Re: The Seymour Cray Era of Supercomputers

According to Michael S  <already5chosen@yahoo.com>:

Sorry, I did not read Wikipedia articles about /50 and /65 with
sufficient attention and confused announcement with shipment. Didn't
realize that for /50 the time between announcement and shipment was
much longer than for /65. 

 
With that correction, only three months which doesn't seem like much.
The physical planning for power and cooling and raised floors and
such to be ready for delivery would take longer than that.

According to Wikipedia:
Model Announcement Shipment A-to-S
50    1964-04      1965-08  18 months
65    1965-04      1965-11   7 months

The original 360 announcement included the model 60 which was replaced by the 65
which had faster memory. I believe that all of the 60 orders were converted to
65 orders. According to Pugh et. al., the 65 shipped ahead of schedule, sooner
than the 60 was supposed to.
