PC-98

This is a special computer from Japan.

It was made by a company called NEC. Many people used it for work. It was also used for school.

Writing in Japanese can be hard for computers. This machine could show many Japanese words easily. This helped it become very popular.

It could use floppy disks to save things. Some models used two disks at once. This was very helpful for business work.

Many people in Japan owned one of these. It was a very famous machine.

The PC-98 was a famous line of computers from Japan.

A company called NEC made them from 1982 to 2003. These machines were very popular for business and school.

By 1999, more than 18 million units had been sold.

Writing in Japanese can be tricky for a computer. Japanese uses kanji, which are thousands of complex characters. Many global computers could not show these well. The PC-98 was built to handle these characters easily. This helped it lead the Japanese market. By 1991, it held more than 60% of the market share.

The first model was the PC-9801. It launched in October 1982. It used an 8086 CPU, which is the brain of the computer. It also had a colorful 8-color display. Users could save work on floppy disks. Some models even used two disks at once. This helped people with big business tasks. Later, the PC-9801VM became a top seller. It used a special V30 processor to work even faster.

The PC-98 was a famous family of personal computers from Japan.

A company called NEC made these machines from 1982 until 2003. These computers were very important for the Japanese market. They were used for business, school, and even hobbies.

By 1999, NEC had sold more than 18 million of these units. This helped NEC become a leader in the computer world. Many people used them for many years.

These computers worked in a special way to handle Japanese writing. Writing in Japanese uses kanji, which includes thousands of different characters.

Most global computers could not show these characters easily at the time. The PC-98 had special parts to make this task simple. It used display controllers to manage both text and video graphics.

This allowed the machine to show complex characters clearly. Because of this, the PC-98 became much more useful in Japan.

Developing the PC-98 was a big project for the NEC team. A man named Hamada led the planning for the new machines. He wanted a computer that could work with older NEC models. The team even had to write their own version of a language called BASIC. They worked hard to make sure the new system was reliable. They also gave free prototypes to other companies to help. This helped more people create software for the new computers.

Many different models were released over the years with new features. The first model was the PC-9801, which launched in October 1982. It cost about 298,000 yen when it first came out. Later, the PC-9801F was released in 1983 with a faster brain. The PC-9801VM arrived in July 1985 and became a huge success. It used an NEC V30 processor to run at 10 MHz. This model helped the series sell 210,000 units in a single year.

Even though the PC-98 was powerful, things eventually changed.

For a long time, the PC-98 was different from IBM computers. This meant it could not run the same programs as other brands. As Windows became more popular, developers stopped making special software for it. Cheaper computers from other countries also began to enter the market. By 1997, NEC stopped making machines that worked with the old system. The world of computers moved toward one standard instead of many.

The PC-98 was a dominant lineup of personal computers manufactured by the Japanese company NEC. Produced between 1982 and 2003, this series included both 16-bit and 32-bit machines.

While these computers used standard x86-based processors, they utilized an in-house architecture. This specific design made them incompatible with IBM clones, which were the standard in other parts of the world. This distinction allowed NEC to establish a massive presence in the Japanese market. By 1999, NEC had sold more than 18 million units of the PC-98 series.

To understand why the PC-98 was so successful, one must look at the technical challenges of the Japanese language. Japanese writing uses multiple systems, including kanji, which consists of thousands of unique characters. Most global IBM clones lacked the graphics capabilities to display these complex characters easily. The PC-98 solved this by using specialized hardware. For example, the original PC-9801 used two separate $\mu$PD7220 display controllers.

One controller managed text, while the other managed video graphics. This setup allowed the machine to handle the intricate requirements of Japanese text and visual data simultaneously.

The development of the PC-98 was driven by a desire to bridge the gap between business and consumer needs. A developer named Hamada led the project planning for the series. He wanted a 16-bit machine that offered backward compatibility with the successful PC-8800 series. This meant users could still use their older peripheral devices, such as displays and floppy disk drives.

To ensure a strong software library, the team also developed N88-BASIC(86). Because they could not reach an agreement with Microsoft for a specific version of BASIC, the team wrote this code from scratch. To encourage growth, NEC provided 50 to 100 free prototypes and technical data to third-party software developers.

NEC released several distinct models that catered to different user requirements. The first model, the PC-9801, launched in October 1982 with a 5 MHz 8086 CPU. It featured an 8-color display with a maximum resolution of 640\times400 pixels. In 1983, the PC-9801F arrived, offering an 8086-2 CPU that could run at 5 or 8 MHz. It included a kanji ROM board containing 2,965 characters to assist with Japanese word processing. The PC-9801VM, released in July 1985, became a major milestone for the series. It utilized an NEC V30 processor running at 10 MHz. This model was incredibly popular, with annual sales reaching 210,000 units.

Market dominance was achieved through strategic hardware choices and industry cooperation. By 1991, the PC-98 held more than 60% of the Japanese personal computer market share. The series expanded from business tools into education and various hobbies throughout the 1990s. NEC also supported the ecosystem by allowing software companies to bundle certain versions of MS-DOS without paying a license fee between 1983 and 1987. This helped build a massive library of available programs. By 1987, NEC reported that one million PC-98 units had been shipped, supported by approximately 3,000 different software packages.

Despite this success, the PC-98 eventually faced significant challenges from global technological shifts. For many years, the Japanese market remained isolated because global manufacturers struggled with the language barrier. However, by 1990, improvements in CPUs and graphics changed the landscape. The introduction of the DOS/V operating system allowed IBM clones to display Japanese text using software fonts. This development gave international manufacturers a way to compete directly in Japan. As Windows became the standard operating system, software developers no longer felt the need to write separate code for the unique PC-98 platform.

The decline of the PC-98 was finalized by the rise of the "Wintel" era. An influx of cheaper clone computers from American vendors increased competition. Additionally, the popularity of Windows 95 reduced the demand for older PC-98 legacy applications.

Consequently, NEC abandoned its compatibility with the PC-98 platform in 1997. The company transitioned to producing computers based on the PC System Design Guide to align with the global standard. This marked the end of an era where a proprietary architecture could dominate a major national market.
