PCalc Turns 25 »

James Thomson:

25 years sounds like a really long time. A quarter of a century sounds even longer. Yet, that is how long it has been since PCalc 1.0 was released.

I sent an email to the Info-Mac archive moderators that evening, and it turned up on FTP mirror sites around the world a few days later.

It normally travelled on floppy disks. The web did not yet exist.

PCalc was my first ever application. I started writing in the summer of 1992 and it took me around six months to get it into a state where I was happy to show it to the world. Some of that code still runs today, deep at the heart of the machine.

That’s one hell of a run, and PCalc is better than ever today. Congratulations, James.
