The museum had some very, very early computing devices. You know, the stuff that filled a room and had something like 16K of memory. These things could even process thousands of instructions per section. 
A lot of those early computing days centered on the military. They even had a German Enigma Machine.

The S/360 project leader also brought us an important book way back then whose message is just as important relevant today. How did it go? Something about nine women not being able to have a baby in one month?

Speaking of Big Blue, a bit later on the tour was a machine that I was lucky enough to work on during my co-op days at IBM; the mighty RISC 6000. AIX was my first real experience with Unix and I fell in love with it. The (then) giant 24" CRT monitors were pretty cool, too.

The very end of the tour focused on more recently recent advancements such as cell phones, the commercialized Internet, and even iPods, but I truly enjoyed the computers of my youth. Sure, there were some Apples (II's, Lisas, and of course Macs), but would could ever forget the Trash 80's, my beloved TRS-80 line.

There was also a fun set of exhibits focused on early video gaming. They had my personal favorite system; the Atari 2600. Notice this one is a 4-switcher with "real" simulated wood-grain.
This makes me want to dig out my old 2600 console and plug in classics like Yars Revenge and Pitfall and play like I was 14 again. Of course, my son is 14 now and he was NOT impressed the last time I pulled it out this game system to show him. The video games today are truly awesome, but nothing can replace my memories of growing up on this machine in the 1980's.
