These kits have an internal reference code EB-* with EB-1000 being the first unit developed and EB-2000S being the last known unit made available.


The image on the left is the only known image of the prototype development kits and it was taken from a Sony Dev conference presentation 1. The development kits were used as a build target and connected to the development PC via a PCI interface card so the PC would send down the code to execute and the kit would run it and display the output on a separate screen. Since the hardware was still under heavy development, only a select few studios were trusted enough to get sent one of the Prototype PS2 development kits. Before the retail release of the Playstation 2 hardware developers needed to start development so that the console would have titles on launch.
