Spectrum Betadisk / TR-DOS Disk Utilities

Please note this content is from the original WoS site, and may no longer be relevant. If you have any queries, please contact us.

The Russian Spectrum models use the TR-DOS disk operating system. As more and more emulators support this, it is time to convert your disks to emulator files.
Lots of utilities to work with Betadisk/TR-DOS images are available on the net, and this is just a small selection of them.
Erik Kunze wrote some of these (EMPTYTRD, HOB2TRD and TRD2HOB) for the Unix environment and they are included in the XZX distribution.
