#3024 — Source code for Photoshop 1.0

Adobe Photoshop Source Code

- With the permission of Adobe Systems Inc., the Computer History Museum is 
pleased to make available, for non-commercial use, the source code to the 
1990 version 1.0.1 of Photoshop. All the code is here with the exception of 
the MacApp applications library that was licensed from Apple. There are 179 
files in the zipped folder, comprising about 128,000 lines of mostly 
uncommented but well-structured code. By line count, about 75% of the code 
is in Pascal, about 15% is in 68000 assembler language, and the rest is data 
of various sorts. To download the code you must agree to the terms of the 
license.


So, Photoshop was originally developed primarily in Pascal.  Who knew?

Wow, that's actually pretty interesting.  The break-down into 75% Pascal 
and 15% assembler by lines-of-code makes me wonder about the breakdown 
by functionality, rather than LOC.

23 year old source-code.  I wonder how many man-hours it would take to 
create a functionally-equivalent program using today's modern 
technology, and techniques, and freely available libraries.  I'd imagine 
a lot of the image loading/saving/modifying code is available 
out-of-the-box in many libraries these days.

It would be an interesting benchmark to see if software development has 
actually improved over the years, or if we're just doing the same things 
differently.

In addition to that, in many cases a lot of the code in non-trivial
applications deals with handling classic data structures, maps, linked
lists, tables, etc.
All that is already provided in contemporary languages + libs.

You sound surprised (that anything useful can be written in Pascal).

Although it does seem to have a few extensions by the look of it.
