I'm selling a great color monitor for the Apple IIc. It plugs into the RCA composite jack behind the Apple IIc (and I think it can be used with the Apple IIe as well). The ColorMonitor IIc physically looks much better than the ColorMonitor IIe (which are roughly $100+ from a brief scan of eBay).
Delivers great color, with hue, brightness, and contrast adjustments (see pictures). Can be switched to monochrome (gray) so that text is easier to read (see pictures).
