Симулятор Sinclair ZX Spectrum 48K с BASIC и загрузкой с кассеты

Build a Mac app that simulates a vintage 48K home computer on a 3D desk. Model the computer with its rubber keyboard of 40 clickable, animated keys that also respond to the real keyboard, a small CRT monitor with optional scanlines and a clean-picture mode, and a cassette player beside it. Boot into a copyright screen and BASIC prompt, with a power-cycle button that clears memory. Implement a BASIC interpreter for numbered programs with variables, loops, calculations, simple graphics and beeper sound. Let the user insert tape files, type the load command, hear loading tones and play a bundled arcade game with original-style graphics and keyboard controls. Allow recording programs to a tape file and reloading them later. Add camera controls, a side panel for the cassette and a caption for each step. Done means the machine boots, runs BASIC and loads and plays the bundled game.
