If a color monitor is all you have, however, you will not be doing yourself a favor by purchasing one of these emulators. I know this too well from my own experience. The half-screen mode is too awkward to use. Manipulation of screen objects becomes much too difficult. It is particularly disconcerting to "lose" the mouse pointer on the other half of the screen. The full-screen mode is also very difficult to deal with. In this mode, half the resolution is lost, which hinders reading text. "Hinders?" Well, come to think of it, it's painful to try . . . . Any advantages of having the two screen modes available at the touch of a key are negated by the loss of speed due to the remapping of the screen. That 20% speed advantage over a Mac evaporates as soon as you start up with a color monitor. The effective speed is probably less than a Mac with the Sac running on a color monitor. If you really want to see what I'm talking about, send me $150 and I'll send you my Sac w/ROMS. 8-) (Actually, I do want to sell it, but you don't want it if you don't have a monochrome monitor.) -- Jared J.
