In this first teardown we will take a look under the hood of a Defzone 300sg firewall. These firewalls have been sold around the year 2007 and are not supported anymore. Moreover, there is no information in the internet on this device and its manufacturer. Time to take a closer look at the hardware used in these devices! Case The case is a simple looking 19 inch 1U rack mount case.
This small side project started by buying a Diamond Lady pinball machine with a defective display. We had to find out why the display wasn’t working.
