Power on of my BBC Master with a Retroclinic BBC Master MultiOS selector - includes MOS 1.20 (Model B), 2.00 (Model B+), 3.20 (Master initial version), 3.50 (Master final version) and 3.50 with a TUBE 6502 (actually a PiTubeDirect in the internal coprocessor slot).
Features the infamous "boobip" startup noise!
