ROMDOS continues to be designed into many applications. It is well known to programmers, and it's small, fast, reliable, and inexpensive. Regardless of whether you have a new design or an existing design, EMAC offers ROM DOS version 6.22. EMAC will load ROMDOS onto a Flash Disk at no charge with the purchase of an SBC, RAM, and Flash Disk with ROMDOS License. (While Microsoft DOS 6.22 Licenses are EOL and no longer sold, we can still offer ROM DOS, which is compadible.)
