  • You wanna be my PAL? [Identifying PALs on 15F7659 / 8570-Axx 386 Power Platform]

    Folks, I need a good, clear pic of the 386DX-25 "Power Platform" to look
    at it's naughty bits.

    The money shot are the PALs U3-U7. The image on flea-buy is not klar enough.

    I see dead people... er, no, 15F7645, 15F7644, and things that are
    suggestive.

    We have a clear picture of an 8580-Axx sysboard, and bless their hearts,
    they used the Japanese component ID labeling.

    MAYBE IBM used the same glue logic on both 82385 / 64k L2
    implementations....
