ADDING OPTIONS
A number of options can be added to your MultiRam RGB card. An RGB
monitor can be used by the card, additional memory cards can be added to the
back of (//e RGB card, and a 16-bit 65C816 processor can be attached to
address all memory on (//e card. Following are instructions for attaching these
options to the card.
RGB Video
With the MultiRam RGB card in the Apple //e, you may display video
through a National Television Standards Committee (NTSC) composite color
or monochrome monitor or a Red, Green, Blue (RGB) monitor, or to both at
the same time. The RGB output of MultiRam improves the quality of both
color and text displays by removing the extraneous colors that occur during
color transitions in the Appleās hi-res graphics and mixed modes.
To display video on a monochrome or color composite monitor, simply attach
the monitor to the video connector on the back of the Apple //e as you
normally would. To display video on an RGB monitor, you will need to
attach a cable to the MultiRam RGB card to connect the card to the monitor.
Figure 2.2 shows the signals that are present on each pin.
You may purchase an RGB connector cable from your dealer or from
Checkmate Technology. The RGB cable was not packaged with the
MultiRam card as it would have been an unnecessary added expense for those
without an RGB monitor. Also there are two different cables for the
MultiRam RGB, one supports the Apple type TTL, RGB monitor and the
other supports the IBM TTL RGB type monitor. Read Chapter 6 - Hardware
and Software Compatibility to decide which cable is needed for your monitor.
