content: Is that a Trinitron color CRT? I'd have dragged it home too, but then I'm a sucker for CRT displays, especially top notch color ones. Have a peek inside the thing, with it being that dead the problem might turn out to be something fairly simple. Check the voltages, make sure any socketed parts are fully seated, cables connected, etc. Check the CPU clock, watch the reset line and see if a watchdog is rebooting it.

content: Nice looking vintage scope. I would have a problem letting it get tossed as well.I have an old HP network analyzer that would not boot. It turned out to be the battery. In my case, after it was replaced, it was fine.When you get it running, post a few pictures of it.

content: Just be thankful that you can still find items like that; In England, we have nothing in the way of test equipment being thrown out.Same thing with my other love, keyboards. I would love a hammond M100. There are dozens of them in the states, free, the owners want rid of them. Look over here, they go for around $4000

You can easily sell your unit if you don't have a probe to go with it, or pick up a probe to give yourself a nice current measuring setup.

content: Congratulations! Time to put this "vintage junk" through its paces - the upcoming thanksgiving week is perfect for that (if you are able to take time off)

content: Wow that was almost too easy. You'd think they would have designed it to display an error message if the battery is bad rather than just not boot. Looks like a nice scope.
