  • It's not surprising when you can't find any information about a computer from a small unknown company. This is different. The computer computer in this video was sold by Leading Edge, a rather prolific and popular PC clone maker. It honestly baffles my mind that there appears to be zero information about the existence of this machine on the internet. That changes now!
