You are purchasing a newly made ROM 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 memory chips, and has been individual tested. Modules are guaranteed to be functional.
