a Quadram board, so the problem may be a design flaw in the new Quadram
384k board, rather than a pc problem.  (The noise comes from the speaker
and is probably due to spiking on the power buss. If the CPU is in a 
very tight loop it's a barely audible continuous high frequency pitch
which is annoying, and if it is listing to the screen it comes out as clicks.
Beware that subliminal high frequency noises can cause significant discomfort
so you folks in noisy environments should make sure your pc is not making
such noises.)
	I called Quadram and they finally admitted that it might be a board
problem and to send it in.  I'm now worried that that it's a design flaw
and I'll get the problem right back.
	While we're on the subject of Quadram and all those other all in one
pc boards, here are my experiences with my 384k board (also includes clock,
serial port, parallel port, and some software):
	(1) Their customer service people are bozos;
	(2) the serial and parallel ports work but fail the IBM diagnostics
	    routines (apparently because of circuitry differences.  I don't
	    like that, because who knows when the incompatibility will show
	    up. This gave me quite a heart ache.
	(3) Their "software" doesn't seem to work properly. For example,
	    the print spooler occasionally drives the printer crazy or
	    simply hangs the system. It also won't work in Basic.
	    If you have any other device drivers like the ansi.sys or
	    printer device drivers included with dos 2.1, then forget it.
	    You can't do a system reset and the system behaves weird
	    occasionally (even when the Quaddriver is loaded first as
	    Quadram says).
	(4) which brings us back to (1), customer service. You explain a 
	    problem and they say they will call back, but never do. This
	    has happened six out of six times. There is a possibility that
	    they are doing this systematically to minimize returns and
	    overhead.
Anyway, are other Quadram people experiencing the same problem? How about
you Tecmar and AST et al. folks? Do you have similar problems? What is the
best add on board?
