In fact, it’s been around for nearly two decades and its sole purpose is to emulate DOS in an x86 environment. Just to be clear, this application is not new. Along the way, I discovered a nifty little app that I had never heard of until this week. Somewhere along the way, I decided to fiddle with MS-DOS. I’m back at it! I spent the better part of yesterday morning tinkering with virtual machines and the Linux container on my Chromebook to see was sort of shenanigans I could get myself into.
