Application Software Component 002 from Timex’s Application Development Library. It’s a machine-code module that gives TS2068 programs 80 columns of text. It switches the computer into its 64-column video mode, opening the second display file to do it, and draws its own characters six dots wide.
The first 17 pages are the typed documentation. They cover each service: set mode, clear, set cursor, set colors, set inverse and over, write a character or string, scroll, and read back characters, colors and the cursor. They also explain how to call the module from BASIC and include notes on memory use, margins and automatic scrolling.
