The HP-67 Calculator

You can read about the HP-67 calculator on the HP-67 wikipedia page or on the HP-67 page of the unofficial HP museum site.

HP-67 Emulators

I find that one of the best ways to learn about a calculator is to use it. Given that they aren’t made anymore, many people use emulators instead. There are a number of emulators available and most are quite good.

I make two of the emulators. One is a functional equivalent and the other is a microcode emulator. The second one is my favorite because it is a closer match to the real thing; but both are available on this site (see below).

You can run either of my HP-67 emulators for free in any web browser on any computer and, if you “install it”, you can even run it when you’re not connected to the internet.

You can also buy a copy of either emulator for a nominal sum if you’re interested in seeing what’s inside it and how it works, or if you just like to make sure you always have it. See the links for details.

Using the HP-67 Calculator

There are programs available at HP-67 programs.

Articles I’ve written on the calculator can be found at HP-67 articles.

There is a help page for the calculator (and emulators) at HP-67 Help
