In a world of Gigahertz CPUs and Gigabytes of memory available to programmers, there are things that we seem to have forgotten. Build something using only the bare minimum of functionality, that is provided by your CPUs ISA.

Instead today we create on top of several layers of abstraction and indirection. Don't get me wrong, that is good. Otherwise we would still be living in the digital Stone Age. But from time to time every programmer should look back and admire the ingenuity of those people in the late 70's and 80's and learn from how they achieved so much with so little.

How Pitfall Builds it's World is a well written article by Jack Evoniuk. If you are familiar with 6502 assembly, you will feel at home. If not you will quickly get into it.

Definitely worth your time. Check it out.
