Here's a poser: On the Zenith-248 (at least, that's what I tried it on), I found by sheer accident that Ctrl-Alt-F does very nasty things to the video mode while text is on the screen. Does anyone have any idea what the combination of keys is actually doing? The letter "F" brings several not-so-technical phrases to mind, but I doubt that this was Zenith's intention. ------------------------------------------------------------------------------ Neal Miller | "Why not go mad?" | millernw@clutx.clarkson.edu Clarkson University | - Ford Prefect | millernw@clutx.bitnet ------------------------------------------------------------------------------

Pressing Ctrl-Alt-F on my Heath-148 in text mode seems to vibrate the characters up and down very rapidly; if it weren't for the terrible flicker, this would effectively fill in the thin lines between pixel rows. My guess is that F means 'fill'. (Incidently, Ctrl-Alt-N changes the video mode back to normal.)

Well, a little while ago we were discussing such things. There are three such combinations that appear to do things to the screen. On some machines ctl-atl-i throws the display into interlaced mode, on my SupersPort it simply blanks the LCD (I haven't tried it with an external CRT) ctl-atl-f and ctl-alt-n both return my LCD to normal operation, they appear to do similar things on other Zeniths. i = Interlaced, n = normal, f = ???

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 | | -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
