TPDD client

A "TPDD client", also usually called a DOS(note), is software that runs on the portable and can read and write files on a Tandy Portable Disk Drive or Tandy Portable Disk Drive 2, or any of their rebadged versions like Brother FB-100 and Purple Computing disk drive, or any "TPDD server", software which runs on a pc and emulates a TPDD.

To use a real TPDD or TPDD2, you need the special cable that came with the drive, or a new cable that has the same electronics inside.
