History of most common PC-98 sound hardware:

1992: The Soundblaster 16 which has an YMF262 (enhanced YM3812) and increased fidelity in playing samples (It also had a variant released for the PC-98).

1989: The Soundblaster (Same as the Adlib, except with the ability to play samples).

Also in 1987: The Roland MT-32 (32 channels LA synthesis) connected via MIDI to an MPU-401 card (of which there was a variant for the PC-98).

1987: The Adlib with a single YM3812 FM synth (9 channels or 6 with 5 perc channels 4 waveforms).

1986: The Covox Speech Thing, which was a DAC connected to the parallel port.

1983: (PCjr / Tandy 1000 only) One TI SN76489 (3 channels pulse, 1 channel noise same chip used in the Master System).

1981: 1-channel PC speaker, produces a pulse wave (however it is possible to force samples out of it).

History of most common PC compatible sound hardware: However, because they need to interface with the underlying hardware in different ways, Win9x for IBM PCs and Win9x for PC98 are quite different, and Japanese Win9x CDs include separate builds for IBM PC and PC-9801.Īnd of course, don't forget the sound differences: Both PC-98s and IBM compatibles only had a PC speaker during their early days - but from there they diverge.

Starting with Windows 95, the OS abstracted away enough of the underlying hardware so that software built for Windows 95 will essentially run on any computer running Windows 95. Anything that goes beyond the most basic I/O will crash and burn. IBM PCs outside Japan obviously lack this chip, so PC-9801 programs with Japanese text will not display correctly on an IBM PC.Įssentially, the only cross-compatible programs are the ones that never leave the realm of the CPU, like simple command-line programs. PC-9801 used a built-in kanji rom chip for Japanese text display. Ordinary PC-9801 output is 640x400, 16 colors, 56Hz refresh, 24kHz horizontal frequency. PC-9801 graphics subsystem is completely different than Western CGA/EGA/VGA standards. On a PC-9801, A: is always the drive you booted from. On an IBM PC, the floppy drives are A: and B: while the first hard disk is C. Drive letters are assigned differently.

Hard disks use a different type of partition table IBM PCs of the 80s and 90s used a mix of 8-bit and 16-bit ISA buses before being replaced with PCI. PC-9801 used C-bus, a 16-bit data bus designed by NEC. BIOS, port addresses, memory map are all different PC-9801 MS-DOS is essentially a modified port of IBM PC-compatible MS-DOS.Ĭombined together, an Intel(-ish) CPU and a Microsoft(-ish) OS mean that the PC-9801 can read and execute IBM PC-compatible software to a degree, and many basic command-line utilities will work fine on either system.īut beyond that very basic level of compatibility, the machines are really quite different. The pc-9801 also runs MS-DOS, but it's not exactly the same as the MS-DOS in the West. Early pc-9801 models were equipped with intel-compatible chips designed by NEC (like the V30), but after a time intel chips like the 286/386/486/Pentium/Celeron were used instead. Like the IBM PC, the PC-9801 uses a CPU that supports the x86 instruction set.

It might make sense to talk first about why IBM PC-compatibles and the PC-9801 series are similar, before moving on to the differences.
