Mental-1, a Brainfuck CPU

MENTAL-1 is a minimalist CPU designed to run Brainfuck, a simple programming language with only eight commands. Created by Trey Keown, this project utilizes 7400 series components for its construction, excluding RAM and ROM. The CPU operates at a stable frequency of 3MHz and features peripherals such as a PS/2 keyboard interface and a 40x2 character display. The project aims to educate others about CPU design and digital logic, demonstrated through hands-on activities at Maker Faires. Keown has completed the MENTAL-1 design and is now working on MENTAL-2, which promises to be more compact, as well as an FPGA implementation. The project has garnered significant interest, with a community of followers and discussions surrounding its development.
