The DIY Calculator Hardware Project consists of several sub projects:

1. Creating the real hardware: a printed circuit board (PCB) with the processing chips, an LCD module, switches, and connectivity to a host computer
2. Implementing the DIY Calculator CPU together with supporting functional blocks within a programmable logic chip (a so-called "Field Programmable Gate Array" - FPGA).
3. Writing the firmware running on the hardware, including a ROM monitor
4. Adding a software tool for communicating with the hardware (e.g. uploading user programs)

On this page you will find information about the progress of the project as well as technical details.
