72 Pin Simm Appraisal

Vintage Compaq 72-Pin SIMM Memory Module with Toshiba Chips

This is a vintage computer memory module, specifically a Single In-Line Memory Module (SIMM), likely from the mid-1990s. The unit features a green printed circuit board (PCB) with a single row of gold-plated or tin-plated connector pins along the bottom edge, characteristic of the 72-pin SIMM standard. Mounted on the board are multiple black integrated circuit chips. Notable markings include a white label on the lower chip identifying it as a 'COMPAQ' part with the serial number '185172-002'. The upper chip bears a 'TOSHIBA' label with technical specifications 'THM322005ASG-80' and '9446 USA', which indicates a manufacturing date around the 46th week of 1994. The module has a length of approximately 4.25 inches. Physically, the item shows minor signs of aging, including slight yellowing of the paper labels and some oxidation on the solder points, though there are no visible signs of traumatic mechanical damage or burnt components. The presence of both 'Compaq' and 'Toshiba' branding suggests this was a high-quality OEM part produced for Compaq's proprietary desktop or server systems of that era. The construction quality is indicative of industrial standards from the early 1990s computing market.
