Original models of the NEC PC-8001 (or sometimes the NEC PC-8000) was also sold in some European countries like in the UK, France, Spain, Italy and the Netherlands and in Australia and New Zealand as well.
The first member of the PC-8000 series, the PC-8001 was first introduced on May 9, 1979, and went on sale September 1979 for ¥168,000. Its design combined the keyboard and the mainboard into a single unit. At a time when most micro-computers were sold as "semi-kits" requiring end user assembly, the fully assembled PC-8001 was a rarity in the market. Peripherals included a printer, a cassette tape storage unit, and a CRT interface. Although it is often believed to be the first domestically produced personal computer for the Japanese market, in reality it was preceded by the Hitachi Basic Master.
The PC-8001A was released in the United States in August 1981, and was priced at US$1,295 (32 KB of RAM). It was reduced electromagnetic interference to comply with FCC regulations. Katakana glyphs in the character ROM were replaced with greek alphabets.

In Japan, Nippon Electric's Microcomputer Sales section in the Electronic Device Sales division released the TK-80 in 1976, a single-board computer kit, and it became popular among hobbyists. American personal computers were expensive for personal use (Initial list price of the Apple II was 358,000 yen, and the TRS-80 was 248,000 yen). In addition, computer manufacturers had not developed personal computers because they assumed microprocessors were not suitable for computing as lack of performance and reliability. In 1978, Hitachi Basic Master and Sharp MZ-80K, both were not developed by computers divisions, were released as a personal computer targeted for hobbyists, but not for business.
In summer of 1978, they started the development of the PC-8001, codenamed "PCX-1". The development team consisted of 10 engineers including the section manager of Kazuya Watanabe (渡辺 和也) and the chief designer of Tomio Gotō (後藤 富雄). They had already planned a shell-covered version of the TK-80BS as a personal computer. It was released as the COMPO BS/80, but it was failed in the market due to its poor built-in BASIC and slow clock speed. The PC-8001 was aimed to design as a high-performance and inexpensive computer for personal use.
The team had already been developing a BASIC interpreter, but Watanabe decided to adopt Microsoft BASIC because it was widely used in North America market. At that time, Microsoft and ASCII (Microsoft dealer in Japan) intended to expand OEM business in Japan, so the N-BASIC was provided for NEC with very low licence fee.
The system unit, displays and storages were developed by Nippon Electric, and manufactured by New Nippon Electric (NEC Home Electroncs) from January 1980. Printers were provided from Tokyo Electric (Toshiba TEC) because NEC had only developed expensive printers for mainframes.
Success in JapanEdit
The PC-8001 was introduced on May 9, 1979, and its prototype was presented to the public at the Microcomputer Show '79 (マイクロコンピュータショウ'79) held in May 16-19 at Tokyo Ryūtsū Center. Soon after the exposition, NEC got thousands of orders. It took a half of year to ship about 10,000 of back orders after the shipment began on September 20, 1979. In 1981, the PC-8001 dominated 40% of the Japanese personal computer market. 250,000 units were shipped until the production stopped in January 1983. NEC succeeded in expanding their personal computer chain in Japan. The chain owned 7 stores in 1979, 15 stores in 1980, more than 100 stores in 1981, and reached 200 stores in 1983.
The PC-8001 sold well in the educational market because NEC advertised that the PC-8001 adopted the industrial standard of Microsoft's BASIC. Kanagawa Prefectural Chigasaki Nishihama High School was the first futsu-ka school (upper secondary schools focus on a common course) who purchased 17 units of PC-8001 and started teaching programming with an elective subject in 1981. In April 1982, NHK Educational TV started the television program "Interest course 'Introduction to Microcomputers' (趣味講座「マイコン入門」)" using the PC-8001. Its textbook "Introduction to Microcomputers - the first half of 1982 (マイコン入門 昭和57年度 前期)" sold 700,000 copies.
A higher-performance, more graphically capable revision of the PC-8001, the Mark II debuted in March 1983 for a price of 123,000 yen.
While its most obvious improvement was in its graphical capabilities, the Mark II also included an internal 5.25" floppy disk interface as well as two internal expansion slots, doing away with the need for an "expansion box" to permit upgrades. The internal BASIC was changed as well, from the 24KB N-BASIC to a 32KB "N80-BASIC" that added new conditional statements as well as graphics commands.
While the price of the PC-8001mkII was comparable with other 8-bit computer offerings at the time, its graphics were notably worse than its competitors (most likely an attempt on NEC's part to avoid competing with their own, higher-powered PC-8800 series). This led to a relative dearth of software produced for it, particularly games.
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.
Morichika Sawanobori (沢登 盛親), the division manager of NEC's Electronic Device Sales division, recalled why the PC-8001 became a long seller that "The biggest factor is the price setting of 168,000 yen. The major opinion insisted 220,000 to 230,000 yen was appropriate for value of the product, but Kazuya Watanabe never withdrew 168,000 yen. After all, Watanabe's proposal was accepted by the executive director Ouchi's decision, but his stubbornness was admirable."
Although handicapped by the lack of English documentation, BYTE's American reviewers concluded in January 1981 after evaluating a unit purchased in Japan that "the PC-8001 appears to be an attractive, well-planned, and well-made personal computer ... Most people who have seen our PC-8001 feel that, if it were sold in our country, it would provide strong competition for any of the color-based home computers currently being sold".
