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.
