Disk images

The disk images are provided basically in the following formats:
  1. The rdm20 and wrm20 programs: decompress the file with bzip2 and then use the Dwight Elvey's programs rdm20.com and wrm20.com described in the Transferring files section of this site.
  2. ImageDisk, a program written by Dave Dunfield, which can be found here.
  3. Teledisk, an old disk copying program, which is no longer sold (have a peek here...)
If you own a software which is not included in this list, please consider to contact us.
If you want to take screenshots, comment programs or write tutorials, contact us also!
