Circuits by Nicholas Duchon
The lessons in this instance are circuits from Computer System
Architecture, 3rd edition, by M. Morris Mano.
The applet starts in its own frame and may be hidden - you may need to
use <alt>-<tab> to find the actual applet.
This version uses a custom Lessons menu, derived from the "extras"
parameter:
<applet code="Circuits.class" archive="Circuits.jar"
height="100"width="100">
<param name="extras"
value="http://nova.umuc.edu/~duchon/CIRCUITS/lessons/mano/index.list">
<param name="ccnd" value="Mano Figures">
