BUTTONS
CAS CLR — Clear the virtual cassette buffers
CAS IN — Load VIBEDRONE.DAT into cassette read buffer (use with IN#3)
CAS OUT — Download cassette write buffer as VIBEDRONE.DAT (use with OUT#3)
FULLSCREEN — Toggle fullscreen mode (Escape to exit)

GT — Speed: 2MHz (vintage) → 3.375MHz (Premium) → 6.75MHz (turbo)
VDU 100% — Toggle VDU cycle-stealing (60% CPU — matches real hardware speed)
HELP — Show this help
KBD — Open on-screen keyboard (mobile/Android — types into READY/EDIT)
LOAD — Load .mwb tokenised / .bas text / .txt file / .bee machine code (auto-RUNM)
.bee: load address auto-detected (loader header / self-reference scan /
default 2304). Runs immediately — RUNM "file"xxxx equivalent. Status bar
shows the detected address. If a BASIC program is running you will be
asked to stop it first (same as loading a new BASIC program).
PASTE — Paste clipboard text as keyboard input
PAUSE — Freeze / resume emulation
RESET — Cold start — resets CPU and restarts BASIC 5.29e
WARM — Warm reboot — preserves your BASIC program and video state, returns to
Ready (same as a real Microbee's warm restart)
SAVE — Save current BASIC program as .mwb file
KNOWN QUIRK
Blank lines during LOAD — some .mwb files carry trailing-space padding
in individual lines (leftover from in-place edits on original hardware).
These wrap onto a blank-looking second row at 64 columns. Safe to
ignore — the program itself is unaffected.
EDIT KEYS
Ctrl+S / Backspace / Left arrow — cursor left
Ctrl+D / Right arrow — cursor right
Ctrl+F / Shift+Right arrow — word right
DEL — delete char at cursor
Ctrl+C / Break — abort edit / stop LIST
BASIC SOUND

OUT 2,65 — speaker ON (bit 6 high)
OUT 2,59 — speaker OFF (bit 6 low)
LPRINT — send output to virtual printer (download with PRINT button)
