MIX Builder

MIX Builder is a complete development environment for the hypothetical MIX machine discussed in Donald Knuth's legendary The Art Of Computer Programming series.

MIX Builder is an editor, assembler, simulator, and interactive debugger all rolled into one. It emulates all 157 MIX instructions (including the floating-point operations), and it emulates the card reader, card punch, line printer, typewriter, and paper tape devices.

MIX Builder is a Win32 program. It runs well on Windows 95, 98, and NT4. It may also run in some emulated Win32 environments, but I'm not sure about that.

Binaries

• MIXBuilder.zip - This contains the MIXBuilder executable, docs, and sample code. This is what most people should download.

Source Code

• MIXBuilderSource.zip - This file contains all the Delphi 4 source code for the MIXBuilder project. To build it you'll need to download several other components from my Components page. You'll need to get (at least) TFormSave, TMEditor, TNumEdit, TSortGrid, and TWinSplit.

TAOCP errata and Knuth reward checks

While working on MIX Builder, I was able to find two errors in The Art Of Computer Programming, Volume 1, 3rd Edition.  Dr. Knuth pays $2.56 cents to the first person to find each error in his computer science books, so I'm now the proud owner of two checks from Dr. Knuth.  There's no way I'd ever cash them.  For more on Knuth's checks, see the Wikipedia article Knuth reward check.

• Scan of check and letter about the 2nd error I found.
