HEPABAL - Very large incrementer (64 hexidecimal places)

[asterick]

I'm not taking full credit for this, as I didn't come up with the thing entirely by myself (the carry logic for instance)

I think this is the largest incrementer possible (I think)

That doesn't work all the way.  The first 16 digits go just fine, but then on the next carry it increments the rest of the system!

No, it works fine as far as I can see. It's just that the count doesn't start at zero but at -256 (if interpreted as a 2's complement number) and than all the Fs are changed to 0s when it goes from negative to positive. I guess asterick made it that way to show that the caries work (or else you would have to wait an eternity to see them all change).

how did you watch it for that long

It only takes approx 256 tics. This is the point where the first two crates reach F (16 digits for the second crate, or 256 if the first 16 cycle 16 times) , "carrying" the next digit all the way down the line.

Gorgeous work asterick.

Here's an even larger one with 80 digits and a faster carrying between rows.  It's based on the same mechanism, but the removal of all the furnaces except for the last one allowed me to collapse three rows at the top of each layer into a single row.  rybicol.
