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.
