--- layout: page title: Challenger 1P Applications permalink: /apps/c1p/ --- Challenger 1P Applications --- See [GitHub](https://github.com/jeffpar/pcjs/tree/master/apps/c1p) for program listings and configuration files. The C1P serial port has no configurable hardware features. However, there is a "demo" property that can be set, causing the machine to load some built-in demonstration code via the serial port when it starts up. The purpose of the configuration files is to create UI controls that allow you to choose from a set of programs (eg, BASIC programs, 6502 machine code files) and send them to the C1P through the serial port.
