NEC µPD7220
The High-Performance Graphics Display Controller 7220 (commonly μPD7220 or NEC 7220) is a video display processor capable of drawing lines, circles, arcs, and character graphics to a bit-mapped display. It was developed by NEC in order to support the Kanji character set efficiently, which explains why the APC computer line had such superior graphics compared to competing models. The chip was also used in later computers, such as NEC's PC-9801 and the NEC APC II and APC III computers, the NEC N5200 intelligent kanji terminal, the optional graphics module for the DEC Rainbow, the NCR Decision Mate V, the Tulip System-1, and the Epson QX-10.
