    Did you ask the seller if that spot is actually there, to make sure it isn't light and shadows reflecting off the screen?

    amount of cache vs amount of memory.

    When it comes to cacheing ram, I understand one needs:
    64KB for 8MB
    128KB for 16MB
    256KB for 32MB
    512K for 64MB
    ..and so on.

    Is there any advantge to be had by having more than required...

    Yeah, it is pretty much right on 5 volts in the other three corners. And it has had all the major 10uf tantalum replaced, about 40 in total. And I have tried 2 different PSUs. Made sure the crystals...

    It is indeed too low. 4.5 to 5.5 is what my ram requires as well. I am baffled as to how the board is even giving any kind of message at all. At any rate, I believe those resistor arrays have failed...

    Is there any particular reason you you 3.4 instead of 4.1? 4.1 is, as far as I know, the last one that will boot on a 386.

    35v caps on 286 board?

    I've got a 286 board I want to recap, but it has 35 volt tantalum caps all over it. Is there a reason they would have used these over 16 volt caps, other than maybe they got a good deal on 35 volt...

    Can you post a pic? One switch should be for cache, the other should be to toggle the 286 or 8088. You're not sticking it in slot 8 are you? (only if you have an XT)

  23. Are there any 286's that deturbo to 4.77Mhz?

    Preferably an 8/10/12Mhz machine. I actually have a 286 powered XT board (Hedaka 919) that does this, but I was wonder if there are any proper fully 16 bit boards that de-turboed to 4.77Mhz?

    Can the IBM 5162 be upgraded, speedwise?

    Provided the correct Crystal, CPU, and RAM is in place, can the XT286 go faster than 6Mhz, or does it also have those ROM routines that prevent this like some of the ATs do?
