The PC-9801 is a series of desktop and laptop computers developed by NEC for the Japanese home market. The PC-9801 was released shortly after the PC-8801 series and featured technically superior hardware at greater expense. The original model ran at 640x400 resolution with an unusual 8-color display (3-bit). The first computers in the line used Intel CPUs, but in 1985, NEC tried swapping them out for their own clone chips. This didn't last, and by 1986, all CPUs were back to Intel until the end of the product line. The earliest models featured a proprietary version of NEC BASIC, later models came with a localized version of MS-DOS, then Windows 3, and finally, Windows 95 and 98.

Models

NEC released dozens of models in the PC-9801 line, although most were just minor increases in CPU speed and various disk drive configurations. The first model used an 8086 5 MHz CPU, by the early 1990s, they came standard with a 386 16 MHz, and the last model, released in 2000, featured a Celeron 443 MHz. Several models are shown below.

Music and Sound

For the first several years of its run, each of the models of the PC-9801 came equipped with just a PC Speaker. NEC began producing sound cards for the system in 1985, and later, in 1992, they began building audio chips right onto the motherboards. Around 1994, NEC dropped the on-board audio and went back to the PC Speaker requiring users to buy a sound card for all subsequent models.

Several sound cards were made for the PC-9801, and many external devices like the MT-32 and FB-01 were compatible with it.
