AppleII have a look at AppleSauce to USB connect an Apple Disk][ to a Mac
to flux read the diskettes.
If you?re not Mac interested, maybe someone could do them for you. I would,
but I?m in Sydney , AU.

I had the bug to do something similar.. then I found SuperCard Pro.
It's closed hardware but the USB protocol is fully documented. Because
if that, it's almost a perfect commodity turn-key hardware bridge to raw
flux-level transitions - in or out. It's $100 and in-stock. One could
always build custom hardware, but you'd wind up with something very
similar in hardware and protocol design. What's your time worth?
The heavy lift is always in software. There is an open-source Amiga
disk image utility package that has turned into something more
flux-level generic called Keirf Utilities. And the built-in software is
also descent. But since the USB protocol is documented, the hardware
capabilities can be extended by anyone.

Has anyone used a DiscFerret, to actually extract files from say, Apple II
disks
and HP LIF disks?
The website- https://discferret.com/wiki/DiscFerret
It seemms like the project is dead since 2013, was only ever for Linux,
and never included software
that understands various old floppy formats. Is that right?
My neads (using DOS, WinXP or Win7) are:
* At the moment I'm attempting to restore my old, heavily modified Apple
II to working condition,
and then archive all my old Apple II files on floppies to PC. Part of a
project to document a
bunch of projects I did in my 20s, 1970s t0 1980s.
The intro article is here:
http://everist.org/NobLog/20181001_missing_wave.htm
Another article is in progress, about the restoration and doco of all
the mods I did on my Apple II.
After it's working and old files extracted, then an article about my
hacking Apple DOS 3.2 to
get higher data density. The old thermal printer listings are faded to
illegibility, so I'm
really hoping the floppies are still readable.
* Also I have some old HP equipment that uses 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.
There's sentimental and historical interest with both, and practical need
with the HP gear.
But, I have little experience with data recovery from old floppies. Long
ago I did have a PC ISA
bus card for extracting bit transition images from floppies, but I can't
find it.
Just now starting to look for what's available. Hoping for something that
just works, as I have
way too many projects already.
I do have boxes of old drives, 8" 5.25" and 3.5", most densities.
What other all-formats floppy R/W and data recovery tools do people here
know of?
Comments of their functionality?
