Intel 8080 emulator, modular by design and allow external and easy creation of io/interrupts external handlers.
The library contains the actual emulator. The executable contains two boards: One which emulates just enough of a CP/M to run the tests, and another emulating Space Invaders.
Running space invaders:
i8080 -board space-invaders SPACE-INVADERS.ROM
Running a simple CP/M COM file (only BIOS output supported):
i8080 -board CP/M <COM file>
CMake is used to configure, build and install binaires and documentations, version 3.14 minimum is required:
mkdir -p build && cd build
cmake ../
cmake --build .
The tests are CP/M COM files and can be found here.
Useful documentations are available in the docs directory in the root of the repository:
- 8080 Data Sheet.pdf: Hardware description for the I8080
- 8080 Programmers Manual.pdf: Programmers Manual for the I8080
- CPM 1.4 Manual.pdf: CP/M 1.4 Manual and references
- CPM 2 Manual.pdf: CP/M 2 Manual and references
- PLM Manual.pdf: PL/M Manual and references, also useful for its ABI.
