This page presents a minimal card developed by University of Applied Sciences of FRIBOURG and inspired by mini FORTH system of this site. The MC68000 and 68681 are replaced by a FPGA integrating a RISC processor core instructions of which are optimized for the FORTH language. Instructions are based on those of F21 realized by the company Ultra Technology.

Here are the photos of the prototype from Switzerland:

Here is the various chapters of this page:

• an historic of the creation of the card (historic),
• the description of the features of the card (specifications),
• the complete electric schematic (architecture and schematic),
• the program of the ROM and the applications (softwares),
• the description of instructions bound at the board (specific instructions),
• a few pictures of the use of the card (use),
• simulation softwares of the card for MAC and PC (graphic mulators).
