Hi, I am trying to run a basic assembled .asm file on the handy-board without IC. Since the board doesn't have a reset button, do I use the power on reset (turning board off/on) vector location of $FFFF:$FFFF to indicate the start of my code? -Luke (28 years ago, 18-Feb-97, to lugnet.robotics.handyboard)
