Err, yes... Hence my feeling that swapping boards, unless you have a very
good idea that they are compatible, is a very bad idea. I've actually had
to sort out machines where some idiot has swapped boards for totally
incoompatible ones (i.e. swapping an RQDX1 with an RQDX3) and not
bothering to tell me. After I've found the real fault (in the
aforementioned machine it was stiction between the hard disk heads and
platters), I then have to figure out just what else has been done.
