Interesting. I wonder why I lose characters when I type during disk access, then? I do not recall that ever being the case with KenTon or SuperIDE. It's not as bad as with floppy access, but it still happens. (Yes, using the hard drive mode for 128MB images.)

Yes. Close enough now to not care (but then, many also find Drivewire bitbanger speeds to be close enough now). But, back in the day, we'd switch to a new interface just to save a few seconds on megaread ;-)
