quarter of 2006. However, company turbulences (see Company History below) prevented the K9 from being sold until early 2009 by Inaura, Inc. Promotional literature shows the form factor to be the same as the intermediate iD3 prototype a very thin chrome model resembling an iPod Nano, but all black with a rubberized exterior. Before Realm Systems shut down, there were working prototypes of the K9, the hardware design seemed to be finished, and the software was functional. In terms of hardware, it differed from the Original BlackDog in these aspects: 128 MB RAM 1GB Flash NAND Memory 60 pin Hiroshi connector replaces MMC slot (intended for a USB connection cable, as well as custom cables to support additional peripherals) OLED display replaces indicator LED of first version (1.1 inch display, 96x64 resolution, 4 bit grayscale Black and White) Dimensions, H×W×L: iD3 The iD3 was a variant of the K9, using the same hardware specifications, intended for corporate use with a matching management router/server identified as the iD1200. It was announced as being part of the iDentity product series and was, for instance, showcased on the Embedded Systems Conference in San Jose, CA (April 3–7, 2006). The final Realm Systems iD3 form factor resembled a small Nokia cellphone. Software The software was originally based on Debian until 2008. The project switched to using Olmec Linux. Debian Linux (pre-2008) When plugged into a USB port of a Windows XP machine, the BlackDog initially presented itself to the host as a virtual CD-ROM drive. Via an autorun application the BlackDog then automatically launched the X Window system for Windows Xming and a software NAT router. Once those applications were running, the virtual USB CD-ROM drive disconnected, and the USB presented itself as a virtual Ethernet adapter, enabling network access. Without requiring any installations or user interactions, the user could access the contained applications and data from any Windows computer. With further configuration steps, it was possible to also run the BlackDog on Linux and Mac computers. A short Engadget review stated that "it runs Firefox fine, and should be great for taking your own browser, e-mail, and chat clients for use wherever \[you are\], though that will probably be about all this little 400MHz guy can handle." The first software version was based on Debian Sid running a 2.6.10 Kernel. It contained some sample default applications such as xterm, XBlast, and XGalaga and
