6. Press "Start" to read the program from the paper tape into the computer.
7. Press "Start" again to execute the program.
8. Go to the "teleprinter" tab to view the output of the program.

Learn how to program the machine

Very cool sites to learn about the Z22 computer and how to program it are:

• R. Kirchner's great Z22 documents collection at the computer museum of the Department of Computer Science of the Technical University Kaiserslautern.
• Wolfgang Pavel's great Z22 pages with his cool simulator wirtten in PHP.

Have fun!
