I forgot that I had this. I don't know if it counts because it does say sample.
According to sources the 487 introduced in April 1991. This one is 1991, Week 09.  |

I have 4 of those i487SX:
A80487SX SZ494 C2160544 B0
A80487SX SZ494 C2340831 B0
A80487SX SZ494 C2470480 B0
A80487SX SZ494 C2470480 B0 (really!)
Don't know why, but two of my i487SX completely have the same serial (C2470480 on top and 92365236CA on back). Also my oldest i487SX (C2160544) has additional top markings like that one of CPUbar.
Does anyone know what these markings have to say?
Best regards, Xaar.
