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.
