Classic Article Repubs
We hope to republish one or more articles from the Golden Era of the Model T every month:
- ROM Addresses: Getting BASIC to do What You Want
- Format Your Words With This TEXT Aid
- TextStar
- A Simple Self-Charger for the Model 100
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 and Storage
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.
