[QUOTE=mdettweiler;257902]Finally--I've at long last found a prime on the 7th Drive! :big grin: ...

This is my first top-5000-worthy NPLB prime that I've found since June 2009! :shock: (I reported one in September 2010 but that was actually one of Gary's that he "gave" me because he lost a bet.)[/QUOTE]

Congrats! Hopefully my drought of NPLB primes will end too - I've done 10857 candidates with 0 primes on port 9000. But I can't complain too much, as I recently got a large top 5000 prime on CRUS's base 16. :smile: And 10857 is not nearly as bad as how many you had with 0 primes! (~36598 on port 9000)

It's about time! lol Anyway, congrats. When counting port 9000 and the CRUS port, I think you had gone over 50,000 pairs without a prime; a remarkable drought.

Plenty of time for you to find another one Max!
