The MiSTer SAM Coupé core (GPL-2.0-or-later throughout, audited per file) has been imported behind the same platform layer. Three builds in one day: the machine with its ROM and the scaler, then the USB keyboard mapped to the SAM's 9-row matrix, then disk images mounted from the SD card through a WD1793 bridge.

All build-verified with zero timing violations, at 85% of block RAM and almost no setup margin. Nothing has been programmed yet; the first bench load is next. The Raspberry Pi 5 for the debug host also arrived this week.
