There are some real oddballs - 7459 is one (there was
a thread on this a
7456 and 7457, which are /50 and /60 counters (to get 1Hz from european
and US mains). AFAIK they're the only TTL chips in 8 pin packages.
And the 74S262, which is a teletext-compatible character generator ROM.
Very few databooks list that one.
