http://web.mit.edu/6.933/www/Fall2000/infocom/csdemo/index.h... has screenshots and a downloadable copy of the 'infamous' Cornerstone database that Infocom built.

It looks quality for the era it was built in.

I picked up Cornerstone at a going-out-of-business computer store in 2000 or so. They had probably had it on the shelf for 15 years.
