Type at the READY prompt — Esc = Break, Backspace = Delete,
Tab = List — or paste a whole BASIC listing (Ctrl+V).
Tape: pick one of the built-in examples, or your own
.gtp / digitized .wav — either resets the
machine, loads it, and RUNs it; Reload repeats that.
Reset gives a fresh machine at READY and forgets the tape.
Monitor: machine-language debugger — breakpoints, stepping,
disassembly; type help at its prompt. Keys go to the
machine unless the prompt has focus.
Record captures SAVEs and downloads them as .gtp
or .wav audio.
State: Save downloads the whole machine as a snapshot file;
Load resumes it exactly — even mid-game, even mid-tape-load.
Sound is the cassette-port speaker trick: the Galaksija had
no sound chip, but games clicked and beeped through the tape output —
plug in the virtual speaker and hear it.
