The CP/M operating system, popular in 1970-s, standardized computing for business and was a precursor to MS-DOS. I like to play with retro computers, Commodore 128 being my favorite 8-bit system. It can run CP/M and since text based user interface is still my favorite, I enjoy working with this system. One application lacking on the system was a screen saver to display random content on the screen to prevent CRT burnout. I also wanted to have an optional screen lock function, where user would provide a passphrase to unlock the screen. Some applications are equipped with their own screen blanking function, e.g.: VDE editor with control key combination can blank the screen until restored with a key press. However I wanted something like that to be available from the system prompt, as a standalone application. Enter SCRSAV project, written in Aztec C version 1.05. I will soon include compiled binary for those that don't have Aztec C compiler or don't want to mess with it.
Enjoy!
