で、ＦＡ。 Smalltalk（暫定Dynabook環境。通常、ALTO）、Star、Lisa における、互いのルック＆フィールの似かよいの程度や、それぞれの開発時期の重なり具合など、状況証拠的に、おそらくそうじゃないかなーとは思っていましたが、やっと裏がとれました。
BYTE: Do you have a Xerox Star here that you work with?
Tesler: No, we didn’t have one here. We went to the NCC when the Star was announced and looked at it. And in fact it did have an immediate impact. A few months after looking at it we made some changes to our user interface based on ideas that we got from it. For example, the desktop manager we had before was completely different; it didn’t use icons at all, and we never liked it very much. We decided to change ours to the icon base. That was probably the only thing we got from the Star, I think. Most of our Xerox inspiration was Smalltalk rather than Star.A behind-the-scenes look at the development of Apple’s Lisa | Modern Mechanix
