WTB: kryoflux and compatible drive

[tblake05]

Hello all,

just acquired a pile of old 5 1/4 floppy disks. Was told they could contain some old fortran/cobol programs as well as trs-80 programs and typed in BASIC games from pc world magazines some 40+ years ago. I’m intrigued, but I want a way to read the disks RAW data and dissect it from there. Kryoflux seems the ticket. That said....

anyone have a kryoflux available they aren’t using anymore. Also in search of the most compatible 5 1/4 drive to the kryoflux. Has to be able to read both sides. And SD, DD, and HD. Any recommendations I can source off eBay?

This is not one of my pressing projects, but in the future when I extract the data, anyone want to help me go through the files for anything interesting?

You have other options available that are less expensive such as Supercard Pro by Jim Drew, GreaseWeazle by Keir Frasier, and
Fluxengine by David Given. The Kryoflux is the most expensive option, and will do the job.

Kryoflux:
You will likely be making files for each track of every floppy, and those can be streamed back to make multiple copies of the
original floppy. So, there will probably be a mix of 40 Track (48TPI) and 80 Track (96 TPI) files for all the floppy's you process.
The best option would be a 360K and 1.2M Floppy drive available so you have both 48 & 96 TPI Drives for the reads. The
Kryoflux will give you information on the reads as you process the floppy if you use the command line switch to show that
information. The Streamed files (.RAW) are not the RAW type you are referencing, as you are wanting an actual Sector
Dump (RAW Data). You should end up with an individual sub-directory for each processed floppy's Streamed files. You will
have to make an intermediate conversion to .IPF, then create a .IMD file to allow creating the .RAW image.

There is a Kryoflux Guide at https://forum.kryoflux.com/viewtopic.php?f=3&t=853

The Supercard Pro, GreaseWeazle, and Fluxengine should give similar results at a lower cost.

I prefer TEAC Floppy Drives for 5.25" floppy's, but a Tandon TM-100-2A will also do the job for a 48TPI Floppy,
and a TM-100-4 will handle 96 TPI floppy's.


chuck(G) recommends a thin film of cyclomethicone for floppy lubricant.

The hxc software will read the kryoflux raw files and allow you to export a sector image, will this not work for cp/m or trs-80 floppies?

The HxC Softare sure will, and it will run on Windows & Linux, but I didn't mention it on purpose because that is opening up another can of worms
to mix with the already open three cans of worms.
