] There's a reason why I do this, because I make the connection in the CABLE

] the connector. Remove wire of pin 34 and make a little loop with the piece
] of wire that is still connected to pin 33! Close the connector and put it
] back in place!
For all those people out there that do not get the message: YOU MUST MAKE SURE THAT
YOU CUT THE WIRE BETWEEN THE DRIVE AND THE CONNECTION TO THE GROUND. The whole idea of
this exercise is that you make sure that the MSX always sees a ready signal (it's
negative logic, that's why you have to ground it) on its input. But for the drive,
wire 34 is an output, so you should not connect the output of the drive to the ground.
Just keep it floating in the air. And you need to use this exercise because wire 34
can have at least two different functions depending on the drive model. On old drives
it is the 'Ready' signal. On modern drives it is the 'Disk changed' signal. Most
modern PC bioses are written such that they do not need a ready signal. So it has
become redundant. I guess that's why it has been replaced with a more usefull signal.
