These pages are devoted to the Model T:

Tandy Disk Drive and Emulators

TPDD emulators, in concert with a compatible disk clients like TS-DOS, TEENY, POWR-DOS, FLOPPY.CO, the Booster Pak, or the WP-2 built-in Diskette client are the most "advanced" way to accurately and quickly transfer all file types including binary files to and from your Model T laptop. There are different options for the server side on modern operating systems and devices:

Servers

LaddieCon is a TPDD emulator for Windows written in C#.Net.

DLPilot is a TPDD emulator for PalmOS devices.

DLPlus is a TPDD emulator for Linux, BSD, and MacOSX.

Clients

TEENY is a very small RAM-based TPDD client

Real TPDD and TPDD-2: Differences

  • They are different in that the TPDD 1 is a 100K disk format, and the TPDD 2

uses a 200 K format.

  • The TPDD 1 has dip switches that must be manipulated during boot and the

TPDD 2 doesn't have this requirement.

  • The TPDD 1 can only read a 100 k disk where the TPDD 2 can use either one.
  • They both have the same battery and PS requirements as all of the Model T's.
  • They use the same cable.
  • They both are usable on all 3 of the Model T's.
  • They are similar in that they only need a single sided disk.
  • Yes the boot disk for each which is specific to the drive must be loaded

into the computer before use but there are alternative OS's available which have various load requirements.

  • They have different protocols for raw sector access mode. The file access mode is very similar

Simple Text File Transfer (No Client)

You can use any "terminal program" to transfer text files to and from your Model T laptop. Here are some tutorials:

Text File Transfer using Hyperterminal

Text File Transfer to Mac using Z-Term
