basically yes.

I gave up on the 9000 sampler because it was very difficult to sample anything with the quality of the best voices on the keyboard, and therefore you just used it for comic effects, putting your own voice in a count down, one, two, one, two, three, four etc. that type of thing. When you'd done that a few times you never used it again much. Others may have more use for the sampler for comic effects on stage etc.

The scsi was really for a zip drive, in the days when they were cheaper than a hard disk solution. Now it is pretty much out of date because hard drives are cheap and much better than a zip, and no-one will be making scsi stuff much in the future anyway.
