From Actor to the Real Thing

I decided that I needed more information about the Actor programming language. While at The Bit Bucket one day I asked Laird if he could get me some literature about Actor, figuring the store could place an order for me. He gladly accepted my request.

A few weeks later Laird had the materials in hand and he presented them to me. Then he said something that would completely change everything. He asked me, "Why don't you have a look at Smalltalk?" He told me that Smalltalk was the real deal.

This was not the first time I had heard of Smalltalk. At the New England Mobile Book Fair I had seen a book about it. I ran back to my office and started digging through issues of BYTE until I found an ad for something called Smalltalk/V.

I had seen this sort of ad before, but I just skimmed over it thinking it was a kind of communications program of the sort used with modems. There was at this time a very popular application of this kind named Crosstalk XVI, and this was the source of my confusion.

The ad seemed very interesting. I began to research Smalltalk. I learned that there was an August 1981 issue of BYTE dedicated to exploring Smalltalk. I went to the Boston Public Library and xeroxed all the articles from that issue. It cost me about $40 to do this. So I began to educate myself about Smalltalk.

Books I didn't buy

Before there were big book stores like Borders or Barnes & Noble there was The New England Mobile book fair in Newton. This could hardly be considered walking distance from my home growing up in Needham, but I had made the trip on foot a couple of times as a kid with my brother Ernie. Now I made the trip more frequently since I had a car.

This store was really just a big warehouse, poorly lit, and not very well organized. However this was the largest collection of books for sale to be had for miles.

I remember clearly two books that I browsed there that I didn't buy but which left an impression on me.

One was called A Small C Compiler, by James Hendrix. Not the famous musician, of course. ;-) I read just enough of the book to appreciate its biggest idea. Once you write enough of a C compiler in assembly language, you can use that C compiler to write itself! Like I said I didn't buy the book, but I learned important ideas from just browsing through it.

Another book was call Smalltalk-80: The Language and Its Implementation. This was a tan and blue hardcover. I can't say I really understood at that time what I was looking at, but it was interesting enough that I didn't forget it. In more recent years I did find a copy of it used and now am a proud owner. Smalltalk is a terrific language this book explains in wonderful detail how it works. Nowadays the entire contents of this book can be read for free online.
