PD Pack for Mac.
The origin of DVD-RAM is in PD (phase-drive, or phase change) technology. The original PD system has become a legacy, but out of the experience gained from PD technology, DVD-RAM technology was born. DVD-RAM offers the best solution for storage going into the new millennium.
From the museum of software, ver 1.0 of PD Pack for Mac, the forerunner of DVD-RAM TuneUp, all from Software Architects. Since FLAAR. has four PD units (and hundreds of PD disks) we still had the original software in our office.
