Be aware this hack does not make the drive completely invisible. Many
fastloaders (speeders) will not work with the other lines still connected.

When I made a switchbox, I had to switch all 3 main lines to make it
compatible (DATA, ATN, and CLOCK).  Leaving SRQ connected might be a
problem also, but I'm not generally a 128 guy.
