one last comment....learning here, did not know the connection between
cyber 70 and the 6600. Thanks
It's a bit confusing if you don't know the CDC model numbering.
The 6000 series (of which the 6600 is the first) was also called the Cyber 70 seriess.
Except that the Cyber 76 is another name for the 7600, which is vaguely like the 6000
series but not compatible. All those machines are first generation, discrete transistor
machines.
The next series is the Cyber 170 series, IC based designs, compatible with the 6000 series
but faster. Once again, there's an oddball, the Cyber 176 which is a successor to the
76, in other words a 7000 series machine.
So you'd find CDC 6000 series documentation under Cyber 70, and also generic stuff
that carried across to later machines -- like I/O channel specifications.
