The 4th Gen Zaurus SL-C continued the clamshell design introduced with the SL-C700, but brought a substantial hardware upgrade with Intel's 400 MHz XScale PXA255 processor and 64 MB of SDRAM. The SL-C750 and SL-C760 retained the distinctive two-way design, in which the 3.7-inch VGA touchscreen could rotate through 180 degrees and fold back over the keyboard for a compact PDA-style viewing mode. Their 640 × 480-pixel, 65,536-colour transmissive System LCD used Sharp's CG-Silicon technology, while the keyboard provided a full QWERTY layout for text input. Both models also supported SD memory cards and CompactFlash Type II cards.
The SL-C750, SL-C760 and later SL-C860 shared essentially the same hardware platform, with differences primarily in internal Flash memory, battery capacity and software. The C750 provided 64 MB of Flash memory, while the C760 doubled this to 128 MB and used a larger battery. The C860 retained the C760's hardware configuration while adding enhanced software, most notably built-in Japanese–English and English–Japanese translation and USB storage functionality that allowed a connected computer to access cards inserted in the Zaurus. All three ran Sharp's Linux-based OpenPDA platform and represented the mature form of Sharp's compact VGA clamshell Zaurus design.
An optional Sharp CE-AG06 CompactFlash camera card could also be attached, adding digital photography capabilities with its 350,000-pixel CMOS sensor, VGA-resolution still images, 2× digital zoom and manually adjustable focus down to approximately 6 cm. With Sharp's Video Camera MORE software, the camera could also record low-resolution video at up to 320 × 240 pixels.

Released in May 2003, the SL-C750 was the first device of the fourth-generation SL-C series and the successor to the SL-C700. It introduced the faster 400 MHz PXA255 processor and 64 MB of SDRAM while retaining the compact clamshell design and VGA System LCD. Its 64 MB of Flash memory and approximately five-hour continuous-display battery life distinguished it from the higher-capacity C760.

Released in June 2003, the SL-C760 was the higher-capacity version of the C750, combining the same 400 MHz PXA255 processor and 64 MB of SDRAM with 128 MB of Flash memory and a larger battery for longer operating time. Apart from these differences and associated software, it retained the same clamshell body, VGA System LCD, keyboard and CF/SD expansion arrangement as the C750.
