Which is damned amazing, as the 7070 was a VERY ambitious 
machine. 30,000 transistors, 22,000 diodes on 14,000 circuit 
cards.  TOTALLY mind boggling.

And, the 7074 was a serious computer, given the vintage.  
Either 4 or 6 us core cycle time was QUITE good in 1961 or 
so.  10 us instruction execution time was pretty decent.
