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.

To use a TPDD server aka emulator, you need a normal Model_T_Serial_Cable.

Here are some of the major DOS's for Model T computers:

• floppy - The official DOS that came with the TPDD
• flopy2 - The official DOS that came with the TPDD2
• TS-DOS - Commercial DOS from Travelling Software. Now free.
• Tiny - A tiny DOS
• Teeny - An even smaller version of Tiny, and the smallest DOS
• DSKMGR - An early alternative DOS. One of the only things available for Kyotronic KC-85 and Olivetti M-10.
• POWR-DOS / POWR-DISK - An early DOS from Acroatix.
• Disk+ - Commercial DOS option ROM from PCSG.
• Disk Power - Commercial DOS by Hugo Ferreyra.

Note, the term DOS does not mean MS-DOS in this context, but the generic term for any disk operating system.

Here are some TPDD clients that run on other systems:

• TpddTool.py - Python. Runs on anything that has a Python interpreter and the PySerial module.
