These are the days when the majority of tournaments were semi auto. You'd tap a code into the gun via the power and eye buttons (like, eye, power, power, eye, power, power) which would activate uncapped ramping. If a ref or other player wanted to try you simply knocked any button and it went back to semi. Although there were board shenanigans for a while it's the product that ultimately helped kill semi automatic and led to ramping being normal
The guys that made it were talented and knew their stuff. Later they went on to make more normal boards, they also rebranded their company to reflect their new non cheaty ways. The name of that new company? Virtue.
