the CPU daughtercard for an Apple Macintosh G3 PowerBook Pismo. The computer is M/N M7572, known also as "Firewire" and "2000"
The card is the 400 MHz version, Apple Part Number 820-1074-A. It carries the processor, L1 & L2 caches, two memory slots and other things I don't know about
The memory slots are filled with (upgraded) 256 MB PC100 RAM modules
The unit is complete, has no mods or repairs and functions just as Apple designed it. It is Apple-original except for the RAM upgrade
