As the original poster of the query, I;d like to thank everyone who
has suggested reasons for my squeak. However, I've realized that it
is not a disk drive thing (not that I don't have a ST 251 on my
system, the source of much discussion a few weeks ago), but
something in the video system.

I have a mono monitor and Hercules clone card. The squeak is VERY
high pitched - near the limits of audibility, so perhaps as I get
older I won't hear it any more. The squeak only occurs at certain
times using certain pieces of software. For example, I have just
downloaded the JOVE editor, and while this is running and waiting
for me to press a key, the squeak is there permanently. When I
press a key that needs a response, the noise goes away until the
screen is next redrawn.

It sounds like it is coming from the computer box, not the screen,
so I imagine it's the video controller board. I just wondered what
some pieces of software do to write to the screen / read the
keyboard that is different from others, that would cause this
behavior only at specific points in specific programs.
