I opened up one of my atari 2600 games, and instead of a regular : chip inside, there was this small plastic glob where the ROM chip : should be!!!! what is this? It's called "Chip on Board". The chip (or die) is glued or soldered right to the circuit board, wire bonded to the circuit and protected with a glob of epoxy. Saves the expense of bonding the die to the lead frame, moulding the epoxy package around it, attaching the packaged part to the board, and soldering it. Sure it might break sooner, and there's no way in hell you can repair it, but with consumer electronics, you get what you pay for. Mark Zenier markz@ssc.wa.com
