Ein IMS G171 sollte doch der Standard und Ur RamDAC sein. Alle neueren sollten dazu doch kompatibel sein. Gibt es auf alten VGA Karten mit 35Mhz und 50Mhz ...
Im Netz findet man nichts ausser ...
MatScreen M110/120
Monochrome - Large Screen Systems
* Suitable for all ATARI Mega ST computers
* Display area 5 times greater than that of SMl24. Particularly
suitable therefore for CAD, DTP, word processing and spreadsheets.
* All systems use the same controller guaranteeing full compatibility
amongst themselves.
* The system excels through its most simple installation. Without
change to the Mega ST the controller is plugged into the internal bus.
* Two systems are available in the standard size of 19" (M110 & M110L).
The chief difference is in the anti-reflection technique. The OCLI
layer of the M110 permits a stronger display contrast.
* The system can work with or without the SM124. In dual-mode the
system can work with the large screen and the SM124 simultaneously.
* Fast dual-ported SRAMs (256 kbyte) allow access to the screen memory.
This allows bit-block transfers between main memory and screen memory.
* All systems can be extended with the C27 option. An additional 14"'
multisync monitor allows an image of 640 x 480, 66Hz non-interlaced
with a choice of 16 from 262,144 colours to be displayed. The GEM
driver is usable from TOS 1.4 upwards.
* Available optionally with the floating-point Coprocessor MC68881,
16MH.
* The use of the graphic processor ACRTC 63484 from Hitachi is unique.
Used to its fullest it is responsible for:
fast picture construction
background construction of second pictures
SM124 emulation mode (zoom): With a resolution of 640 x 400 the
whole screen area is used. The enlarged display is ideal for
training, demonstrations, and helping those with sight
difficulties. In this mode almost all software is executable.
* All GEM programs are executable with the resolution 1280 x 960. For
years the MatScreen systems have been used for professional CAD, DTP
and word processing.
* Two GEM drivers at once are delivered. Both work with all TOS
versions without hardware intervention.
DAVI - works without GDOS
GOLI - works with GDOS or AMCGDOS
* Wide ranging utilities (Night, Mouse Accelerator, Screen Dump to
SLM804, programming examples)
