| It almost looks like a pentium overdrive socket, but it's not missing the pins in the corner like it's supposed to be, and it's labeled as a 486.... I'd be curious to see the top without the heatsink. Weird.... |

I'm unaware of any x86 processor with 208 pins. I would just remove the heatsink, it's more like an OEM cooler than a regular Intel one, so shouldn't affect the value.

Yeah, that is the same package. Dates are 21 months apart, so it will be interesting to see if it's an earlier version of the same model

i was afraid to crack the chip, but I was able to remove the heatsink. we all expected something on the chip. well, there is nothing, only some
hand written letters exactly under the really hard glue:
something like " CYC AT ICE " or like that
its hard to identify.
