PCalc turns 25

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.

Such an incredible run for James Thomson. Congrats!

    I’ve always loved PCalc. It’s my go-to calc app almost every day. As a CG artist, I use it constantly for conversions between metric and “normal” units of length measure. And there’s the frequent ratio to percent calcs for scaling things.

    James’ video presentation was educational and entertaining. Love his Scottish accent and dry Scottish wit!
