LaTeX to RTF convertor that handles equations, figures, and cross-refe
Latex2rtf tries to convert your LaTeX file into a RTF file for opening in Microsoft Word. The general idea is to try and get the things that computers are good at correct: character conversion, graphic conversion, etc. Page layout suffers because control in RTF is pretty pathetic compared to TeX. Consequently, it is likely that manual reformatting will be needed. Translation of bibliographies is pretty good and a wide range of styles are handled, but you must typeset your LaTeX file to create the needed .aux and .bbl files first. Translation of equations used to be excellent: it used to be possible to double-click equations in Word and then edit with MathType. Unfortunately, this conversion in Word has gotten progressively worse over the years (I changed nothing!). Unfortunately, the only solution is to converting to MTEF objects, which is a major rewrite (but would make OpenOffice users much happier.) Volunteers welcome!

multi-platform cross assembler for 6502/6510/65816 cpu
ACME is a free cross assembler released under the GNU GPL. It can produce code for the following processors: 6502, 6510 (including illegal opcodes), 65c02 and 65816. ACME supports the standard assembler stuff like global/local/anonymous labels, offset assembly, conditional assembly and looping assembly. It can include other source files as well as binaries while assembling. Calculations can be done in integer or float mode. Oh, and it is fast.

A Forth compiler with a little difference
4tH is a Forth compiler with a little difference. Instead of the standard Forth engine it features a conventional compiler. 4tH is a very small compiler that can create bytecode, C-embeddable bytecode, standalone executables, but also works fine as a scripting language. It supports about 95% of the ANS Forth CORE wordset and features conditional compilation, pipes, files, assertions, forward declarations, enumerations, structures, suspended execution, recursion, include files, etc. It comes with an RPN calculator, line editor, preprocessor, compiler, decompiler, C-source generator, a virtual machine, and a multitasking environment.
