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, with many peripherals designed for the PC-8801 (such as monitors) being compatible with both machines. Built into ROM is N88-BASIC (86), which derives from the PC-8801's N88-BASIC; the two are very similar, and though the languages are not completely interchangable, often only minor changes were required to make a PC-8801 BASIC program run on a PC-9801.

The PC-9801 was significantly more expensive than the PC-8801 at launch; as well as taking into account for the computer itself, customers were expected to purchase an external PC-9881 8-inch disk drive in order to interface with the machine. Likewise while the default PC-9801 can handle some types of kanji characters, if the user wanted to make full use of word processing software, a PC-9801-01 expansion board would need to be purchased for JIS kanji level 1. Were a printer required as well, the combined cost would reportedly total nearly ¥1,000,0001,000,000.

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".

The PC-9801 and all subsequent models support four screen modes: 640×200 with 2 colors and 6 pages, 640×200 with 8 colors and 2 pages, 640×400 with 2 colors and 3 pages, and 640×400 with 8 colors and 1 pages.
