Apple's system knowledge

MAC OS is a smiley MAC from the front, left and right, symbolizing friendship, openness and compatibility. G3 series system bus 66MHZ SCSI can string seven peripherals, CPU ID7, internal hard disk ID0, interface with 25-pin D-type connection and 50-pin D-type 168-line DIMM RAM can be expanded 768MB, do not need to install in pairs, 64-bit data Width, slightly different from PC memory, cannot be used interchangeably, POWER G3 uses a higher speed synchronous SDRAM, can not use the previous 168 line memory


Apple generally uses SCSI hard disks, but G3 uses high-speed EIDE hard disks. The hard disk format is HFS (Hierarchical File System), HFS+. Supports long file names (31 characters), uses 64-bit addressing in G3, supports files of 65536, and has a maximum of 2 GB of files. CD-ROM also has SCSI and IDE points. In the past, SCSI used industry standard ATAPI in G3. Supports DVD and UDF MAC OS system software and core parts are built into the motherboard's ROM and SYSTEM FLODER. You can install multiple different systems such as English, Simplified Chinese, and Traditional Chinese according to different needs. However, only one of them can be activated at the same time. In the system folder, SYSTEM and FINDER are the two most important and basic files. Files include: support for basic system software resources, support for multilingual (scriptER); different keyboard layouts KEYBOARD LAYOUT and alert SOUND. FINDER is actually an application software. The main task is to manage the entire desktop environment, spend +Q to exit, spend +W to close.
