11.3-inch 800 × 600 dual-scan passive-matrix FSTN LCD with 16-bit colour. Apple's family video table identifies cs displays as FSTN, and NotebookBlog confirms the exact 166 MHz sample's passive screen; the later Service Source cs/166 configuration entry instead says active matrix, conflicting with those sources

CPU
166 MHz PowerPC 603e with integrated PMMU and FPU, 64-bit data path at 33.3 MHz and 32 KB L1 cache. Support and Apple Facts January 1998 specify 128 KB L2; Service Source's cs/166 entry instead says 256 KB

Battery life detail
Removable 30 Wh nickel-metal hydride battery; Apple Facts claims two to four hours depending on usage and configuration. It gives PowerBook 1400cs weight as 3.0 kg with floppy module or 3.15 kg with CD-ROM; exact cs/166 support instead lists 6.6 lb with accessory-dependent weight. Support's six-inch height conflicts with Apple Facts' two inches; metric thickness and depth remain omitted because maker conversions also disagree
