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.

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
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.
