About OneZero OneZero began as a variation for my bit-mapped font in 1993. It was like an uncompleted "sketch". Late 1995, I redesigned this font for my personal promotional poster. Then, the new concept for this font came to me, namely OneZero. The image of conbination of on/off and positive/negative. As soon as I began to add variations for OneZero, I faced the problem that there was not enough memory to draw letterform with the increased circle dot patterns. In 1998, OneZero has completed with Japanese Kana complements, having more memory chips. OneZero is designed by Yamaoka Yasuhiro 1993-1998.
