Disk Power and Disk Power II by Hugu Ferreyra / Ultrasoft Innovations
Disk Power was available for at least the Tandy Model 100/102 & 200, and Kyotronic KC-85 machines.
Versions for NEC PC-8201a and Olivetti M10 are likely but unknown.
The only documentation available about Disk Power is there are many references throughout the M100SIG Archive.
Few copies are available today, as it was designed to be impossible for the user to copy.
Both the original distribution disk and the cassette were required to install the software, and there was no way to copy the disk using any software available at the time. There is no technical reason to require both a cassette and a disk to install a single program. The scheme merely functioned as a means of copy protection because a cassette could be copied but the disk was specially crafted to prevent copying.
Today there is a tpdd utility that can read & write TPDD1 and TPDD2 disks more completely than what was previously available. If any physical copies of Disk Power do turn up now, it will be possible to archive and redistribute them. This has been done for the KC-85 version.
