INtel 486 DX2-66, GOLD / BLACK backing

[sammyc]

Had some more CPU's arrived today, along with them several 486 CPU's. I happened to notice that one of the backs of the 486 DX2-66Mhz was black. I am assuming that this is a rare CPU as I have about 30 Intel 486 DX2-66's and this is the only one with a black backing.

Can anyone confirm that this is in fact a rare CPU and why it is different?

The black DX2 is Intel i486 with write back cache, i.e P24D instead of P24C core

It is still considered as a common cpu, just a little harder to find than normal one
