Yes, from an era, when economy in programming was a virtue.
It still is a virtue with the ascendency of the iPhone, iPad, and
other mobile platforms.
Speaking of which, Apple donated the source code of MacPaint and
the QuickDraw toolbox to the Computer Museum, who have made it
available to all.
The main source file for MacPaint is 157K; about 5000 lines of Pascal.

Well worth the perusal, if only for a good example of how code
*should* be written, clear, structured and understandable.
There's a quote from Bill Atkinson in the article:
"[Bill] later said about software in general, "It's an art form,
like any other art form... I would spend time rewriting whole
sections of code to make them more cleanly organized, more clear.
I'm a firm believer that the best way to prevent bugs is to make it
so that you can read through the code and understand exactly what
it's doing… And maybe that was a little bit counter to what I ran
into when I first came to Apple... If you want to get it smooth,
you've got to rewrite it from scratch at least five times.""
Words of wisdom...
The faster machines become along with huge amounts of RAM, the
sloppier code gets.
I remember my first computer, a Commodore 64 would run a full
featured flight simulator with only 41K available RAM.
