Sinclair QL

Boots a Sinclair QL on the open-source Minerva QDOS-replacement ROM. The QL shows its F1 (monitor) / F2 (TV) selection screen; the boot script presses F2, dropping you at the SuperBASIC cursor. Type on the physical keyboard, or use the on-screen keyboard on mobile. Open the debugger to read the live 68000 registers and memory, single-step one instruction at a time, and pause/resume — all backed by the sQLux core rebuilt with a debug sampling API.
