    Seems likely to be the same system. Nice looking system, but starting bid is way too much for an untested system. Even too much for a fully tested...

    Another factor that is pulling the value of your Rainbow down Alan, is that it also likely lacks the color graphics option. Since you only have the...

    This is almost as bare bones as a system could get. It was a CAPS-11 system. CAPS-11 is really slow, because the TU60 is really slow. You'll see...

    I saw the KI panel. I don't know if I will bid on it or not. It is quite nice, but not as
    good as the KA-10 panel you have. Sometimes I think back to your offer to trade
    it for my TC08. I have a feeling the KI-10 panel will go for some serious $$.
    How are things with you. Not much different here besides a few more people leaving
    our group. I have not been able to land a job back east as of yet.
