The PC-9801 is a computer released by NEC in 1982, and the first computer in the PC-9800 series.

Hardware

The PC-9801 was envisioned as a high-end business machine by NEC, being built around a 16-bit µPD8086 processor (NEC's version of Intel's 8086) and two µPD7220 graphics chips, developed by NEC to efficiently display the kanji character set (at a high enough resolution to read). In this original setup, one is used for graphics, and the other for text.

This PC-9801 shares much in common with the original PC-8801, released a year prior, expecting that the user purchase external disk drives in order to interface with the machine. Also built into ROM is N88-BASIC (86), which derives from the PC-8801's N88-BASIC, with many commands shared between the two (though some differences mean the two languages are not completely interchangable).

While not strictly designed for gaming, the PC-9801's popularity in business inevitably led to video games being produced for the system (not dissimilar to the IBM PC in the West). The PC-9801 has higher resolution graphics than most of its contemporaries, but is limited to 8 colours. Much like the PC-8801, sound hardware is limited to a simple "beeper".
