Did you know..? (MSX trivia!)

Ah, great post!
Finally I can share the dancing mouse in Sony´s HiBrid:
Connect the RL mouse to port 2 and press the second trigger while start up the programm will present you a dancing mouse. Press the first trigger to see the mouse bow to you.

I myself have never seen that, but SONY HB-F1...I don't know whether that is an specified model or common within F1 series ...has an easter egg. I can't find any mention to this topic on MRC wiki.

The word is that HB-F1 speaks "it's a SONY" by PSG sampling when they keep pushing two keys while booting. I don't clearly remember these two keys... probably "F" and "1", or "H" and "B". Wish somebody to upload the video replay...

Excuse me, my lack of exactness. Honestly, I wondered that was just a kind of urban legend. Anyhow, not a few Japanese MSXers mentions about that on the web, however, any writing is also inexactness. :-P

It´s true!
I don´t know which keys exactly, but if I cover the left part of the keyboard (what I can do with one hand), there appears a "making of"-roll an at least you can hear "It´s a Sony!"
Amazing!

There is also easter egg in the MSX-DOS1.... To see it, you need to input 127 or 255 characters, then press CTRL-J and after that press backspace or LEFT.
