The HP-16C Computer Scientist Calculator was released in 1982. I bought one new, in 1983 and was very impressed by it's function and elegance. This was despite the fact that the device only contained 203 bytes(!) of memory to house both storage registers and programs. In the fall of 2000 I set out to see if I could accurately create an emulation of the HP-16C in software. Although the project got temporarily shelved a few times, I have finally finished an emulator which approaches the original goal.

This calculator is ideal for programmers, engineers and scientists. Unfortunately, this model was discontinued many years ago, but is now available again in software form. This software version has the added advantage of supplying auxiliary views: A scrollable program view that allows viewing all or most of a program in on the screen at once, as well as the ability to watch the operation of a running program; A Stack view that shows the entire state of the stack, Status and Memory usage at once; A scrollable register view that shows the contents of all the storage registers.
