Tektronix 422

Just the instrument itself. So, first I want to see if it functions at all. I don't have the power cord, and it takes an odd six-pin cord. The internal batteries are, of course, discharged. Anyone have a power cord, or source for one, or at least the plug? If it powers up, I would like to get it apart. I got the power supply off with no problem. Anyone have a basic assembly diagram? If it then seems worth while, I would like the manuals and probes. Suggestions? I know it is only 15 MHz, but that should be plenty for computers running no faster that 4 MHz, correct? All help appreciated. Louis
