I use a DTK 386/25 running UNIX-- with the bus running at 12 mhz.  In it
I have ran:

	Western Digital 1006 hard drive controller (both MFM and RLL)
	Adaptec RLL Hard drive controller.
	CMS MIDI card
	Several internal 2400 baud modems (I've tried three or four)
	Hayes 1200 internal modem.
	Several I/O boards (I've tried about six)
	An (early model) ATI VGA wonder.
	WD8003 Ethernet board
	

I have NEVER found a board that will not run in it.  I dont doubt that 
some older boards will not run in it-- but I dont put old boards in my
new-fangled 386.  If I did ever buy a board that would not work, I'd return
the board.

I have never had any problems running the bus at 12mhz-- and my machine 
has been running 24 hours for the past two years.  I have ran hundreds of
programs on this machine.  Everthing from Flight simulator to Turbo C++ to
Novell Netware 386 to UNIX.  

If you have to use the lame ISA bus-- you might as well use it at 12mhz.
