Figure 3 shows a "Prompt"
monitor connected to the normal MTX Video output,
as well as the separate Power Supply Units
needed for the MTX Computer and SDX Disk Drive.
This diagram appears to show an MTX512S2 with an
attached SDX disk drive.
Some systems did not need the SDX drive - the
software could be installed in ROMs fitted to a
ROM expansion board in the computer.
Figure 4 shows a 16
screen Video Wall, using two "Black Magic"
Video Wall controllers, each driving eight
monitors and a single, 4 output, Video Decoder
The RGBS outputs
from the Decoder were fed to a pair of 15-pin
"D" type sockets on the Video Wall controllers,
one for each of the framestore controller boards.
The controller boards were multi-dropped on
the ribbon cable from the MTX printer port.
