&gt; Built from simple logic chips, it runs at a blistering 4MHz, has 32kb of RAM<p>I know that the author was being sarcastic, but really, 4MHz with 32kb of RAM is like state of the art 80&#x27;s technology. The fact that we are even able to get to this point with protoboards and discrete off-the-shelf logic chips is impressive.<p>I mean, I learned how to program back in 1988 in a computer not much more powerful than that.
