Archiving OS65D disks with flux-level analyzers

Post by lowrybt1 » Mon Jul 17, 2017 3:17 am

I’ve been looking at hardware solutions for archiving old disks into image files with the ability to write the images back to fresh disks. There are a couple of solutions that create images by reading disks at the flux level: something called Kryoflux, another called Supercopy Pro. Does anyone know if these can be used effectively to image OS65D disks and write those images back to old media?

Hi,

I have no experience of the Supercard Pro, but the Kryoflux should certainly be able to do it in raw stream mode.

More on the raw stream mode here:

You could write your own OSI disk format decoder, but that would be no easy task.
IMHO, the Kryoflux is complicated beyond belief to use for odd formats (and I have one).
It tries to be all things to all people.

Better to use something designed specifically to read/write OSI disks.
Either a 6821/6850 based device, or something in an FPGA.

Currently looking along these lines for something to go with the C4 FPGA project.
Should be relatively easy to interface with a "real" 5.25"/3.5" disk drive.

From there, the disk images can be saved to a PC via the serial interface.

Cheers,
Leslie
