A configuration assumption has been made. + +The two compilers ([used by the z88dk](https://github.com/z88dk/z88dk)) are supported. The sccz80 compiler and the sdcc compiler. The PR is located under Z88dk. + +Background +----------- +This PR is based on running code for the [SC130](https://smallcomputercentral.wordpress.com/sc130-z180-motherboard/)/[SC131](https://smallcomputercentral.wordpress.com/sc131-z180-pocket-computer/) and [YAZ180](https://github.com/feilipu/yaz180) platforms, and is maintained by the z88dk team in this [z88dk-libraries](https://github.com/feilipu/z88dk-libraries/tree/master/freertos) repository. |
