    I was recently looking at my old 486 M/B running a 486 DX-2 at 80 Mhz. (Overclocked from 66 Mhz.). I noticed that it has three brown slots almost like AGP Slots, but they were placed at the back of the ISA Slots, so I think they can't be expansion slots.What are they?

    A blast from the past! :) Those are VESA Local Bus slots, the first attempt at a faster bus than the old ISA bus. They basically allow connection directly to the processor data bus, and were very touchy in real life. I just tossed the last of my VESA LB cards a month or so ago. :D

    Hey thats a great overclock for that chip (21%). I remember people would be bragging if they 10mhz extra out of those things.

    You must be water-cooling!

    Then I suppose that the VESA LB Slots are an attempt between the ISA and PCI slots.Right?But, how do you insert external peripherals into these cards (they are placed at the back)?

    I overclocked the 486 without any special cooling- Serious!
    I used the FSB for overclocking (40x2, the actual being 33.33x2)
    Btw my country is a hot one.

    Yep, it was in the same era as the EISA bus, that was the one that Compaq was pushing back then. The EISA bus was certainly more robust than the VLB, but it was also more expensive to implement. Finally PCI came to rescue us from the bus wars until AGP and the communications riser came along to muddy the waters again! :D
