Description
Description
## This is a project still under development.
The firmware needs to be written and the hardware connections need to be debugged.
The following is the public GitHub repository where I am developing the firmware:
[acorn\_bbc\_master\_compact\_expansion\_cartridge](https://github.com/DanCasterIt/acorn_bbc_master_compact_expansion_cartridge)
