	I have just attempted to add 256K to my Z-158 as expanded memory.
	I have 640K of system RAM and added the new RAM to bank 3.  
	However, my playing with the dip switches in sw401 have not been at
	all productive.  In particular, #10 on hangs my system with the red
	RAM LED on.  I've adjusted the other switches to represent my 640K
	and that I have EMS installed to no avail.

	Someone out there must have done this.  Zenith's (awful) manuals
	keep referring to the 'EMS Upgrade Option' -- do I (gack) need a
	logic ROM somewhere?  No diags programs came with my original
	setup.  Please respond by Email, I will post if there is sufficient
	interest.  Sketches of correct DIP settings would be appreciated.

				Thanks in advance.
