SIMM 8MB

A SIMM 8MB refers to a Single In-line Memory Module with 8 MB of RAM capacity. SIMM was a type of memory module used in computers and other electronic devices primarily in the 1980s and 1990s.

Characteristics of SIMM 8MB:

• Capacity: 8 MB (megabytes) of RAM
• Form Factor: SIMM (Single In-line Memory Module)
• Bus Width: 32-bit (for 72-pin modules) or 8-bit/16-bit (for 30-pin modules)
• Memory Type: DRAM (Dynamic RAM), FPM (Fast Page Mode), EDO (Extended Data Out)
• Voltage: 5V (most models)
• Connector Types:
  • 30-pin SIMM (older, 8-bit or 16-bit modules) – used in IBM PS/2, older 486 PCs, Amiga 3000, Amiga 4000
  • 72-pin SIMM (newer, 32-bit modules) – used in Pentium 1, Amiga 1200 (with expansion), Macintosh Quadra, some servers

Usage:

• Personal Computers (PCs) – mainly 486 and Pentium 1-era machines
• Workstations – certain Macintosh Quadra and PowerPC models
• Retro Computers & Amiga Systems – memory expansion for Amiga 1200, Amiga 4000
• Printers & Network Devices – expanding memory in older laser printers and routers

Difference Between 30-pin and 72-pin SIMM:

• 30-pin SIMMs – must be installed in pairs on 486-based motherboards
• 72-pin SIMMs – fully 32-bit, can be installed individually on motherboards that support SIMM modules

Availability & Price Today:

SIMM memory is now obsolete but can still be found on online marketplaces (eBay, Amibay, vintage hardware shops). Prices range from $5 to $25 per module, depending on the type, condition, and demand.
