NS486SXL-25 ES (Week 42, Year 1996)
ES9642ABE4 NS486SXL-25 DD SAMPLE
Here is a rare evaluation module used to debug the 486SX clone from National Semiconductors. NS produced only two different part numbers (486SXL & 486 SXF) for the embedded market before leaving the x86 business. This sample was produced in October 1996, many months before the official NS486SXL launch that occurred in 1997.
