Classic Article Repubs
We hope to republish one or more articles from the Golden Era of the Model T every month:

One-Liners
This is a collection of Microsoft BASIC programs that
- Do something interesting or useful
- With only a single line of code
One-liners are bite-sized computer programs on a human scale. You are encouraged to type them in manually (by hand) and study their operation.

File-Transfer
We still use Model Ts today, so file transfer to/from desktop and modern laptops is an important issue. There are multiple alternatives, from simple text file transfers using TEXT, TELCOM, or BASIC, up to dedicated file transfer protocol client and servers.

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 popular 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
The TPDD Services implement the "disk drive" end of the TPDD protocol.
Clients
TPDD Clients are software that runs on your Model T laptop. The communicate with a disk drive or other TPDD Service to save and load files.

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:

Fast Binary Transfer
TBACK is a unique approach to file transfer. It allows freeze/thaw of the entire RAM of the laptop, and now fast installation of .CO files to the laptop.
It is a "thin client" solution where the only client is a small program downloaded to the T just for the purpose of the file transfer. All of the "smarts" run on the modern desktop or laptop.
TBACK also targets developers; being able to quickly offload the full RAM of a system for inspection on the desktop, and to quickly change to completely different configurations is a novel feature introduced by TBACK.
