You are purchasing a newly made memory module manufactured by myself. The memory modules have been engineered using high quality 4 layer gold plated printed circuit board with internal power and ground planes for maximum data integrity and low power supply ripple. Each memory modules has been professionally hand assembled using new old stock Hitachi 50ns SRAM memory chips. Modules are guaranteed to be functional and have been fully tested in a vintage PowerBook machine.

Low power: Instead of using original pseudo-static RAM (PSRAM), my modules are using more costly real static RAM (SRAM) which do not need refresh and use a third of the power used by original PSRAM.

Compatible with:

• PowerBook 160
• PowerBook 165
• PowerBook 180

This module will not fit the 165c and 180c Color Powerbooks.
