Naw, no need to worry unless the board gets hot enough to melt solder :>

The amplifone raster monitor is different than the Disco monitor..
Personally I like the Disco monitor, it has a nice tube. The
Amplifone raster monitors look similar to the vector amplifones in that
there is no chassis, the board is mounted to the side of the cabinet.
I,Robot didnt ship with the amplifone, but Firefox did so your I,Robot
may have the Amplifone mount still in place.

Yeah I had all this noted on my page.. all I,Robot owners who use their
game often and run the Atari switcher should run extra leads from
the test points on the boards to the PS. The connector gets pretty warm
otherwise. If the edge connector is dirty the PS will try to dump up to 6
volts on the boards, and then shut down.

Well the HE sticks basically have the same output as an analog stick, so
its probably easily do-able.
