Smallfoot was the name of both a rapid application development toolkit and an embedded operating system designed and released by Caldera Systems/Caldera International/The SCO Group in both UnixWare and Linux formats.
A deal was signed in January 2003 for Smallfoot to work on Beetle point-of-sale terminals from Wincor Nixdorf.
[4] But given the SCO–Linux disputes that were underway a couple of months later, the Smallfoot Toolkit development switched to a Unix-based OS in May 2003.
[5] The further development, including a GUI, was shelved until the sales of the command-line version of the toolkit would pick up and provide a revenue stream.
[7] The project became an early success story in terms of stores taking a chance on a Linux-based solution.
