        case while it's still plugged in (which I think I will keep because 3 Sol
        guys I have spoken to already said they've seen it before it was common
        enough hack because "it's an annoying piece of metal" (I guess if my purist
        OCD kicks in, I can simply weld a small piece of metal in and repaint the
        area, hey I am a car guy)...

        like getting the mustang with a nicer freeflowing chrome air cleaner bought
        the week the guy picked up the car from ford... I think if it works, I may
        keep it, since the SOL not like a normal S100 system where you lose the
        entire original processor card to swap in a Z80. I'll just keep my eyes
        open for a date correct 8080 that I can grab cheap for the next owner of
        the system (I'm not planning on selling it, but as time goes by you never
        know)

        1977 Z80 CPU (not a Z80A). The keyboard was plugged into this setup... So
        I'm guessing this was done so the owner could have 80 column stuff... I
        think I need to research if this card has value, the CPU being white
        ceramic and a non A, may be worth more than the card.

        This one should be a keeper, while I'm not big on floppy drives, this card
        seems pretty cool, though it may just sit in a box or be used for a trade
        or something).
        >

        is from the limited information google provided you needed static ram for
        the Dutronics CPU upgrade to work right, so this setup worked at some
        point. I guess I'll keep the card until the system is up and running, then
        I'll look for a bunch of smaller 1977 dated memory cards. I don't really
        want more than 32k anyway...
