One problem you may encounter reading LIF format diskettes on a PC using 
these tools is many LIF diskettes are formatted 256 bytes/sector and 
there is lots of PC diskette controller out there that cannot deal with 
that including all USB diskette drives I am aware of.  I use a Panasonic 
CF-45 laptop that has a built in diskette drive.  HP's LIFUTIL can be 
set up to use HPIB storage such as 9122s via a HPIB adapter card.
