XGS Pico Edition (PE)
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.

Famous quotes containing the word edition:
“I knew a gentleman who was so good a manager of his time that he would not even lose that small portion of it which the calls of nature obliged him to pass in the necessary-house, but gradually went through all the Latin poets in those moments. He bought, for example, a common edition of Horace, of which he tore off gradually a couple of pages, read them first, and then sent them down as a sacrifice to Cloacina: this was so much time fairly gained.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
