> 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. -tony
