Description
This Apple 661-0494 module represents a 256 kilobyte (KB) SIMM (Single In-line Memory Module) with a 120 nanosecond (ns) access time. SIMMs were a common form factor for memory modules in the late 1980s and early 1990s, and this particular module, with its 30-pin configuration, was typically found in older Apple Macintosh computers. The relatively slow access time of 120ns reflects the technology of the era.
