The project was started with IceCube2, and the project files are in the subdirectory 'icecube2'. These haven't been updated in a while, but should prove a worthy starting point. I'll endeavour to keep them updated when I can.
The project with the switch of the 6502 CPU from the gate simulated core to a logical simulated core allowed the FOSS yosys and arachne_pr to build the project. Now all you need is icestorm and the Makefile.
To build:
```
make
```
### Features
* UART support using the second serial channel on the breakout board. (CTS support OS willing).
* LED support using onboard LEDs on breakout, additional LEDs added to mine via a [YL-4 board from ebay](https://www.ebay.com.au/itm/4-4-Matrix-Array-Keyboard-16-Key-Switch-Keypad-8-LED-4-Button-Professional-Blue/183044563197).
