According the  EUROPEAN ACADEMIC HERITAGE NETWORK
...the vast majority of late 20th and early 21st century scientific heritage
will disappear, whether we like it or not.
There is no space, no money and no interest.
Estimates are that 80-95% op post-WWII scientific instruments and equipment
can not be preserved.

One of the reason to keep the calculator heritage alive.

From now on, I'll try to include Large Zooms (XL-pictures) of
representative Scrapbook-pictures (via left-click),
for example: 
Main Page (Scrapbook pics) and Detail Page (of one of the Scrapbook pics)
This feature was in my bucket list for quite a while
but since all data is captured in a Database...
it takes a lot of programming to auto extract html-pages.

The CALCULATE! Expo has closed his doors.
3 months preparation and 3 months Expo-time has passed away.
It has been an interesting experience, unfortunately every item is once again moved to boxes.
It sure would be nice to have any perspective regarding a permanent location in the future.
One can always dream, any ideas always welcome!
