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.

HP-format floppies.
LIF? They're not DOS compatible.
?A HP 1630G logic analyzer with 9121 GPIB dual floppy drive, and a HP
?80000 data generator. For both machines I have old floppies containing
?critical utilities (including a bunch of disassembly utilities for
?early processors) that I really want to back up on PC and put online.
Now that is as easy as it can be. There's lif_utils from Tony Duell
(http://www.hpcc.org/datafile/hpil/lif_utils.html), or the HP LIF
Utilities (http://www.hpmuseum.net/display_item.php?sw=56) for MS-DOS,
of even the LIF tools in HP-UX (e.g. lifls, lifcp).
But those 3?" HP floppies can be read on any standard PC with 3?"
floppy drive, they are in standard MFM format (with some special
feature to mark bad tracks, they put $FF in the sector headers and
continue with the next track). I've written a tool to
read/write/format a diskette in 9122C format to exchange data with our
HP1000.
