Vacation photos
I've just posted the photos from our 3-week vacation. There are 6 albums with nearly 450 photos. They can be found at http://sugargroup.net/photos/varrin/2009eastusvacation/
Most of the photos are self-explanatory. Some have captions. Some of the people pictures are uncaptioned (if you know who they are then you know who they are).
I have to add one special photo description here which wasn't blogged but was part of an email exchange with my dad. In the Air and Space Museum at Dulles, there was a Control Data 3800 computer. I pointed this out to my dad and he wrote this back:
During the mid-1960s, when I worked for CDC, there were three families of computers built and sold by CDC.
The 1nna family was the small computer family. Often they were packaged to be the size of an office desk. Most of them had 12-bit word length. However, one model had an 8-bit word length and one model had a 13-bit word length.
The 3000 series was the mid-range family. They were packaged the way you saw at the Smithsonian. The 3100 was the bottom of the family and I think ( if I recall correctly ) they had a 24-bit word length. The 3800 was the top of the family with a 48-bit word length ( as the Smithsonian article said ).
The 6000 series was the top of the line. These were the world's most powerful computers when they were first built. They were packaged a bit larger than the 3000 series. This family had 60-bit word length.
Thanks for sending that link and, thus, reviving those old,
delightful memories.
