Computer History Museum Releases Eudora’s Source Code

Len Shustek (Hacker News):

It’s hard to overstate Eudora’s popularity in the mid-1990s. The April 22, 1996 InfoWorld article announcing the release of Eudora Pro 2.0 called it Qualcomm’s “best-selling product,” and said that “according to International Data Corp. (IDC), Qualcomm claimed 64.7 percent of all e-mail software revenues in 1995.” A later exhibit about Eudora in Qualcomm’s company museum observed that “By 1996 Eudora had 18 million users, making it the world’s most widely used internet email software at the time.”


The discussion with Qualcomm for the release of the Eudora source code by the company’s museum took five years. In the end, they decided not to simply grant a license, but to transfer ownership of the code, the Eudora trademarks, the copyrights, and the Eudora domain names to the Computer History Museum (CHM). The transfer agreement allows us to publish the code under the very liberal BSD open source license, which means that anyone can use it for either personal or commercial purposes.


The Windows version of Eudora is written in C++. The source tree consists of 8,651 files in 565 folders, taking up 458 MB. There are both production (“Eudora71”) and test (“Sandbox”) versions of the code.

The Macintosh version of Eudora is an entirely different code base and is written in C. The source tree consists of 1,433 files in 47 folders, taking up 69.9 MB.

I still miss classic Eudora in a lot of ways.
