CPU 333 MHz PowerPC G3 with 66 MHz system bus and 512 KB backside L2 cache. Generic clock-only record does not infer a silicon supplier.
GPU ATI RAGE Pro Turbo with 6 MB video memory. The retained maker resolution table includes a conflicting 2 MB column; The exact Macworld review and EveryMac specification identify 6 MB for this revision.
Memory type 32 MB SDRAM in two SO-DIMM slots. Current retained maker sheet gives a 128 MB maximum; older Apple developer history and contemporary Macworld review give 256 MB. The conservative configurations retain the current maker maximum.
Storage type 6 GB ATA hard drive and tray-loading 24x CD-ROM. Display
Screen size 15″
Resolution 1024 × 768
Refresh rate 75 Hz
Display type Nominal 15-inch CRT with 13.8-inch viewable diagonal; not a fixed-native-resolution LCD.
