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. ------- -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- | Arnold Gill | | | Queen's University at Kingston | If I hadn't wanted it heard, | | BITNET : gilla@qucdn | I wouldn't have said it. | | X-400 : Arnold.Gill@QueensU.CA | | | INTERNET : gilla@qucdn.queensu.ca | | -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
