I need DOS 6.22

I work in one of the older casinos in Vegas, and one key system still runs on DOS 6.22…Welp, I need to do a little testing on a different DOS machine, so I don’t screw up the critical machine…Problem? I don’t have another DOS machine, nor do i have a copy of it…Question – Where can I download a copy of DOS 6.22?

I don’t feel like searching the web to find one, so I figure I’ll help my brethren by handing over some incredibly valuable Tech Points.
