ASCII Corp has fitted the thumb keyboard designed by Fujitsu to facilitate Japanese language word processing, to the top-selling NEC PC9800: it has also developed a word processing package called Oya-yubi-kun or little thumb, for use with it: ASCII took a licence from Fujitsu for the thumb shift key-board, and will also adapt to other micros and software, such as Fujitsu’s OA-Shift 98.
