-        <p>This demonstration model was build in 1973, when personal computers were not
-           invented for a long time yet. Engineers had to be trained to understand
-           computer architectures. Therefore, this big education model was constructed.
-           It is a giant implementation of a typical register machine where 126 lamps
-           display all registers, control, ALU and RAM, including the data flow.
-           Featuring a mutable clock pulse and only 4 bit word with, elementary opcodes
-           could be reproduced in a very illustrative way. The device can be toggled to
-           process one instruction or one cycle a time.
-        <br>On the left side, the computer program could be directly "written" by plugging
-           cartidges labeled with assembly instruction mnemonics or numerical values
-           (immediate operands). On this cartiges the user could directly read the binary
-           value of the machine instruction which will be the content of the corresponding
-           random access field. As you might guess, the computer cannot change the program
-           memory without user interaction, so this model actually implements an Harvard
-           architecture, even though the (german) labels on the frontend suggest something
-           different.
-        <br>The picture above shows a currently running program that adds memory cells. It
-           shows that computer word lengths do not limit the length of proccessable
-           numbers.
-        <br>It is a wonderful device that can even be used today to understand the elementary
-           workflow of modern high end desktop CPUs.
