- You are currect, that in theory differential SCSI doesn't add
- speed. In HP's case, however, the *card* is faster, according to
- HP specs. I guess the internal card is kept inexpensive, while the
- add-on EISA card is a full-out performance beastie :-)

- Why can't you get a non-differential SCSI card for EISA?
