A LeapFrog Didj
History edit
Launch edit
The system was announced on February 5th, 2008.[1] The Didj was marketed more as a gaming device with educational value, rather then an educational device with entertainment value.[2]
The Didj was launched in mid 2008.[2] The system cost $89.99 at launch with games costing $29.99.[1][3]
By February 2010 the system was being sold for as little as $25, gaining the interest of Linux enthusiasts looking for cheap portable computers.[4] By the middle of 2010 the device was discontinued.[5]
Legacy edit
As the system was popular with Linux enthusiasts, a surprising number of mods were developed for it. Such mods included adding MicroSD card capabilities or doubling the RAM to a capacity of 64 megabytes.[6]
Technology edit
The Didj was built on the Leapfrog Pollux Platform.[5] The Didj uses the same CPU as the GP2X at a lower clock speed, with software being relatively portable between the two.[5][7] This processor used a 32-bit ARM9 architecture.[1][4] Different sources list the processor clock speed at either 300 megahertz or 393 megahertz.[1][4] The system had 32 megabytes of RAM, with different sources listing either "DDRI" or "SDRAM".[8][4] The system graphics supported basic 3D with OpenGL ES 1.1 support.[4]
The system had 256 megabytes of internal storage, and cartridge media held 64 megabytes.[4]
The system used Brio Firmware.[4]
The Didj has a 3.2" screen with a resolution of 320 by 240 pixels.[4] The screen can output 16.7 million colors.[4] The system has unused composite out hardware, which can be enabled with modding.[9]
The system was powered by 4 AA batteries, with an optional $35 rechargeable NIMH battery pack available.[5][10][2] 35,000 early rechargeable battery packs sold between October 2008 were defective, and recalled on October 23rd, 2008 as they could burn the user, with one incident of a burnt hand reported.[10]
Games edit
Games could be enhanced with a custom vocabulary.[11]
