I just put Dan Ingall's classic paper "The Smalltalk-76 Programming System: Design and Implementation" from the Fifth Annual ACM Symposium on Principles of Programming Languages, January 1978, online at my site:

My thanks go to Dan and ACM for giving me their permission to publish this -- but especially to Dan since he even went to the trouble to send me scanned images of this paper to work from since I didn't have a copy of it available.
Enjoy.
