INTRODUCTION
This section highlights features of the MultiRam™ RGB card that are explored
at length later in the manual.
The MultiRam RGB card is an expandable, extended 80-column memory card
for the Apple //e with Apple or IBM compatible RGB video output.
MultiRam RGB’s memory is expandable on the card from 64K to 1 megabyte.
You may easily expand the card by adding 64K or 256K RAM chips as your
memory needs grow.
There are currently two optional piggyback memory cards that fit onto the
MultiRam RGB. The first is the MultiRam //e card, expandable to 768K,
giving a total memory of 1.75 megabytes in one slot. The second is the
MultiRam Plus card, which is expandable up to 4 megabytes. giving a total of
5 megabytes of memory in one slot. Either one of these cards can be added
without interfering with: any card in slot one.
At the time this card was designed there was an optional feature built in for a
Static RAM pack. The Static RAM port exists on the MultiRam ROB card,
however this feature was never put into production.
The MultiRam RGB card’s video signals can be Sent to a monochrome
monitor or composite color monitor (an NTSC monitor) through the Apple
//e’s own video connector. The RGB card can also be connected to any Apple
compatible TTL RGB monitor (Red, Green, Blue) through MultiRam’s RGB
connector. Both a standard NTSC monitor and an RGB monitor can be
connected at the same time. IBM compatible monitors can also be used with
an optional Apple RGB to IBM RGB converter cable which is available from
Checkmate.
RGB video produces sharper displays by removing the extraneous colors that
occur during color transitions in high resolution graphics screens and mixed
mode screens showing both graphics and text. Further, using an RGB
monitor, not only are double hi-res displays of 560x192 pixels in
