In February 1999, the μClinux project's Linux kernel was ported to two ColdFire processors (MCF5206 and MCF5307). In 2006, the Debian project was looking into making its m68k port compatible with the ColdFires, as there are ColdFire models that can be clocked as high as 300 MHz. This is much faster than the 68060, which can officially reach 75 MHz and can be overclocked to 110 MHz. Stallion Technologies ePipe, Secure Computing SnapGear security appliances, and Arcturus Networks's System on Module products are based on ColdFire processors. There are ColdFire Linux-based single-board computers (SBC) with Ethernet and CompactFlash as small as 23×55 mm or 45×45 mm or based on CompactFlash (37×43 mm) itself. ColdFire based products have even been deployed to the International Space Station as an electronic nose project.
