This mod will increase the overall speed of your asteroids game. You will need some 30 gauge wire and a switch. 1. Clip and lift pin 4 of C5 (74LS161) 2. Wire switch as follows: * Common to lifted pin 4 * Normally closed to pad where pin 4 used to be connected * normally open to pull up resistor next to C5 NOTE: 1. Be sure you wire the end of the pull-up resistor *not* tied to +5V. 2. Clipping any other pins besides pin 4 may have adverse effects on Audio, Video, and/or coin discrimination. --
