     Since Zenith introduced these different CTL-ALT-x sequences into all of
its computers, they must have had something special in mind with the very
first ones that supported only CGA.  I have a Z-151 with a CGA, and the three
sequences mentioned above do the following:

i = half-screen interlaced mode (half size)
f = full-screen interlaced mode (full size)
n = return to normal, non-interlaced screen

As a side note, both interlaced screens give me a headache on my monitor.  I
think that a long-persistence phosphor is required to make the screen
viewable.  Perhaps this was all another one of Zenith's innovations before they
succumbed to producing only IBM style PCs.
