The 10^-15 figure is ridiculous, and a 7090 with 12 tape drives would have had to have at least two channels, so they claim that you could read two tapes at the same time is also ridiculous.
Yes, the 7090 was painfully limited and slow by contemporary standards, but there's no need to exaggerate. -- Shmuel (Seymour J.)
