# ch81 `ch81` is a Z80 emulator, RC2014 simulator, and ZX81 simulator. It can run ZX81 Basic and achieves the equivalent of a 4.5 MHz Z80 when running on the CH32V006. The core emulator is generated which makes it straight forward to experiment with switch based, threaded, or tail call based architectures. ## Building See .forgejo/workflows/build.yaml. `ch81` builds for Linux and Zephyr.
