      Doh, yes...too much caffeine today. I too have a TDS3012.

      Yes, it's rather nice!

      I didn't know there was a VGA output option for that scope. Nice!

      Ok, this is getting weird. My "main" scope is...yes, a 2465A.

      Replace that battery, man!

      Sweet! Recently I was lucky enough to get an HP 3458A. That sits in
      the metrology area, not for general electronics work. (don't really
      need to adjust +5 in my PDP-11s to 8.5 digits!)

      I'm quite jealous of your 9010A.

      All sounds good to me. I especially like your dummy load selection.

      One of my companies in Maryland shared a parking lot with the Pace
      facility in Laurel. They were nice guys over there. It wasn't a
      "customer facing" facility, but when I picked up Pace gear from the
      local surplus places, they were great about getting me replacement parts
      and helping me get things running.

      I'm a wick man myself. I've tried 'em all, but I keep coming back to
      wick. Good-quality wick from MG or ChemWick, not the Radio Shack garbage.

      I'll have to take some shop pics soon. I only have a temporary
      electronics work area set up in my building now, until the renovations
      are done (or even started!), but it's working out great so far.

        They have gone up a little since I got mine for $20 9 years ago.

        > Have you done anything interesting with yours?
        Its been to VCF. I demoed it in store and non-store mode. The deflection
        isn't fast enough to keep up with the AX08 without some delays so I also
        brought another monitor that worked better for space war. I can't remember
        what I was drawing in store mode. It may have been spirograph type patterns.

        I may bring a RM503 this year since that a good period display for
        the PDP-8.

        My 547 and teletype made it on TV for 8 seconds.
