These latter programs may or may not evolve into a real (playable) game, as often the memory of the SX52 processor is too restricted to support them. Some people also write non-game video demos to show off the video display possibilities of the system. The SX52 has been made obsolete by Parallax, the company that now packages the SX-series of micro controller dies, made by Ubicom, because they did not have a package with 52 pins. However, according to the people at XGameStation, there are enough SX52 chips available for all their future needs. On July 31, 2009, Parallax announced that the whole line of SX microcontrollers will be discontinued. The Pico Edition is a simplified version of the Micro Edition in a build-it-yourself kit. The Pico Edition is based around the SX28 microcontroller, which, like the SX52, is a high-speed PIC microcontroller running at 80 MHz for a total of 80 MIPS, though it has less RAM and Flash capacity. Like the Micro Edition, the color television video signal is generated in software on the microcontroller. However, unlike the Micro Edition, the audio signal is also generated directly by the microcontroller and not by an external chip. For input, the system simply reads pushbuttons connected to its input pins. Programming is done in assembly language or in a custom written XGS Basic, on a PC and then transferred to the console. The Pico comes in several different kit forms: the 1.0 kit which comes with a breadboard, a CD with assembly instructions and selected chapters of the same ebook as the Micro Edition and the same extras, the SX28, and the discrete components of the system; and the 2.0 kit, which consists of the 1.0 kit and a PCB (which is also available as an add-on separately); and the Game Console Starter Kit, which includes the 2.0 kit, a hard copy of "The Black Art of Video Game Console Design", and a soldering iron and solder. Released on December 26, 2008, the XGS AVR 8-Bit and XGS PIC 16-Bit development systems are embedded system development kits, meant to be very competitive entry/midrange development kits for their respective microcontrollers. The systems were designed together and so share much of the same design other than the main processor. The video signal is generated in software like the XGS Micro and Pico Editions; however, there is color helper hardware to generate the colorburst part of the video signal.
