I added a half-height Seagate ST238R to my Z159, along with the ST11R RLL 
controller that I bought as a package from First Capitol Computer in Missouri.
The Seagate fits right underneath my two 360K floppies, and I haven't had
any heat-related or other troubles in 2.5 years.  As I recall (my notes are
at home), there was a metal bracket that needed to be snapped off so that
the drive could fit underneath.  It was all detailed in the docs sent by
First Capitol.

>-  Finally, I would like to upgrade the floppy drives to 1.44 M microfloppies in the near future.  Zenith has given me three different opinions about the upgrade  a)  "If the monitor ROM is right (ie the right version?) no problem"

(omissions again)
As I understand it, you *may* need a ROM upgrade as well.  If your current
ROM supports the 101-key keyboard, then I believe it can speak to 1.44 M
floppies.  Then you need a controller that can handle them; it's very
unlikely that the stock Z158 controller could do it, since the Z158
predates 3.5 inch floppies by a year or two.  I pondered this upgrade as
well, but then just bought a Z248/12 from the HUG Bargain Center, and got
*everything* upgraded at once!
