4ft4 is a clone of the MCS-4 architecture (4004 CPU, 4001 ROM, 4002 RAM), with a wishbone backdoor interface to the “ROM” and the RAM that enables loading a program for execution and inspecting/modifying the RAM.
This is an integration of 4ft4 into the caravel harness, with the 4ft4 wishbone backdoor interface connected to the caravel management processor.
caravel_user_project and modifications: Apache 2.0. The original caravel_user_project that this is based on is https://github.com/efabless/caravel_user_project.
4ft4: BSD.
