Re: Monocrome monitor on a IIe or IIc

Hello Paul,

I've found this information about the Apple monochrome Monitor
(A2M6016) in the Apple Til:

I. Technical Specifications
A. Picture Tube:
-- 12-inch diagonal
-- Phosphor EIA Type: P4 (White)
-- High contrast
-- When used with Apple IIGS applications that generate
color, it displays up to 16 shades of gray.
-- Anti-glare
-- Text display: 80 columns by 24 lines
B. Input Signal:
-- Composite synchronous negative 1.0 +/- 0.5 volts peak to peak,
internally terminated with 75 ohm resistor.
C. Scanning Frequencies:
System: NTSC/60 NTSC/50-PAL/50
1. Horizontal: 15.734 kHz 15.659 kHz
2. Vertical: 60 Hz 50Hz
D. Video Bandwidth:
-- Less than 3 DB down at 12 MHz.
E. Resolution:
1. Apple IIGS: 640 horizontal by 200 vertical pixels
2. Apple IIc: 560 horizontal by 192 vertical pixels

III. System Configuration
-- Apple IIGS
-- Apple IIc

Does that make a difference regarding your statement?
I just wonder why the Apple IIe isn't mentioned.

Thanks
Carlo
