I was tempted to try to read it with my CCD reader from the video on the computer screen. Similar displays (Hollerith, paper tape) wouldn't be hard, and would be just as (not) useful. I'd be tempted to make an old A-scope style radar display with a few lines of shark-fin looking pips (hours, minutes, seconds), and have the pips slowly meander across the screen. A few index marks would make it easier to read. I don't know how hard that would be to code up, but the existing displays cover a lot of ground, so I'm guessing it would be feasible. I'm hoping to get a look at the code soon, idiosyncratic or not. I have a fondness for strange real-time code. > I have to admit I like those voltage multipliers; they take more space than > other solutions but have no semiconductors to let the magic smoke out of. They don't? What are you using as rectifiers? I can imagine a 50Hz supply with 5642s as rectifiers, but that would involve adding quite a few filament windings to the power transformer. Which reminds me, the article mentioned adding a heater winding, but I didn't find a description of how it was implemented. > I very much agree - time to source a chunk of brass and get it turned.

I'd be tempted to make a slide out light shade as well, either a hood like a traffic signal, or a tube like the old Waterman pocket scopes. Not that it's necessary, but it's another fun thing to fiddle with, if you actually want peoples' fingers near the CRT. I love the Latin markings too.
