Nec PC-8001 mkII SR

Historia

A games-oriented revision of the PC-8001mkII with significantly better graphics and sound, making its debut in January 1985 for 108,000 yen. The mkIISR increased the frame-buffer memory from 16KB to 48KB, allowing for 640×200-pixel graphics or 320×200-pixel double-buffered graphics modes. Additionally, the primitive PC speaker was replaced by an FM synthesis audio system. Its internal BASIC was also updated to allow usage of this new hardware, as well as providing mkII and PC-8001 compatibility modes (although a significant proportion of older software would not run properly under these modes). Other changes included the change of one general-purpose expansion slot to a Kanji character ROM expansion slot, a PC-8800 series keyboard connector, and an Atari-style joystick connector.
