So, I was wondering what that benchmark/screensaver/demo at 0:30 is? I ask, because that's an excellent render of a Sony Sobax calculator (That chassis suggests an ICC 400, 500, or 600 series). I restored an ICC-600W back in 2013, and can honestly say, with select a few exceptions, they do a very good job getting the little details correct. The Nixie tubes, the transformer, capacitor, and resistor in each driver circuit, the left two neon lamps, the chassis, even the decimal slider lever and the backplane PCB behind the nixie driver PCB are seriously mostly accurate!
it ain't perfect. I mean, it's clearly not 100% accurate. Honestly though, that render was obviously created by someone who knew what they were recreating.
Close enough definitely counts for this one!
I'd love to know what that render is from, and where I can get it.
