I'm looking for the test programs and the Tetris game which were factory programmed on one of the memory cartridges supplied with the calculator.
The design of this calculator is obviously based on the Casio FX-700P, but it appears to be an entirely different machine after all. It uses a 16-bit PDP-11 compatible microprocessor along with external RAM, program ROM and LCD controller. Such open architecture makes it an interesting object of hacking.
I’m very grateful to all the people who shared my interests, collaborated in the projects, or helped me to learn new things, especially: Mahmoud Yassine, BLUE, Miyura, Jacques Laporte, Marcus von Cube, Fuse, Xerxes
