A80486DX2-66 / L434004Q ES / &EW5V1X Q0652

A very rare engineering sample of the lastest stepping of the 486 DX2 66. Introduced in August 1992 with the 0.8 µm process, the last revision of this processor was produced in late 94 with the 0.6 µm process. This sample was produced in mid-94 and was the first 486 DX2 66 to use the 0.6 µm process.
