Here's a peek at the in-progress kernel API for Sentinel 65X. It's loosely based on that of CP/M and MSX-DOS 2.

Each call is done by loading the C/X/Y registers as listed, and using the COP software interrupt to trigger the kernel call. This means that the actual address of a given kernel call might change version to version, the ABI will remain stable.
