Creative Labs Sound Blaster PCI 128 CT4750 Sound Card

What is it?

The Creative Labs Sound Blaster PCI 128 (CT4750) is an internal 32-bit PCI sound card from around 1998, designed for the era of Windows desktop audio and PC gaming. It is a period choice for retro Windows 9x and XP builds.

Why choose it?

Bring late-1990s PC audio back to your retro desktop, from game soundtracks to music playback. The CT4750 combines analog audio connections, a legacy Game/MIDI port, and an internal CD-audio connector in a PCI expansion card.

Legacy Windows driver support makes it suited to period-correct builds. For pure-DOS gaming, compatibility can be more limited than with older ISA Sound Blaster cards, so it should not be treated as a direct replacement for an SB16 or AWE32.
