The system selects between the 32 banks with the position of five toggleswitches. There are 
32 combinations of these five switches being either up or down. Four of the switches are in 
a horizontal row. The fifth is below them, and is associated with a pushbutton switch which 
reverses its function. The purpose of the pushbutton switch is to provide a convenient and 
instantaneous means of switching banks. 
The switches are not labelled. There is no particular numbering system for the banks. Using 
a binary number system, the 32 banks could be numbered as follows. 
 '
▼
' and '
▲
' refer to down and up states of the five toggleswitches. We interpret these states 
as binary bits 0 and 1 respectively. For instance the photograph above shows the 
toggleswitches set for bank 1.
