Ring counter, made out of Potato Semiconductor PO74G74A's? Except those
don't come in DIP as far as I know. But consider that the spacing on a SOIC
is just the same as spacing on a TO-92.

I know that ECL dividers/prescalers e.g. 11C90 used to come in DIP but I
only see SMD ECL now. e.g. MC10EP139.
