). You can get them (C source, GPLed) from
the HPCC web site,
http://www.hpcc.org.
I wrote these prrograms to work with the 9114 LIF disks used on the HP41,
71, and 75 calculators. I can suggest modifications to work with other
types of LIF disk (I know of somebody who read some HP high-density disks
using slightly modified versions of these programs). In any case they
might give you some clues if you want to write your own programs...
