Community Memory: Discussion List on the History of Cyberspace ______________________________________________________________________
John Agar asks "Anyone know what the 'drop in performance' (of the Stretch) was?"
I think the reference may be to the fact that IBM touted the Stretch to be a sub microsecond machine (cycle time) and IBM couldn't ultimately produce this speed. This is a bit out of my area, but I remember the event--can't recall having read about it anywhere but there must be a source somewhere. Maybe Bell and Newell.
"Atlas/Titan. Was the Titan the Atlas II?"
When I first saw this question I thought the author may be mixing up the computer with the ICBM sequence, in which the Atlas missile was followed by the Titan. Can't say the Titan replaced the Atlas, but it was bigger and more expensive. Great rocket, though.
