EHB exceeds this by allowing 32 colors out of 4096 plus their half-bright counterparts ( 32 + 32 out of 4096 ), at 320x200 to 360x576, on a standard composite-video or video-frequency RGB monitor.

Launched in 1981 by London-based Rainbow Software ( now Showcase Presentations Ltd ) and running on Apple II computers with just 16k of RAM it was the first commercial computer-based presentation system displaying directly onto RGB monitors or projectors.

Most LCs were purchased with an Apple 12 " RGB monitor which had a fixed resolution of 512?84 pixels and a form factor exactly matching the width of the LC chassis, giving the two together a near all-in-one appearance.

New features included 128 KB RAM, three-channel audio via the AY-3-8912 chip, MIDI compatibility, an RS-232 serial port, an RGB monitor port, 32 KB of ROM including an improved BASIC editor, and an external keypad.

The BBC Micro and Acorn Electron used a 270?7-pin variety, using 2 pins for control of the Audio Cassette tape player motor; this family of computers also used a 6-pin DIN for RGB monitor connection, and a 5-pin DIN for the RS423 serial port.

The "'Linux Kit "'for PlayStation 2 was released in 2002 and included the PlayStation 2 Linux software, keyboard, mouse, VGA adapter ( which requires an RGB monitor with sync-on-green ), Network Adaptor ( Ethernet only ) and a 40 GB hard disk drive.

On a CoCo 3 with an analog RGB monitor, the black and white dot patterns do not artifact; to see them one would have to use a TV or composite monitor, or patch the games to use the hardware 128?92 four color mode in which the GIME chip allows the color choices to be mapped.

The arrangement of the items on screen doesn't matter, but the connections do : a numerical constant box could be connected to a mathematical function; connected to a graph, which would display a horizontal line; input as a color value on an RGB monitor; or even used to trigger a sound effect.

Another early addition ( after about 6 months ) was an RF Modulator that allows the machine to be hooked to a color TV when run in its low or medium resolution ( 525 / 625 line 60 / 50 Hz interlace, even on RGB monitors ) modes, greatly enhancing the machine's saleability and perceived value ( no need to buy a prohibitively expensive, even if exceptionally crisp and clear, monitor ).

That said, the obvious solution is for the manufacturer to have blue colors in an RGB monitor that look blue but contain as little higher-frequency light as possible, i . e . are sharp blue, and so long as that's what he does, the only other tip is not to have your monitor really really bright lest you be at somewhat elevated risk for macular degeneration someday . talk ) 20 : 40, 21 January 2015 ( UTC)
