Trying out RIGOL's new 12-bit DHO800 on a real vintage project. Is it any good?

  Nice scope, been looking at these Rigols.

  You should tie that enable pin high to test it. &nbsp;Leaving it floating might have all kinds of odd results.

  Dave Jones made a video on how to properly ground a scope probe. One thing I remember is that the closest the ground lead is to the point being probed, the better the probing is (less induction from long leads). He even showed a ground lead that is like an inch long. I&apos;d say it would make quite a difference in the MHz range! :)

  Use all 4 channels of your scope. You can view the oe, dir, in and out at the same time in single shot and see what combination causes the line to ramp. Probably it is oe high, putting the device into hi Z

  This is definitely my favorite project of yours, always a treat to when you put out a video on this board!

  Wow... LAN port, HDMI, USB-C... Web control (which may explain slow boot... It&apos;s spinning up a web server), which is reasonably snappy... Seems like a winner!

  Nice review, I like that the review was in the context doing real world tests.

  Proper Review and Dave Jones in one sentence? <br>&quot;Your guess is as good as mine&quot;...

  you have a resisting rising: Look&apos;s like a top transistor is dead into the push pull of the bus chip driver.

  I think that that &quot;weirdness&quot; on the ISA bus is normal, I&apos;ve observed similar signals on other PC motherboards. It&apos;s the capacitance of the trace that charges up pulled by that resistor network to Vcc. The bus is just left in Z-state when not in use, that&apos;s why do you see those slow rises.<br>Congrats on the scope though!

  Now you can unlock all the features (50Mpt, 250MHz, extended decoders, etc.) of the all DHO8xx and DHO9xx series with the DHO800-900 Sparrow Extended GUI v0.7.1 for the 00.01.04 firmware
