## Emulator ## Emulator
The pat80 memory monitor (the os) can be run in a z80 emulator. This repository contains an emulator as submodule, already set up to run the os. The pat80 memory monitor (the os) can be run in a z80 emulator. You can find a very simple one I wrote ad hoc in `pat80-emulator`. It's based (and depends on) the excellent [Z80 emulator library by redcode](https://github.com/redcode/Z80). Follow the instructions on `pat80-emulator/README.md` to build and run it.
To try it, head to `pat80-computer/software/z80-assembly/os/` and run `make run` to build the rom from assembly and start the emulator. You will see some windows showing the emulated computer's memory and register status and the pat80 memory monitor prompt. The emulator requires a rom file to run. To obtain a pat80 rom, head to `pat80-computer/software/z80-assembly/os/` and run `make run` to build the rom from assembly and start the emulator. You will see some windows showing the emulated computer's memory and register status and the pat80 memory monitor prompt.
