BBC Micro (Master) power-on - boobip!

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!

J'adore ces ordinateurs anglais des annees 80, merci

Those of us who grew up with that sound at primary school in the early 80's got to love it again when it was a well used sample in the acid house scene in the late 80's

This is probably the best video on RUclips

It's definitely up there.

As an American, I'm loving these British computers.

Thanks. You should love the new Acorn Electron one, then! A PiTubeDirect is pretty impressive on them, too: adding a Raspberry Pi co-processor to the BBC or Electron - adds a 300+MHz 6502 or a 1.4GHz ARM7 on your 6502-based machine!

I always wondered why they had two beeps. Did the first one mean "on" and the second one mean "working ok" ? Or did they just decide to use two beeps because it sounded better?

[@lsbyte]

I believe the first one is just the default state of the chip and buses, when the power is applied, so it's not deliberately being generated. The second one is a deliberate ASCII BEL / VDU 7.
