Description
Intel Pentium 166MHz CPU Processor A80502166 SL24R Socket 7 P54C
The Intel Pentium 166MHz (A80502166, SL24R) is a first-generation Pentium processor built on Intel's P54C architecture. Running at 166MHz on a 66MHz front-side bus, it fits the industry-standard Socket 7 platform and was among the faster entries in Intel's original Pentium lineup before the Pentium MMX and Pentium II superseded it.

Applications
The Intel Pentium 166MHz Socket 7 processor was a mainstream desktop CPU of the mid-1990s, widely used in business and consumer PCs running Windows 95, Windows NT 4.0, and DOS-based software. Socket 7 was an open standard supported by Intel, AMD, Cyrix, and IBM, making these boards and CPUs interchangeable across a range of mid-decade ATX and AT form-factor systems. Today this processor is sought after by vintage PC enthusiasts restoring period-correct Socket 7 builds, collectors of classic Intel hardware, and system restorers replacing failed CPUs in legacy workstations and embedded industrial equipment. The P54C Pentium predates MMX technology and the Pentium II slot-based architecture — it represents the core of mid-1990s x86 computing before the segment bifurcated into MMX consumer and Pro/Xeon server lines.
This Intel Pentium 166MHz CPU (A80502166, SL24R) has been tested at our facility and is in good working condition. The processor is a Socket 7 P54C-architecture chip. The gold pin array on the underside is intact with no bent or missing pins visible. The top lid shows light surface scuffing typical of pulled/used processors.
