Tools like the Kryoflux record raw flux transitions, so they don't care whether the modulation is FM, MFM, GCR, etc. But they do need to be used with a drive whose track positions and head geometry are compatible with reading and/or writing the floppy disk in question. Whether a TPDD disk can be imaged and/or created with something like Kryoflux will depend on the track positions and track width used by the TPDD's mechanism. Is there any documentation available about the TPDD's physical track positions on the disk? If they happen to line up with track positions of common 40-track or 80-track drives, then there's a chance. -- Mark J.
