On my old Gateway 2000 486 DX-2/50 I have a Gemini baby-AT motherboard from Micronics. It is an ISA only board. It came equipped with the DX-2 cpu and an empty socket for the Weitek co-proc.
What I am trying to determine is what CPU I have! Yeh, that's right! The 486 cpu here seems to be about 1/3rd the size of all the other 486/487 DX/SX/DX-2 chips I've always seen and known. There is a heatsink glued on the chip and it is socketed. It shows up in the bios as a genuine i486 dx2. All my literature and manuals and advertisements (I have all of it!) say it is indeed an intel chip.
I have this PC in storage, pretty well sealed up and I don't want to unpack and unseal it for a while yet. But can anyone tell me about this cpu?? Were clones of the 486 available then? This is late 1992. Or did intel make special oem chips or something? Or is this from a 3rd party mfg?
Also. One other thing, the system comes with cache 32K static ram cache on the mobo. And no matter what I did with it, it didn't make a difference if I had it turned on or off via the dip switches and bios. I could not see any changes in the benchmarks of the day. I'm wondering if this is that "fake-cache" thing that was going around in the pentium days.
