Is there a 3B1 StarLAN and tape backup unit "clash"?

offers some 3B1 items for sale, and in the notice appears:

	"... One 3B1 STARLAN card is modified so it doesn't clash with
	tape backup unit, second one is not.

Interesting.  I've been using tape backup and StarLAN and haven't experienced
any problems.  Is the modification required for only certain ``REV.'' levels,
or is there something insidious that will jump out and bite some day?

What is the actual modification?  It's my recollection that nothing of this
nature has been discussed in this newsgroup during the past several years.
