I'm obtained an Owner's Guide. Specs from back surprised me a little. I expected worse. 14" diagonal 0.52mm slot pitch high contrast black matrix 50-75 watt power draw scanning freqs 15.734khz / 60hz bandwidth text ntsc 8.0mhz bandwidth graphics ntsc 3.0mhz composite sync negative 1.0 +-0.5 volts Vpp / 75 ohm. From all this, I calculate roughly 512 vertical slots, or "dots" horizontal rez... or approx 192 TV Lines resolution ;-) That's exceptionally good for a 14" crt back then, and explains why it can display 80 char text in b/w no problem.
Although it certainly doesn't hurt to have a fine shadow mask pitch, 0.52mm is really not very fine. The CRT was chosen to support just enough resolution that it's tolerable to view 80-column text on it. It's pretty good for a TV CRT, but not very good for a color monitor. What makes this monitor unique among composite monitors, and able to display readable 80-column text at all, is that it has a switchable bandwidth luminance channel that goes into high bandwidth mode when in monochrome mode. -michael NadaPong: Network game demo for Apple II computers!
