I had a UNIX zealot phase back in the 1990's, until the university library opened my eyes to Xerox PARC world, tucked away at the back there were all the manuals and books about Smalltalk from Xerox, eventually I also did some assigments with Smalltalk/V, and found a way to learn about Interlisp and Mesa/Cedar as well.

My graduation project was porting a visualisation framework from Objective-C/NeXTSTEP to Windows.

At the time, my X setup was a mix of AfterStep or windowmaker, depending on the system I was at.
