Yes, that´s my impression too.

But that,s very easy (now that I know how to get them working) If you build a circuit as shown on my site:
you can connect it to a mikrocontroller (or any other logic device) without any aditional components. EG1 + EG2 is connected to the guide cathodes of the Dekatron and A is a open collector output that can be directly connected to a pin of a microcontroller too.
To make it "move" you have to give a high signal to EG1, then a high signal to EG2, then a low signal to EG1 and then a low signal to EG2. Because the the Dekatron can not follow if the switching speed is to high, you have to wait for al least 0,25 milliseconds after every change of signal on EG1 and EG2. That means:
EG1 = 1, wait 0,25ms, EG2 = 1, EG1 = 0, wait 0,25ms, EG2 = 0.
On my clock, to give it a smooth move from pin to pin, I put a delay of 5ms instead of 0,25ms.
Hope my English is good enough to make this explanation understandable.
