+ * Author: Josh Holtrop
+ * Date: 2009-05-03
+ * 
+ * This module provides a C++ object-oriented interface to a
+ * Noritake itron Vacuum Fluorescent Display model CU20025ECPB-W1J
+ * that my friend Mike Zwagerman let me borrow.
+ *
+ * It is connected to my PC's parallel port as follows:
+ * CN1 Pin  Parallel Port Pin
+ * Gnd   1  18  Ground
+ * RS    4  2   Data0
+ * R/|W| 5  3   Data1
+ * E     6  4   Data2
+ * DB4  11  5   Data3
+ * DB5  12  6   Data4
+ * DB6  13  7   Data5
+ * DB7  14  8   Data6
+ *
+ * Additionally, CN1 pin 1 (ground) is connected to an independent 5 volt
+ * power supply's ground, and CN1 pin 2 (Vcc) is connected to the
+ * independent power supply's +5V line.
