Notes on compatible accessories:

• The only gamepad input that is compatible with this model is SR modified Gravis Destroyer (or SR provided parallel port button box)

  • This is because the host PC directly probes it for input when using EyeTrack

Accessories

Gravis Destroyer

Buttons do not work in Test mode in EyeTrack, only in Run mode!

Gravis Destroyer (out of production) supplied by SR Research

• Only detectable by host PC when attached before booting up either computer

• Buttons are misaligned for EyeTrack code

EyeTrack code listed as:	Corresponding Gravis Destroyer button:
[1] blue	blue
[2] red	green
[3] green	yellow
[4] yellow	red
[5] purple	purple

• It may be the case that the blue/red/green/yellow buttons get realigned every time the Gravis Destroyer is unplugged/replugged into the host PC.

  • This can be fixed by including all four as possible ways to indicate a “No” answer.

• Purple seems to be static; this can be used to indicate a “Yes” answer.

• This means output.script has to be manually altered to get all the buttons and intro text to be accurate.

Make sure to “Validate” the experiment before running!
