In mid-November, 2019 I once again got a bird's eye view of Boston's Logan airport as I headed for SEMICON Europa in Munich, Germany. The main purpose of the trip was attending SEMICON Europa, a major semiconductor industry trade show. As part of the show, I organized and chaired the "Smart Design" session, including talks and a panel session on current chip design issues. After the close of the show, the SEMI staff in attendance at the show got together for a post-show dinner.
After the close of the show early Friday afternoon, a friend and I went to the BMW Museum. They had an interesting exhibit of historical and concept BMW vehicles and engines. I didn't take many photos, but here are a few.
Another German friend joined me in Munich for the weekend to do a little sightseeing. She's a big fan of zoos, so we went to Tierpark Hellabrunn (Munich Zoo) on Saturday. It was a bit chilly and cloudy, but it wasn't raining (or snowing). We both took quite a few photos, and some video. The zoo has quite a few species that were either near extinction, or were extinct but through cross breeding have been restored.
- European Elk.
- Tarpan. These wild horses became extinct in the 19th century. The tarpans here are bred-back from other horses, producing a look-alike.
- Auroch. First domesticated around 6500 years ago in the middle east, the auroch is the ancestor of many of today’s domestic cattle species. This is actually called a bred-back auroch, since the original species is extinct. These were bred back in the 1930s by selectively breeding domestic cattle.
- Vicuña. The smallest member of the camel family.
- Red River Hog.This hog was very interested in the sound of the camera. Each time I took a shot, it raised it’s head a litle more, looking directly at the camera. Thanks for posing!
- Persian Fallow Deer.
- Polar bear. (Check out the video!)
The polar bear was very busy pulling apart a plastic barrel stuck on a tree branch near the stream in it's habitat. (48 second video.)
We decided on an indoor activity on Sunday, so we went to the Deutsches Museum. We visited a few of the technology exhibits (there were too many to see all in one day). One of the most popular exhibits is the high-voltage demonstration. Other energy related exhibits (among many) included the steam powered portable generator and a scale model of a windmill, showing the inside structure.
Of course, we had to visit the computing and semiconductor exhibits. It brought back lots of memories (no pun intended).
- I had to include a slide rule, the first computing device I used in college.
- An early non-volatile memory, made from small magnetic cores. I still have one of these in my collection. It's 4k bits, or 512bytes.
- An early home computer, the Sinclair ZX81, ca. 1981. I still have one of these as well, purchased when they first came out in 1981!
- Some old-timers might remember saving and transporting files on a tape drive.
- Next is a plot of the layout of a chip using a standard cell layout methodology.
- Last is a stack of diffusion furnaces, used in the manufacture of the chips.
