A DOS utility, sized about 25Kb, was offered by Gateway for saving and uploading AnyKey key mappings and macros, named “anykey.exe” or “anykey34.exe,” and may still be found by searching the Internet. It offers three functions: Saving key mappings and settings from keyboard nonvolatile memory to a file, uploading settings from the file to the keyboard’s nonvolatile memory, and checking the file’s integrity. It must run in DOS, and it may require the keyboard be connected through a PS/2 or AT-style 5-pin-DIN socket, though a PS/2<—>USB adapter seems to work well for normal keyboard usage.
