Caldera released Digital Research's DR DOS 7.01 as FOSS. It then changed its mind and made v7.092 closed-source again, but 7.01 remains FOSS and turned into OpenDOS, AKA DR OpenDOS and Open DR DOS. And, for what it's worth, DR DOS has multitasking, and I've tried it, and it works. > There were versions of ms dos that escaped into the wild, but it wasn't > a sanctioned release from microsoft.
