Lesson 11: Advanced Topics
From the original article in Radio-Electronics
by Jonathan A. Titus
These experiments build upon the information presented in the main article . If you are in doubt about a point that has been discussed, go back and review it before starting the experiments. These experiments use the minimum memory configuration of 256 eight-bit words. More memory may be used , but it is not necessary for these experiments. A keyboard or an output device such as the TV typewriter is not necessary for these experiments. If an ASCII keyboard is connected to the minicomputer, connect it to input port 0.

As it turns out, such a system is not trivial.
