" MUF — a dialect of FORTH — is one of two programming languages implemented on all MUCKs,
the other being MPI. The speed and efficiency of MUF make MUCKs readily user-extensible: powerful new commands and programs can be soft-coded into the database. Although the only place you'll be able to use it is on MUCKs, MUF is a real programming language: once you've learned it, you can truthfully say you know how to program computers, and concepts and habits of thought you pick up as a Mucker will be useful in learning languages with widespread RL applications.

MUF is an extensible, structured, stack-based, compiled language.

Last week I picked-up a neat single-board computer from the mid-1980's manufactured by Hawthorne Technologies. This SBC is in a 5-1/4" form factor so it could be bolted to a floppy drive. It's based on an 8MHz 68000 CPU and has a dual serial controller, 256k of RAM and a PC-compatible floppy controller. It came with a floppy-based operating system called K-OS and had an assembler, debugger and Forth language. The setup I got came complete with manuals and disks. The disks include a floppy-based operating system, Forth, a 68000 debugger and a text editor.
