Ibm Memory Module Appraisal

Vintage IBM 72-pin SIMM RAM Module

This is a vintage Single Inline Memory Module (SIMM) computer RAM stick, notably featuring branding from IBM. The item consists of a dark green printed circuit board (PCB) approximately 4 inches in length. It features a 72-pin gold-plated edge connector along one side, characterized by a distinct notch in the center and a corner cutout for keyed insertion. On the face of the module, two large integrated circuit (IC) chips are visible. The top chip features a white label with the iconic 'IBM' logo. The lower chip bears a label with technical markings including 'SEC Korea 9819H' and a serial/part number 'KMM5321204CW-6'. This indicates the memory chips were manufactured by Samsung Electronics Company (SEC) in Korea, likely around the 19th week of 1998 based on the date code. The construction quality is typical of high-end enterprise hardware from the late 1990s, utilizing surface-mount technology. Condition-wise, the module appears used, showing minor scuffs on the labels and slight tarnishing on the contact pins, though no physical cracks or missing components are evident. This type of memory was standard in mid-to-late 1990s personal computers and servers.
