[time-nuts] Divide by five

[Bob Bownes]

I'm surprised no one has suggested 74F161 or other F series. Power hungry, but rated to in excess of 100mhz, some vendors as high as 120mhz, at ordinary temps. I will have to look, but I might have a tube or two of them in the basement. I know I have most of the other 74F.
