Although primitive, the PC launched at a competitive price and paved the way for NEC's eventual dominance of the Japanese PC industry in the s and s. Another expanded version with extra graphics and sound support for the mkIISR. An expansion board developed by HAL Labs that enabled more advanced graphics and sound. Advanced embedding details, examples, and help! NEC established an early lead in the Japanese home computer industry with the release of the PC From there, NEC expanded and diversified its lineup with a three-pronged approach.

For the home and family market, there was the low-cost PC series, featuring a cartridge ROM slot and novelty features like speech synthesis. For the electronic hobbyists and amateur programmers, there was the midrange PC series.

However, the biggest selling point was its backwards compatibility with PC software, providing a smooth upgrade path for customers who had already bought into the NEC ecosystem. Games were not the primary focus, as NEC intended to sell its high-end 8-bit machine to a whole spectrum of customers ranging from computer enthusiasts to small businesses and educational institutions.

The PC was popular from the moment of its release, but soon after, rival companies released their own competing computers like the Fujitsu FM-7 and the Sharp X1. These computers offered compelling new features that outclassed the PC, especially for games. Meanwhile, in , the mainframe division of NEC released a new bit computer called the PC, which swiftly became the computer of choice for business and office work. By , the PC was having an identity crisis. It was a solid all-round computer, but it failed to excel at anything in particular.

Something new was needed to keep the PC relevant. The SR, or "Super Revision", featured a number of improvements, including a much faster graphics subsystem offering a wider palette of colors, but the crown jewel of the SR refresh was the introduction of a brand-new sound technology for personal computers: FM synthesis. FM synthesis is a digital synthesis technique for creating complex sounds by modifying a base waveform the carrier with another waveform the modulator.

A short time later, Yamaha developed a range of 1-chip FM synth implementations suitable for mounting onto standard circuit boards. Meanwhile, FM synthesis was also beginning to be used in some of the latest arcade games, such as Marble Madness, Ghosts 'n Goblins, and Space Harrier.

Compared to the earlier programmable sound generator PSG chips like the APU inside the Famicom or the ubiquitous AY chip, FM synthesis produces smooth, glassy tones which are digitally flawless, but also complex enough to avoid sounding "chippy" or "beepy".

In essence, NEC brought the latest arcade-quality sound to home computers, and the difference was astounding. The other computer manufacturers rushed to catch up, and FM synth quickly became the de facto sound of Japanese computer games. The inclusion of FM synthesis, along with the much improved graphics architecture, redefined the PC series as a computer for gamers and creative hobbyists, and secured its position as the quintessential Japanese computer of the s.
