That's pretty slick, Russ!

I don't have one of those "fancy" 'scopes that captures the images, so I take a snapshot with a digital camera. The more modern of my two workhorses displays the scale units and, of course, one can capture the knob positions if one wishes, but hte one I use most is just an old TEK '475A with the DM44, and I can operate it without even looking at the instrument except to watch the display, which is why I like it.

I've found that most 805x's that I have lying about tolerate the addition of a gate on the X2 output of the oscillator. This means that it can feed an external timing circuit without hampering the MCU's operation. I'd like to find out whether there are any "standard" sort parts that don't tolerate the extra load. I doubt that there would be, but the question has come up a number of times, including here in this forum, whether one could grab the oscillator and use it for something useful outside the MCU, perhaps even to operate yet another MCU. All the Maxim/Dallas, Intel, AMD, Signetics, and Philips chips I have where I can experiment with them, happily seem to tolerate the extra load.

Thanks for contributing this information.
