Pins and overall CPU in great shape for its age! This CPU has been stored in a box since the 1990s.

The first "unfinished" K5 was codenamed SSA/5 which had bugs in branch-prediction and in the level 1 cache. Earlier units were sold as AMD 5k86.

This unit is an AMD-SSA/5-75ABR, equivalent to a Pentium Pro with some unique advantages and disadvantages. It fits Socket 5 and Socket 7 (second-gen Intel Pentium). It is 75MHz with a 50MHz bus speed.
