HARDWARE & SOFTWARE
COMPATIBILITY
The MultiRam RGB Card’s operation can be enhanced by using other
manufacturer’s hardware and software products along with it. Some of the
more useful products are described in this chapter.
HARDWARE
All hardware products tested with the MultiRam RGB card have been
compatible: modems, mouseR, printer cards and printers, co-processor cards,
hard drives, etc.
The four most useful hardware additions that could be made to increase
MultiRam RGB’s usefulness are an RGB monitor, a large capacity disk drive,
co-processor, and a non-interruptible power supply.
RGB Monitors
To get everyone to the same place, lets cover background so that we agree on
terms.
There are two ways to get color from your Apple //e. The first method is to
use the video jack on the Apple //e motherboard to drive a composite color
monitor. However, this method requires all color and video signals to be sent
over a single wire, which produces OK graphics and poor text display. The
text display tends to bleed colors giving the letters a fuzzy appearance and
making them difficult to read. The second is to use an RGB monitor which
has multiple wires to carry the color and video signals to the RGB monitor.
By using multiple wires~ one for red, one for blue, one for green, one or two
for synchronization and perhaps one for intensity, the video display is much
clearer.
