Remarkably, the Atari 8-bit is in a bit of a renaissance now, with many fascinating projects being developed both commercially and as open source. There are products to upgrade the memory to 1MB (significantly more than stock), upgrade the CPU to 20MHz (nearly 20x its original clock speed), and output modern digital video directly. One of the most impressive projects to hit the Atari 8-bit scene recently is FujiNet.
