   No, not yet. I've been having too much fun playing with it. It really
works great! I do intend to open it up and see what kind of drives and
drive controller IC it uses. BTW Grumpy Ol Fred found a message on the net
that said that it used a proprietaty 720k format so I'll try a DSQD disk in
it. 
 
  FWIW I also found message on the net that indicatd that the probes for
these need more capacitance compensation than most probes provide so a
"standard" set of probes may not work perfectly on it. Some brands of
probes and some older Tektronix probes do have adaquete adjustment and do
work fine. Right now I'm using a set of probes from one of my other scopes
and I don't want to mess with their adjustment so I'm just putting up with
the distortion. I'll find an extra set of probes and try to adjust them and
dedicate them to this scope.
