: Interesting. How do we tell which ASIC we have?

If you have a 10/64 then you DO have the new ASIC, if not I wouldn't try 
it unless you are rolling in cash.  BTW, anyonw know where someone got 
the idea for 20 ns RAMS?  I did some formula plugging and got only 70ns! 
Someone care to explain the formula and how they got 20ns?  I am running 
10.5 MHZ. What speed do I need.  My calculations tell me 100ns!
