I just bought an ASDG 8M/2 board (8Mb board w/ 2 Mb installed), and a
Mini-Rack C.  Sometimes, the board chirps (for lack of a better word)
when it is accessed.  For example, when I hold down the "more" gadget
in Facc, it chirps in time with the increasing number of buffers.
When I run something out of VD0:, it chirps (slightly differently).
The loudest noise I have heard is while the "executing out of fast
ram" part of ASDG's memory test is running.  It sounds vaguely like a
cricket in the distance.

The board has worked fine (for the three days that I have had it).
As long as nothing is broken, I don't mind the noise.  However, I was
under the impression that memory boards have neither moving parts nor
anything else that makes noise (except RF noise, of course).

Incidentally, I (temporarily) have two 8M/2 boards in the rack, and it
doesn't seem like the other one chirps.  Mine chirped even before the
other one was installed.

Any answers?  (Perry?)
